In a decisive step toward ending HIV as a public health threat by 2030, Uganda on Thursday, May 29, 2025, officially launched the third Uganda Population-based HIV Impact Assessment (UPHIA 2025) survey, a nationally representative household study expected to provide updated measurements on the status of the HIV epidemic by the end of the year.
The effort is led by Uganda’s Ministry of Health (MoH), with technical assistance from Makerere University School of Public Health (MakSPH), Uganda Bureau of Statistics (UBOS), Uganda Virus Research Institute (UVRI), and the U.S. Centers for Disease Control and Prevention (U.S. CDC), funded by the U.S. government through PEPFAR.
The Population-based HIV Impact Assessment (PHIA) surveys were first launched in 2014 as a global initiative at the International Center for AIDS Care and Treatment Programs (ICAP), based at Columbia University’s Mailman School of Public Health. Supported by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), through the U.S. CDC, the surveys have been conducted in at least 15 high-burden countries globally, including Uganda.
Led by national Ministries of Health, the PHIA surveys provide robust, population-level data on HIV prevalence, incidence, and viral suppression, offering a clear picture of epidemic trends and the effectiveness of national responses. They are designed to track progress, identify persistent gaps, and inform strategies to reach epidemic control, in line with global targets, including the fast-approaching goal of ending AIDS as a public health threat by 2030.

In Uganda, this survey was first rolled out between August 2016 and March 2017. The second followed in February 2020 but was disrupted by the COVID-19 outbreak, continuing through to March 2021. Both rounds were supported by ICAP at Columbia University, which provided technical assistance to strengthen data collection systems, improve laboratory infrastructure, and build national capacity to design, implement, and analyse the two national HIV surveys.
What sets UPHIA 2025 apart is the shift in technical leadership to Ugandan institutions for this third survey, reflecting local capacity to lead rigorous, high-quality public health research. For UPHIA 2025, Makerere University School of Public Health, in partnership with the Uganda Bureau of Statistics and the Uganda Virus Research Institute, is providing technical leadership to the Ministry of Health, alongside U.S. CDC. Implementation began with initial recruitment and training of over 300 field teams that begun on May 19, 2025, ahead of their nationwide deployment for data collection starting this June.
The first survey (UPHIA 2016) was an important milestone in informing Uganda’s national HIV response. This survey, concluded in 2017, measured, among things, the viral load suppression at the population level and provided household-based HIV testing and counselling, with results returned to participants and those who tested positive referred to care. The survey also assessed HIV incidence, HIV and syphilis prevalence, as well as hepatitis B infection rates. These findings would offer nationally representative data to track Uganda’s progress in controlling the HIV epidemic at both national and regional levels.
The next survey, UPHIA 2020, building on past success, was again executed with technical leadership from Columbia University’s ICAP, working with Uganda’s Ministry of Health alongside UVRI, UBOS, regional referral hospitals, local governments, and the U.S. CDC. It offered useful insights that showed encouraging progress, indicating that up to 88% of people living with HIV in Uganda at the time knew their status, 98% of them were on treatment, and 90% had achieved viral suppression. These results reflected momentum toward the UNAIDS global 95-95-95 targets, ensuring that most people living with HIV are diagnosed, treated, and have the virus under control, and advancing the broader goal of ending the epidemic by 2030.
Since the release of these findings nearly five years ago, which helped shape national HIV programming in Uganda, the country has made notable progress, but challenges remain. The UPHIA 2020 findings reported major gaps in testing coverage, particularly among young people and men. The results were also instrumental in identifying service delivery shortfalls and guiding decisions on resource allocation, program design, and policy. Yet today, Uganda remains one of the most heavily burdened countries in the world, with over 1.5 million people living with HIV and over 50,000 preventable new infections recorded per year.

It is this trend that Uganda’s Ministry of Health is working urgently to reverse. Launching UPHIA 2025 at the Ministry’s headquarters in Kampala on May 29, 2025, amidst great hope and expectation among the participants, Uganda’s Minister of Health, Dr. Jane Ruth Aceng Ocero, noted that the long-anticipated and previously delayed survey had arrived at such a critical moment. She welcomed UPHIA 2025 as both a measure of the country’s resilience and a guide for the final stretch toward ending AIDS by 2030, now just a few years away.
