Hong Kong was doing fine against Covid-19 until the resurgence of infections in early July. Since the third wave broke, the city government has been condemned for not implementing effective preventive measures to curb the virus, blamed for leading to uncontrollable community transmission and increasing deaths. One of the loopholes was the loose policy of allowing air and marine crews to move around the city before negative test results were confirmed. Locals kept urging Chief Executive Carrie Lam Cheng Yuet-ngor’s administration not to offer exemptions to quarantine rules, such as for seafarers and aircrew. Even so, it was not until Hong Kong had more than a week of 100 or more new positive cases a day that the government finally imposed stricter rules. It now requires flight crew to demonstrate a negative Covid-19 test before arriving in Hong Kong, while disembarking seafarers have to wait on board for their transfer to their next destination. It is mandatory to wear masks in public areas, including outdoor venues. There was also a total, albeit short-lived , ban on dine-in services last week. Even so, these policies have received significant negative feedback from multiple stakeholders. The International Air Transport Association , for instance, disagrees with testing pilots and cabin crew for Covid-19 before arriving in Hong Kong. Some people refuse to wear masks outdoors or do not wear them properly because they find it too unbearable in hot weather. Undoubtedly, our government has a lot of room for improvement. Amid the pandemic, however, those in charge do not need more finger-pointing. Constructive advice and encouragement are always needed, especially in times of adversity. Instead of lodging incessant complaints and criticisms, why can’t we be more united to fight against Covid-19 and leave the rest for later? Grace Pow, Ho Man Tin Salute to Hong Kong’s quarantine centre heroes In this era of doom and gloom where upbeat news is rarely to be found, we thought your readers would be uplifted to learn about an amazing group of people doing their best to truly help and serve others in the city. Commendations are in order for an indefatigable group of Hongkongers making a huge contribution to our community every day. For anyone who has had the misfortune of being ordered to one of the government quarantine centres in our city, you already know these blue-suited heroes. We are not sure if the people of Hong Kong realise that the selfless workers in these facilities are all volunteers. Our sincerest gratitude to these caring people for their words of encouragement to my family and for assisting us in many ways while confined in Lei Yue Mun Park recently. Words cannot describe how touching it was to witness these volunteers cheerfully performing a variety of thankless tasks in the heat, all for the betterment of the city and its people. It is a bright spot in a crisis such as this to have ordinary citizens giving so much back to their community. We should all salute them. Karie-Ann and Pete Grout, Pok Fu Lam
