SINGAPORE - The sole locally transmitted case of Covid-19 reported on Tuesday (April 20) is a 35-year-old male Bangladeshi national who had received both doses of the Covid-19 vaccination.

He showed symptoms despite having received his first dose of the Covid-19 vaccine on March 12 and the second dose on April 13.

He is employed as a construction supervisor by Prosper Environment & Engineering and works at Sembcop Marine Admiralty Yard in the Admiralty area, said the Ministry of Health.

MOH said that he is likely to have been infected before he was given protection from the virus from the vaccination, as it takes a few weeks for an individual's immunity to build up after receiving the jab.

The work permit holder - who arrived in Singapore in July 2019 - is a dormitory resident and has been classified as a dormitory case.

He stays at Westlite Woodlands Dormitory in Woodlands.

He developed a runny nose last Friday, but did not report his symptom. On the same day, he was tested for the virus as part of the rostered routine testing programme.

His test came back positive on Sunday, and he was immediately isolated and taken to the National Centre for Infectious Diseases.

His earlier test results - the latest being from April 9 - were all negative, said MOH.

MOH added that epidemiological investigations are in progress, and that all his identified close contacts, including his dormitory and workplace contacts, have been isolated and placed on quarantine.

This is not the first case of an individual being infected after being vaccinated.

There were 13 other new coronavirus cases confirmed, all imported, for a total of 14 cases on Tuesday.

This takes Singapore's total to 60,865.
