Letters | Fourth wave or not, Hong Kong must get tough on social distancing

In my opinion, the increasing number of Covid-19 infections is really due to the four-day holiday two weeks ago, as some people didn’t wear masks when they went hiking or played sport. The government should tighten social distancing measures as soon as possible in order to delay or even prevent the fourth wave of Covid-19, otherwise the situation will be even more serious than anything we have seen so far, as most experts have warned.
Mask rules are essential to dealing with this virus, no matter if people are in indoor places or outdoors, and the rules must cover exercise, or else there will be some people who think they don’t have to wear masks because they are running, even though they are so slow as to be really walking.
Besides, citizens also have the responsibility to be self-disciplined and aware of virus prevention measures, such as maintaining social distance and following the four-person limit on public gatherings – rules which have been repeatedly flouted by bar patrons and hotel guests.
I sincerely hope we can fend off the fourth wave but, for that to happen, we will need to be on our guard together.
