What should you know about four types of malaria?

Plasmodium falciparum can progress quickly and is associated with severe disease. P. vivax and P. ovale can remain dormant in the liver and return later without further mosquito exposure. P. malariae may persist for a long time and can cause recurring fever. These labels are not determined reliably from symptoms alone; laboratory testing identifies the parasite and guides treatment. Fever, chills and muscle aches are common features, but some people initially have less typical symptoms.

Get medical advice promptly for fever or chills during travel or after returning from a malaria area. Tell the clinician where you travelled, when you returned, and whether you took prevention medicine. A blood test may need repeating if early results do not explain symptoms. Take prescribed treatment exactly as directed. Before future travel, a travel health consultation can match malaria prophylaxis and bite prevention to the destination and your health.

Seek emergency care for confusion, fainting, seizures, breathing difficulty, severe weakness, yellowing of the skin, very dark urine, or inability to drink. Malaria can become serious quickly, particularly when falciparum infection is possible. Do not wait for a fever pattern to become obvious before seeking assessment.

Ask which parasite may be involved, whether repeat blood testing is needed, how long treatment lasts, what recurrence could look like, and which prevention plan suits your next trip.
