January and August showed seasonal peaks in the number of cases reported. Almost all of the malaria cases reported in the U.S. were acquired overseas; most cases were imported from India.

Malaria is caused by a parasite transmitted by the bite of an infective female Anopheles mosquito.

Signs and symptoms include fever, headache, back pain, chills, increased sweating, muscle pain, nausea, vomiting, diarrhea, and cough. Untreated infections can progress to coma, kidney failure, respiratory distress, and death.

Clinicians are recommended to consult the CDC Guidelines for Treatment of Malaria and contact CDC's Malaria Hotline for case management advice.  

Travelers to areas with malaria transmission can prevent the disease by taking steps such as use of antimalarial drugs, insect repellent, insecticide-treated bed nets, and protective clothing.
