Climatic studies

These studies help monitor climatic factors that can influence both the mosquito vector and the malaria parasite’s development, and to assess changes in malaria transmission in relation to interventions and other factors as well as the impact of climatic trends.

How are the climatic studies conducted?

Automated weather stations are installed in the compounds of each of the study site health centres. These collect climatic data on temperature, humidity and rainfall. The data is downloaded regularly and used to see how climate influences incidence rates in the study sites.

What data is collected during climatic studies?

  • Temperature
  • Relative humidity
  • Rainfall

Why is the climatic studies data important?

  • The variables measured in these studies are the three main climatic conditions which can affect malaria transmission rates.
    • Rainfall affects the breeding of mosquitoes
    • Humidity affects the longevity of mosquitoes
    • Temperature influences the cycle of the malaria parasite, duration of development of the aquatic stages of the mosquito and survival of the adult mosquito.

These studies can be an important surveillance tool, especially in the study sites that are prone to epidemics. In addition, the other factors influencing malaria transmission can be studied in the context of climatic trends.