“The UPHIA 2025 survey comes at a strategic time to help us recalibrate and refocus our efforts,” the Health Minister said, underscoring the importance of its outcomes. “This will be Uganda’s final population-based HIV survey before 2030, the target year for ending AIDS as a public health threat. The findings will serve as a baseline for tracking our progress toward this national and global goal. They will also guide the next phase of strategic planning, ensuring that the final push toward 2030 is grounded in robust and reliable data.”
This third round of the survey will be carried out in 6,685 randomly selected households across the country. The exercise will involve interviews with approximately 15,000 individuals aged at least 15 and selected through a national household listing by UBOS. Of those, around 14,980 are expected to provide blood samples for HIV testing and analysis of viral suppression and other health indicators. The survey will also include interviews with 1,300 children and adolescents aged 10 to 14, though no blood draws will be taken from this group. Participation is voluntary, free of charge, and requires consent from the head of each household.
MakSPH’s Assoc. Prof. Fredrick Makumbi, the Principal Investigator for UPHIA 2025 survey, consults with MoH’s Commissioner for Human Resource Management, Ms. Annet Musinguzi, during the kick-off of training of UPHIA 2025 field teams at MakSPH New Auditorium on 19th May, 2025.
Dr. Aceng explained that beyond providing updated estimates of HIV prevalence, incidence, and viral load suppression, and examining regional and demographic disparities, the survey, which will cover the rest of the year, will include a qualitative post-survey assessment component to gather insights from people living with HIV, particularly those not virally suppressed, to understand their challenges and strengthen support services. Also, for the first time, this survey will assess the burden of non-communicable diseases among people living with HIV and include focused interviews with adolescents aged 10 to 14 in Mid-North and Mid-Eastern Uganda, where viral suppression was reported to be lowest in UPHIA 2020.
These activities are made possible thanks to the development support from the U.S. government, which invested $10 million (about UGX 37 billion) for this survey. Speaking at the UPHIA 2025 launch, U.S. Ambassador to Uganda William W. Popp noted that the United States has partnered with Uganda for over three decades to help people live longer, healthier lives;
“The bulk of our annual support, approximately $500 million this year, is dedicated to health programs, making the U.S. government the largest single provider of health assistance to Uganda,” the Ambassador said. He added, “Through PEPFAR, the United States has played a major role in Uganda’s progress toward ending HIV as a public health threat. Since 2003, when Uganda became one of the first countries to implement the program, we have invested nearly three billion dollars—almost 11 trillion Uganda shillings—in HIV prevention, care, and treatment services, saving millions of lives and making both our countries safer from HIV.”
At the UPHIA 2025 launch, Ambassador Popp emphasised the enduring U.S.-Uganda partnership in advancing public health.
With the benefit of hindsight, Uganda’s early encounter with HIV in the 1980s marked the beginning of one of the region’s most severe epidemics. But over the decades, a determined national response, driven by political leadership, community mobilisation, collaboration and global support, has delivered measurable progress. In the recent past, adult HIV prevalence fell from 7.2% in 2010 to 5.1% in 2023. Among women, it declined from 8.5% to 6.6%, and among men from 5.8% to 3.6%. AIDS-related deaths dropped from 53,000 to 20,000 over the same period, with female mortality declining by 66% and child deaths by 77%.
All these gains, amidst the challenge, go to show what is possible with sustained commitment. What is more, throughout this long journey of Uganda’s battle with eradicating HIV, Makerere University School of Public Health has played a pivotal role. From the early work of Prof. David Serwadda, whose ground-breaking research during the initial detection of HIV helped shape Uganda’s early response, to last year’s 2024 landmark Purpose 1 study on the twice-yearly injectable Lenacapavir that proved 100% efficacy in preventing HIV infection, MakSPH has remained at the forefront of innovation, evidence generation, and policy influence.
That legacy continues today, with the School providing technical leadership to the Ministry of Health in the implementation of UPHIA 2025. At the launch, MakSPH Dean Prof. Rhoda Wanyenze expressed pride in the School’s role as a trusted partner in Uganda’s fight against HIV and other public health challenges. She noted that for over 70 years, during which the School has existed, MakSPH has helped shape the country’s public health landscape through rigorous research, training, and policy support, anchored by a strong, long-standing partnership with the Ministry of Health and partners.
At the UPHIA 2025 launch, Prof. Rhoda Wanyenze highlights MakSPH’s legacy in shaping Uganda’s public health landscape through rigorous research and policy support.
