Most of the people who i have talked to who got infected will recall a lapse in judgment that may have lead to the infection. Almost all of them recalled having an instance wherein they lowered their mask. It was either to scratch an itchy nose or to talk clearly on the phone.
Now the question is why is one person's mask lowering will result in an infection while you see a lot people outside doing the same thing yet not getting infected?
I guess this is my understanding on how people get infected and how the virus infects.
A person needs a minimum critical viral load to produce the Covid19 infection. The amount needed is different from person to person which is based that persons immune response/health/age/etc. Older and immune compromised patients may need a lower viral load than a healthy young adult. The guidelines set by the WHO/CDC/IATF will prevent healthy people from getting the critical viral load to produce a covid19 infection. Proper mask wearing, social distancing, hand washing, etc will prevent excess or large amount of viruses to enter our body. Certain area's and situations increase or decrease to chances of getting a critical viral infection load.
Talking/interaction with an a/symptomatic Covid + patient doesn't necessarily mean that you will get infected too, if you follow all suggested protocol then chances are you might not get infected although you might get labeled as PUI. Increased talk/interaction with the covid+ patient will also increase your chances of getting the critical viral load, that is why in the latest WHO/CDC (not sure which one) Guidelines states a minimum social interactive time. They suggest a minimum interaction of 10 mins i think. Sorry i can't seem to find that link.
