Hong Kong on Saturday set new conditions for incoming travellers from countries deemed high risk, which mean arrivals need an official certificate to prove they have tested negative for Covid-19.
The new measures, effective from midnight (1600 GMT) next Saturday, were announced as Hong Kong grapples to stop a new wave of infections spreading, with dozens of new cases being reported daily. Hong Kong has seen a total of 1,714 coronavirus infections and 11 deaths.
The newly gazetted conditions will affect travellers who have visited Bangladesh, India, Indonesia, Nepal, Pakistan, Philippines, and South Africa in the 14 days before arriving in Hong Kong, with the aim of stamping-out the number of imported cases. Hong Kong's government expressed concern at the 234 imported cases there were reported between 20 June and 27 July.
Those entering the territory will need to produce a letter or certificate with the name of a health care provider or laboratory who ran the test that shows the result as negative. An official letter from a government certifying approval of the laboratory of health care institution is also required, as well as confirmation of a hotel booking for 14 days.
 Aircraft operators are tasked with giving a document to the Department of Health before arrival that confirms travellers being checked in for flights to Hong Kong have produced the relevant documentation. Violations are punishable by fines of 50,000 Hong Kong dollars (650 US dollars) for operators and 10,000 Hong Kong dollars for passengers, with the possibility of up to six months imprisonment for both.
