Currently, cases of human malaria are mainly found in Central and South America, parts of the Caribbean, sub-Saharan Africa, parts of the Middle East, south Asia, south-east Asia, and the Pacific Islands of Oceania. Control efforts, mainly consisting of reducing populations of vector mosquitoes, has eliminated transmission from North America, most of Europe, most of North Africa and parts of the Middle east and Asia.

QUESTION

Where is malaria found?

ANSWER

Malaria is found throughout the world’s tropical and sub-tropical areas, and mainly in Central and South America, Africa, Asia and the Indo-Pacific region. It is most common in tropical regions, where transmission occurs year-round; in sub-tropical and temperate areas, transmission may only occur during seasons that have appropriate climatic conditions. This includes sufficiently high temperature and water availability for the growth and development of the mosquito, which transmits the disease.
