QUESTION

How many countries are malaria infected?

ANSWER

As of 2010, there were 108 countries which were listed as having endemic malaria—that is, malaria which was transmitted within the country. This includes 43 countries in Africa, 10 countries in south-east Asia, 13 countries in the Eastern Mediterranean (which includes most of Central Asia and parts of North and East Africa—90% of the malaria burden in this region is suffered by Sudan, Afghanistan, Pakistan and Somalia), 10 countries in the Western Pacific (though this region constitutes less than 1% of global malaria cases) and 23 malaria-endemic countries in the Americas.
