If this is true, it means that all restrictions about being outside are counterproductive, in that people aren’t getting enough vitamin D, which is apparently prophylactic. You know, like Adolf Whitmer’s dictate that you can be in a boat as long as it doesn’t have a motor, or being able to surf but not swim. It probably also means that sporting events are safe if not in enclosed environments. If it takes more than two hours or so, movie theaters are probably OK as well, and so are restaurants.
The cases of prolonged exposure we’re seeing are nursing homes (thanks, Andy and governor of Pennsylvania!) and factories, particularly meat packing, where people are at close quarters for long periods of time.

This also explains high rates of infection aboard naval vessels, but because sailors tend to be young and healthy, also why most haven’t gotten sick. It also means that it was dumb of NASA to restrict viewing at the Cape of the upcoming crew launch next week. It’s probably perfectly safe to gather on the beaches and causeway.
