From MOH report 6 March 2021:
a) Cases in the community: 1
There is 1 case in the community today who is currently unlinked.
Case 60666 is a 35 year-old female Indonesian national who is a foreign domestic worker. She arrived in Singapore on 20 January 2021 and served SHN at a dedicated facility until 3 February. Her swab done on 2 February during SHN was negative for COVID-19, as was her pre-departure test taken on 18 January while she was in Indonesia.
She is asymptomatic, and was detected when she took a COVID-19 pre-departure test on 4 March in preparation for her return to Indonesia. Her test result came back positive for COVID-19 infection, and she was conveyed to the National Centre for Infectious Diseases in an ambulance. Another test taken by the National Public Health Laboratory (NPHL) on 5 March came back negative for COVID-19 infection, and her serological test result has come back positive, which indicates a likely past infection. She is likely to be shedding minute fragments of the virus RNA, which are no longer transmissible and infective to others. However as we are unable to definitively confirm her date of infection, we will take all the necessary public health actions as a precautionary measure, including placing all her identified close contacts on quarantine.
