Fever after travel to a malaria-endemic region.
Initial imported-fever triage when smear or rapid test access may be delayed.
Risk framing before urgent malaria testing and repeat smears.
Recent travel to endemic area
Rigors, cyclical fevers, or night sweats
Poor chemoprophylaxis adherence
Splenomegaly, thrombocytopenia, or hemolysis clues
Sub-Saharan Africa travel increasing falciparum concern
Order urgent malaria testing when pre-test probability is moderate or high.
Repeat smear testing if initial results are negative but suspicion remains high.
Escalate immediately when severe-malaria features coexist.
