The announcement came on 5 January 2021, as new virus variants of COVID-19 with higher transmissibility have been reported to be circulating in South Africa and the UK.

Therefore, all persons who have stayed in South Africa or UK for more than two hours in the 21 days before boarding will not be allowed to board the flight to Hong Kong.

Based on the same consideration, the Department of Health will invoke the Prevention and Control of Disease Regulation (Cap. 599H) to prohibit vessels which have visited South Africa or UK in the past 21 days from entering Hong Kong waters,

...the Hong Kong Center for Health Protection said.

With effect from 3rd January, MPA Singapore has also banned all long-term pass holders and short-term visitors with recent travel history to South Africa within the last 14 days, including crew.
