Screening of Returnees from Malaria-Endemic Countries
Sri Lanka remains free of indigenous malaria since 2012, but the risk of re-introduction continues through travellers returning from endemic regions. The Anti-Malaria Campaign (AMC) conducts systematic screening to identify and treat imported malaria cases early, preventing onward transmission.
Who Should Be Screened
- Sri Lankan citizens returning from malaria-endemic countries (Africa, South Asia, Southeast Asia, etc.) (Country List- Link)
- Foreign workers, pilgrims, military personnel, and tourists arriving from endemic regions
- Travellers with fever or flu-like symptoms within one year of return
Screening Process
- Blood smear and/or Rapid Diagnostic Test (RDT) conducted by trained Public Health Laboratory Technicians (PHLTs) or Public Health Field Officers (PHFOs).
- Filter paper samples collected for molecular confirmation where microscopy is not immediately available.
- Screening initiated within 24 hours of notification and repeated after 3–4 weeks if indicated (secondary screening).
Why It Matters
Every imported malaria case poses a risk of re-establishing local transmission, especially in areas where Anopheles mosquito vectors still exist.
Early detection protects individuals and communities while sustaining Sri Lanka’s malaria-free status.
