The Ministry of Health (MOH) has confirmed 611 new cases of Covid-19 as of 12pm on Friday, May 29, 2020.

This brings the total number of reported cases in Singapore to 33,860.

The majority of the reported infections continue to be work permit holders residing in foreign worker dormitories.

There are three Singaporean or Permanent Resident cases, two Work Pass holders, and four Work Permit holders, reported on Friday.

1,337 more cases of Covid-19 infection have been discharged from hospitals or community isolation facilities. In all, 19,631 have fully recovered from the infection and have been discharged from hospitals or community care facilities.

There are currently 461 confirmed cases who are still in hospital. Of these, most are stable or improving, and eight are in critical condition in the intensive care unit.

13,745 are isolated and cared for at community facilities. These are those who have mild symptoms, or are clinically well but still test positive for Covid-19. 23 have passed away from complications due to Covid-19 infection.

Amongst the six Work Pass and Work Permit holders, five were picked up due to MOH's screening and surveillance.

Amongst them, three were tested as part of MOH's screening of migrant workers residing at shop-houses located at Balestier Road, due to their proximity to another cluster in the same area.

The other two were tested before they were due to start work on plumbing/ electrical projects at schools, as a precautionary measure to prepare for the safe re-opening of schools. The remaining case is a contact of earlier cases, and had already been placed on quarantine earlier.

Case 33,092 is a 49-year-old female Chinese national who works as a preschool staff.

She tested positive on May 26 as part of the ongoing active screening of preschool staff in Singapore, but was asymptomatic.

She is the 13th preschool staff to be confirmed with Covid-19 as a result of the active screening.

MOH previously said it would conduct a serological test to determine if hers is a past or current infection.

The serological test has come back negative, indicating a recent infection, MOH said on May 29.

However, serological tests for all the other 12 preschool staff were positive, which MOH said indicates they were "past infections" and were unlikely to be infectious by the time of the screening.

Here's the breakdown of the numbers.

Here are the public places visited by cases during infectious period.

Those who had been identified as close contacts of confirmed cases would already have been notified by MOH.

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.

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.
