I've been looking at this for a long time because I have anxiety about all infectious disease. Not just covid. Many viruses are not robust enough to spread easily in casual settings. Covid seems to be fitting somewhat in that category. For a disease with no vaccine or herd immunity, we would be seeing overwhelming case numbers everywhere if casual contact was the culprit.
This is one area where anecdotal observation is useful. We would be crippled by cases if grocery stores were driving the spread, for example.
I have researched some of the more contagious diseases (measles, chicken pox) and most consider contacts to be someone you had a face to face encounter with for a certain period of time. Both measles and chicken pox are more contagious than covid. We should use what we know collectively about infectious disease and covid to make common sense decisions. Chicken pox was a disease people almost exclusively caught from extremely close knit situations. Everything I've read about covid seems about the same. Some kind of close and prolonged behavior with an infected human. This is the data being left out of every fear peddling article we read and it's part of why people are not seeking treatment for other problems when they need it. Enough. Time to be adults and talk about this in a way that could possibly help allay at least some fear. This is no way for anyone to live when they likely have a lot of findings by now about low risk versus high risk. It's criminal to allow our at risk population to wallow in desperate panic.
This. FL is allowing WDW to open, yet there are patients in nursing homes that have not seen any family or friends in months. There is no reason if the first is allowed, that the second could also be - with tight restrictions. One visitor per day, for 10 -20 minutes, wearing a mask and gloves. Families/friends could set up a schedule. Perhaps only one visiting day/week/patient. Stagger them so there aren't more than one or two family members in the facility at a time.
In the beginning, the virus may have been brought in by families - but was just as likely to be spread by caregivers. Let the patients/family/facility weigh the risks versus benefits on a case by case basis. If they are concerned that they can't isolate patients, then that might be reason to disallow visitors.
