@lioness- There are a lot of speculations where COVID-19 lives. This morning there was also an article in the NYT concerning the virus and being indoors.

Linda, from the beginning there have been tons of speculations about where it lives, how long it lasts, how it's spread and it has driven us all batty. There are people who take a long time to recover and are ill for long periods of time. There are people who exhibit no symptoms but they test positive. The same safety regulations still hold true and will keep you the safest. Wash your hands often and for 20 seconds, stay away from crowds, even if you wear a mask. Keep at least 6 feet apart. I hope that you are still doing all of these things to stay safe. It's the best that we can do. Try not to pay attention to unusual cases, they will further the feeling of battiness!
