I'm a bit out of the loop as don't have kids at school & am not planning to go abroad.
Are close contacts in schools having to get PCR tests even with no symptoms? And surge testing is for anyone in that area? How does anyone know that they are actual positives rather than remnants of a previous symptomless infection (given that's quite likely with children)?
And what about the Fit to Fly tests? What if someone caught covid 3 months ago but wasn't tested for whatever reason (no symptoms or household member tested positive, say) and it's now picked up? What a nightmare that would be!
Aren't we at risk of being caught up in a circle of positives that aren't really such? I'm not a conspiracy theorist, btw, and that's not the angle from which I'm coming.
