The “pseudovirus” — which can’t infect humans — will be used to understand how well antibodies produced by the COVID-19 vaccines can fight off the variant. Deepta Bhattacharya, PhD, a professor of immunobiology at the College of Medicine – Tucson, is interviewed.

Now that the COVID variant Omicron is confirmed in the U.S., questions are arising around the role of the travel ban. This as new details are emerging about a new travel requirement government leaders are now considering. Joe Gerald, MD, PhD, associate professor and director of the public health policy and management program at the Mel and Enid Zuckerman College of Public Health, says to make the travel restrictions more effective he thinks we should also be doing testing, quarantining and isolation.

Childhood autism rates are at the highest level since the CDC began tracking the disorder in 2000. The increase likely reflects improvements in diagnosis and identification, not an increase in incidence. Sydney Pettygrove, PhD, associate research professor and epidemiologist at the Mel and Enid Zuckerman College of Public Health, and a principal investigator for the Autism and Developmental Disabilities Monitoring site in Arizona, is quoted.

Pandemic-related changes helped provide a continuum of care, while also reducing clinic “no-shows.”

Allison J. Huff, DHEd, assistant professor in the Department of Family and Community Medicine at the College of Medicine – Tucson, is involved in a clinical trial using artificial intelligence technology that analyzes a patient’s words, voice, and facial expressions to detect mental health conditions and integrates with telehealth services.
