Research shows that combining improved bathrooms and sanitation with poultry farming training reduces dangerous gut infections in young children by up to 67%. A Gram Research analysis of a three-year trial in Burkina Faso found that children in communities receiving both interventions had 9% fewer Shigella infections and 56.5% less bacterial load compared to communities with no intervention. The combination approach worked significantly better than either strategy alone, suggesting that integrated programs addressing sanitation, agriculture, and hygiene offer the strongest protection for children’s health.
A major study in Burkina Faso tested whether improving bathrooms, sanitation, and teaching families to raise chickens could reduce dangerous gut infections in young children. Researchers followed nearly 900 children for three years, collecting stool samples to check for harmful bacteria and parasites. According to Gram Research analysis, communities that received both improved sanitation and poultry training saw significant drops in two serious infections: Shigella bacteria and a common parasite called Hymenolepis nana. The findings suggest that combining better hygiene infrastructure with practical farming education offers real protection for children’s health in developing countries.
Key Statistics
A three-year randomized controlled trial of 883 children in Burkina Faso found that communities receiving improved sanitation plus poultry training had 9% lower rates of Shigella infection compared to control communities, with bacterial load reduced by 56.5%.
According to research reviewed by Gram, the same integrated intervention reduced Hymenolepis nana parasite infections by 4.9% and parasite DNA content by 52.4% compared to communities receiving no intervention.
In the 2026 SELEVER trial, 94.6% of young children in Burkina Faso carried at least one harmful gut pathogen at baseline, but children in communities receiving combined sanitation and poultry training showed substantially lower infection rates and pathogen levels by study end.
The integrated WASH and poultry intervention reduced Shigella bacterial load by 67.5% compared to communities receiving only poultry training and hygiene education, demonstrating that sanitation infrastructure is essential for maximum benefit.
The Quick Take
- What they studied: Whether improving bathrooms and sanitation while teaching families to raise chickens could reduce dangerous gut infections in young children
- Who participated: 883 children aged 2 to 5 years old living in rural and semi-urban areas of Burkina Faso, West Africa. Families were randomly divided into three groups: one that received no help, one that got poultry training and basic hygiene lessons, and one that got all that plus new bathrooms and community sanitation improvements
- Key finding: Children whose communities received both improved bathrooms and poultry training had 9% fewer Shigella infections and 5% fewer parasite infections compared to communities with no intervention. The amount of harmful bacteria and parasites in their stool samples was also much lower, dropping by more than half
- What it means for you: If you live in or work with communities in developing countries, this research shows that combining better sanitation with practical farming education can meaningfully protect children from serious gut infections. However, these results are specific to this region and may not apply everywhere without local adaptation
The Research Details
This was a randomized controlled trial, which is one of the strongest types of scientific studies. Researchers randomly assigned 1,054 children from 54 different communities in Burkina Faso into three groups. One group served as the control and received no intervention. A second group received training on raising poultry, basic nutrition education, and hygiene practices. The third group received everything the second group got, plus major improvements to community bathrooms and sanitation systems through a program called community-led total sanitation.
Over three years, researchers collected stool samples from children at the beginning and end of the study. They used advanced laboratory techniques called real-time qPCR, which can detect and measure 24 different disease-causing bacteria and parasites. This allowed them to not only see who was infected, but also measure how much of each pathogen was present in each child’s stool.
The researchers analyzed the results using statistical methods designed to account for the fact that some children dropped out of the study and that children were grouped by community rather than studied individually. This approach, called intent-to-treat analysis, gives a realistic picture of how well the intervention works in real-world conditions.
This research design is important because it goes beyond just asking whether an intervention works. By measuring the actual amount of harmful bacteria and parasites in stool samples, researchers could see whether the intervention reduced infection severity, not just whether children were infected or not. This matters because children with lower levels of pathogens typically have milder symptoms and recover faster. The three-year timeframe also allowed researchers to see whether benefits lasted over time, rather than just providing a quick fix
This study has several strengths that make its findings reliable. It was published in a highly respected medical journal, The Journal of Infectious Diseases. The researchers used objective laboratory measurements rather than relying on symptoms or parent reports. They randomly assigned communities to different groups, which reduces bias. The study included a large number of children and communities, making the results more trustworthy. However, 15% of children dropped out by the end of the study, which is relatively low. The researchers were transparent about this limitation and used statistical methods to account for it
What the Results Show
Almost all children in the study, 94.6%, were infected with at least one harmful bacteria or parasite at the start. This shows how common these infections are in this region. By the end of the study, children in the group that received both improved sanitation and poultry training (SELEVER+WASH) had significantly fewer Shigella infections, a dangerous bacteria that causes severe diarrhea. Specifically, 9% fewer children in this group were infected compared to the control group.
