Govt quick to explain entry quarantine not beneficial/worth it when we were experiencing peak, as visitors lower than usual and any infectious entrants not going to significantly uplift overall numbers.
They are adamant its critically important now, as our numbers now significantly reduced from peak, so any new infectious people arriving could uplift our reduced numbers by significant percentage. However, they also stress that UK entrant numbers are currently 99% less of precovid19..
However, the bigger question is, if its critically important when our infection numbers are low, as in now. Why wasnt it implemented when Boris was still shaking hands with everyone in the hospital, when our numbers were negligible, particularly as number of UK entrants at that point was still close to normal...eg huge in comparison to now
