The daily number of cases according to Arizona's COVID dashboard have nearly doubled in the past weeks. Dr. Michael Worobey, head of the the University of Arizona's Department of Ecology and Evolutionary Biology and associate director at the BIO5 Institute, has written and researched pandemics worldwide. He agrees Arizona is on the edge right now. "We need to be preparing for a potentially very tough winter," Dr. Worobey said. While he says we need to take the possibility of a wave seriously in the next weeks, it should be done within context.
