Omicron BF 7 - All You Need To Know

Introduction

COVID-19 infection is always surprising, with newer variants every few months. Omicron BF 7 is the recent subvariant of the Omicron variant. Many countries are under threat from this new subvariant. It was first detected in inner Mongolia of northwest China on October 4th. BF 7 and BA. 5.1.7 are causing a surge in COVID cases in China. It has also been detected in the United States, the United Kingdom, Australia, and Belgium. Gujarat Biotechnology Research Center in India has been detected with a case of Omicron BF 7. It may be a dangerous outbreak during this Diwali.

What Is Omicron BF 7?

The Omicron variant of COVID-19 (coronavirus disease) was first identified in South Africa on November 24th, 2021. This variant was a concern because it was highly contagious and had a high mutation rate and transmissibility. However, the Omicron variant had milder symptoms. Omicron BF 7 and BA.5.1.7 are the new sub-variants of Omicron.

The BF 7 variant is also referred to as “ Omicron spawn.” It poses a new threat because it dodges the antibodies created for its earlier versions and surpasses the immunity gained from previous infections and vaccinations. It is also known as the immune escape variant, evading immunity. BF. 7 is the name given to downstream descendants of BA. 5. BF 7 can mutate fast. The mutations began with BA.1, and at present, they have chronicled BF 7.

How Dangerous Is Omicron BF 7?

It is known that any mutant virus variant has an advantage over the wild-type virus. Omicron BF 7 is immunologically evasive, fast-mutating, and more virulent. It can counter the antibodies acquired from previous infections and vaccinations. This variant has a better binding ability. Hence, a few viral particles are sufficient to cause BF 7 infection. It has increased transmissibility because it evades immunity.

What Are the Symptoms of Omicron BF 7?

The globally reported symptoms of Omicron BF 7 include the following:

• Continuous coughing.

• Sore throat.

• Congestion.

• Runny nose.

• Difficulty in hearing.

• Chest pain.

• Shaking or quivering.

• Changes in the sense of smell.

• Body pain.

• Fatigue.

Why Is Omicron BF 7 Concerning?

It is a big concern because of its greater transmissibility, and BF 7 has already been detected in India. However, according to health experts and scientists, it is not a big threat because BF 7 is from the Omicron family. Omicron had a high transmissible rate but did not create havoc in India.

The Omicron variant is continuously evolving, but global initiatives on sharing avian influenza data (GISAID) from India showed that no sequence is available for the BF. 5.1.7 variant from the data submitted to Gujarat biotechnology research center. Therefore, according to a senior scientist at ICMR (Indian Council of Medical Research), cases are present in India, but it is not a panic situation. However, it is essential to maintain social distance and follow preventive strategies to prevent the potential spread.

Why Is Omicron BF 7 an Immune Evasive Variant?

Omicron has been mutating ever since it arrived. The mutation started as BA 1 and reached BF 7. The receptor binding domain (RBD) of the virus's spike protein is responsible for the mutations. The virus uses the receptor binding domain of the spike protein to attach to human cells. The new sub-variant can escape immune responses from vaccination or infections, with its convergent evolution involving about five frequent mutations. Hence, it is referred to as an immune evasive variant.

Will Diwali Trigger a Fresh Wave?

Every new variant and subvariant of COVID stalks the vulnerable individual and puts them at risk. A new variant always increases the chance of spread. According to health experts, there is a chance for a new wave with the emerging BF 7 variant. Diwali is the biggest festival in India. 2022’s Diwali is in full swing as people gather in huge numbers from different locations, violating social distancing and protection norms. Omicron BF 7, an immunologically evasive variant with highly potent transmissibility, may trigger a new wave. As the flu and winter season are forthcoming, cases of sore throat, congestion, and runny nose will likely increase.

What Are the Preventive Strategies?

Individuals should not panic about this new subvariant but should be careful and take necessary precautions. As the festival season is approaching, the following precautions should be followed to prevent the spread:

• Maintain social distancing everywhere, even at home.

• Wear a proper, well-fitting face mask that covers the mouth and nose.

• Personal hygiene and coughing into bent elbows or tissues should be followed.

• Wash hands with soap and water to maintain hand hygiene.

• Proper ventilation should be maintained through open windows.

• Vaccination and booster doses should be in place.

• Keep an eye out for infection signs, and if there are any symptoms, get medical help immediately.

Who Is at a Higher Risk of Contracting the Omicron Bf. 7 Variant Infection?

Unvaccinated individuals are at a higher risk. Individuals with compromised immune systems, including youngsters, the elderly, pregnant women, and those with many underlying health conditions such as uncontrolled diabetes, cancer, renal disease, or heart disease, have a higher likelihood of developing this illness. It is advisable for individuals to strictly follow Covid-appropriate behavior and receive the COVID-19 vaccination as a preventive step.

What Is the Update on Omicron BF 7 Research?

Omicron BF 7 cases are being monitored, and research is ongoing. The severity of Omicron BF 7's behavior has yet to be determined.

Conclusion

India has reported different COVID variants, such as Alpha, Beta, Gamma, Delta, B.1.6, AY, Omicron, XE, XM, and XJ since the pandemic started. India is now experiencing a decline in COVID-19 cases. However, COVID-19 is continuously evolving into more evasive variants. The Omicron BF 7 variant may put all the gains achieved so far in vain because of its high transmissible rate. The impacts of BF 7 infection are being monitored. Following COVID-19-appropriate precautions and behavior is essential to prevent the spread of this mutated variant.
