Well, like we were told, homemade masks only protect others from you. So for homemade masks to work, nearly everybody has to be wearing them. I am assuming employees were not wearing N95s, but either surgical or homemade masks, and were exposed to a bunch of maskless people. So thus they were not protected. Also, in restaurants, people usually talk to each other, and to employees when they order, so bunch of virus particles are going to be flying around. So, people, if you really really really want to go to a restaurant, pick one with outside sitting area-less of chance to get covid.Interesting. If the employees got it so soon after reopening, it seems a good premise that they got it from their customers (who of course were not masked). I wonder if it entered through the eyes or whether, like so many people, they were wearing their masks below their noses (I see this all the time). It's great that restaurant personnel knew that loss of sense of smell was a key early symptom, but unfortunately, it's also one of the less common symptoms (although everyone who loses their sense of smell suddenly should be tested, of course).
Shutting down again was the right response (until everyone in the restaurant tests negative...10 days after last contact with the other employees) My worry would be that one more employee will test positive, and that will reset the clock.
The case above was in Texas, btw. Restaurant appears to have all its tables indoors (and widely spaced).
France just allowed indoor dining to resume yesterday, about a week after allowing outdoor dining. Daily new cases in France are bumping along at about 20-25% of what they were at their peak. Daily deaths are continuing to drop, seeming to plateau at around 25 per day (but it's too soon to know what reopening will do - it's only been slightly more than a week).
