Symptoms of Malaria usually occur within 7-30 days after being bitten, but can in rare cases take as long as a full year to develop. Symptoms include high fevers, shaking, chills, muscle aches and other flu-like symptoms, which can last for a long time if left untreated. Certain severe instances of the disease cause symptoms such as: anemia caused by the destruction of infected blood cells, extreme tiredness, delirium, unconsciousness, convulsions, kidney failure, pulmonary edema and even coma. With treatment the disease can be treated in 3-7 days, with full removal of the parasite.
