Singapore's first Covid-19 community case in 16 days is a Singaporean who works as a service engineer and had dinner with 12 family members at Seoul Garden in Tampines Mall last Saturday, the Ministry of Health (MOH) said yesterday.
The family had occupied three tables at the restaurant, and there was mingling among the groups.
Investigations are ongoing to assess if there had been any breach of the relevant safe management measures, MOH added.
The case is currently unlinked, and epidemiological investigations are in progress.
Meanwhile, all his identified close contacts, including his family members at the dinner, have been isolated and placed in quarantine. They will be tested at the start and end of their quarantine period so that asymptomatic cases will be detected, the ministry said.
The man, who developed a fever and sore throat on Monday, works at Master Systems Marine. His job entails going on board vessels docked at Marina South Pier and West Coast Pier for servicing and maintenance of ships' navigational systems.
He typically worked alone, and had no interaction with the vessel crew except for a supervising crew member. On days when he was not working on board vessels, he had remained at his office in Vertex Building Tower B, at 33 Ubi Avenue 3.
He reported that he wore a surgical mask during his work on board the vessels and at the office, and that safe distancing and safe management measures were adhered to, said the ministry.
After developing symptoms, he went to a general practitioner clinic the next day, where he was tested for Covid-19.
"We urge everyone to continue to exercise social responsibility, and to cooperate with the prevailing measures.
"This is yet another reminder that the virus has not been eradicated and that new cases and clusters can easily emerge in our community if we let our guard down," said the ministry.
