Three visitors to Tan Tock Seng Hospital (TTSH), a pharmacist and one patient made up the five Covid-19 cases linked to Singapore's largest active cluster yesterday.
All of them were detected from the proactive testing of patients, visitors and staff at TTSH or their close contacts, and had already been placed on quarantine, said the Ministry of Health (MOH).
In total, 40 cases are now linked to the TTSH cluster.
Covid-19 cases in the community continue to rise, with the number of new cases increasing to 64 in the past week from 11 in the week before.
The number of unlinked cases in the community has also increased to 10 cases in the past week from four cases in the week before.
Three of the cases had visited Ward 9D between April 18 and last Wednesday.
The remaining two cases are a TTSH pharmacist and a patient at Ward 9D.
The 25-year-old Singaporean pharmacist had interacted with patients and staff at Ward 9D on April 20.
He was last at work last Wednesday.
He developed a mild runny nose last Friday but this was resolved on the same day, said MOH.
Last Saturday, he was tested for Covid-19, and placed on quarantine on early Monday morning.
His result came back positive on the same day. His serology test result is pending.
