First Omicron science

Viral replication is reduced in the lung tissue, but increased in the bronchi. This could indicate increased transmissibility but reduced pathogenicity. First video on my series on the respiratory system, HKUMed finds Omicron SARS-CoV-2 can infect faster and better than Delta in human bronchus #.Yb8Nai-l2QV First information on how Omicron SARS-CoV-2 infect human respiratory tract. Omicron infects and multiplies 70 times faster than the Delta in human bronchus, which may explain why Omicron may transmit faster Omicron infection in the lung is significantly lower than the original SARS-CoV-2, which may be an indicator of lower disease severity. This research is currently under peer review for publication. Pioneered the use of ex vivo cultures of the respiratory tract, for investigating many emerging virus infections since 2007
