Virus spreads to 18 people from one infected of Bf.7 variant, know how dangerous it is

There is also a risk of reinfection in the bf.7 variant. The R value i.e. reproduction number of this variant is 18. This means that corona can spread to 18 people by coming in contact with an infected patient of this variant.

in china corona virus The cases are increasing rapidly. The number of patients in hospitals is continuously increasing. Hundreds of people are losing their lives everyday. Omicron subs due to rise in Covid cases in China variant bf.7 is being considered. The infectivity rate of this variant is very high. According to doctors, all these variants omicron The most dangerous form of It also bypasses the immunity created by the vaccine. Corona in India too bf.7 4 cases of the variant have been reported.

There is also a risk of reinfection in the bf.7 variant. The R value i.e. reproduction number of this variant is 18. This means that corona can spread to 18 people by coming in contact with an infected patient of this variant. This is the reason why Kovid is spreading so fast in China. Every day cases are increasing at double the speed. However, it is not necessary that the ROR value of a variant should always be the same. It depends on what efforts are being made to control it in the area where the variant is spreading.

What is the reproduction value of other variants?

In this regard, Dr. Ajay Kumar says that the R value of other variants of Corona has been less than 5. The R value of Delta, the most dangerous variant that has come to India so far, was initially 1, after which it increased to 2, ie. An infected of Delta could transmit the virus to 3 people. During the second wave of Kovid, the R value of Delta was 3, but it did not exceed this. When the effect of the virus started decreasing, the R value decreased to less than 1. Apart from this, the R value of the alpha and lambda variants never exceeded one. These variants became weak within a few months.

No variant of Omicron has an R value greater than 5.

Dr. Kumar says that except Omicron’s bf.7 variant, the R value of any variant has not exceeded five. bf.7 is spreading rapidly because its reproduction number is high, but it is not necessary that an infected of this variant will transmit the virus to 18 people. It also depends on the immunity of the people coming in contact with the infected and whether they have had a natural infection before or not.
