2. Overall, the number of new cases in the community has increased from 4 cases in the week before to 10 cases in the past week. The number of unlinked cases in the community has also increased from 3 cases in the week before to 5 cases in the past week. We will continue to closely monitor these numbers, as well as the cases detected through our surveillance programme.
3. Amongst the 174 confirmed cases reported from 17 April to 23 April, 65 cases have tested positive for their serology tests, 73 have tested negative, and 36 serology test results are pending.
Case Detailsa) Cases in the community: 2There are 2 cases in the community today who are currently unlinked.
Case 62285Case 62285 is a 33 year-old male Indonesia national who is a sea crew on board a bunker tanker. He arrived by flight from Indonesia on 4 February and served SHN at a dedicated facility until 18 February. His on-arrival test on 4 February was negative for COVID-19, as was his test taken during SHN on 17 February. He boarded a vessel on 18 February, and had not disembarked except to go for COVID-19 vaccination.
He is asymptomatic, and was detected when he was tested onboard on 20 April as part of our protocol to test sea crew. His test result came back positive for COVID-19 the next day, and he was conveyed in an ambulance to the National Centre for Infectious Diseases (NCID). His serology test result has come back positive.
Case 62285 received his first dose of COVID-19 vaccination on 16 April. As the vaccine does not contain live virus, he could not have been infected due to vaccination. It is possible for one to be infected just before or just after vaccination as it typically takes a few weeks for an individual to build up immunity after completing vaccination.
Case 62294 Case 62294, a 38 year-old male Indonesia national, is a Short-Term Visit Pass holder who is in Singapore for a work project. He arrived from Indonesia on 28 March and served SHN at a dedicated facility until 11 April. His on-arrival test, as well as swab taken during SHN on 10 April, were negative for COVID-19.
He is asymptomatic, and was detected when he took a COVID-19 pre-departure test on 22 April in preparation for his trip back to Indonesia. His test result came back positive on the same day, and he was conveyed in an ambulance to Mount Elizabeth Hospital. His serology test result has come back positive. He received his first dose of COVID-19 vaccine on 4 March, and the second dose on 18 March in Indonesia.
b) Cases residing in dormitories: 1There is 1 case residing in a dormitory today who is currently unlinked.
Case 62273, a 21 year-old male India national, is a Work Permit holder who arrived in Singapore in October 2018. He is employed by Sembcorp Marine Integrated Yard Pte Ltd and works at Sembcorp Marine Tuas Boulevard Yard. He resides at SCM Tuas Lodge (80 Tuas South Boulevard).
He is asymptomatic, and was detected when he was tested on 19 April as part of Rostered Routine Testing (RRT). His pooled test result came back positive for COVID-19, and he was immediately isolated. An individual test was done on 20 April, and his test result came back positive for COVID-19 infection the next day. He was subsequently conveyed to NCID in an ambulance. His earlier tests from RRT – the last being on 12 April – were all negative for COVID-19 infection. His serology test result has come back positive.
Case 62273 received his first dose of COVID-19 vaccine on 11 March, and the second dose on 1 April. This likely accounts for his lack of symptoms and positive serology test result. The COVID-19 vaccine is effective in preventing symptomatic disease for the vast majority of those vaccinated, but it is possible for vaccinated individuals to get infected. Further research is required to determine if the vaccination will also prevent onward transmission of the infection. Our existing key enablers – safe management measures, testing, and contact tracing – continue to be necessary and effective in helping us to mitigate spread and keep community transmission low.

5. Epidemiological investigations are ongoing. In the meantime, all the identified close contacts of the cases have been isolated and placed on quarantine, and will be tested at the start and end of their quarantine period so that we can detect asymptomatic cases. We will also conduct serological tests for the close contacts to determine if the cases could have been infected by them.
