SINGAPORE — The Ministry of Health (MOH) on Tuesday (27 April) confirmed 12 new COVID-19 cases in Singapore, taking the country's total case count to 61,063.
One of them is a case of local transmission in the community, while the remaining 11 are imported. This marks the second day in a row with reported local cases.
"Amongst the new cases today, seven are asymptomatic, and were detected from our proactive screening and surveillance, while five were symptomatic," said the MOH.
The sole community case is the sixth case linked to the "Case 62113" cluster, named after the case number of a 39-year-old Indonesian man who is a sea crew member on board a bunker tanker.
The 42-year-old male compatriot is also a sea crew member working onboard bunker tanker MT ALLI.
The man had not disembarked from the vessel except to go for COVID-19 vaccination, receiving his first dose on 8 April, said the MOH.
"As it typically takes a few weeks for an individual to build up immunity after completing vaccination, he was likely to have been infected before he was conferred protection after vaccination."
As he had been identified as a close contact of the 39-year-old man, he was placed on quarantine on 18 April at a dedicated facility.
The man was tested during quarantine on 19 April and his result was negative for COVID-19. He subsequently developed a cough and sore throat on 25 April and reported his symptoms. He was conveyed to the National Centre for Infectious Diseases (NCID) the next day.
His test result came back positive for COVID-19, and his serology test is negative.
The MOH said that the number of new cases in the community has increased from nine in the week before to 11 in the past week. The number of unlinked cases in the community has remained stable at four per week in the past two weeks.
7 cases linked to new cluster named after Westlite Woodlands Dormitory resident
As part of the investigations into a 35-year-old Bangladeshi man who resides at Westlite Woodlands Dormitory and was confirmed to have COVID-19 on 19 April, the MOH and the Ministry of Manpower commenced special COVID-19 testing operations to test the dorm residents there, including recovered workers.
To date, 24 recovered workers were found to be positive for COVID-19, said the MOH, adding that they were immediately isolated and conveyed to the NCID.
The MOH said it – together with an expert panel which comprises infectious diseases and microbiology experts – investigated these cases to assess if they are re-infection cases, or past infections who are shedding minute fragments of the virus RNA which are no longer transmissible and infective to others.
Of the 24 cases, 11 cases have been assessed to be shedding virus fragments, and five are likely to be cases of COVID-19, the ministry added.
Two more cases have been determined to be negative for COVID-19 upon re-testing, and the remaining six cases are pending assessment by the expert panel.
All five re-infection cases occupied the same room at Westlite Woodlands Dormitory, along with the 35-year-old Bangladeshi manand his roommate, a 32-year-old male compatriot. The latter two have been fully vaccinated.
The MOH said there is currently no evidence of transmission to the rest of the dorm. Altogether, they form a new seven-case "Case 62181" cluster, named after the 35-year-old man's case number.
Among the five re-infection cases, two had recently arrived from Bangladesh on 6 April, the ministry added.
"Our epidemiological investigations found that they were likely to have been infected while overseas, and passed the infection to the others in the room. Further epidemiological investigations are ongoing at their workplace," said the MOH.
11 imported cases, including 2-year-old girl
Among the 11 imported cases, one is a Singaporean while three are permanent residents – including a seven-year-old boy – who returned from India, Ivory Coast, and Kazakhstan.
A 52-year-old Singaporean man who returned from India and a 52-year-old male PR who returned from Kazakhstan are among Tuesday's five symptomatic cases.
Two girls aged two and five are dependant’s pass holders who arrived from Nepal. The elder girl is among Tuesday's five symptomatic cases.
Four cases are work permit holders who arrived from India, Indonesia, and Malaysia, of whom one is a foreign domestic worker.
The remaining case is a student’s pass holder who arrived from Malaysia. The 49-year-old woman is among Tuesday's five symptomatic cases.
All 11 imported cases were placed on the stay-home notice upon their arrival here and were tested while serving their notice.
99% of total cases have recovered
With 22 more patients discharged from hospitals or community isolation facilities on Tuesday, 60,704 cases – or 99.4 per cent of the total – have fully recovered from the infection.
Most of the 108 hospitalised cases are stable or improving, while none is in the intensive care unit.
A total of 221 patients – with mild symptoms or are clinically well but still test positive – are isolated and cared for at community facilities.
Apart from the 30 patients who have died from COVID-19 complications, 15 others who tested positive for the virus were determined to have died from unrelated causes, including three whose deaths were attributed to a heart attack and another four, whose deaths were attributed to coronary heart disease.
Among the 198 confirmed cases reported from 21 to 27 April, 74 cases have tested positive for their serology tests, 80 have tested negative, and 44 serology test results are pending.
