Globally in 2022, there were an estimated 249 million malaria cases and 608 000 malaria deaths in 85 countries.The WHO African Region carries a disproportionately high share of the global malaria burden.In 2022, the Region was home to 94% of malaria cases (233 million) and 95% (580 000) of malaria deaths.Children under 5 accounted for about 80% of all malaria deaths in the Region.Malaria is a life-threatening disease spread to humans by some types of mosquitoes. It is mostly found in tropical countries. It is preventable and curable. The infection is caused by a parasite and does not spread from person to person. Symptoms can be mild or life-threatening. Mild symptoms are fever, chills and headache. Severe symptoms include ...
The most common early symptoms of malaria are fever, headache and chills. Symptoms usually start within 10–15 days of getting bitten by an infected mosquito. Symptoms may be mild for some people, especially for those who have had a malaria infection before. Because some malaria symptoms are not specific, getting tested early is important. Some type...
According to the latest World malaria report, there were 249 million cases of malaria in 2022 compared to 244 million cases in 2021. The estimated number of malaria deaths stood at 608 000 in 2022 compared to 610 000 in 2021. The WHO African Region continues to carry a disproportionately high share of the global malaria burden. In 2022 the Region w...
Malaria can be prevented by avoiding mosquito bites and by taking medicines. Talk to a doctor about taking medicines such as chemoprophylaxis before travelling to areas where malaria is common. Lower the risk of getting malaria by avoiding mosquito bites: 1. Use mosquito nets when sleeping in places where malaria is present 2. Use mosquito repellen...
Early diagnosis and treatment of malaria reduces disease, prevents deaths and contributes to reducing transmission. WHO recommends that all suspected cases of malaria be confirmed using parasite-based diagnostic testing(through either microscopy or a rapid diagnostic test). Malaria is a serious infection and always requires treatment with medicine....
Malaria elimination is defined as the interruption of local transmission of a specified malaria parasite species in a defined geographical area as a result of deliberate activities. Continued measures to prevent re-establishment of transmission are required. In 2022, 34 countries reported fewer than 1000 indigenous cases of the disease, up from jus...
Malaria surveillanceis the continuous and systematic collection, analysis and interpretation of malaria-related data, and the use of that data in the planning, implementation and evaluation of public health practice. Improved surveillance of malaria cases and deaths helps ministries of health determine which areas or population groups are most affe...
The WHO Global technical strategy for malaria 2016–2030, updated in 2021, provides a technical framework for all malaria-endemic countries. It is intended to guide and support regional and country programmes as they work towards malaria control and elimination. The strategy sets ambitious but achievable global targets, including: 1. reducing malari...
Malaria is a life-threatening disease caused by parasites of the genus Plasmodium, mostly transmitted by mosquitoes. Learn about the different types of malaria parasites, how to prevent and treat the infection, and the global burden of the disease.
Malaria is a mosquito-borne infectious disease that affects vertebrates. [6] [7] [3] Human malaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. [1] [8] In severe cases, it can cause jaundice, seizures, coma, or death.

Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria.
There are approximately 156 named species of Plasmodium which infect various species of vertebrates. Four species are considered true parasites of humans, as they utilize humans almost exclusively as a natural intermediate host: P. falciparum, P. vivax, P. ovale and P. malariae.
