If those idiots who were wearing bum-nappies around two decades ago behaved decently we would be able to get on top of this a lot faster and people would no longer need to be 'wearing nappies on their face'. (I know that the idiot young are really infuriating the sensible young who are being given a collective bad name due to the idiots.) Quarantining for travel from other countries will only go away when the idiots in those other countries learn to behave too.
Don't go 'blaming' our (collective) governments for this mess. Blame the PRC for their gross ineptitude in letting their most famous ever export get out to infect the world. And blame the idiots who aren't behaving properly and putting so many peoples' jobs and futures (and their own) at risk
Airlines should be very, very heavy-handed with idiots who misbehave and put the livelihoods of those in the industry at risk.
