First case in Westlite Juniper cluster detected on July 24
The first Covid-19 case linked to the currently active Westlite Juniper dormitory cluster was detected on July 24 through rostered routine testing, the Ministry of Manpower (MOM) said yesterday.
The cluster comprised 48 cases as at yesterday. It was announced on July 27 by the Health Ministry, and comprised nine cases then.
In a statement to The Straits Times, MOM said six other cases in the cluster were close contacts of the first case.
The remaining cases linked to the dorm located in Mandai were detected either through pre-emptive testing at the dormitory and quarantine facilities, or through rostered routine testing.
"They were either asymptomatic or had mild symptoms, and have been moved to a healthcare facility for further care and treatment," said MOM.
It added that the close contacts of the infected cases have been isolated, and that pre-emptive swabs were conducted on all residents of the dormitory to quickly detect, isolate and contain other potential cases.
"In addition, all residents will be on seven-day rostered routine tests to quickly ring-fence potential transmission at the dormitory," said MOM.
Westlite Accommodation, the dormitory's operator, said the dorm housed 1,408 residents last month, about 500 fewer than its licensed capacity of 1,900.
Following the detection of this cluster, about 500 residents were moved in batches to government quarantine facilities, it said.
It added that 380 of these residents have since returned to the dormitory, and that all current residents of the dormitory have been cleared for work.
It also said that since the outbreak of Covid-19 in Singapore last year, it has implemented and continually enhanced infection prevention control and safe living measures.
For instance, workers are grouped in smaller "bubbles" to reduce mingling, and groups are assigned different walking routes as well as pick-up and drop-off points within the dorm.
As at Wednesday, more than 80 per cent of Singapore's Covid-19 cases have been dorm residents, although the number of new daily cases reported among this group has largely been in single digits since October last year.
