According to official sources here, Chinese cities are currently hit by the highly transmissible Omicron strain, mostly BF.7 which is the main variant spreading in Beijing and is contributing to a wider surge of Covid infections in that country.
”The BF.7’s high transmissibility in China might be attributed to a low level of immunity in the Chinese population from the previous infection and possibly vaccination too,” an official source said.
How infectious is new Omicron BF.7 sub-variant and its symptoms
While this hasn’t really created a big panic so far in India, the new Omicron variant is known to spread very fast.
BF.7 is a sub-lineage of the Omicron variant BA.5 and has the strongest infection ability since it is highly transmissible, has a shorter incubation period, and has a higher capacity to cause reinfection or infect even those vaccinated. A person infected with BF.7 variant can infect 10 to 18 people.
The BF.7 was first detected on October 4 in Yantai and Shaoguan city of China. BF.7 is an alias for B.1.1.529.5.2.1.7. It has already been detected in several other countries, including the US, the UK and European nations such as Belgium, Germany, France and Denmark.
