SINGAPORE: Five discharged patients who had been warded at Tan Tock Seng Hospital (TTSH) and three visitors are among the 11 new COVID-19 cases linked to the cluster there.

Another two cases are patients, while the remaining case is a physiotherapist, said the Ministry of Health (MOH) on Sunday (May 2). 

All the new cases are linked to Ward 9D.

The TTSH cluster, Singapore’s first hospital COVID-19 cluster, has grown to 27 cases since a nurse who works in Ward 9D tested positive for the virus on Apr 27.

All 12,000 staff members will also be tested. About 7,000 employees have been swabbed and priority will be given to swab staff members working in clinical areas over the next few days.

“Epidemiological investigations are ongoing. In the meantime, all the identified close contacts of the cases have been isolated and placed on quarantine, and will be tested at the start and end of their quarantine period so that we can detect asymptomatic cases,” said MOH.

“We will also conduct serological tests for the close contacts to determine if the cases could have been infected by them.”

The TTSH cluster is Singapore’s first in a hospital and currently the country’s largest of nine active clusters.

Since a nurse first tested positive for the virus on Apr 27, four hospital wards have been locked down and close contacts of those infected, including patients, visitors and staff members who have been in the affected wards have been quarantined.

Singapore reported 39 new COVID-19 cases on Sunday. 

Besides the 11 people linked to the TTSH cluster, there are three other community cases and 25 imported cases. There were no new cases in the dormitories.
