That's the thing with SARS-CoV-2.
It's primarily transmitted by aerosols, but it has also been shown to be transmitted via smearing. It's primarily a respiratory tract infection, but it has also been shown to have intestinal, cardiovascular and neurological impact as well as persistence in these tissues [1].
And yet, despite 7 millions of people dead and dozens of millions of people suffering from long covid, there's almost no prevention mechanisms in force anywhere on this planet, even vaccine development and rollout have all but ground to a halt. It's like we learned nothing at all from the pandemic, our politicians just wanted to make it go away by pretending it went away.