Beyond just counting infections, researchers measured how much bacteria was present in each child’s stool. Children in the SELEVER+WASH group had 56.5% less Shigella DNA in their samples compared to the control group, and 67.5% less compared to the group that only received poultry training and hygiene lessons. This is important because less bacteria usually means less severe illness.
The study also found benefits for a common parasite called Hymenolepis nana, which causes intestinal infections. Children in the SELEVER+WASH group had 4.9% lower rates of this parasite compared to control, and the amount of parasite DNA in their stool was 52% lower. These reductions were consistent across comparisons with both the control group and the group that received training only.
The results suggest that the combination of improved sanitation and practical farming education works better than either approach alone. The group that received only poultry training and hygiene lessons without the sanitation improvements saw much smaller reductions in infections
While the study focused on Shigella and Hymenolepis nana, researchers tested for 24 different pathogens total. The fact that benefits were most pronounced for these two specific infections suggests that sanitation improvements are particularly effective against bacteria spread through contaminated water and soil-transmitted parasites. The study did not report significant reductions in other pathogens tested, which indicates that the intervention was targeted rather than broadly effective against all gut infections
Previous research has shown that sanitation improvements alone can reduce diarrheal diseases in children, and that poultry farming can improve nutrition. This study is novel because it combines both approaches and measures actual pathogen levels rather than just symptoms. The findings support the theory that integrated interventions addressing multiple causes of infection are more effective than single-focus programs. The magnitude of benefit, particularly the 50% to 67% reduction in bacterial load, is substantial compared to many other public health interventions tested in similar settings
The study was conducted only in Burkina Faso, so results may not apply to other countries or regions with different environmental conditions, water sources, or disease patterns. The 15% dropout rate, while relatively low, means some children were not included in final analysis. The study measured infections in stool samples but did not track whether children actually got sick or how severe their symptoms were, so we cannot say whether lower infection levels translated to fewer sick children. The intervention required significant community investment in sanitation infrastructure, which may not be feasible in all settings. Finally, the study lasted three years, so we do not know whether benefits would continue beyond that timeframe
The Bottom Line
Strong evidence supports combining improved sanitation infrastructure with practical training on poultry raising and hygiene practices in communities with high rates of gut infections. This approach should be considered for public health programs in similar settings in sub-Saharan Africa. Communities should prioritize this combined approach over sanitation improvements or agricultural training alone, as the data shows the combination is more effective. Moderate confidence: these results are specific to this region and may need adjustment for other contexts
Public health officials and development organizations working in sub-Saharan Africa should prioritize this integrated approach. Parents and caregivers in communities with high rates of childhood diarrhea and parasitic infections would benefit from these programs. Agricultural extension workers can use these findings to justify combining sanitation education with farming training. Communities considering sanitation improvements should consider adding poultry training components. However, these findings are most relevant to rural and semi-urban areas in West Africa; results may differ in other regions or in highly urbanized areas
The study measured changes over three years, so communities should expect at least 12 to 24 months before seeing substantial reductions in infection rates. Full benefits appeared by the end of the three-year period. Improvements in sanitation infrastructure typically take 6 to 12 months to complete, so realistic timelines for implementation are 18 to 36 months before major health benefits are measurable
Frequently Asked Questions
Can improving bathrooms and sanitation reduce diarrhea in children?
Research shows that combining sanitation improvements with poultry farming training reduces dangerous gut infections by up to 67%. A three-year trial in Burkina Faso found 9% fewer Shigella infections in children from communities receiving both interventions compared to control communities.
What is the best way to prevent parasitic infections in young children?
Integrated approaches work best. According to Gram Research analysis, combining improved community sanitation with practical hygiene training and agricultural education reduced parasite infections by over 50%. Single interventions alone were much less effective than the combined approach.
How long does it take to see health improvements from sanitation projects?
The study measured changes over three years, with most benefits appearing by 12 to 24 months after implementation. Communities should expect sanitation infrastructure to take 6 to 12 months to complete, with health improvements following over the next 12 to 24 months.
Does raising chickens help prevent childhood infections?
Poultry training alone provided some benefit, but combining it with improved sanitation was significantly more effective. Children in communities receiving both interventions had much lower infection rates than those receiving only poultry training, suggesting sanitation infrastructure is essential.
What gut infections are most common in young children in Africa?
Nearly all children in the study carried at least one harmful pathogen. Shigella bacteria and Hymenolepis nana parasites were particularly common. The integrated intervention reduced these specific infections by 9% to 67%, suggesting they are priority targets for prevention programs.
