Fever in Returning Traveller Assessment

Stratifies risk and guides urgent investigation in febrile returning travellers. Malaria must be excluded in all cases.

Score interpretation

Low urgency — standard investigation

→ FBC, malaria blood film x3 (even if prophylaxis taken), LFTs, urine dip; common diagnoses: viral illness, UTI, enteric fever; safety net to return if deteriorates

Moderate risk — urgent investigation

→ Same-day malaria film + RDT; FBC, CMP, LFTs, blood cultures; HIV test; typhoid serology; dengue NS1/IgM; ID team review; admit if uncertain diagnosis

High risk — emergency malaria/tropical fever

→ Immediate thick and thin blood film + RDT; IV access; resuscitation if shocked; empirical IV artesunate if high malaria suspicion and severely unwell; ID team immediately; consider VHF (Ebola, Lassa) if haemorrhage + HDE; isolate if VHF suspected
