Not entirely true, asymptomatic carriers are significantly less likely to transfer the virus to other people and thus if the vaccines (as is reported) stop most people from developing symptomatic covid, then they should also reduce infection rates. It's not impossible to catch it just from someone breathing near you, but the viral dose in a cough or sneeze is MUCH higher, and risk of infection is directly tied to viral dose.
There is strong evidence that Covid is infectious in
pre-symptomatic individuals (infected, no symptoms, later go on to develop symptoms) but
absolutely none that it's highly infectious, or even infectious at all, in infected people who never become symptomatic due to functional immunity.
The major problem of course is that if someone tests positive but has no symptoms, you have no idea if they're pre-symptomatic or truly asymptomatic until 5 to 10 days after exposure.
What makes this a bit of a mess with the vaccines is that double jabbed people who are exposed and infected with covid will;
1) Probably NOT develop symptoms (being functionally immune),
2) Thus, will probably NOT ever be contagious... but...
3) WILL probably test positive.
And so... pingdemic etc.
