American scientists have created a new strain of coronavirus: it kills 80% of those infected

Boston University researchers say they have developed a new strain of COVID that has an 80% mortality rate after a series of similar experiments that were first thought to have started a global pandemic that started in China. FoxNews.

The variant, which is a combination of omicrons and the original Wuhan virus, killed 80% of the mice it infected, according to the university. When mice were exposed to omicron alone, they experienced mild symptoms.

The study was conducted by a team of scientists from Florida and Boston at the National Emerging Infectious Diseases Laboratory.

They extracted a spike protein from omicrons and attached to it a strain first discovered at the start of the pandemic that began in Wuhan, China. They then documented how the mice responded to the hybrid strain.

"In mice, while omicron causes a mild, non-fatal infection, the omicron S-carrying virus causes severe disease with an 80 percent mortality rate," they wrote in the research paper.

The new strain contains five times more infectious viral particles than the omicron variant, the researchers said.

The university's statement emphasizes that the replicated strain is less dangerous than the original strain.

“First, this study is not a gain-of-function study, meaning it did not strengthen the strain of the SARS-COV-2 virus or make it more dangerous. In fact, this research has made virus replication less dangerous,” the statement said. “Secondly, the study was reviewed and approved by the Institutional Biosafety Committee (IBC), which includes scientists as well as community members. The Boston Public Health Commission also approved the study. Additionally, this study reflects and reinforces the results of other similar studies conducted by other organizations, including the FDA. Ultimately, this research will benefit society by leading to improved targeted therapeutic interventions to help combat future pandemics.”

At first, COVID-19 was thought to have come from a market in Wuhan, although many believe the virus was created at the Wuhan Institute of Virology. The World Health Organization continues to face criticism for how it handled the crisis in its first, most important days.

The omicron variant is highly contagious, even in those who are fully vaccinated. The spike protein is responsible for the level of infectivity, according to the researchers, other changes in the structure of the virus determine its lethality.
