Virus with 100% kill rate turns eyes white

- NEWS.COM.AU

CHINESE scientists are experiment­ing with a virus related to COVID-19 that has a 100 per cent kill streak in “humanised” mice.

The deadly SARS-CoV-2-related pangolin coronaviru­s— known as GX_P2V — attacked the brains of mice that were engineered to reflect similar genetic makeup 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.

The deadly virus is a mutated version of GX/2017, a coronaviru­s cousin that was reportedly discovered in Malaysian pangolins in 2017 — three years before the pandemic, the New York Post reports.

All the mice that were infected with the virus died within just eight days, which researcher­s noted was a “surprising­ly” rapid death rate.

GX_P2V had infected the lungs, bones, eyes, tracheas and brains of the dead mice, the last of which was severe enough to ultimately cause the death of the animals.

In the days before their deaths, the mice had quickly lost weight, exhibited a hunched posture and moved extremely sluggishly.

Most eerie of all, their eyes turned completely white the day before they died.

Although terrifying, the study is the first of its kind to report a 100 per cent mortality rate in mice infected by the COVID-19 related virus — far surpassing previously reported results from another study, the researcher­s wrote.

More importantl­y, the results of the study do not clearly indicate

how it would impact human beings.

Francois Balloux, an epidemiolo­gy expert at the University College London’s Genetics Institute, slammed the research as “terrible” and “scientific­ally totally pointless.”

“I can see nothing of vague interest that could be learned from force-infecting a weird breed of humanised mice with a random virus. Conversely, I could see how such stuff might go wrong,” the professor wrote on X.

“The preprint does not specify the biosafety level and biosafety precaution­s used for the research,” he continued.

“The absence of this informatio­n raises the concerning possibilit­y that part or all of this research, like the research in Wuhan in 2016-2019 that likely caused the COVID-19 pandemic, recklessly was performed without the minimal biosafety containmen­t and practices essential for research with a potential pandemic pathogens.”
