Approximately half of the world's population is at risk of malaria. Specific population risk groups include:

  • young children living in malaria areas who have not yet developed protective immunity against the most severe forms of the disease. 
  • pregnant women, as malaria causes high rates of miscarriage and can lead to maternal death. 
  • 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.
