Climatic suitability for infectious disease transmission - Malaria
Description
Climatic conditions across Europe are becoming more suitable for emergence and transmission of climate‑sensitive infectious diseases. Malaria is a mosquito-borne disease caused by Plasmodium parasites and spread to humans via mosquitos. The disease was endemic in Europe until the 1970s, when it got eliminated. An increasing number of malaria cases is being registered in Europe, largely attributable to international travel. Together with the widespread presence of the malaria vector (Anopheles mosquitoes) and the increasing climatic suitability for this vector (increased rainfall and higher temperatures) in Europe, malaria may re‑emerge in the region.
Caveats
This indicator reflects the state of conditions that would potentially allow malaria transmission to occur, had there not been public health efforts to control it. In this regard, this is indicator should be interpreted in the context of the current efforts that are allowing Europe to keep malaria from returning to the continent.