She also noted that the collaboration between Makerere University and the U.S. CDC has helped build national capacity in surveillance and epidemiology, while also strengthening Uganda’s ability to lead high-quality, large-scale national surveys, asserting that:
“The partnership between Makerere University and CDC has not only helped build national capacity in surveillance and epidemiology, but has also strengthened our ability to lead high-quality, large-scale national surveys. After two decades of joint work, we are proud that UPHIA 2024–2025 is now a fully Ugandan-led effort. This is critical to the sustainability of the skills and knowledge generation to inform our local response.”
The survey builds on MakSPH’s experience conducting similar national studies, including those on tuberculosis, prison health, family planning, schistosomiasis, and non-communicable diseases such as the STEPS survey. It will leverage the School’s strong capacity in research and impact evaluation, both in Uganda and across the African region, with a firm commitment to delivering high-quality data guided by the same rigour and integrity that have defined our work over the years, Prof. Wanyenze affirmed.
In many low- and middle-income countries, mortality data remains a critical gap in public health planning, often leaving a significant portion of the population “invisible” in official records. In Uganda, where national death registration completeness has historically hovered around a mere 20%, Makerere University Centre for Health and Population Research (MUCHAP) is leading a transformative initiative. By leveraging the infrastructure of the Health and Demographic Surveillance System (HDSS), MUCHAP has demonstrated how academic research frameworks can be integrated into national systems to strengthen Civil Registration and Vital Statistics (CRVS).
A Bridge between research and governance
The core of this success lies in the collaboration between Makerere University’s infrastructure and government agencies, specifically the National Identification and Registration Authority (NIRA). This partnership, supported by the Uganda National Public Health Institute (UNPHI) and international partners like the Bloomberg Philanthropies Data for Health Initiative at the CDC Foundation, aimed at aligning local death recording practices with the legal requirements of the Registration of Persons Act (ROPA) 2015.
By utilizing the existing MUCHAP Iganga Mayuge HDSS platform, which has monitored births and deaths in the Iganga and Mayuge districts since 2005, the project demonstrated the use of a decentralized notification process. This model utilises Village Health Teams (VHTs) who already serve as HDSS scouts and part of the Ministry of Health systems as official death notifiers. These VHTs assist households in completing official NIRA notification forms at the household/community level, which are then verified by local leaders and submitted to District Registration Offices.
Impact: From 20% to over 70% completeness
The results of this collaboration have been profound. In the pilot sub counties in the districts of Iganga and Mayuge, death registration completeness reached 73–79%, a dramatic improvement over the prevailing national estimates. During the study period, 2,992 deaths were officially registered within the national CRVS system.
Key drivers of this success included:
Reduced barriers: Decentralization brought the registration process closer to home, with an average travel distance of only 4–5 km for notification, compared to the significant distances previously required to reach district offices.
Cost savings: Families reported that the community-based process eliminated unofficial fees and high transportation costs, facilitating essential cultural and legal tasks like property inheritance and appointing heirs.
Advanced surveillance: The project proved that local health personnel could successfully conduct verbal autopsies (VA) in non-HDSS settings, providing critical data on causes of death that were previously unavailable for home-based deaths.
Sustainability and future potential
The MUCHAP-IMHDSS model is designed for long-term sustainability and national scalability. By embedding these tasks within the routine activities of VHTs and local leaders, the process becomes streamlined and cost-effective over time. The project also highlights that community sensitization is vital to maintaining trust and ensuring high participation rates, particularly in rural areas.
Looking forward, this initiative serves as a scalable blueprint for the rest of Uganda and other low-resource settings. Future engagements are expected to focus on:
National scale-up: Applying the lessons learned from Iganga and Mayuge to the entire country to close the mortality surveillance data gap.
Integration with health systems: Linking the CRVS data with broader health information systems to enhance pandemic preparedness and routine public health actions.
Regional leadership: Aligning with the Africa CDC’s initiative to strengthen mortality surveillance across the continent, positioning Uganda’s university-led model as a regional gold standard.
The HDSS-CRVS integration Project Leader Dr. Dan Kajungu who is the Executive Director of MUCHAP emphasised that “through this work, Makerere University has again proved that academic infrastructure is not just for research, but a vital engine for building resilient national governance and health systems”.

