The vaccine has been shown to significantly reduce malaria, and deadly severe malaria, among young children. Since October 2021, WHO also recommends broad use of the RTS,S/AS01 malaria vaccine among children living in regions with moderate to high P. ![]() These safe and cost-effective strategies are intended to complement ongoing malaria control activities, including vector control measures, prompt diagnosis of suspected malaria, and treatment of confirmed cases with antimalarial medicines. Preventive chemotherapy includes perennial malaria chemoprevention (PMC), seasonal malaria chemoprevention (SMC), intermittent preventive treatment of malaria in pregnancy (IPTp) and school-aged children (IPTsc), post-discharge malaria chemoprevention (PDMC) and mass drug administration (MDA). It requires giving a full treatment course of an antimalarial medicine to vulnerable populations (generally infants, children under 5 years of age and pregnant women) at designated time points during the period of greatest malarial risk, regardless of whether the recipients are infected with malaria. Preventive chemotherapy is the use of medicines, either alone or in combination, to prevent malaria infections and their consequences. As described in the latest World malaria report, other threats to ITNs include insufficient access, loss of nets due to the stresses of day-to-day life outpacing replacement, and changing behaviour of mosquitoes, which appear to be biting early before people go to bed and resting outdoors, thereby evading exposure to insecticides. Progress in global malaria control is threatened by emerging resistance to insecticides among Anopheles mosquitoes. The 2 core interventions are insecticide-treated nets (ITNs) and indoor residual spraying (IRS). Vector control is a vital component of malaria control and elimination strategies as it is highly effective in preventing infection and reducing disease transmission. Over the last 2 decades, expanded access to WHO-recommended malaria prevention tools and strategies – including effective vector control and the use of preventive antimalarial drugs – has had a major impact in reducing the global burden of this disease. Republic of Tanzania (4.1%) and Niger (3.9%). Nigeria (31.3%), the Democratic Republic of the Congo (12.6%), United Children under 5 years of age accounted forĪbout 80% of all malaria deaths in the Region.Ĭountries accounted for just over half of all malaria deaths worldwide: In 2021 the Region was home to about 95% of all malariaĬases and 96% of deaths. ![]() Region continues to carry a disproportionately high share of the global More malaria cases and 63 000 more malaria deaths. Pandemic (2020–2021), COVID-related disruptions led to about 13 million The estimated number of malaria deaths stood at 619 000 in Were 247 million cases of malaria in 2021 compared to 245 million cases ![]() Disease burdenĪccording to the latest World malaria report, there Some population groups are at considerably higher risk of contracting malaria and developing severe disease: infants, children under 5 years of age, pregnant women and patients with HIV/AIDS, as well as people with low immunity moving to areas with intense malaria transmission such as migrant workers, mobile populations and travellers. In 2021, nearly half of the world's population was at risk of malaria. falciparum malaria can progress to severe illness and death within a period of 24 hours. The first symptoms – fever, headache and chills – usually appear 10–15 days after the infective mosquito bite and may be mild and difficult to recognize as malaria. vivax is the dominant malaria parasite in most countries outside of sub-Saharan Africa. falciparum is the deadliest malaria parasite and the most prevalent on the African continent. There are 5 parasite species that cause malaria in humans, and 2 of these species – P. Malaria is an acute febrile illness caused by Plasmodium parasites, which are spread to people through the bites of infected female Anopheles mosquitoes. ![]()
