A blood disease spread by mosquitoes that can be fatal is malaria. Humans are exposed to the parasite plasmodium by the Anopheles mosquito. The symptoms of malaria caused by these parasites include fever, chills, headaches, sweating, weakness, and other symptoms. Later, a serious illness could emerge with multisystem failure, severe anemia, renal failure, and an abnormal level of consciousness. This book discusses more about the signs, causes, and treatment for malaria.
