U of T researchers unveil new preclinical insights into why males are more likely to have severe COVID-19
A new study from a team of EPIC members has uncovered the biological reasons underlying sex differences in COVID-19 outcomes and is offering a promising new strategy to prevent illness. Early on during the pandemic, clinicians quickly noticed that males were more likely than females to be hospitalized or admitted to the ICU or to die from COVID-19 despite having similar infection rates. This pattern held true across all age groups and in countries around the world. The research, conducted in mice and published in the journal iScience, points to the ACE2 protein as a key contributor to differences in COVID-19 outcomes between males and females.
Study identifies new SARS-CoV-2 variant in white-tailed deer and first evidence of deer-to-human transmission
A team of researchers led by EPIC member Samira Mubareka has characterized a new, highly divergent variant of SARS-CoV-2 in Ontario white-tailed deer. They also found the first evidence of deer-to-human transmission.
