Each year, 263 million people get malaria. But from the parasite's perspective, infecting humans is harder than you might think, and requires completing an epic journey within the tiny body of a mosquito. First, the mosquito must suck the blood of an individual infected with malaria — bringing the Plasmodium parasite into the insect's gut.
