Malaria
Malaria is a life-threatening disease caused by parasites of the genus Plasmodium, which are transmitted to people through the bites of infected female Anopheles mosquitoes. There are five parasite species that cause malaria in humans, with Plasmodium falciparum and Plasmodium vivax being the most common and dangerous.
Causes and Transmission :
- Parasites : The five Plasmodium species are P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi.
- Transmission : When an infected Anopheles mosquito bites a person, the parasites are transferred from the mosquito's saliva into the person's bloodstream.
Diagnosis :
- Based on symptoms and travel history to endemic areas.
- Confirmed through laboratory tests, such as blood, stool, or urine cultures to detect Salmonella Typhi.
