Colossal. Used to describe a series of calamitous events that occur over a short period of time, that are either intrinsically linked, completely random, or fall somewhere in the middle. Joey: Dude you won't believe what has just fuckin' happened to me over the last week!
Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito.
The female Anopheles mosquito is the only mosquito that transmits malaria. She primarily bites between the hours of 9pm and 5am, which is why sleeping under a mosquito net at night is such an important method of prevention.
