Covid-19: India is also at risk from the BF.7 variant causing havoc in China? Know everything from its infectivity to seriousness

China is going through a severe infection of Corona these days. After the relaxation given in the zero-covid protocol, the situation has worsened here, the situation is that there is a huge crowd of infected people in the hospitals, surprisingly the death toll from corona is also increasing. On Monday, China confirmed the first death in this wave of infection, although global agencies allege that the authorities are hiding the death toll. According to another media report, huge rush is being seen in the mortuaries in Beijing city of China, which has the highest number of deaths due to Kovid-19.

The increasing cases of corona in China are a warning to other countries as well. US officials said in media reports – We are hoping that China will update about this soon, so that other countries can also be alerted. We know that the virus can spread very fast and if we do not take preventive measures then it can become a threat to other countries as well.

At present, all countries need to consider their strategy regarding Kovid-19, we have to avoid the mistake of China, taking the epidemic lightly can lead to such a serious situation.

Health experts said that the Omicron BF.7 sub-variant is being seen as the main reason for the current increase in cases in China. The danger of this variant can also be in India. In October, the Gujarat Biotechnology Research Center confirmed the first case of infection due to this variant in the country. Apart from India, infection due to this variant has also been confirmed in many European countries.

Health experts say that it is being seen as a very challenging variant in the studies, so everyone needs to take special precautions.

Regarding the risk of corona in India, Dr. NK Arora, Chairman, National Technical Advisory Group on Vaccination (NTAGI), says, there are reports of widespread covid infection in China. As far as its danger is concerned in India, people have been vaccinated on a large scale here, due to which the risk of infection is very low.

INSACOG data shows that almost all sub-variants of Omicron found worldwide have been observed in India. At present, we are closely monitoring the situation, but there is no need to panic as the situation in India is under control.

Know about the BF.7 variant

The researchers found that BF.7 is a mutated form of Omicron’s BA. sub-variant, although some mutations appear to increase infectivity and severity. Reports from China indicate that BF.7 may be more virulent than other subvariants of Omicron. Its equalization period is also very less.

Incubation period means the time it takes for symptoms to appear in a person infected with the virus. Apart from this, the ability to dodge immunity is also being seen more in BF.7, in such a situation it is a variant that increases the difficulties of vaccinated people.

Infection can increase rapidly

Based on the study, the researchers said that the reproduction rate (R0) of BF.7 is also high, which means that its infectivity can be very high. While the reproduction rate in the case of delta variant was seen between 5-6, in the case of BF.7 it has increased to close to 10-18.

This means that an infected person can transmit the virus to an average of 10 to 18 other people. Omicron has an average R0 of 5.08. In view of this danger, health experts say that all countries need to be strict again to prevent Kovid-19.

There is also a risk of hidden spread

The researchers pointed out that the BF.7 sub-variant may also be at risk of hidden spread. Hidden spread means that most people infected with it do not show symptoms, in which case their identification becomes difficult. Nevertheless, there may be a risk of spreading the virus from such people, since BF.7 also has a high reproduction rate, so it can be a variant that can cause infection in a large population in a short time.

Most of the symptoms of BF.7 are similar to the earlier variants, but its infectivity rate can be quite worrying.
