Who is at risk?

Approximately half of the world's population is 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 affected. In 2013, 97 countries and territories had ongoing malaria transmission.

Malaria Map

Specific population risk groups include:

young children in stable transmission areas who have not yet developed protective immunity against the most severe forms of the disease;
non-immune pregnant women as malaria causes high rates of miscarriage and can lead to maternal death;
semi-immune pregnant women in areas of high transmission. Malaria can result in miscarriage and low birth weight, especially during first and second pregnancies;
semi-immune HIV-infected pregnant women in stable transmission areas, during all pregnancies. Women with malaria infection of the placenta also have a higher risk of passing HIV infection to their newborns;
people with HIV/AIDS;
international travellers from non-endemic areas because they lack immunity;
immigrants from endemic areas and their children living in non-endemic areas and returning to their home countries to visit friends and relatives are similarly at risk because of waning or absent immunity
