This is the best summary I've seen on transmission risks of COVID-19, including indoor dining at restaurants, grocery stores, passing by joggers outside, workplaces and parties. Highly recommend reading this and sharing with people you know! https://www.erinbromage.com/post/the-risks-know-them-avoid-them?campaign_id=9&emc=edit_nn_20200511&instance_id=18384&nl=the-morning&regi_id=95475389&segment_id=27239&te=1&user_id=ff4ae4203edba98c5fdf031f7dc55c97

Things I learned:
Social distancing doesn't necessarily lower your risk for indoor dining/workplaces/houses of worship or indoor sports - air circulation caused spreading and infection well beyond 6 feet.

If you are outside, you would need to be in someone's direct airstream for 5+ minutes to be infected. Passing people, even if they are breathing heavy, does not provide enough "dose" for infection.

"All these infection events were indoors, with people closely-spaced, with lots of talking, singing, or yelling. The main sources for infection are home, workplace, public transport, social gatherings, and restaurants."

"But even if that cough or sneeze was not directed at you, some infected droplets--the smallest of small--can hang in the air for a few minutes, filling every corner of a modest sized room with infectious viral particles..."

"...All you have to do is enter that room within a few minutes of the cough/sneeze and take a few breaths and you have potentially received enough virus to establish an infection."
