Viruses- Malaria

Malaria is a disease transmitted by an infected female Anopheles mosquito. Malaria is transmitted in humans  through the bite of the mosquito. When a mosquito bites an infected person, a small amount of blood that contains the microscopic malaria parasites is taken, a week later when the mosquito has its next blood meal, the malaria parasites mix with the mosquito's saliva and is injected into the human that is bitten.

The symptoms of malaria are flu-like symptoms.This includes chills, headaches, muscle aches, tiredness, nausea, vomiting and diarreah. Malaria can also cause anemia and jaundice because of the loss of red blood cells. The symptoms begin 10 to 4 weeks after being bitten.

90% of malaria cases are from the tropics and sub-Saharan Africa and 10% of the cases are from India,Brazil, Afhganistan, Sri Lanka, Thailand, Indonesia, Vietnam, Cambodia, and China.
