The new man-made COVID strain has five times more infectious virus particles than the Omicron variant, the researchers said.
New Deadly COVID Strain
The team, from Florida and Boston at the school’s National Emerging Infectious Diseases Laboratories, extracted the spike protein from Omicron and attached it with the strain first detected at the onset of the pandemic that began in China’s Wuhan.
Omicron Variant of COVID-19
Omicron variant is a mutated strain of coronavirus (SARS-CoV-2) with faster transmissibility and enhanced virulence compared to the original COVID-19 virus.

‘In mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80 percent.’
They then documented how the mice reacted to the hybrid strain. It is to be noted that the mice were given large doses of the virus and the lungs of the mice are far more sensitive. The mouse mortality rate of 80 percent is far higher than the human mortality rate of less than 1 percent from the original SARS-CoV-2 variant. In a statement, the university stressed that the replicated strain was less dangerous than the original strain.

Test your Knowledge on Coronavirus (COVID-19)
Coronavirus is a large positive-strand RNA virus that is surrounded by a protein envelope. The virus obtains its name from the S protein spikes on its surface, which resemble a crown. The overall pattern of increasing coronavirus cases is shown to spike up with the “second wave” of COVID-19.
With spiking effects of the second wave of coronavirus, the best way to keep it at bay is to follow COVID-appropriate safety practices like wearing a mask, regularly cleaning your hands, and coughing into a bent elbow or tissue along with physical distancing (6 feet about 2 arm's length), that may help evade the severity of COVID-19 infection.

Why COVID-19 is More Deadly in Obese People and Men?
What makes individuals more vulnerable to COVID-19? The new study suggests obesity and biological sex may impair the ability to fight off COVID-19.

Long COVID-19 Haulers Should Take Precaution in Polluted Air
Exposure to air pollution increases the likelihood of hospitalization by 30% in people who suffer from long COVID-19.
