Experts say that unlike the COVID-19 spikes in the U.S. in the spring and summer, which hit hardest in the Northeast and the Sun Belt, respectively, the current surge is happening nationwide: COVID-19 cases are currently rising in almost every state. "What we're seeing right now is not only worrisome with such widespread transmission and high case counts," said Saskia Popescu, an epidemiologist at the University of Arizona and a member of the Federation of American Scientists' Coronavirus Task Force. "But with impending holidays, likely travel, and people moving indoors due to colder weather, I'm increasingly concerned that this will be a rather steep and long third wave."

Dr. Kelly Reynolds, an environmental microbiologist in the Mel and Enid Zuckerman College of Public Health at the University of Arizona, acknowledged that more lockdowns are probably coming in the weeks and months ahead, citing curfews in Europe and a voluntary stay-at-home order in El Paso, Texas. The good news, she added, is that mortality rates are lower now than they were in the spring, indicating doctors have gotten better at treating the virus and that communities are less likely to “get into danger zones where hospitals get overrun.”

Dr. Elaine Situ-LaCasse, an associate professor and emergency ultrasound faculty at the University of Arizona College of Medicine – Phoenix, is leading a study to design an educational program teaching rural health care professionals about the use of lung ultrasound technology remotely.

The goal of reaching immunity for COVID has been intensely debated and we have new research on antibodies to throw into the mix. Dr. Deepta Bhattacharya, an immunobiologist and The Today Show - Hoda/Jenna associate professor and at the University of Arizona College of Medicine in Tucson, talks about his recent study published in the journal Immunity, to determine whether people who are infected are immune from reinfection and, if so, for how long.

Our sudden surge of winter weather is hitting the high country really hard. Some folks woke up to a foot of snow this morning. "When you have that big of a change in temperature, that drastic change, it means the body also has to adjust itself more quickly than normal," said Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix.

Antibodies that may protect against COVID-19 in people who have previously had the virus declined over the summer, according to a new study that could throw doubt on the idea that a population can develop herd immunity. A University of Arizona Health Sciences Study that examined a sample of nearly 6,000 COVID-19 patients, showed that antibodies persist for months after infection, providing long-term immunity. “We clearly see high-quality antibodies still being produced five to seven months after SARS-CoV-2 infection,” said Deepta Bhattacharya, associate professor of immunobiology, at University of Arizona College of Medicine.

A new study from University of Arizona Health Sciences found that SARS-CoV-2 (the virus which causes COVID-19) may actually have a pain-diminishing effect on those it infects, particularly in the initial phase of infection. Dr. Rajesh Khanna, lead author and professor of pharmacology at the University of Arizona College of Medicine, talks about his research recently published in the journal PAIN.

Here is what you can do to make sure you and other trick-or-treaters stay safe from COVID-19 this Halloween. Like all things in 2020, Halloween festivities may be a little different this year. To help keep you safe on the spookiest of holidays, 12 News spoke to University of Arizona’s College of Medicine Associate Professor Dr. Shad Marvasti.

Ginny Clements donated $8.5 million to the University of Arizona Cancer Center to endow the Ginny L. Clements Breast Cancer Research Institute and to support a director’s chair, two professorships, and other programs. Clements co-founded Golden Eagle Distributors, a Tucson distributor of Anheuser-Busch products, with her late husband Bill Clements, who died in 1995. She retired in 2003. Clements is a breast-cancer survivor who was diagnosed with the disease at age 15.

Scott Sherman, MD, PhD, and Torsten Falk, PhD, both associate professors at the University of Arizona College of Medicine and authors of the previous studies, are currently working with the university’s Tech Launch Arizona to patent the findings.
