Update: thanks to all of you who expressed concern for Mrs.Duckworth-she was perscribed some exremely powerful antibiotics and these are returning her to a healthier state. This suggests that she developed an infection following a standard illness rather than influenza. There is now testing near where I live, but it is very, very limited. We are expecting to have testing somewhat more available by early next week. We fully expect to be able to have her tested at that time, but I expect that the outcome will be good.
