The thing is hotel quarantine is adequate on the whole for the nature of the covid19 virus currently - no doubt improvements can be made, but people will stuff up, and then being a virus it will find ways to get out. The virus getting out of quarantine in this case is almost inevitable - it is how leaders handle the situation when it gets out that they should be really judged on and on that front idiots doing a lockdown for 1 case should be graded with a Z-.
