New Study: Omicron is 4x more contagious than Delta and effectively bypasses existing immunity
Hiroshi Nishiura, a professor at Kyoto University who specializes in mathematical modeling of infectious diseases, analyzed the Omicron genome data that became available late last month, sourced from the province of California in South Africa.
"It’s much better at evading immunity gained through previous infection or vaccination"
"Omicron is more contagious and does a better job of dodging immunity from prior infection or vaccines," noted Nishiura, who presented his findings this Wednesday during a Scientific Advisory Council meeting for the U.S. Department of Health.
The World Health Organization (WHO) has warned that Omicron could trigger a surge in new infections "with severe consequences."
Bloomberg reports that this latest analysis used the exact same methodology applied back in July—research which was published in the medical journal CDC. Back then, Nishiura predicted the dominance of the Delta strain just before the Olympic Games in Tokyo.
Hundreds of scientists globally are currently researching this new variant, which stands out as the most distinct among the five variants that the WHO has labeled as "concerning."
Infection numbers in South Africa have skyrocketed to nearly 20,000 daily since the country first reported discovering Omicron two weeks ago. Before this discovery, case numbers in that country remained relatively low, despite only 26% of the population being fully vaccinated against COVID-19.

How exactly do researchers use mathematical modeling and viral genome analysis to determine how virulent and pathogenic a virus actually is? It's like trying to predict a storm's path by looking at tiny changes in wind patterns!
