His test result came back positive the next day, and he was conveyed to the National Centre for Infectious Diseases (NCID) in an ambulance.

His serological test result has come back negative, indicating that this is likely a current infection.

He received his first dose of Covid-19 vaccine on January 18, and the second dose on February 8.

He was tested for Covid-19 infection and his test result was negative.

He was subsequently warded in Ward 7D then transferred to Ward 9D on April 20. As he had persistent fever, he was reviewed by an infectious diseases physician, and transferred to an isolation ward on April 27.

Other five cases from TTSH cluster

Cases 62567, 62568, 62573, 62574 and 62582 are patients warded at TTSH’s Ward 9D, and were detected after patients in Ward 9D were tested for Covid-19.

Amongst them, three are asymptomatic, while Cases 62567 and 62568 developed fever and/or acute respiratory infection (ARI) symptoms on April 25 and April 28 respectively.

Lockdown of Wards 7D and 9D

TTSH has locked down both Ward 7D and Ward 9D.

Testing for staff and patients who have been in both wards is still in progress. All close contacts of the cases, including patients, visitors and staff who have been in the affected wards, will also be placed on quarantine.

As a precautionary measure, all patients and staff in other TTSH wards will also be tested for Covid-19 infection, including those who are asymptomatic.

TTSH has also taken additional steps to minimise the risks of transmission.

Staff and patient movement in all the main wards has been minimised to prevent any cross-infection. From April 29, no visitors will be allowed into the hospital except for critically ill patients.

During this period, elective cases will be deferred except for those that are urgent, and A&E cases that are non-life-threatening will be redirected to other hospitals.

Seven more cases are linked to the Case 62517 cluster. Case 62517 is an Immigration & Checkpoints Authority (ICA) officer who was deployed at Changi Airport.