World Malaria Day 2026: Makerere scientists have found the countdown clock for when Ugandan children will die from malaria: The question is whether anyone is listening
On a day when the world declares it can and must end malaria, new research from Eastern Uganda shows climate change is working against us and that the evidence to fight back exists right here at home
Special Feature | World Malaria Day, 25 April 2026
By Health and Science Correspondent
Today, 25 April 2026, Uganda joins the rest of the world in marking World Malaria Day under the global theme: “Driven to End Malaria: Now We Can. Now We Must.” It is a rallying cry rooted in genuine optimism. Since 2000, 2.3 billion malaria cases and 14 million deaths have been averted globally. Forty-seven countries have been certified malaria-free, and between 2000 and 2024, the number of malaria-endemic countries fell sharply from 108 to 80.
Uganda is not one of those success stories, not yet. Malaria is endemic in 96% of Uganda, accounting for 29.1% of outpatient visits and 39.5% of hospital admissions, with over 17,556 estimated malaria deaths annually, the highest burden falling on children under five years of age. And on this World Malaria Day, a new alarm has been sounded from the heart of one of Uganda’s most malaria-burdened communities, not by foreign researchers, not by a distant global health organisation, but by scientists at Makerere University, drawing on two decades of data they have collected in the villages of Iganga and Mayuge in Eastern Uganda.
Their message is urgent: climate change is silently and measurably worsening Uganda’s malaria crisis. But this is the equally important half of the story. They have now identified the precise conditions under which children die, and exactly how long in advance those deaths can be predicted. Uganda has, for the first time, a scientifically validated early warning system for climate-driven malaria mortality. Whether the country chooses to use it is now a question of political will, not scientific capacity.
The study and the platform that made it possible
Published in BMC Public Health in August 2025, the study — “Climate-driven malaria mortality among children in malaria-endemic areas of Uganda” — was led by Dan Kajungu of Makerere University‘s Centre for Health and Population Research (MUCHAP). It analysed 14 years of weekly malaria death data from January 2008 to December 2022 matched against climate variables, using a sophisticated time-series statistical approach called the Distributed Lag Non-linear Model.
The data came from the Iganga Mayuge Health and Demographic Surveillance Site (IMHDSS), the population research platform that Makerere University has operated continuously since 2005. The IMHDSS population cohort collects data from 65 villages located within an area of 155 square kilometres, monitoring a population of close to 100,000 people. The site has 23 health facilities, including two general hospitals, and a bimodal tropical climate with rainfall seasons from March to May and September to November.
What makes the IMHDSS extraordinary and what made this study possible is its method of capturing deaths. Rather than relying on hospital registers that miss the majority of rural deaths, malaria deaths were identified using verbal autopsies and the InterVA algorithm, a probabilistic tool that uses verbal autopsy questionnaires and Bayesian statistical techniques to estimate the probabilities of various causes of death based on signs and symptoms reported by bereaved families. Three different WHO verbal autopsy tools are used, tailored for neonates, children, and adults respectively.
In other words, when a child dies in a village in Iganga, the IMHDSS knows about it. It interviews the family. It determines why the child died. And it has been doing this, without interruption, for twenty years. The result is a dataset that is both scientifically rare and profoundly Ugandan, generated here, about us, by our own researchers.
A total of 858 malaria-related deaths were recorded in the Iganga-Mayuge districts between 2008 and 2022. Of these, 53% were among males and 47% females. The vast majority, about 73% occurred among children under five years of age, while the fewest deaths occurred among those aged 15 to 49 years. Males exhibited higher mortality proportions across all age groups, except among the elderly.
Eight hundred and fifty-eight deaths. Each one a child or adult with a name, a family, a community. Each one counted.
The finding that changes everything: Uganda now has a malaria early warning system
The scientific heart of this study, the finding that every health planner, every district malaria coordinator, and every Minister of Health in Uganda should understand is this: the researchers have identified the exact temperature and rainfall thresholds at which malaria deaths among children rise, and how many weeks in advance those deaths can be predicted.
The study found an increased mortality risk across all ages at a lag of 11 to 12 weeks following exposure to rainfall above 646 mm. Higher risks of malaria mortality were also observed at a lag of 5 to 11 weeks when temperatures ranged between 25.2°C and 29.9°C. Critically, the relative risk of malaria mortality in children under five years and children aged between 5 and 14 years was more sensitive to temperature than to rainfall.
