Seems fairly obvious that more cases are being reported now because (a) more tests being done and these are not restricted to hospital cases (b) lot of spread among among the younger population who have since lockdown was eased, been gathering en masse and (c) lots of people now coming back from holidays in Europe and bringing back infection with them.Numbers although high are probably a more actual reflection of infection in the community at large rather than as was the case back in March of just hospitalized cases or the vulnerable who copped the worst dose of it back then. If varied opinion is to be be believed, the infection rate back in March in the community was 5 times higher than official figures cited (these were not tested and went unreported). If looked at in this light the case numbers now are 5 times lower than back at the start of the epidemicI don't think the government is going for an official policy of herd immunity - this is just happening naturally as is the usual way with viruses.
