COVID 19 data compiled by the Arizona Department of Health Services is facing a new challenge over whether it truly reflects the percentage of positive tests. Percent positive is a key metric that’s now guiding decisions to reopen schools and businesses. The number for Arizona varies depending where you go to get the information. Dr. Joe Gerald, associate professor from the University of Arizona Mel and Enid Zuckerman College of Public Health, who tracks the spread of COVID-19 in Arizona, discusses the methodology behind the numbers.

According to one of the new studies, which has yet to be peer-reviewed and was posted on MedRxiv over the weekend, researchers at the University of Arizona conclude that "immunity is durable for at least several months after SARS-CoV-2 infection." Deepta Bhattacharya, associate professor of immunobiology at the College of Medicine – Tucson said that he and his colleagues came to their conclusion after they measured antibodies and examined how long they were being produced in COVID-19 patients.

Disease-fighting antibodies, as well as immune cells called B cells and T cells that are capable of recognizing the virus, appear to persist months after infections have resolved – an encouraging echo of the body's enduring response to other viruses. “Things are really working as they're supposed to,” said Deepta Bhattacharya, an immunologist at the University of Arizona College of Medicine – Tucson.

The number of weekly COVID-19 deaths in Arizona recently hit a high-water mark. It’s one of the latest and most concrete signs that the pandemic is getting better statewide, although the virus still presents a significant risk. “For the first time I’m confident that we’ve had a peak in deaths,” said Joe Gerald, an associate professor with the University of Arizona’s Mel and Enid Zuckerman College of Public Health. “Things are getting markedly better. That's awesome.”
