The Health Ministry (MOH) fears that the Sivagangga infection cluster that started in Kedah could be linked to a genome of Covid-19 which had been identified as a superspreader in Egypt and Pakistan.

Its director-general Dr Noor Hisham Abdullah told a press conference today that they found the cluster - which MOH has traced back to the owner of a nasi kandar shop in Jitra - had been spreading "very quickly" compared to other infection clusters in the country.
