What is the definition or description of: malaria?

Parasitic disease : Malaria is a parasitic disease that involves high fevers, shaking chills, flu-like symptoms, and anemia. See: http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0001646/.

Agree and...: The word comes from italian "mala aria" (bad air), from the belief the disease was caused by unhealthy air in swampy districts. Spread by mosquitoes, the parasite enter the bloodstream & infect red blood cells causing high fever, shaking chills, sweats, vomiting, muscle pain, headache, anemia. First symptoms occur 10 days to 4 weeks post infection, symptoms occur in cycles of 48 to 72 hours.