Read that again, slowly. When temperatures in Eastern Uganda climb into the range of 25.2°C to 29.9°C, children begin dying of malaria five to eleven weeks later. When extreme rainfall events exceed 646 mm, deaths rise eleven to twelve weeks after that exposure. Uganda’s meteorological service measures temperature and rainfall continuously. Uganda’s health system manages malaria interventions. These two systems have never been formally connected, but the science to connect them now exists.
This is what a malaria early warning system looks like. Not a foreign technology imported at great expense. Not a satellite system requiring international expertise to interpret. A Ugandan scientific finding, produced from Ugandan data, that tells Ugandan health authorities: when you see these weather conditions, stock your health centres, distribute your bed nets, deploy your community health workers, and prepare, because the deaths are coming in six to twelve weeks if you do not act.
On this World Malaria Day, when the global community declares that ending malaria is now possible, Uganda has precisely this tool in its hands. The only question is whether it will use it.
Climate change is not a future threat, it is already killing children
The global theme for World Malaria Day 2026 carries urgency partly because climate change, conflict, and humanitarian crises continue to drive malaria resurgence and disrupt essential services. The Makerere study puts specific, local flesh on that global warning.
Malaria is climate-sensitive, changes in temperature, rainfall patterns, and relative humidity affect the dynamics and intensity of malaria transmission by influencing the habitats of mosquitoes and parasites and their biological growth cycle. Climate remains an indirect cause of malaria mortality by affecting parasite development during periods of high rainfall and temperatures, leading to increased transmission, morbidity, and severe malaria outcomes.
The malaria parasite Plasmodium falciparum, the species responsible for almost all malaria deaths in Uganda requires specific temperature ranges to complete its development inside the Anopheles mosquito. Too cold, and development slows or stops. Too hot, and it also stops. But within the range that Eastern Uganda increasingly inhabits, and will inhabit more frequently as global temperatures rise, the parasite thrives, multiplies, and kills.
The World Malaria Report 2025 warns that drug resistance is now confirmed in four African countries including Uganda, where artemisinin partial resistance has been detected. Insecticide resistance to pyrethroids – the main chemical on bed nets is now confirmed in 48 out of 53 reporting countries. As the tools Uganda currently relies on including bed nets, indoor spraying, artemisinin-based drugs face mounting biological resistance, the importance of climate-informed prevention strategies grows exponentially. Deploying interventions at exactly the right time, guided by weather data, becomes not just efficient but essential.
The children most at risk: a finding that demands a policy response
Among the study’s most striking findings is the specific vulnerability of school-age boys. A group almost entirely absent from Uganda’s current malaria prevention architecture.
Male children aged between 5 and 14 years were found to be more vulnerable to temperature-related malaria mortality compared to females in that age group and compared to children under five years. Rainfall did not have a significant association with malaria mortality in children.
Uganda’s National Malaria Control Programme, like most in sub-Saharan Africa, has historically concentrated resources on two priority groups: children under five and pregnant women. These groups are undeniably vulnerable and deserve protection. But this study shows that school-age boys are dying from temperature-driven malaria at rates that demand their inclusion in prevention strategies.
School-aged children between 5 and 14 years have higher malaria prevalence, with 70% carrying the malaria parasite asymptomatically in high transmission settings. They carry the parasite silently, sustaining transmission in their communities, and they die when temperatures rise, particularly the boys, who in rural Uganda spend more time outdoors, sleep less consistently under nets, and receive less parental health supervision than their sisters as they grow older.
The study’s area is itself among the most heavily burdened in Uganda. The Iganga-Mayuge area has a malaria prevalence rate of 39.4% in children under five years old, making it one of the areas in Uganda most severely impacted by malaria, and the disease is the leading cause of mortality in children there. In such a high-transmission setting, the combination of asymptomatic carriage, temperature-driven transmission spikes, and inadequate prevention coverage for school-age children is a formula for preventable death.
On World Malaria Day 2026, as Uganda declares its commitment to ending malaria, the national malaria strategy must be updated to reflect this evidence. School-based distribution of insecticide-treated nets, school health programmes that include malaria education and early symptom recognition, and targeted community outreach for families with boys aged 5 to 14 are not optional additions, they are evidence-based necessities.
The platform: Makerere‘s IMHDSS as a national asset for malaria elimination
None of the findings in this study would have been possible without the IMHDSS and on World Malaria Day, it is worth being explicit about what that platform represents for Uganda’s future.
