Guess what? They'll find infections. Just like when I go to my fridge, I find cold things.
Now, if they really wanted to find out the scale of the problem, they'd do random tests at non-specific locations. Then they might get some idea of the real spread of the problem.
There was a CNN story that a woman went to a state in the US with a low vaccination rate and got Covid. Wrap your head around that for a minute. Meanwhile at least hundreds of people in her own state surely got Covid the same day.
With the billions of Covid shots around the world, surely some people have died soon after getting it. I would wager that statistcally, some people must have suffered heart attacks while waiting in line to get their shots.
God, the media sucks.
