SINGAPORE: Singapore reported 596 new cases of COVID-19 on Sunday (Apr 19), bringing the total number of infections in the country to 6,588.
Of the new cases, 68 per cent are linked to known clusters, while the rest are pending contact tracing, the Ministry of Health (MOH) said in its evening update.
The vast majority were work permit holders residing in foreign worker dormitories, it had said in an earlier press release announcing the preliminary numbers.
"The main increase today continues to be for work permit holders residing in dormitories, in line with our continued efforts to actively test and isolate the infected workers.
"Most of these cases are young, have a mild illness and are being monitored in the community isolation facilities or general ward of our hospitals. None of them is in the intensive care unit," said MOH.
A total of 544 cases from Sunday were linked to work permit holders residing in dormitories.
There were five new clusters identified as well at Woodlands Lodge I, Changi Lodge II, 51 Paya Ubi Industrial Park, 17 Jalan Besut and Sembawang Shipyard.
CASES WITHIN THE COMMUNITY
There were 30 cases within the community, the ministry added. Twenty-five were Singapore citizens or Permanent Residents, while five were work pass holders.
Among the community cases, five were children aged between one and 12 years.

In a clarification regarding Saturday's release, MOH said on its website that the COVID-19 daily update had included cases that were confirmed and verified after 12pm.
These cases had been included in the clusters case listing, the ministry said in a notice on its website.
"We have amended the listing to exclude them from the Annex of the 18 April press release," the ministry added.
Citing significant public interest, MOH has begun releasing the daily numbers earlier in the day, while sharing details on the cases at night.
CONSTRUCTION SECTOR WORKERS PLACED ON STAY-HOME NOTICE
The Ministry of Manpower announced on Saturday that all work permit holders and S Pass holders in the construction sector would be placed on mandatory stay-home notices.
While the recent rise in number of foreign workers infected with the coronavirus has mostly been concentrated in dormitories, there have been cases at construction worksites, MOM and the Building and Construction Authority (BCA) noted.
"Contact tracing suggests that transmissions at common construction worksites may have contributed to the increase in numbers," said MOM and BCA.
"Thus far, the cases detected among workers living outside the dormitories have been low. All those infected and their close contacts have been isolated."
Employers whose workers are affected by the latest stay-home notice are required to make arrangements for them such as providing food, and ensuring that their addresses and mobile phone numbers registered with MOM are up to date.

Sunday is day 13 of Singapore's month-long "circuit breaker" - a period with enhanced safe distancing measures in a bid to stem the spread of COVID-19. Most workplaces are closed and schools have transitioned to full home-based learning.
The Prime Minister said there are "a few early signs" that the circuit breaker is bringing down local cases in the broader community.
"But we are still worried about hidden cases circulating in our population, which are keeping the outbreak going," he added.
"The next few days will be critical. All of us must do our part, in order to defeat COVID-19."
