Omicron BA.2 subvariant likely to spread globally: WHO

According to the World Health Organization, the BA.2 subvariant of Omicron is likely to spread globally, although it is not clear whether it will cause reinfection in people infected with the original Omicron strain.

CNBC reported that the ba.2 subvariant, which is currently more contagious than the dominant ba.1 variant, will become more common, according to Maria Van Kerkhove, the WHO’s Covid-19 technical lead.

Van Kerkov a question the live stream on social media platforms to WHO on Tuesday and during the session, “BA 2 BA 0.1 is more permeable than that, so we see growing throughout the BA 0.2 world look forward to. “

WHO is monitoring BA.2 to see if the subvariant causes an increase in new infections in countries that saw a rapid increase and then a sharp decline in omicron cases, van Kerkhove said.

He said that although research is still ongoing, there is no indication of a difference in the severity of infections caused by either of the two.

However Omaikron rapidly spreads, it causes mild infections than variants Alpha and Delta.

Researchers in Denmark have found that BA.2 is about 1.5 times more transmissible than BA.1 and is more efficient at infecting people who have been vaccinated and even enhanced. However, people who are fully vaccinated are less likely to spread it than uninfected people.

Van Kerkhove said vaccines are highly effective in preventing serious illness and death, although they do not prevent all infections. He called upon people to get vaccinated and wear masks indoors.

The report said the WHO’s covid event manager, Dr. Abdi Mahmood, said it was unclear whether BA.2 could re-infect people who previously had BA.1.

This information could have a significant impact on how far the virus can spread. A study in the UK found that two-thirds of people who caught Omicron said they had covid before.
