In 2001, I traveled to Ghana as a graduate student working on a US Agency for International Development-funded decentralization program. I arrived armed with materials on local governance best practices. But the mayors I met were focused on urgent public health issues: clean water, HIV/AIDS, tuberculosis, and malaria. That trip, meant to be an early lesson in governance, became my first and most personal education in global health. It also nearly killed me. I was taking mefloquine weekly to prevent malaria. Toward the end of our stay, my partner and I set off to explore the country. Somewhere along the way, I developed what I believed to be giardia. That infection likely compromised the absorption of the mefloquine and left me dangerously vulnerable. One night in the village of Kokrobite, I woke with a high fever and chills so intense I could barely stand. A local man saw me and immediately recognized it as malaria. He arranged for a taxi to take me back to Accra. Before I left, he handed me a small, crumpled packet labeled in Chinese characters. Inside was a blister pack of pills. The only word written in English on the package was artesunate. He told me it would help, and, in that moment, sick, scared, and weak, I took it. At the hospital, a blood smear confirmed that I had cerebral malaria caused by Plasmodium falciparum, the deadliest strain. Cerebral malaria can cause brain swelling, coma, and death. I drifted in and out of consciousness for days. At one point, hospital staff told my partner that there was nothing more they could do. I should “go home” and be “as comfortable as possible.”My partner worked relentlessly to get me on one of the next flights back to the United States. I was so sick that the airline nearly refused to let me board. Once we arrived home, I was seen right away by an infectious disease doctor at Johns Hopkins Hospital. After reviewing my labs and the herbal remedy package, he said plainly: this saved your life. The artesunate had bought me enough time to survive the journey and begin treatment. At the time, the World Health Organization had not yet formally endorsed artemisinin-based combination therapies (ACTs) as the global standard for P. falciparum malaria. That came in 2006. But the effectiveness of artesunate alone was already well known in many parts of the world. That medicine saved my life.I missed several weeks of school but made a full recovery. Without that drug and the help of my partner (now my husband) and friends in Accra, I wouldn’t be here today. More than two decades have passed, and we've made tremendous progress. Insecticide-treated bed nets, rapid diagnostic tests, and ACTs have saved millions of lives. Two malaria vaccines, RTS,S and R21/Matrix-M, have been approved. Long-acting monoclonal antibodies are showing promise as seasonal protection for children. Newer insecticide-treated nets help counter resistance. And researchers are exploring RNA-based therapeutics and single-dose cures.Many of these breakthroughs are being developed by members of the Global Health Technologies Coalition, where I now serve as Executive Director. These tools represent our best chance not just to control malaria but to end it.But progress is not guaranteed. Cuts to foreign assistance and global health research and development are already slowing the progress of innovations in the pipeline. Some promising tools may be delayed or abandoned. That means more children at risk, more untreated infections, and more drug-resistant strains emerging. The parasite has evolved before. It will do so again if we let it. And malaria is no longer a disease that happens mostly outside of the United States. In the past two years, locally acquired cases have been reported in Florida, Texas, and Maryland. Climate change, global travel, and changing mosquito habitats are making malaria a threat we can no longer treat as distant. I know how thin the line is between surviving this disease and not. For me, it’s not abstract. It’s the memory of a fevered body, the generosity of strangers, and a medicine in the right place at the right time. This World Malaria Day, I urge leaders and policymakers to stay the course. The science is moving forward. But science alone isn’t enough. If we don’t finish what we’ve started, we risk letting malaria surge back and take more lives with it. Science has given us the tools. The question now is whether we will act in time or let the disease outpace us once again.
