A Life of Care
“My days begin with caring for my family and end with caring for my community,” says Louise Marie Mukarugwiza, a mother of six from Nyamagabe District, Rwanda.
For nearly a decade, Louise served her community as a Community Health Worker (CHW), focusing on maternal and child health. She visited households to weigh infants, encourage vaccinations, and counsel parents on nutrition. But when she joined a One Health Team (OHT) in 2024, her work expanded in ways she never expected.
In fact, Louise is one of more than 550 OHT members (to date) trained through COHERS across Rwanda and Senegal, building a network of local leaders equipped to stop diseases before they spread.
“Before, I never thought about how animals or even the environment could affect human health. Now I see the connection every day,” she explains.

Why One Health Matters in Rwanda
In rural Rwanda, families depend on pigs for both food and income. But when sanitation is poor and animals roam freely, the pork tapeworm, Taenia solium, can spread quickly—moving from pigs into people, where it can cause serious illness, even seizures and death.
For women and girls, the stakes are particularly high. They shoulder the daily work of caring for animals, fetching water, preparing meals, and maintaining hygiene—roles that leave them most exposed to infection, while often having the least access to health resources or decision-making power.
This is the challenge Louise confronts each day. As an OHT member, she helps families see how hygiene, safe pig husbandry, and shared household responsibilities are not just chores—they are life-saving practices that protect entire communities.
Learning One Health
Through COHERS, Louise and her fellow OHT members received a 10-module training series that explored the interconnections between people, animals, and the environment. Modules covered everything from zoonotic disease recognition to WASH (water, sanitation, and hygiene) practices, to gender equality and household decision-making.

OHTs themselves are multi-disciplinary, combining CHWs like Louise with Community Animal Health Workers and WASH facilitators. This design ensures that each team can address health holistically: human, animal, and environmental.
That knowledge has transformed the way Louise advises families.
She remembers visiting one household with three pigs—one of them small and weak. She shared what she had learned during OHT training: pigs, like people, need proper food, clean conditions, and a pen to thrive. The family built a pigsty and improved their feeding practices. Within weeks, the pig began to grow strong.
“Seeing that pig recover gave me so much pride. It showed me that the training works—and that I can help families change their future.”
Gender Equality Begins at Home
Louise admits that changing minds is often the hardest part of her role. Some farmers hesitate to vaccinate or deworm pigs, fearing that an ear tag might lower the animal’s value. Others resist changes to long-held traditions.
To spark dialogue, Louise joins her OHT colleagues in lively gender skits at community meetings. Through humor and storytelling, the skits tackle sensitive issues—like unequal household workloads, poor sanitation, and free-roaming pigs—and then model healthier, more equitable practices. “When people see themselves in the story, it opens the door for conversation and change,” Louise says.

She also brings lessons home. After receiving gender training through the OHT, she shared it with her husband. “He now realizes that when we are able to take on more livestock, he needs to play a role and share the work with me,” she says.
“That conversation changed things for us. He understands that health and livelihoods are stronger when men and women share the work.”
Changing Norms Through Hygiene and Sanitation
The OHTs aren’t working alone. Community Hygiene Clubs (CHCs)—made up mostly of women like Louise’s neighbor Josephine—reinforce the same lessons through weekly gatherings. Using songs, picture cards, and peer-to-peer learning, CHCs spread knowledge about hygiene, sanitation, nutrition, and animal management to hundreds of households.
These clubs also model practical solutions: tippy taps for handwashing, disinfected footbaths, safe waste management, and latrines built or upgraded with community support. Members emphasize “leading by example” in their own homes, making hygiene visible and achievable for their neighbors.

Together, OHTs and CHCs are creating ripple effects that go far beyond any one training or household visit. They are building a shared culture of prevention, cooperation, and One Health in action. The result is a shared “handwashing culture” that is changing norms in Nyamagabe.
This work has been critical in preparing communities for larger health campaigns. In Nyamagabe District alone, OHTs helped pave the way for a recent mass drug administration that reached more than 4,400 people with treatment against Taenia solium.
Building Evidence for the Future
Louise’s day-to-day work is not just about advising families—it is also part of something much larger. COHERS is both an implementation program and a research platform. In Rwanda, a randomized control trial is testing different intervention packages: human treatment only, pig vaccination only, hygiene-only, combined approaches, and control groups.
Every household visit, every latrine built, every pig vaccinated contributes to the data that will shape policy and future investment. In Senegal, similar studies are underway to assess the sustainability and cost-effectiveness of OHTs and other interventions.
Louise may not describe it this way, but her work—observing, advising, and reporting back—forms part of the evidence base that could help scale this model across Africa.
Working Together for Healthier Communities
What Louise values most about the OHT is the collaboration—working alongside peers in health, hygiene, water and sanitation. “Working together really works,” she says with a smile. By combining her household visits with community meetings and CHC activities, she sees families adopting new practices—building pig pens, washing hands, and sharing workloads at home. For Louise, each small change adds up to something bigger.
“We can protect ourselves from Taenia—and when we do, we protect our whole community. That’s what keeps me going.”

COHERS is a four-year initiative (2023–2027) that strengthens community health systems to prevent zoonotic diseases in Rwanda and Senegal by uniting human, animal, and environmental health. Funded by Global Affairs Canada and led by VWB, COHERS is delivered with local and international partners including the University of Global Health Equity, WaterAid Rwanda, the University of Guelph, the Institute of Health Economics, and Agronomes et Vétérinaires Sans Frontières.