The IMHDSS platform has measured various indicators about coverage and uptake of national interventions including the coverage and utilisation of immunisation and vaccines, mosquito nets for malaria vector control, household income improvement, and family planning, and other behaviour change interventions at community level, strengthening the evaluation of burden of disease at the subnational level.
For malaria specifically, the IMHDSS has now produced the most granular mortality data in Uganda’s history capturing not just how many children die, but exactly which weather conditions preceded those deaths, which sex and age group is most vulnerable, and what the biological and epidemiological mechanisms are that connect climate to the grave. This is the kind of intelligence that a National Malaria Control Programme needs to move from reactive crisis management to proactive, evidence-driven prevention.
Scarcity of quality data remains a key development bottleneck in low and middle-income countries, and the Iganga-Mayuge HDSS represents a Makerere University platform for research and research training with a population-based cohort that longitudinally generates data for evidence-based decisions and policy.
Uganda’s malaria elimination goal, to bring mortality to zero will not be achieved by effort and goodwill alone. It requires data. It requires the kind of longitudinal, community-level, cause-of-death data that only a platform like the IMHDSS can generate. And it requires the institutional will to connect that data to the decisions that determine whether children live or die.
What must happen now
The global call on World Malaria Day 2026 is clear: “Now We Can. Now We Must.” For Uganda, the Makerere climate-malaria study translates that call into three specific and achievable actions.
First, the Ministry of Health and Uganda National Meteorological Authority must establish a formal, operational malaria early warning system. One that uses real-time weather monitoring to trigger predetermined health system responses when temperature and rainfall thresholds identified by this research are breached. The science is ready. The infrastructure for meteorological monitoring exists. What is needed is the institutional bridge between them.
Second, Uganda’s National Malaria Control Programme must extend its prevention focus to include school-age children, particularly boys aged 5 to 14, in all high-transmission areas. Bed net campaigns must reach schools, not just health centres and antenatal clinics. Community health workers must be equipped to identify and treat malaria in this age group as a priority.
Third, and most fundamentally, the Government of Uganda must formally recognise and domestically resource the IMHDSS as national public health infrastructure. The 2024 global malaria funding of US$3.9 billion was less than half of the US$9.3 billion target, leaving a projected shortfall of US$5.4 billion that leaves the response dangerously under-resourced. In a world where international health financing is under historic pressure, Uganda cannot afford to have its most powerful evidence-generation platform dependent entirely on foreign philanthropy. The IMHDSS is a Ugandan asset. It must be funded as one.
Today, children in Iganga and Mayuge are alive who might not be, because the research generated by the IMHDSS informed the malaria interventions that reached their communities. Today, Makerere scientists have given Uganda a tool, a climate-based early warning system for malaria deaths that no other country in East Africa currently possesses.
Now we can. Now we must.
The evidence is there. The science is done. The only thing Uganda needs now is the will to act on it.

A joint study between Makerere University School of Public Health (MakSPH) and The Open University, UK, is investigating a possible link between maize cultivation and malaria risk in Uganda, as evidence increasingly points to livelihoods and everyday economic activities as key drivers of transmission of the disease.
The research initiative was advanced during a stakeholders’ workshop held on April 15, 2026, at MakSPH’s Resilient Africa Network in Kololo, where a team led by Assoc. Prof. David Musoke of Makerere University and Dr. Kevin Deane of The Open University presented ongoing and previous findings on the social determinants of malaria. The meeting brought together academics, policymakers, and practitioners to examine how agricultural practices, particularly maize farming, may be shaping malaria patterns in both rural and urban settings in Uganda.
The work builds on a growing body of research linking malaria to economic activity. One such study, led by the two researchers and published in Global Public Health in December 2025, found that livelihood activities such as farming, livestock keeping, and night-time work significantly influence malaria exposure. The study identified agriculture, especially maize cultivation near homes, as a key factor associated with increased mosquito density and heightened infection risk.
Assoc. Prof. David Musoke presents research findings on how livelihoods, including maize cultivation near homes, may influence malaria exposure during a stakeholder workshop at the Resilient Africa Network, Kololo, on April 15, 2026.
At the workshop, Dr. Musoke said the new inquiry reflects a broader shift in how malaria is understood, outlining how livelihoods, particularly agriculture, shape exposure through multiple pathways, from crop production and water use to the timing of daily activities that coincide with peak mosquito biting hours. These patterns, he argued, extend risk beyond what conventional interventions, such as insecticide-treated nets and indoor spraying, are designed to address.
