Health director-general Dr Noor Hisham Abdullah said the cluster in Bukit Bintang involved nine Bangladeshis and a Malaysian.
One of the foreigners, he said, had tested positive on June 15 when undergoing screening before returning to work.
“Seven out of the 10 positive cases were housemates,” he said during his daily briefing here.
Noor Hisham said that their residence has since been disinfected and health officials are investigating the source of the infection.
The ministry is also investigating if the Malaysian had any links to the foreigners.
Another cluster was detected at a construction site in Kuching, Sarawak. It was detected when a supervisor at a construction site tested positive after undergoing a Covid-19 test at a private clinic.
The patient had close contact with two Indonesian workers.
“Subsequently, 426 close contacts had been identified, 62 of whom tested negative. Results for the remaining 364 are still pending.”
The ministry was still probing the source of the infection.
Meanwhile, three individuals tested positive for Covid-19 at a condominium in Hulu Langat, which involved a tahfiz student.
The tahfiz student’s uncle, a foreigner, later contracted the virus after visiting his nephew. And the man went on to infect his colleague.
Noor Hisham said to date, 40 of their close contacts had been identified and screened. Of the total, 26 were foreigners and the remaining Malaysians.
Thirty tested negative, while seven are waiting for the results.
Noor Hisham said there was no need to place these three areas under an enhanced movement control order (EMCO) or semi-EMCO for now.
“The clusters are under control.”
When asked why new cases kept emerging from the Pedas cluster despite multiple tests, Noor Hisham said it could be down to two factors — individuals being exposed to friends who tested positive and the lack of social distancing.
“Based on our experience from the tahfiz cluster, they tend to mix around at night, despite being under quarantine.
“So instead of social distancing, they get together,” he said, stressing they were not exposed to the community as they are under quarantine.
