When she was a baby, Rehema was infected with malaria, but because her parents were able to get treatment for her, she survived. In the book, Rehema describes what children in the United States can do to help fight malaria. One little bite from one mosquito doesn't seem like a big thing, but if that mosquito carries the parasite that causes malaria, its bite can be very serious. Malaria is one of the most common infectious diseases, and it can be deadly. Each year, one million people die of malaria-that's one death every 30 seconds. In Africa, 75 percent of the malaria victims are children. Prevention is not only possible, but it's simple.
