What is bf.7 Variant? – Everything You Need To Know

What is bf.7 Variant ? :  The new corona virus variant, bf.7 variant is a subvariant of the BA.5 this is a highly transmissible subvariant of Omicron. Concerns about a recurrence of the pandemic’s early stages are spreading worldwide as China faces a new coronavirus outbreak. In this article we will try to give some information and knowledge related to bf.7 variant.  The COVID-19 virus has been present all over the world since its emergence at the end of 2019 and has had time to evolve and mutate, resulting in waves upon waves of infections and almost constant emergence of new variants.

Like all other Omicron variants, the BF.7 variant transmits very quickly. Even if an infected person does not show any symptoms, they can spread the virus to 10 to 18 other people. While the pace of casualty, according to the information, isn’t high for this variation and in India there are not many instances of mortality and hospitalization, just time will uncover what occurs in the following couple of weeks or months. However, we should exercise greater caution and strictly adhere to COVID-appropriate behavior (wearing masks, avoiding social contact, and hand hygiene).

The virus BF.7 variant is a subvariant of the BA.5 which is a highly transmissible subvariant of Omicron. BF.7 is the abbreviation for BA. The coronavirus variant BF.7 according to reports, it is more infectious than the other variants. When viruses mutate, they form Lineages and sub-lineages, like SARS-CoV-2, which is like a tree with branches and subbranches that are its subvariants. The Omicron variant BF.7 is the most infectious, has a shorter incubation period, and is highly transmissible. SARS-CoV-2’s spike protein underwent a particular modification known as R346T, which led to the creation of BF.7 variant.  BF.7’s have also been found to have this mutation. Hence, we can say BF.7 variant is a highly transmissible subvariant of the Omicron’s BA.5

 All you need to know about BF.7 Variant

This isn’t the first time BF.7 has been talked about. In October, it started to replace the variants that were the most popular in the United States and a few European nations.

This BF.7 variant of Omicron is one of the Covid variants with the highest transmissibility. On November 22, only 2.5% of cases were from BA.5 lineages, despite the fact that the BF.7 variant was discovered in India as early as October.

The BF.7 sub-variant has a neutralization resistance that is 4.4 times higher than that of the original D614G variant, according to a study that was published in the journal “Cell Host and Microbe.” This means that in a laboratory setting, antibodies from a vaccinated or infected individual were less likely to destroy BF.7 than the original Wuhan virus, which spread worldwide in 2020, according to The Indian Express.

This indicates that the body’s immunity to the virus, whether acquired through previous infection or vaccination, is quickly bypassed by this variant. While a variant with a higher neutralization resistance indicates a greater likelihood of the variant replacing other variants in population.

How well-known is BF.7?

The Omicron variant BF.7, which is a sub-lineage of the BA.5 variant, is the most susceptible to infection, has a shorter incubation period, and is more likely to reinfect people who have been vaccinated. The Gujarat Biotechnology Research Centre discovered the first BF.7 case in India in October. Two cases have been reported so far, one from Odisha and two from Gujarat. (* by the time this article is published the original data may be changed). Chinese medical experts have said that the variant can be highly infectious and spread quickly. “Li Tongzeng, who works at Xiaotangshan Hospital in Beijing, told state-run newspaper The Global Times that Omicron BF.7 has more immune escape capability, a shorter incubation period, and a faster transmission rate than other variants found so far,” Li Tongzeng said.

          Five Facts About the Omicron BF.7 Variant

Facts About the Omicron BF.7 Variant

  1. The new sub-variant’s symptoms are similar to those of the common cold and include body pain, fever, coughing, and so on. It quickly spreads to a larger population due to its high transmission rate.
  2. The Bf.7 virus flood in China is credited to a low degree of resistance, which could be because of past diseases.
  3.  It has been reported that the subvariant has a high capacity for reinfection, even unvaccinated individuals.
  4.  Due to its high transmissibility, the BF.7 variant possesses the highest infection capacity.
  5.  The highly transmissible BA.5 subvariant of Omicron contains a subvariant known as the BF.7 variant.
  6.  According to experts, the BA.2 and BA.5 subvariants of Omicron are thought to be highly transmissible and to have sub lineages that continue to emerge.

Differences Between Influenza (Flu) and Corona virus variants and its Sub Variant

Both respiratory illnesses are contagious, but their viruses are distinct. SARS-CoV-2, a coronavirus, is the cause of COVID-19 variants, and influenza viruses are the cause of the flu. Because some of the symptoms are the same, you can’t tell the difference between the flu and Corona virus variants and its sub variant, just by looking at their symptoms. Some PCR tests can distinguish between the flu and Corona virus variants simultaneously. Numerous testing facilities offer separate COVID-19 and flu tests if one of these is unavailable. If you are experiencing symptoms, talk to your doctor about getting tested for both the flu and Corona virus variants and its sub variants.

When to Seek Medical Attention Right Away

Look for the following corona virus / bf.7 emergency warning signs: Pale, gray, or blue skin, lips, or nail beds, depending on skin tone If someone is exhibiting any of these symptoms, call an emergency number, visit the nearest hospital, or call to your local emergency facility to take the necessary action at the earliest.

What symptoms does variant BF. 7 present?

Patients should get tested for Covid-19 and its subvariants as soon as they experience symptoms in order to receive appropriate treatment and avoid cluster transmission. To combat the Omicron variant of Covid-19 and its sub variants, individuals ought to adhere to the directive as stated and the recommendation made by your doctor. This could mean wearing face masks, washing your hands frequently, and keeping a 1.5-meter distance from other people.

The following symptoms are indicative of Omicron variants: If you or any one near you is suffering from a new, persistent cough that lasts more than an hour or has three or more episodes in a 24-hour period, a change or loss in your sense of taste or smell, difficulty breathing, being worn out or exhausted need to undergo covid 19 and its subvariant testing at the earliest.

What is the incubation period for the new omicron Variant?

The incubation period is the time that passes between being exposed to the virus and experiencing disease symptoms like a cough, fever, shortness of breath, loss of taste or smell, or both. According to the Centres for Disease Control and Prevention, the omicron variant reduces the amount of time it takes for an infected person to experience symptoms following an exposure from a full week to as little as three days or less.  COVID-19 typically requires an incubation period of 5 to 6 days, but it can take up to 14 days.
