In a Wuhan-esque study, Chinese scientists are experimenting with a mutant COVID-19 strain that is 100% lethal to “humanized” mice. The deadly virus — known as GX_P2V — attacked the brains of mice that were engineered to reflect genetic makeup similar to people, according to a study shared last week out of Beijing. “This underscores a spillover risk of GX_P2V into humans and provides a unique model for understanding the pathogenic mechanisms of SARS-CoV-2-related viruses,” the authors wrote.
