Researchers investigate virus transmission
Household transmission

University of Arizona Health Sciences researchers will evaluate factors affecting the secondary transmission of COVID-19 and influenza within households during the Arizona Household Virus Study, part of the Centers for Disease Control and Prevention’s Respiratory Virus Transmission Network.
According to the CDC, the Respiratory Virus Transmission Network is designed to estimate whether vaccines reduce transmission of influenza and COVID-19 within households.
“The Arizona Household Virus Study will contribute to the national picture of household transmission of COVID-19 and influenza,” Kate Ellingson, PhD, assistant research professor in the UArizona Mel and Enid Zuckerman College of Public Health said. “It will help us understand transmission rates in households as well as risk factors that influence transmission, such as household size, composition and vaccination status.”
Dr. Ellingson and Karen Lutrick, PhD, assistant professor in the UArizona College of Medicine – Tucson’s Department of Family and Community Medicine , are leading the Arizona Household Virus Study, which runs through June 2023. The study will look at the drivers of household transmission including virus characteristics, vaccination status, and the influence of physical and behavioral factors.
Community members are eligible to participate if they have tested positive for COVID-19 or influenza within the last six days, currently live with someone who is not yet sick for at least 10 days prior to and after a COVID infection and are able to read English or Spanish. Participants and other members of their household will complete at-home PCR tests, record daily symptoms and activities, and may be asked to provide blood samples for further testing.
Southern Arizona was selected as a regional site because of the region’s diverse population and high percentage of multigenerational families living in a single household.
“Dr. Ellingson and Dr. Lutrick are the ideal researchers to lead the Arizona portion of this vital national CDC study,” Iman Hakim, MD, Dean of the Zuckerman College of Public Health said. “They bring experience and expertise to the job, including current experience working on COVID-19 research with the CDC.”
