It ended when people stopped believing in/accepting the charade of pointless lockdowns & useless masks...
I am not downplaying the fact that the virus certainly affected certain groups of people really badly but the majority of us it was never a threat and the response to it was frankly insane.
WHO is finally catching up.
I personally think that the NHS backlog (people with conditions that were not diagnosed and treated during lockdowns which led to worse outcomes), the effect of repeat lockdowns on mental health & the immune system and the poverty caused by the damage to the economy have done more harm than the virus itself.
The response to Covid was a sad example of collective madness and hysteria and governments that were only too willing to control their population, and politicians who used the pandemic as an opportunity to make money with shady deals.
