Malaria is a life-threatening disease caused by parasites that are transmitted to humans through the bite of infected female Anopheles mosquitoes.

In Kenya, the disease is endemic, with an estimated 70% of the population at risk of infection.

 Climate change has a significant impact on the spread of malaria in Kenya.

Rising temperatures and changing rainfall patterns create ideal breeding conditions for mosquitoes, which thrive in warm, humid environments.

As a result, the number of malaria cases is increasing, particularly in areas that were previously considered low-risk.

One of the ways that climate change is affecting malaria transmission in Kenya is by altering the seasonal patterns of rainfall.

In some areas, rainfall is becoming more erratic, with longer dry spells followed by heavy downpours.

This creates ideal breeding conditions for mosquitoes, as stagnant water accumulates in puddles and other areas. 

Rising temperatures catalyze mosquito maturity, leading frequent breeding cycles thus increased transmission.

 As temperatures rise, mosquitoes adopt survival at higher elevations and in areas that were previously too cold for them to thrive. This means that populations that were previously considered low-risk are now at greater risk of infection.

 The impact of climate change on malaria in Kenya is a serious concern for to public health.

Efforts to control the spread of the disease must take into account the changing environmental conditions that contributes to its transmission.

This may include measures such as mosquito control programs, improved access to healthcare, medications, and public education campaigns to raise awareness about the risks of malaria and how to prevent infection.
