The Ministry of Health (MOH) confirmed 12 new cases of Covid-19 infection on April 27.

This brings the total number of cases in Singapore to 61,063.

Sole community case

There is one case in the community today that is linked to a previous case.

Case 62485 is a 42-year-old male Indonesian national who is a sea crew working on board bunker tanker MT ALLI.

He had not disembarked from the vessel except to go for his Covid-19 vaccination.

He was placed on quarantine at a dedicated facility on April 18 as he had been identified as a close contact of Case 62113.

He was tested for Covid-19 during quarantine on April 19 which came out negative.

He subsequently developed a cough and sore throat on April 25 and reported his symptoms.

He was conveyed to the National Centre for Infectious Diseases (NCID) the next day where his test result came back positive for Covid-19 infection, and his serology test is negative.

Case 62485 received his first dose of Covid-19 vaccine on April 8.

As it typically takes a few weeks for an individual to build up immunity after completing vaccination, MOH said that he was likely to have been infected before he was conferred protection after vaccination.
