Number of staff on phone surveillance at Occupational Health Clinic (OHC) before and after implementation of additional public health measures in hospital on 7 February 2020. All staff with unprotected exposure to COVID‐19 cases in the community or in the hospital and staff returning from overseas post‐travel would be put on phone surveillance of acute respiratory illness (ARI) symptoms twice a day. If they were asymptomatic at the end of 14‐day period post‐exposure or post‐travel, they would be able to return to work without further review. However, if they reported development of ARI symptoms when under surveillance, they would be required to report sick immediately and to be swab tested for COVID‐19. Altogether, a total of 376 staff were put on symptom surveillance in the first 3 months of COVID‐19 local transmission