Uganda remains one of the countries most affected by malaria, with the disease accounting for a significant share of outpatient visits, hospital admissions, and deaths. It is consistently ranked among the leading causes of illness and mortality, particularly among children under five and pregnant women. Despite sustained investment in prevention and treatment, including widespread distribution of insecticide-treated nets and indoor residual spraying, transmission remains high in many parts of the country. This persistence has increasingly drawn attention to factors beyond conventional interventions, including the role of livelihoods, environment, and everyday exposure to mosquitoes.
Maize grown close to homes, with damp ground conditions, may increase exposure to malaria in rural communities.
“As researchers, our role is to generate evidence, and that evidence should inform decision-making,” Dr. Musoke said. “We do not work in isolation. What we hear from stakeholders matters. We are bringing together different sectors, disciplines, and institutions because this work is still in progress, and we intend to build it collaboratively. Increasingly, research requires not just academics, but policymakers, implementers, and communities to be part of the process.”
The collaboration with The Open University has been central. Dr. Deane said the idea of examining the relationship between maize and malaria emerged from several years of joint research on social determinants with MakSPH. He pointed to a gap in malaria research, which has largely focused on biomedical and indoor interventions, while overlooking the role of livelihoods and outdoor exposure.
Assoc. Prof. David Musoke (left), Dr. Paul Mulumba (centre), a Health Inspector in Wakiso District, and Dr. Kevin Deane (right) share insights during the workshop at the Resilient Africa Network, Kololo, on April 15, 2026.
“We cannot continue relying solely on bed nets, spraying, and treatment,” Dr. Deane said. “These remain essential, but they are not sufficient for elimination. There is significant outdoor malaria transmission, particularly among adults, and that is linked to how people live and work.”
He added that maize presents a complex case. As one of Uganda’s most widely grown staple crops, it is central to both food security and household income, making it impractical to separate farming from living spaces. This, he said, underscores the need to better understand the relationship and develop responses grounded in evidence and local realities.
Evidence presented during the workshop drew on both community experiences and existing scientific literature. Prior qualitative research by the team found that mosquito populations increase during maize growing seasons, particularly in the evenings. Scientific studies also show that maize pollen can enhance mosquito survival and longevity, potentially increasing their capacity to transmit malaria.
Dr. Kevin Deane of The Open University emphasised the need to move beyond conventional malaria interventions to better understand how livelihoods and everyday activities shape exposure during the stakeholder workshop in Kololo, Kampala, on April 15, 2026.
Previous work in Wakiso district further situates maize within a wider set of risk factors. Findings show that agriculture, including crop production and animal husbandry, can create conditions that support mosquito breeding through stagnant water, water storage practices, and environmental changes. These risks are compounded by outdoor activities in the early morning and evening, when exposure is highest. The research also points to the growing role of urban agriculture, which is bringing crop cultivation and potential mosquito habitats closer to residential spaces, altering traditional patterns of transmission.
Ms. Doreen Nabwire Wamboka, in-charge at Namayumba Epicentre Health Centre III in Wakiso District, said the discussions challenged long-held assumptions that malaria is a “well-understood” condition.
“I used to think malaria had been fully researched, that we already knew what we needed to know,” she noted. “I now see that what has been studied is the conventional side of it. There are emerging factors we have not paid attention to. This work is opening up new ways of thinking, even about things we take for granted, like the crops we grow around our homes. We treat malaria as ordinary, yet it is still one of the most common conditions. Understanding these connections could change how we approach the disease.”
Ms. Doreen Nabwire Wamboka, In-charge at Namayumba Epicentre Health Centre III in Wakiso District, engages in a co-creation session as a fellow participant looks on during the stakeholder workshop in Kololo on April 15, 2026, underscoring the need for collaborative approaches to design interventions to tackle malaria.
The initiative will now combine spatial analysis, entomological studies, and community-based research to better understand how maize cultivation influences malaria risk. It will also involve farmers and other stakeholders in shaping potential interventions, reflecting a broader shift toward co-produced solutions.
The workshop, funded by The Open University, marked an important step in refining this research agenda. As the work progresses, its findings could inform policy and practice not only in Uganda, but also in other malaria-endemic countries where maize is widely cultivated. For now, the research signals a shift from isolated interventions to a more integrated understanding of how livelihoods and environments drive malaria transmission.
