If you're coughing and sneezing consistently for no apparent reason, then you should be self-isolating and not going out in public. That's the main form of transmission in droplets in the air (hence why the 6ft distance) or on surfaces. If it was transmitting from breathing around people, a lot more people would be sick. And if you think it's transmitted through breaths of air, that mask isn't going to stop it.
Around the Super Bowl I was struck with an odd illness. I never experienced symptoms like that before. I checked the symptoms of coronavirus back then and it didn't match. Today I read the symptoms... maybe. I know I can trace it to a birthday party at a Chicago Pizza restaurant that I attended. Three people total, two adults and a child, who attended this party got sick at the same time afterwards. I conferred with the others and the other adult (the birthday boy) had near identical problems virtually in parallel. We started feeling sick at the same time. We were bed-ridden at the same time. Recovery was about the same time. At the time, the news about kids not being affected much from coronavirus did not reach the US. The kid that was at the party that got sick only had a minor illness. Was it coronavirus? I do not know. But I attended a Super Bowl party within a week afterwards with over a dozen people while I was as they say "asymptomatic" if it was coronavirus and then bed-ridden the next day and no one else got sick at that party. My family didn't get sick either.
