Kenya Met Warns of Looming Malaria Outbreak as Rains Raise Transmission Risk
The warning follows the release of the Malaria Epidemic Early Warning Prediction System for the Western Kenya Highlands, developed jointly by the Kenya Meteorological Department, the Ministry of Health Kenya, and the Kenya Medical Research Institute. The report projects elevated outbreak risks for April and May 2026, particularly in highland regions that are not traditionally prone to sustained malaria transmission.
“Malaria epidemic early prediction model outputs for the Western Highlands of Kenya indicate a high overall risk, including a 100% probability in Kisii, 60% in Nandi, and 27.3% in Kakamega during the forecast period,” the report states.
According to the projections, Kisii County faces the highest threat, with a 100 percent probability of an outbreak—far above the 20 percent epidemic threshold. Nandi County has also been classified as high risk, while Kakamega presents a moderate but notable risk slightly below the epidemic threshold.
Health experts attribute the heightened risk to above-average rainfall recorded in March, coupled with moderately warm temperatures that create ideal breeding conditions for mosquitoes. These environmental factors are known to accelerate the transmission cycle of Malaria.
High-burden regions remain concentrated around the Lake Victoria basin, including Kisumu, Siaya, Homa Bay, Migori, Busia, Vihiga, and Kakamega counties. These areas have historically recorded some of the highest malaria transmission rates in the country due to persistent climatic and environmental conditions.
Recent surveillance data indicates that some counties are reporting incidence rates as high as 748 cases per 1,000 people. While mortality rates have declined by 32 percent between 2019 and 2023, the disease continues to place a significant burden on Kenya’s healthcare system.
“The ongoing rains, combined with favourable temperatures, are expected to sustain mosquito breeding and increase transmission risks,” a health official noted.
Meteorologists attribute the current weather patterns to the northward movement of the Intertropical Convergence Zone (ITCZ), which is expected to bring widespread rainfall, occasional storms, and localized flooding. Daytime temperatures ranging between 20°C and 32°C are likely to further enhance mosquito activity.
Globally, malaria remains a major public health concern. According to the World Health Organization, an estimated 282 million cases and 610,000 deaths were recorded in 2024, underscoring the persistent threat posed by the disease.
In response to the warning, the government has urged residents, particularly in high-risk counties, to take preventive measures. These include eliminating stagnant water where mosquitoes breed, using insecticide-treated mosquito nets, and seeking early medical attention in case of symptoms.
“Communities must remain vigilant and take preventive steps to reduce exposure and protect vulnerable populations,” health authorities advised.
As the rainy season progresses, officials emphasize that coordinated efforts between government agencies, healthcare providers, and local communities will be critical in preventing a widespread outbreak.
The latest alert highlights the growing link between climate patterns and disease outbreaks, reinforcing the need for early warning systems and proactive public health interventions to mitigate risks and safeguard lives.
