Beijing’s main strain of the current outbreak, BF.7, is the most infectious to date

According to the Beijing Daily News, Dr. Li Dong, chief physician of the Department of Respiratory and Infectious Diseases at Beijing Youan Hospital, said that the main strain of the current outbreak in Beijing is the Omicron variant BF.7.

As one of the Omicron mutant strains, BF.7 is highly infectious, with the R0 (viral transmission index) of Delta mutant strains being 5-6 and Omicron mutant strains exceeding 10.

And the Omicron variant is more immune escape and able to multiply in the upper respiratory tract, these mean that the infected person is able to infect more cases by talking and coughing, and people around are more likely to catch it, and the Omicron is more mild and less vigilant.

Even when compared to other variant strains of Omicron, for example, compared to BA.1, BA.2 and BA.5 variant strains, BF.7 is faster and more transmissible, and is the most transmissible of the Omicron variant strains currently circulating in the country.

In addition, Omicron can be detoxified in 1 day after infection, and second generation cases may appear in 2-3 days. (Beijing Daily)
