A little more than two out of every three people who have mild or moderate cases of COVID-19 will go on to develop long-term symptoms. That's the troubling takeaway from a University of Arizona Health Sciences' study launched in May 2020. "This is a real wake-up call for anyone who has not been vaccinated," said lead researcher Melanie Bell, PhD, a professor of biostatistics in the Mel and Enid Zuckerman College of Public Health.

Data from a University of Arizona Health Sciences longitudinal study on COVID-19 shows that 67% of people with mild or moderate COVID-19 infection develop long COVID, with symptoms that last more than 30 days after a positive test.

Janko Nikolich-Žugich, MD, PhD, an immunologist and professor of medicine at the College of Medicine – Tucson, said recent findings from the CDC that vaccinated people who are infected with the delta variant could spread the virus just as easily as unvaccinated individuals should prompt behavioral changes across the board. “What we do not know at this point is whether the virus produced in vaccinated people is still at the same level of infectivity, or whether the presence of antibodies in these people may make the virus less infectious,” he said. “Until we learn about that, the delta variant behavior should mandate a change in strategies and approaches.”

The UArizona Center for Rural Health has received a five-year, multi-million dollar grant from state and federal sources to continue their mission of providing health care, education, technical assistance, data analyses and more to rural communities throughout the state.

As concerns grow over the highly contagious delta variant of the coronavirus, Germany on Monday became the largest Western country yet to announce that it will offer vaccine booster shots to a wide range of people considered potentially vulnerable. "The problem here is, we're just sort of going on immunological priors, rather than really great data to justify things one way or the other," said Deepta Bhattacharya, PhD, professor and immunologist at the College of Medicine – Tucson.
