Martin Fitchet, Dr.

Every year, World Mosquito Day brings renewed attention to mosquito-borne diseases like malaria. But attention is not enough. What matters now is whether we are using the tools we have effectively and whether those tools will still work tomorrow. Malaria drug resistance is not new. Until the early 2000s, chloroquine was the backbone of treatment. It was widely available and highly effective until resistance spread and treatments began to fail. Health systems were caught off guard, deaths rose, and the world learned a painful lesson: once resistance takes hold, recovery is slow, costly, and measured in lives lost. Today, we are seeing warning signs again. Resistance to existing first-line drugs is emerging in parts of East Africa, the Horn of Africa, Southeast Asia, and South America. At the same time, malaria deaths rose to 610,000 in 2024, up from 597,000 the year before, a trend unfolding against a backdrop of severe financing shortfalls. Global funding reached only $3.9 billion in 2024, less than half the $9.3 billion required. Sustained underinvestment has well-documented consequences: fewer preventive measures, overstretched health systems, and reduced capacity to respond when resistance emerges. The economic case for doing more is equally stark. According to a recently published analysis, reducing malaria cases by 90 percent by 2030 could increase Africa's GDP by $126 billion and expand global trade by $80.7 billion. Now urgency matters more than ever. We cannot afford to wait for existing tools to fail before acting. In the words of Dr. Brenda Akia, Africa representative and Vice Chair of the Committee on the United Nations Convention on the Elimination of All Forms of Discrimination against Women: "Malaria was killing people even when the drugs were working. Now that the drugs are failing, we are cooked if we do not act fast." Cooked, mingled and served as gourmet food at the bouquet where the mosquitoes will gather to celebrate their victory over humanity. This is not an exaggeration. The impact of chloroquine resistance—the memories of the increasing death tolls, the desperation to save lives with a tool that was becoming blunt— still lingers on. The response must be twofold. We need sustained financial commitment to ensure countries can procure and deliver existing tools through their health systems, and we need investment in new tools to stay ahead of resistance. Both are essential, and neither is optional. On the innovation front, there is encouraging progress. New medicines are advancing through development to better protect those most at risk. Through the work of Medicines for Malaria Venture and its partners, triple combination therapies designed to preserve the effectiveness of existing drugs are in development. In addition, ganaplacide-lumefantrine, a novel combination therapy developed with Novartis, has completed a Phase 3 trial with positive results. Looking ahead, long-acting injectable medicines that could provide protection against malaria for up to six months are also in development. Beyond new medicines, innovations in vector control are further strengthening the fight against malaria. These include new spatial emanator repellents that can provide protection for up to 12 months and dual-insecticide nets designed to combat insecticide resistance. Together, these advances reinforce our belief that ending malaria within a generation is within reach.However, as Brazil's Minister of Health Alexandra Padilha said recently, "Innovations that are not in the hands of those who need them are no good." As was done for the COVID-19 response, we must accelerate regulatory processes for innovations. Mechanisms must be put in place to make these critical innovations affordable and accessible. The health workforce must also be trained to deploy them effectively, and civil society organizations and community groups must also lead the way in raising awareness of the threat posed by drug resistance and the need for new tools. Countries are already showing leadership. For example, Thailand is strengthening its national strategy with a focus on surveillance and resistance response. Kenya is deepening community engagement. Rwanda is investing in stronger data systems. Uganda is supporting local manufacturing. These are concrete actions, not intentions. Countries have the capacity, but they need sustained and predictable financing to deliver new tools effectively. This is the moment for malaria elimination. Progress will not be secured by innovation alone, nor by financing alone, but by aligning both with strong country delivery systems. We call on the entire global health ecosystem to unite under one final “Big Push.” It is time to turn hope into well-funded action and finally take us across the finish line to a malaria-free world.
