Is malaria caused by a virus?

The malaria parasite enters the bloodstream and infects red blood cells. That is why malaria requires specific testing and treatment rather than routine care for a viral infection. Fever, [Chills](/symptoms/chills/), sweating, headache, and body aches may occur, but these features overlap with many illnesses.

A symptom cannot show which infection is present. Travel to a malaria-risk area, mosquito exposure, and the timing of illness help a clinician decide what to investigate. Learn more on [Malaria](/conditions/malaria/).

Write down your travel locations, return date, mosquito exposure, medicines, and the time symptoms began. Arrange prompt clinical assessment for fever after possible exposure. A [Blood Test](/treatments/diagnostics-and-screening/blood-test/) may be used to look for malaria, and repeat assessment may be needed if symptoms continue.

For future travel, discuss [Malaria Prophylaxis](/treatments/occupational-and-travel-medicine/malaria-prophylaxis/) and bite prevention before departure. Do not start leftover medicine without professional advice.

Seek urgent help if fever is accompanied by confusion, severe drowsiness, breathing difficulty, fainting, seizures, or repeated vomiting. Any unexplained fever after travel to a malaria-risk area deserves prompt medical attention, because the illness can become serious while initially resembling a viral fever.

Ask which tests distinguish malaria from viral illness, whether treatment should begin while results are pending, and which warning signs require emergency care. A [Travel Health Consultation](/treatments/occupational-and-travel-medicine/travel-health-consultation/) can address prevention for a planned trip.
