New Omicron Subvariant BF.7: Know About Its Symptoms, And Severity

Omicron BF.7

ABOUT NEW VARIANT OMICRON

Because it is highly transmissible, has a significantly shorter period of incubation, and has a higher probability of causing reinfection or affecting even vaccinated individuals, BF.7, a sub-lineage of the Omicron variant BA.5, has the strongest infection capability.

Omicron Subvariant BF.7 Cases In India

At the Gujarat Biotechnology Research Centre, the first case of this highly infectious strain was discovered earlier in October. India currently has four cases, with three occurring in Gujarat and one in Odisha. The three Omicron BF.7 cases were reported to the Gujarat state health department between July and November of this year. The three patients were treated in isolation at home and recovered completely. This patient has been treated for a case found earlier this year in Odisha.

But so far, it hasn’t caused a frenzy wave. The recently discovered Omicron subvariant BF.7 is known to spread quickly and has a short hatching period. It has been predicted that within the next three months, this variant will infect approximately 60% of China’s population. The BF.7 subvariant is rapidly disseminating in Beijing and contributing to a large increase in the number of infections in China.

Additionally, Omicron sub-variation BF.7 is accounted for in a few different nations, including the US, UK, and European countries like Belgium, Germany, France, and Denmark.

Know About Its Symptoms, And Severity

The two Omicron subvariants, BA.1 and BA.2, evolved. Other variants of BA.2 exist, including BA.4, BA.5, and BA.2.75. Furthermore, BF.7 is a progression of BA.4/5 and is currently experiencing a significant rise in China.

The World Health Organization’s bulletin on the global COVID-19 situation, which came out last week on December 14, only mentioned five “relevant” sub-variants. It did not mention BF.7, so there is no mention of its ability to evade neutralization. Except for China, the BF.7 has remained virtually unchanged everywhere it has evolved.

SYMPTOMS

Similar to other Omicron variants, an infection with the BF.7 subvariant will cause fever, fatigue, and upper respiratory symptoms like a sore throat and a runny nose.

In a few instances, patients experienced vomiting and diarrhea as gastrointestinal symptoms. Additionally, when the BF.7 subvariant is present, individuals with weakened immune systems may develop severe illness.

Which mutations result in BF.7?

The BF.7 subvariant was created by a specific mutation, R346T, in the spike protein of SARS-CoV-2. In addition, BF displays this mutation. The “parent” variant of 7 known as BA.5 has been linked to an increase in the COVID-19 virus’s capacity to evade vaccine-derived neutralizing antibodies or previous Coronavirus infection.

The study, which was published in the journal Cell Host & Microbe in November of this year, found that BF.7 is more resistant to neutralization. The neutralization of BF.7 in the sera of triple-vaccinated healthcare workers and Omicron BA.1 and BA.5-affected patients was the focus of the study. Sera is the liquid portion of the removed blood proteins and clotting factor. The most significant cause of BF.7’s increased neutralization resistance is the N460K mutation.

The Omicron subvariant remains constant in other parts of the world, despite the immune-evasive characteristics of BF.7 and alarming signs of its progression in China. For the period up to December 10, BF.7 is anticipated to account for 5.7% of infections in the United States.

What preventative measures should be taken?

We are all aware of the appropriate COVID-19 behavior guidelines, but only a few people should follow them. People have been urged by the government to follow the COVID guidelines and get vaccinated. When it comes to public places, seniors and people who have other conditions should take extra precautions. Getting vaccinated and continuing to take preventative measures to stop the virus from spreading—such as wearing masks, avoiding social contact, frequently washing hands with soap and water, or using hand sanitizer—are both essential.

The government has resumed random Coronavirus testing of international passengers at all national airports beginning on Wednesday as a precaution.
