“Researchers from the University of Hong Kong’s LKS Faculty of Medicine found that after 24 hours of infection, the omicron variant multiplied in the human bronchus 70 times faster than the delta variant and original coronavirus strain.

They also discovered that omicron infection in the lungs was “significantly lower” than the initial COVID-19 strain, “which may be an indicator of lower disease severity,” according to a statement from the university.

The strain replicated in human lung tissue at a rate that was more than 10 times lower than the original COVID-19 strain, which suggests that it may cause less-severe illness.”
