It would be easier to believe this if all of the other causes that have been put forward actually turned out to have been the case, like:
- Security Guards having sex with returnees (no evidence this ever happened)
- BLM protesters
- Ethnic/Religious groups doing the wrong thing
And so on and so forth. What happens is that:
- Cityfolk blame suburbia
- Regional blame metro
- Other states blame victorians
Yet people all over the world are catching this because it's infectious and despite what we might think, just because we're locked down doesn't mean supermarket staff, medical staff, transport staff, utilities workers, construction workers and so on and so forth are also.
The nursing homes are a great example. The virus got into them, a few residents caught it, staff caught it, they went home and their partners and children caught it, and so on and so forth. Why do the numbers continue so stubbornly despite Stage 4 lockdown? Because people can't necessarily isolate themselves entirely from all other people regardless of the current stage of restrictions, and what one person catches one day can easily spread to others in a household/facility/office building/residential high rise building the next day.
