Boston University researchers claim to have created a new COVID strain with an 80% kill rate. This is a result of similar experiments that were first believed to have caused the global pandemic in China.
According to the university, Omicron was combined with the original Wuhan virus, which killed 80% of infected mice. Mice only received Omicron exposure, and they had mild symptoms.
A team of scientists from Boston and Florida worked together to conduct the research at the school’s National Emerging Infectious Diseases Laboratories.
They took Omicron’s spike protein and linked it to the strain that was first identified during the outbreak of the pandemic. The researchers then recorded how the mice responded to the hybrid strain.
They wrote that Omicron causes mild, nonfatal infections in mice, but the Omicron S virus inflicts severe diseases with a death rate of 80 percent in mice.
Researchers found that the new strain contains five times as many infectious virus particles as the Omicron variant.
COVID-19 was first discovered to have originated from a Wuhan wet market. However, many believe that the virus was created at the Wuhan Institute of Virology. The World Health Organization is still being criticized for how it handled the crisis in its earliest, most crucial days.
Even if fully vaccinated, the Omicron variant can still be transmitted. Researchers believe that the spike protein is responsible for infectivity rates. However, other changes to the virus structure can also affect its timelines.
The study had one limitation: the type of mice used was not the best. Other types are closer to humans.
