In an interview with the New Sunday Times, Professor Datuk Dr Awang Bulgiba Awang Mahmud said new clusters involving migrant workers were particularly worrying.
The number of undocumented workers in Malaysia, which amount to up to three million people, and their prevalence in almost all industries, including construction, food and beverage, manufacturing and the services sector, have been regarded as a potential catalyst to the formation of new clusters.
This has been complicated further by the fact that around 80 per cent of those with Covid-19 are asymptomatic or show little or no symptoms. It is also compounded by the fact that Covid-19 symptoms can take up to 14 days to appear.
