SINGAPORE — The Ministry of Health (MOH) on Monday (June 18) added three locations — all of them supermarkets — to a list of public places that had been visited by Covid-19 patients during their infectious period.

In its evening update on the coronavirus situation in Singapore, the ministry said that the infectious patients had visited:

• Sheng Siong supermarket at 7 Jurong West Avenue 5 on June 9 between 7.50am and 8.20am

• NTUC FairPrice supermarket at 447A Jalan Kayu on June 15 between 6.25pm and 8.55pm

• Sheng Siong supermarket at 19 Serangoon North Avenue 5 on June 19 between 5.15pm and 6.05pm

MOH said that it would have already notified individuals who had been identified as close contacts of the confirmed cases.

"As a precautionary measure, persons who had been at these locations during the specified timings should monitor their health closely for 14 days from their date of visit," the ministry said.

"They should see a doctor promptly if they develop symptoms of acute respiratory infection (such as cough, sore throat and runny nose), as well as fever and loss of taste or smell, and inform the doctor of their exposure history."

Members of the public do not need to avoid places where confirmed cases of Covid-19 have been, MOH said.

The National Environment Agency will engage the management of the affected premises to provide guidance on cleaning and disinfection, it added.

On Monday, MOH announced 218 new Covid-19 cases in Singapore. Among them, a work-permit holder was identified as a community case, while the rest were migrant workers in dormitories.
