Cleveland Clinic and Case Western Reserve University’s New Research Says COVID-19 Variants May be Less Severe than Original Virus Strains by TrialSite Staff for Trial Site News
Research Details
Scientists from both Northeast Ohio institutions tracked genome sequences for SARS-CoV-2 between March 11-April 22, 2020, recently found that clades, which are subgroups of an initial strain, were associated with a higher mortality rate than those of newer origin.
This group of researchers, led by Dr. Frank Esper, a pediatric infectious disease physician at Cleveland Clinic Children’s, also included scientists who study cancer genomics, computer and data sciences, neurology and pathology, including Dr. Brian Rubin, chair of Cleveland Clinic’s Robert J. Tomsich Pathology and Laboratory Medicine Institute, and Jing Li, Ph.D., the Leonard Case Jr. Professor in Case Western Reserve University’s Department of Computer and Data Sciences.
“This study offers a detailed description of how the different COVID-19 clades evolved and competed once they were brought to Cleveland,” said Dr. Rubin. “The linkage of viral clades to outcomes is quite important and highlights the importance of viral genome sequencing to gain a deeper understanding of new diseases.”

The team analyzed RNA sequences from the bloodwork of more than 302 patients who contracted COVID-19 in Northeast Ohio within the first month of the pandemic.
