Be seen today
Seek urgent same-day medical assessment if you develop a fever, chills, sweating, or flu-like illness while in a malaria area or after returning from one.
Symptoms may appear months or occasionally longer after travel.
Tell the healthcare team immediately that you have travelled to an area where malaria occurs.
Mention the countries, regions, dates, and preventive medicine taken.
Do not wait for a routine appointment if malaria is possible.

Does any of this apply?
Book an appointment
Keep planned appointments and complete any repeat blood tests after treatment.
Seek earlier review if fever returns, symptoms are not improving, or you cannot keep the medicine down.
Every sign above is quoted from the sofidex article on Malaria. If you are not sure, err upward — it is always reasonable to be checked.
