Singapore will add Crimean-Congo haemorrhagic fever, Lassa fever and Marburg virus disease to the list of legally notifiable infections from 31 October 2026, requiring doctors and clinical laboratories to report suspected and confirmed cases to the Communicable Diseases Agency.
What changes on 31 October
Parliament amended the Infectious Diseases Act and regulations in September. The move expands the Second Schedule of dangerous infectious diseases from five to eight entries, joining Ebola, MERS, plague, SARS and yellow fever.
Medical practitioners must notify CDA of all suspected and confirmed cases. Laboratories must do the same for positive results. Notifications enable isolation, contact tracing and port-of-entry screening if risk profiles change.
Clinical stakes
World Health Organization materials cite fatality rates up to about 50 percent for these viral haemorrhagic fevers. No approved vaccines or antivirals are widely available, though vaccine candidates for Lassa and Marburg are in development pipelines.
A CDA spokeswoman told The Straits Times the absolute risk to Singapore remains low, but formal listing ensures early detection and a rehearsed response if a traveller presents with compatible symptoms.
Border measures already in place
Electronic Health Declaration cards require inbound travellers to declare health status and recent travel. Medical assessment remains available at checkpoints for symptomatic passengers from affected regions.
Weekly CDA surveillance bulletins will include the three diseases from November, giving epidemiologists a published baseline even when case counts are zero.
What patients might notice
Most residents will not see day-to-day changes unless an alert is triggered. Clinicians receive updated notification forms and laboratory codes. Hospitals maintain isolation protocols practised during prior coronavirus and Ebola scares.
Travellers to endemic regions should continue insect-bite prevention for Crimean-Congo fever and avoid contact with rodent excreta in Lassa-endemic areas. Marburg risk historically clusters around bat-linked exposures in Africa.
Why list now
Global outbreak monitoring has improved after COVID-19. Listing fevers with epidemic potential lets Singapore activate the same legal tools used for SARS without waiting for a crisis. CDA said it periodically reviews the schedule to keep pace with WHO notifications.
Clinic workflow
Primary-care doctors receive automated updates in the MOH notification system when schedules change. Suspected cases trigger phone reporting to CDA operations centres; laboratories upload polymerase chain reaction results through the same channel used for dengue and COVID-19 during peak seasons.
Public hospitals maintain negative-pressure rooms rehearsed during Ebola preparedness drills. While no local cases are expected imminently, the legal listing ensures isolation orders and contact quarantine powers are available without emergency legislation.
Employers should refresh travel health memos for staff visiting sub-Saharan Africa or the Middle East, regions where sporadic Marburg or Crimean-Congo clusters have appeared in WHO outbreak reports. Insurance policies vary on evacuation coverage for viral haemorrhagic fevers; human resources teams should cite official MOH travel notices rather than social media rumours.
