Arizona reported a record 10,322 new COVID-19 cases Tuesday, more than twice the previous high, as cases surged ahead of a holiday season that one health expert said could be a "real scary time." Dr. Daniel Derksen, an associate vice president at the University of Arizona Health Sciences, said the holiday trips that many people took this weekend put the state in a dire circumstance in regard to the number of hospital beds.

Tanning beds and sunbathing may be linked to a greater risk of developing endometriosis, according to a new study. Leslie Farland, an assistant professor at the University of Arizona College of Public Health and the leader of the research, said the association between endometriosis and melanoma may reflect a common genetic background or an underlying association between sun exposure and risk of endometriosis.

E-training helped massage therapists increase their knowledge of skin cancer and become more comfortable discussing risk reduction with clients.

A researcher at the University of Arizona cautioned Monday that the state will be faced with a dire coronavirus situation within four weeks if no further action is taken to slow the spread of the virus. Dr. Joe Gerald, a member of the university’s COVID Modeling Team, told KTAR News 92.3 FM’s Gaydos and Chad a “storm is coming” without additional guidance and mitigation strategies.

U.S. Sen.-elect Mark Kelly writes that the lack of a national strategy is hurting our coronavirus response and recovery. "Dr. Joe Gerald, a member of my transition team and a researcher at the University of Arizona who has been analyzing COVID-19 data, described how cases are rising quickly and that our health-care system could soon be struggling to keep up, just like it did last summer," Kelly writes.

A team of university researchers says a statewide shelter-in-place order could help avert a "catastrophe" in Arizona hospitals. "It has now reached a point to where we are truly in a crisis here in Arizona. The sooner we intervene the better off we will be. Every day of delay will result in needless hospital admissions and ultimately, what we also care about — deaths," Joe Gerald, UA public health researcher and COVID-19 modeling team leader.

The health officials in charge of making models, or predictions, as to where the virus is spreading are painting a dire warning about the holidays. “If something is not done quickly, we worry that this outbreak will overwhelm our hospital system by the end of December,” said Joe Gerald, PhD, an Associate Professor of Public Health at the University of Arizona. “We’re very worried that his is a very vulnerable period.”

With more than 1 million travelers dispersing across the country in one day, health experts are asking those who gathered with people outside their households over Thanksgiving week to get tested for Covid-19. Arizona's test positivity on Monday was almost 20%. If officials there don't address the rise in cases in the next few weeks, the state will suffer hundreds of preventable deaths, the University of Arizona's Zuckerman College of Public Health said in a report Friday.

University of Arizona Heath Sciences researchers developed one of the most accurate COVID-19 antibody tests available and now have shown antibodies persist for months after infection, providing long-term immunity.
