Number of malaria cases
Reported confirmed cases, 2013
48 271 264 confirmed malaria cases were reported in 2013, by 97 countries and territories with ongoing malaria transmission
Reported confirmed malaria cases represent cases identified in the health care system and reported through each country’s surveillance system. Due to incomplete attendance, diagnostic testing and reporting of cases, the number of reported cases is unlikely to represent the true number of cases, and is usually lower than the number of estimated cases, which takes these factors into account.
