Malaria Remains Endemic in 83 Countries: WHO Urges Renewed Global Action

April 29, 2025 – On World Malaria Day, the World Health Organization (WHO) has sounded a clarion call for renewed global commitment to eliminate malaria, a disease that continues to threaten millions worldwide. Despite significant progress over the past two decades, malaria remains endemic in 83 countries, underscoring the need for sustained vigilance and innovation.

Progress and Persistent Threats

As of April 2025, the WHO has certified 45 countries and one territory as malaria-free, marking a major milestone in the global fight against the disease. Encouragingly, 25 of the remaining malaria-endemic countries reported fewer than 10 cases in 2023, reflecting successful interventions and improved disease surveillance.

Since 2000, more than 2 billion cases of mosquito-transmitted malaria and nearly 13 million deaths have been prevented, according to WHO estimates. However, WHO Director-General Dr. Tedros Adhanom Ghebreyesus cautioned against complacency:

“The history of malaria teaches us a harsh lesson: when we divert our attention, the disease resurges, taking its greatest toll on the most vulnerable… But the same history also shows us what’s possible: with strong political commitment, sustained investment, multisectoral action, and community engagement, malaria can be defeated.”

Innovations Driving Hope

The WHO highlighted two major advancements fueling optimism in the fight against malaria:

1. Next-Generation Mosquito Nets:
   The deployment of new insecticide-treated nets-more effective than standard pyrethroid-only nets-has surged. In 2023, these advanced nets accounted for nearly 80% of all nets delivered in sub-Saharan Africa, up from 59% the previous year.

2. Malaria Vaccines:
   Two malaria vaccines, including Mosquirix and R21/Matrix-M, are now being administered in several African nations, such as Nigeria. These vaccines represent a critical tool in reducing disease transmission and protecting vulnerable populations.

Malaria in the United States

While malaria is not endemic in the United States, most cases are linked to travelers returning from Africa. States like Florida have reported cases among recent arrivals. Notably, the new malaria vaccines are not yet available in the U.S. For now, the Centers for Disease Control and Prevention (CDC) recommends travelers protect themselves by avoiding mosquito bites and taking prescribed antimalarial medications.

The Road Ahead

The WHO’s message is clear: the fight against malaria is far from over. Continued investment, innovation, and global cooperation are essential to prevent resurgence and ultimately eradicate this deadly disease.
