What are the first signs of malaria?

Malaria is caused by parasites transmitted through the bite of an infected mosquito. Early illness can feel like a flu-like infection, with fever, chills, sweating, headache, weakness, nausea or muscle aches. Symptoms may come in episodes, but they do not always follow a predictable pattern. The timing after travel can vary, and malaria can become serious quickly. Fever after visiting a malaria-risk area needs medical attention even if you took preventive medicine or returned some time ago.

Tell a clinician promptly about every country or region visited, the dates of travel, mosquito bites, preventive medicines and the start of symptoms. A Blood Test may be needed to look for malaria parasites, and repeat testing can sometimes be considered when symptoms continue. Do not rely on leftover medicines or wait for a typical fever pattern. Before future travel, a Travel Health Consultation can review prevention, and Malaria Prophylaxis may be suitable for some itineraries.

Get urgent medical help for fever after travel to a malaria-risk area, especially with confusion, fainting, breathing difficulty, repeated vomiting, severe weakness or yellowing of the skin or eyes. Emergency care is needed for seizures, collapse or reduced alertness. Mention possible malaria when contacting a service so testing can be arranged quickly.

Could my travel history fit malaria exposure? Do I need immediate testing or repeat testing? Which warning signs should bring me back urgently? What prevention would suit my next trip?
