He said three cases were found in the Jalan Lima cluster, nine from the Kebun Baru cluster, one from the Teknologi Emas cluster and four from the screening of close contacts.
The Jalan Lima cluster spans the Sepang and Hulu Langat districts in Selangor, while both the Kebun Baru cluster and Teknologi Emas cluster were detected in Kuala Langat, Selangor.
It was reported on April 1 that the B.1.351 strain of the Covid-19 virus — which was first reported in the UK and South Africa last December — is being transmitted locally.
The South African B.1.351 variant was first detected in Malaysia earlier this month, with four cases found. Early investigations found all four cases were closely linked to the Jalan Lima cluster.
Two of the cases believed to be from the Jalan Lima cluster were employees of a company based in the Kuala Lumpur International Airport. Of the other two cases, one was from the Kebun Baru cluster, and one was a family member of an infected Covid-19 patient.
