Malaria is a disease of the blood that is caused by the Plasmodium parasite, which is transmitted from person to person by a particular type of mosquito called the anopheles mosquito.
In 2015, approximately 3.2 billion people – nearly half of the world's population – were at risk of malaria. Most malaria cases and deaths occur in sub-Saharan Africa. However, Asia, Latin America, and, to a lesser extent the Middle East and parts of Europe, are also at risk. In 2015, 97 countries and territories had ongoing malaria transmission.
Prevention is always better than cure. And malaria is an incurable disease hence mainly involves protecting yourself against mosquito bites and taking antimalarial medicines.
