Control of Severe Acute Respiratory Syndrome in Singapore

Abstract

A Severe Acute Respiratory Syndrome (SARS) outbreak occurred in Singapore from February to May 2003. A high vigilance for the disease, frequent and regular temperature monitoring, early case identification and isolation of patients, as well as tracing and home quarantine of contacts, played major roles in controlling the outbreak. Hospitals were dedicated to the screening and treatment of SARS patients. Within and between hospitals, movement by healthcare workers, patients and visitors were restricted, as was the number of hospital visitors. Staff education and audits of infection control practices also featured prominently.
To prevent cross-border transmission, incoming travellers from SARS affected areas had to complete health declaration cards. They, as well as all outgoing travellers from Singapore, were monitored for fever. In the meantime, the public was urged to refrain from travelling to SARS affected regions.
Containment elements targeting the community included school closure, public education on good hygiene and readily accessible public information.
In response to a laboratory acquired SARS infection, laboratories were audited, and directives issued on the mandatory use of biosafety level 3 laboratories for SARS virus culture, and compliance of laboratory workers to biosafety guidelines.
