Meet Geneviève

“I used to stay up all night chasing away mosquitoes,” says Geneviève Ndagijimana, a 34-year-old mother from Burundi. “But it seemed like whatever I did, my children and I would get sick.”

Geneviève and her husband live in the suburbs of Bujumbura with their four children and two nephews. As far back as they can remember, they’ve lived in fear of getting malaria. They’ve lost many family members to the disease. “For many years, I suffered from countless cases of malaria, and I lost two children and my brother to the illness. That was a horrible period in my life.”

When she was pregnant with her fifth child, Geneviève was sure she would lose that baby, too. So, she went to a nearby health center to see if they could help.


PSI works to improve the availability, affordability and use of effective malaria prevention, diagnosis and treatment.

Nearly half the world’s population is at risk of malaria. Using case management, case identification, and prevention through insecticide-treated nets and drug-based methods, we aim to change that reality.

Here are some milestones we've achieved in the fight against malaria:

We've saved lives from malaria in

41 countries

We've distributed almost

400 million

insecticide-treated nets since 1997, about 20% of the global insecticide-treated nets distributed to date

Across our malaria interventions, we have provided

108 million years

of healthy life

From 2017 to 2018, we distributed

4 million

courses of seasonal malaria chemoprevention

We've distributed more than

151 million

pre-packaged malaria treatments

We've distributed more than

60 million

malaria rapid diagnostic tests since 2003

Our Malaria-Fighting Solutions

We support national governments to implement the most efficient vector control strategy for their population to reach universal preventative coverage against malaria. The two primary vector control activities we support are indoor residual spraying of homes with insecticides and increasing efficient coverage and proper use insecticide-treated nets. We use data and research to routinely analyze and improve our delivery of indoor residual spraying and insecticide-treated net interventions.

We work to ensure high-risk and hard-to-reach populations have access to diagnostic and treatment services. We support the training of providers to establish and follow clinical procedures to properly identify and address malaria cases. We ensure providers are equipped with the proper tools and medicines to effectively manage malaria with rapid diagnostic tests (RDTs) and treat it with artemisinin-based combination therapies (ACTs).

We work to develop effective surveillance tools to capture malaria information in a timely, complete manner in readily accessible tracking systems that are developed with user-centered design. We ensure these tools are available to public and private sector decision makers to target preventative and management approaches across the malaria transmission spectrum.

 Pushing the envelope to unlock the potential of proven key drug-based prevention approaches.

We target two of the most vulnerable populations—pregnant women and children under 5—using seasonal malaria chemoprevention for children and intermittent preventative treatment for pregnant women.
