Infectious disease expert Dr Adeeba Kamarulzaman has cautioned against Health Minister Dr Adham Baba's suggestion that the three-day quarantine period for ministers may be extended to business travellers or the public in the future.

"I don't think this is a good idea at all. We might as well have no quarantine at all," said Adeeba, who is part of the Selangor task force for Covid-19 committee (STFC).
