Clav I thought you were the master of cut and paste.

Note especially the exemption "Passengers holding a new entry visa to work, study, establish or join in any business, or to take up residence in Hong Kong"
And the additional requirements "Passengers who are ending their journey in Hong Kong and have visited or transited through Bangladesh, Ethiopia, India, Indonesia, Kazakhstan, Nepal, Pakistan, the Philippines, South Africa, the United Kingdom (effective 1 October 2020 0:00, Hong Kong time) or the United States in the 14 days prior to arriving will be required to show the following documents."
The UK already has a list of countries that you have to quarantine after travelling to, the only difference is that in Hong Kong you have to have a good reason to be going there and you actually have to quarantine. There are regular reports of people with the quarantine band being set about by old ladies with their umbrellas when they try to venture out.
Like I say we are one of the plague capitals of the world.
You might also be interested in the Government's website which provides full timely details of every case, the building, how it was transmitted. airline seats etc so that Hong Kongers can make sensible decisions about how they go about their lives. No question of being told that you are in a hotspot when you have just spent time in hospital and worrying sick until you find out several days later that you are not in a hotspot at all because over a quarter of cases are in postcodes in other cities because Dido's systems are limping along so slowly and ineptly that they can't even provide prompt accurate data. www.coronavirus.gov.hk/eng/index.html
