our surveillance testing is certainly better than it was and as nick mentioned about one-seventh of positive tests are then going and getting their genomic sequence done to foind out which variant it is. we shouldn't be surprised if omicron is here. over the summer we stopped testing. we had a real lull in testing. we talked a lot about this idea of having plenty of home tests. they are more available now but i think people have not been using them as much as they could. antigen tests, dana, are good for answering the question people are really often trying to ask, which isn't do i have the virus in my body. the question they're asking is, am i contagious? i feel fine, but am i possibly contagious? because people without symptoms can spread those antigen tests can do a great job answering that question. people can buy them in stores. i've been buying them going into the cooler drier months, have them at home.
