Global Malaria Surge Triggers WHO Warning as Drug Resistance Accelerates

A Dangerous Resurgence After Years of Progress

The World Health Organization’s latest World Malaria Report 2025 reveals that the disease made a strong global comeback last year, driven by rapidly spreading drug resistance, strained health systems, and widening financial shortfalls. According to the report, an estimated 282 million people fell ill with malaria in 2024—nine million more cases than the year before.

The disease claimed about 610,000 lives, with young children once again suffering the heaviest toll. WHO officials warn that interconnected pressures—from climate-related shifts in mosquito habitats to prolonged conflict and humanitarian crises—are eroding the gains achieved since the early 2000s.

Africa and South Asia Shoulder the Heaviest Burden

The global spike was uneven, with the African continent absorbing the vast majority of the impact. WHO data shows that 94% of global infections and 95% of malaria deaths occurred in the African Region. Children under the age of five remain the most vulnerable group.

South Asia also recorded a sharp increase. India continues to carry the region’s largest malaria caseload, accounting for over 73% of infections and nearly 89% of deaths in the WHO South-East Asia Region in 2024.
While India has achieved notable reductions over the past decade, the report points to fresh challenges—dense urbanisation, climate-driven mosquito behaviour changes, and inconsistent access to high-quality prevention tools in rural belts.

New Tools Show Promise—but Not Enough to Reverse Trends

The WHO highlights that emerging technologies have helped blunt the disease’s impact. The rollout of malaria vaccines, upgraded insecticide-treated nets, and preventive therapies collectively prevented around 170 million cases and more than one million deaths in 2024.

As of early 2025, 24 countries had incorporated WHO-recommended malaria vaccines into routine immunisation. Long-term successes also continued: 47 countries and one territory have now been certified malaria-free, including Egypt and Timor-Leste in 2025.

Still, the WHO warns these gains are being overshadowed by stagnation at the global level. Since 2015, overall progress has slowed, putting 2030 global malaria reduction targets increasingly out of reach.

Why Malaria Is Rising Again: The Key Drivers

1. Drug Resistance Threatens Frontline Treatments

The report calls drug resistance one of the most urgent concerns. Artemisinin-based combination therapies (ACTs)—the world’s primary treatment for malaria—are losing potency in multiple regions. Eight countries have reported confirmed or suspected resistance, posing a direct threat to global treatment strategies.

2. Mosquito Resistance to Insecticides

Mosquito populations are evolving resistance to commonly used insecticides in nets and indoor sprays. This undermines some of the most cost-effective prevention tools ever deployed in public health.

3. Funding Gap Worsens

Global malaria funding reached only $3.9 billion in 2024—far below the $9.3 billion needed by 2025. A 21% drop in donor contributions has hit surveillance, community programs, and drug distribution, particularly in countries already struggling with fragile health systems.

4. Climate Change and Population Shifts Expand Mosquito Habitats

Rising temperatures, flooding, and irregular rainfall patterns are allowing mosquitoes to thrive in new regions. Rapid population growth in high-risk zones adds further pressure on public health systems.

Compounding these challenges is the spread of Anopheles stephensi—a mosquito species previously limited to parts of Asia and the Middle East. It has now been detected in nine African countries, increasing malaria risks in urban centres traditionally considered lower-risk.

Experts Warn: Global Momentum Is Slipping

WHO Director-General Dr. Tedros Adhanom Ghebreyesus said the latest figures underline a troubling pattern. While paraphrasing his remarks, the report notes that he highlighted rising cases, growing drug resistance, and shrinking funding as “major threats” to malaria control. Still, he stressed that these challenges can be overcome with stronger leadership in affected regions and sustained investment from international partners.

Dr. Martin Fitchet, CEO of Medicines for Malaria Venture, said the world must “move faster” to keep pace with evolving strains of the parasite, calling for aggressive investment in next-generation drugs and early-warning surveillance systems.

WHO Calls for Immediate, Coordinated Action

The WHO’s recommendations include:

• Accelerating investment in new vaccines, more durable insecticides, and advanced diagnostic tools

• Strengthening surveillance systems to detect drug-resistant malaria early

• Ensuring stable funding for prevention, treatment, and community health networks

• Building multi-sector coalitions across governments, research organisations, pharmaceutical companies, and community groups

Public health experts emphasise that malaria control can no longer rely solely on traditional health infrastructure. Coordinated, cross-sector action is essential to rebuild momentum and prevent further backsliding.
