Malaria

 Transmitted to humans by female Anopheles mosquitoes carrying Plasmodium parasites, malaria is a possibly lethal disease. Among the most often occurring and deadly species invading people are Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. Once within the body, the parasites proliferate in the liver and then infect red blood cells, causing symptoms including high fever, chills, headaches, nausea, and sweating. Severe forms of malaria can cause anaemia, convulsions, coma, and sometimes death.

Particularly in sub-Saharan Africa, Asia, and sections of South America, the disease is most common in tropical and subtropical climates. Especially vulnerable are children under five, expectant mothers, and anyone with compromised immune systems. Recovery depends on early diagnosis made possible by blood testing and fast treatment with antimalarial medications such as artemisinin-based combination treatments (ACTs).
Using insecticide-treated bed nets, applying mosquito repellents, dressing in protective gear, and doing indoor insecticide spraying constitute part of preventive actions. Some places advise travellers to carry preventive antimalarial drugs. Through immunization, education, and improved healthcare access, continuous worldwide initiatives seek to lower transmission and finally eradicate malaria. Despite challenges, recent years have seen notable progress in reducing malaria-related mortality.
