Something I’m not sure I’ve ever seen a straight answer on is whether someone who is asymptomatic is more or less likely to spread the virus. Is the reason that a person doesn’t have symptoms because their viral load is lower and they are likely shedding less viral particles, or is it the symptoms that spread the virus, or is an asymptomatic individual just as likely to be a super spreader? I would imagine that someone who is symptomatic (coughing, sneezing, breathing hard) is inherently shedding more virus as a result of those symptoms, and therefore more likely to pass it on to others than someone who is merely talking and breathing normally. Although they are still aerosolizing and creating some droplets, it should be a lower amount. This could explain why children (who typically experience less severe symptoms) aren’t thought to spread COVID as much as adults, in general.
