Hong Kong: this is what a Third Wave looks like

Hong Kong daily new cases. From Worldometer 

Does this shake my scepticism about lockdowns? Not about stringent lockdowns. It seems the government didn’t check or quarantine incoming crews by air and sea. That didn’t help. Also we don’t know the source of 40% of the new cases, so we ought to know that before deciding on the form of lockdown.
Further: there’s zero evidence, as far as I know, that you can catch the virus at the beach or pool. For the pool you have three things against it: UV, open air and chlorine.
Meantime we’re back in a form of lockdown. Pools, beaches, schools, gyms, included.
Still, Yonden Lhatoo thinks we’re “staring into the abyss”.  I hope not. But I’ve given up predicting anything about this perplexing virus.
