COVID Omicron BF.7: Symptoms, Causes and Precaution

COVID Omicron BF.7: Symptoms, Causes, and Precaution will be discussed in this post. We are appealing to all our readers Covid New virus BF7 is spreading very fast in India and other countries.

Since the COVID-19 variation Omicron first appeared in late 2021, it has rapidly mutated into a number of subvariants. The World Health Organization (WHO) is “extremely concerned” about one subvariant, Omicron BF. (also known as Omicron BF.7), which is responsible for the current COVID infection epidemic in China and is reawakening concerns in other countries, including India.

Cases of BF.7 infection have been found outside of the UK, US, and European nations like Denmark, France, Germany, and Belgium as well.

There are concerns regarding the symptoms of this new variation, what it is, and whether it may start a new wave in India.

What is Omicron BF.7 Variant?

A branch of the Omicron variation BA.5 is the Omicron BF.7 strain. According to reports from China, among all the omicron sub-variants, sub-variant BF.7 is the most infectious and highly transmissible. Compared to other varieties, it takes less time to incubate and spread.

Additionally, the Omicron BF.7 has the ability to re-infect those who have already contracted COVID-19 and can even infect those who have received vaccinations.

What are the symptoms of the BF.7 variant?

The symptoms of BF.7 infection are largely upper respiratory infections, such as a runny nose, cough, fever, and sore throat. These symptoms are similar to those of other omicron sub-variants. In those with weakened immune systems, the infection might be more severe.

What could be the cause of faster spread?

According to studies, the R0 value of this mutant is approximately 10-18.6, meaning that those who are sick can spread the disease to 10-18.6 others nearby.

A specific mutation, “R346T,” has been found in the SARS-CoV-2 spike protein in the BF.7 variation (a protein on the surface of coronavirus that allows it to attach to and infect the cells).

It has been determined that this mutation, which is also present in variety BA.5 (the parent of BF.7), increases the virus’s ability to evade neutralising antibodies produced by prior infections or vaccinations. This indicates that the vaccination-induced antibodies are insufficient to protect against this virus.

Who is at higher risk of infection with the Omicron BF.7 variant?

Unvaccinated individuals are more at danger. The chance of contracting this infection is also increased in those with weakened immune systems, including as children, the elderly, pregnant women, and persons with numerous comorbidities, such as uncontrolled diabetes, cancer, kidney, or heart disease.

What Precaution Can Be Taken to Prevent Infection with BF.7?

It is more important than ever to behave in a COVID-appropriate manner, especially with Christmas and New Year’s celebrations just around the corner. The most basic measures to stop a potential spread are hand washing, mask use, and maintaining social distance.

Although seasonal illnesses like the cough, cold, and flu are widespread in India during these months, you should never disregard these symptoms. Get a COVID test done right away and practise self-isolation if you or someone nearby has a cough, cold, or other symptoms.


The BF.7 variation, like previous Omicron variants, has an extremely quick transmission rate. A person who has this virus, even if they are asymptomatic, can spread it to an additional 10 to 18 others. Even though the data show a low fatality rate for this variety and that there aren’t many hospitalisations or deaths in India, only time will tell what will happen in the coming days, weeks, or months. However, we need to exercise greater caution and adhere more strictly to COVID-appropriate behaviour (mask use, social withdrawal, and hand hygiene).
