Chinese scientists are experimenting with a deadly virus that that has a 100 per cent kill streak in mice. The fatal virus, dubbed GX_P2V in a study published on bioRxiv, targeted the brains of mice whose genetic composition was designed to resemble that of humans. The researchers found that the mice lost significant weight within five days of infection, became lethargic, and their eyes turned white. They died just eight days after being infected, the researchers further wrote in the study.

The scientists expressed surprise at the rapid death rate.

“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 researchers wrote.
