Not all states delayed lock-down measures. NY dragged their feet and encouraged keep living as normal - under 40 or 50 yr. olds to carry on the social/nite life. I understand no one wants to be an alarmist. No special directives for seniors. Even California took a protective course.
Regardless - I think many heavily-populated tourist cities have had this virus spreading around since November. I've never been around so many people with colds, sore throats, red eyes, etc., (housekeepers to service oriented operators - manicurists, dentist, hair stylists) in my entire life. Quick cares stuffed full with people - (more than one visit) younger people (older ones, also) - 20 to late 40s that I'm aware of. Call it the flu - I'm not so certain. This area is crawling with Chinese who travel back and forth monthly/weekly and live both places. Not good odds.
