Difficult to call, though I think it is too co-ordinated across the western democracies for it just to be 'happenstance'.
It is also true that dissenting opinion is suppressed, virtually ignored by mainstream media and experts who do speak up do so at the risk of their careers and livelihoods. Only outliers like Icke and Wakefield seem allowed, but they are easily dismissed.
If it was an issue that has simply got 'out of hand', surely the government, with the experience gained earlier in the year, could have devised a strategy to move back to normality whilst protecting those at risk but there is no sign of that happening or that they even want to move in that direction.
In reality we are looking at lockdown and serious restrictions as a long term (permanent?) solution that is massively out of proportion to the real health issues. This will continue the destruction of economic and social life in the uk, quite why remains to be seen.
