Fever Testing

Direct answer: Fever is a syndromic presentation shared by dengue, malaria, influenza, COVID-19, typhoid and chikungunya. The right test depends on geography, exposure history and symptom timing.

Recommended biomarkers

Dengue NS1 (early) / IgM-IgG (later)
Malaria Pf HRP2 / Pan pLDH
Influenza A+B antigen
SARS-CoV-2 antigen
Typhoid IgG/IgM
Chikungunya IgG/IgM

Diagnostic workflow

Travel/exposure history → select pathogen tests → rapid antigen/serology → confirm by PCR or microscopy where needed.

Confirmatory testing

PCR (dengue, COVID, influenza), microscopy (malaria), culture (typhoid).
