Here in Asia, pre-pandemic, it was normal for people to wear masks in ‘flu season and doctors say that good ventilation helps keep the virus numbers down. A few outbreaks of Covid here have been caused by poor ventilation.I suppose you think that everyone should walk around wearing a mask over the winter flu season too? Improving building ventilation is another one. Yeah right, let's open all the doors and windows in the pub in the middle of January and freeze our nuts off shall we?
Honestly, some of you on here seem to think that our lives should revolve around obsessing about whatever virus is currently doing the rounds and trying not to catch it.
I fail to see why you have such an issue with this.
