Fever after travel: when to worry

2 min readRed flags
When to use

Any fever within 12 months of returning from a malaria-risk area — especially in the first 3 months.

See a doctor urgently if you have
  • Fever within 3 months of leaving a malaria area — get a malaria test the same day.
  • Fever with confusion, breathlessness, a stiff neck, or a spreading rash.
  • Yellow eyes/skin, very dark urine, or persistent vomiting.
Tell the doctor
  • Exactly where you travelled and when you got back.
  • Whether you took malaria prevention — and if you finished it.
  • Any freshwater swimming, animal contact, or insect bites.
Key point
  • Malaria can appear weeks after travel and is rapidly treatable — but deadly if missed. Don't 'wait it out'.
