SARS-CoV-2, the virus that causes COVID-19, can relieve pain, according to a new study by University of Arizona Health Sciences researchers. The finding may explain why nearly half of all people who get COVID-19 experience few or no symptoms, even though they are able to spread the disease, according to the study's corresponding author Rajesh Khanna, a professor in the UArizona College of Medicine – Tucson's Department of Pharmacology.

The Centers for Disease Control is warning Americans to stay home during the holidays, after more than 250,000 people have died from COVID-19. In Arizona, the virus is surging. Thursday the Arizona Department of Public Health reported more than 4,100 new cases which is the highest number of cases in one day since mid-July. Modeling from both the ASU Biodesign Institute and the University of Arizona Mel and Enid Zuckerman College of Public Health warn of dire days ahead if current COVID-19 trends remain constant.

Health experts say that if you do need to travel, they recommend that you wear both a face mask and a face shield. You should sanitize frequently and get tested for the coronavirus before you visit with others outside your household. "If there's any possibility of limiting contact with others and limiting it to outdoors as opposed to indoors, all these things would be preferable," said Dr. Shad Marvasti, an associate professor at the University of Arizona College of Medicine.

Arizona's largest health care system is reinstating visitor restrictions due to exponential increases in COVID-19 cases that could soon overwhelm hospitals across the state. Effective 6 p.m. If the rise of coronavirus transmission in Arizona is not quickly addressed, new COVID-19 cases "will overwhelm our capacity to provide optimal hospital care within a matter of weeks," according to a Nov. 18 report by Joe Gerald, an associate professor at the University of Arizona's Mel and Enid Zuckerman College of Public Health who has been tracking the pandemic’s spread in Arizona for months.

Research at the College of Nursing brings a unique perspective to advancing health and healthy equity.

Arizona public health officials are readying for a rollout of a COVID-19 vaccine in the coming months, but data by health researchers on flu vaccinations suggests that Arizonans might opt not to seek out the vaccination. "Every state has different layers of challenges," said Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix and a physician who has specialized in chronic diseases. "I think the Arizona culture is such that there is more questioning of vaccines."

Arizona was in the bottom tier in three of six categories in a new American Lung Association report, which put the state dead-last for the number of patients who receive treatment after getting a diagnosis of lung cancer. Dr. Dan Derksen, associate vice president for Health Equity, Outreach & Interprofessional Activities at the University of Arizona Health Sciences, said that improvements in lung cancer have made the disease less of a “death sentence,” but the key remains screening for the disease to reduce mortality.

Another at-home COVID-19 test has received FDA authorization, joining hundreds of other at-home tests that have circulated since the pandemic began. Public health experts warn some of them may not be legitimate. Dr. Shad Marvasti, director of Public Health and Prevention at the University of Arizona College of Medicine in Phoenix, is encouraged by the new test. He says accessibility to tests that can deliver rapid results will help people stop the spread of COVID-19. But he is encouraging consumers to do their homework before using any at-home test, even if it's been approved by the FDA.
