Mustafa Centre, Rasapura Masters at The Shoppes at Marina Bay Sands and vehicle inspection centre STAI Jalan Boon Lay are among places recently visited by Covid-19 patients while they were infectious, said the Ministry of Health (MOH) yesterday.
It added that there were 20 new cases of the coronavirus in Singapore.
The full list of locations that infectious Covid-19 patients visited for at least 30 minutes can be found on MOH's website.
Those who were at these places at the same time are advised to monitor their health for two weeks from their date of visit.
There is one community case among the new cases. He is a work permit holder from India and the case is currently unlinked.
He was detected as a result of MOH's rostered routine testing of workers in the construction, marine and process sectors who are living outside the dormitories.
MOH said that he was asymptomatic. Epidemiological investigations of the case are in progress.
In the meantime, all the identified close contacts of the case have been isolated and placed on quarantine, and will be tested at the start and end of their quarantine period. MOH will also conduct serological tests for his household contacts to determine if he could have been infected by them.
Five imported Covid-19 cases were also announced. They comprise one work pass holder, three work permit holders and one dependant's pass holder. Four of the cases are currently employed in Singapore and arrived from India and Indonesia on Sept 14, and Brazil and the Philippines on Sept 13. The dependant's pass holder arrived from India on Sept 15.
All of them had been placed on 14-day stay-home notice (SHN) upon arrival in Singapore, and were tested while serving their SHN at dedicated facilities.
Migrant workers living in dormitories made up the remaining 14 new coronavirus patients, taking Singapore's total to 57,685.
Seven had been identified earlier as contacts of previous cases, and had already been quarantined to prevent further transmission.
