Since covid, the flu, and most viruses are transferred through the lungs, nose, ears, and eyes then yes washing your hands absolutely helps prevent getting sick. Have someone with the flu cough on your hands and then go and pick your nose. You 100% get the flu.
Masks are a joke though. Unless it is form fitting and tight it isn’t really helping anyone.
Of course what you said would happen, have them cough on your hand and stick it up their nose. No one is going to go do that or seek out wuflu patients and have sex with them
Im just saying rational people do not need to change their behavior because of this "pandemic" I haven't changed my behavior and caught it. All the people not going to the gym because of the wuflu thinking they are becoming healthier, how stupid can people be? People who wear masks but continue to smoke cigerattes? LOl, they are clowns
