Health authorities in Mombasa County have declared a Chikungunya outbreak following laboratory confirmation of multiple cases. Out of 45 samples sent to the Kenya Medical Research Institute (KEMRI), 25 tested positive for Chikungunya and one for Dengue Fever.
Chikungunya is a viral infection transmitted by the female Aedes mosquito, known to cause severe muscle, joint, and body pains that can cripple patients temporarily. The name “Chikungunya” is derived from a Makonde word describing the bent posture of those afflicted by the debilitating pain.
Dr. Victor Ofula, a senior researcher at KEMRI, noted that the Aedes mosquito primarily bites between 11 a.m. and 3 p.m., increasing the risk of daytime transmission. He explained that the mosquito’s eggs can survive in dry environments and hatch when exposed to water — a key factor in the virus’s persistence.
“The female Aedes mosquito can pass the virus to its eggs, which later hatch into infected mosquitoes. This allows the virus to spread even without human-to-human contact,” said Dr. Ofula.
Experts warn that changing climate patterns, particularly rising temperatures and increased rainfall, are creating ideal conditions for the breeding and survival of these mosquitoes, accelerating the risk of outbreaks in more regions. The Aedes mosquito is already present across the country, raising concerns about the spread of the virus through human travel from endemic areas such as Mombasa and Mandera.
County governments are now being urged to strengthen disease surveillance and public awareness campaigns to curb the spread of the infection. Preventive measures include eliminating mosquito breeding grounds, wearing protective clothing, and using insect repellents.
Health officials have emphasized the need for coordinated efforts to manage the outbreak and prevent its expansion to other parts of the country.
