What type of malaria does Plasmodium ovale cause?

Malaria is an infection passed through the bite of an infected mosquito. Plasmodium ovale mainly affects red blood cells, which can produce episodes of fever, chills and muscle aches. The parasite has a liver stage that may become inactive and later reactivate, so symptoms can return after an earlier illness or after a period without symptoms. A blood test can help identify malaria parasites, but tell the clinician about recent travel and any previous malaria diagnosis.

Arrange prompt medical assessment if malaria is possible, especially after travel or residence in an area where it occurs. Diagnosis usually involves a blood test and treatment chosen for the parasite and its liver stage. Take prescribed medicine exactly as directed and tell the clinician about pregnancy, other medicines, allergies and previous antimalarial treatment. A travel health consultation can review prevention before a future trip; prevention medicine does not replace mosquito-bite protection.

Seek urgent medical care for fever after travel to a malaria area, or for worsening fever with confusion, faintness, breathing difficulty, repeated vomiting, severe weakness or inability to drink. Malaria can become serious even when symptoms begin mildly. Chills or muscle aches with fever deserve prompt assessment rather than waiting for symptoms to settle at home.

Ask which test will confirm the parasite, whether repeat testing is needed if the first result is negative, and how recurrence from the liver stage will be addressed. Ask when it is safe to return to normal activities and what mosquito precautions apply.
