The government of Hong Kong has tightened measures for travellers arriving from outside of China.
Travellers who have stayed in destinations outside China in the 21 days before arrival, must undergo compulsory quarantine in a designated hotel for 21 days, an increase on the previous 14 days.
The move was announced on December 23, and came into force just two days later on December 25.
Arrivals must undergo testing at community testing centres or designated quarantine hotels on the 19th or 20th day following their arrival, and are required to stay at their place of residence, private premises or place of quarantine specified on the quarantine order until the test result is available.
Hong Kong has also added a ban on travellers who have spent more than two hours in South Africa in the last 21 days, mirroring a similar ban in place on arrivals from the UK. These specific bans have been introduced in an attempt to stop the spread of new, more infectious variants of Covid-19.
Earlier this month Hong Kong temporarily banned flights from several carriers including British Airways and KLM, as the Special Administrative Region cracked down on imported Covid-19 cases.
