Though it causes less severe disease than the Delta variant, the highly transmissible Omicron SARS-CoV-2 variant has been twice as deadly in unvaccinated people and has therefore hit rural Americans harder than those living in cities, a study today in Frontiers in Medicine finds.Because low-vaccination parts of the country are mostly rural, those living in less densely populated areas continue to bear the highest COVID-19 burden, according to the study authors, who hail from universities in four US states and Zimbabwe.
They worry that rural America will face a disproportionate long-term impact from lingering symptoms known as long COVID."We're talking about an extra burden that rural counties face.
They face a higher probability of developing chronic illness from long COVID," said co-author Claudia Moreno, PhD, assistant professor of physiology and biophysics at the University of Washington, in a University of Cincinnati news release.Rural-versus-urban disparitiesFor the cross-sectional study, the researchers analyzed data on COVID-19 cases and deaths, as well as vaccination status, in 2,417 counties from Dec 1, 2021, to Jan.
