BF.7, a wrinkle-improving subtype of Omicron?
This is not the first time that BF.7 has made headlines. The BF.7 began replacing the dominant version in the United States and several European countries last October.
The current increase in Covid-19 infections in China is thought to be attributed to the BF.7 Omicron subtype circulating in China. The BF.7 began replacing the dominant version in the United States and several European countries last October.
Covid Spike: what do we know about BF.7?
As the virus mutates, it creates lineages and lineages, such as the trunk, branch, and sub-branches of the Sars-CoV-2 tree. The BF.7 is similar to the BA.18.104.22.168 under the Omicron BA.5 range.
A study published earlier this month in the journal Cell Host and Microbe found that the BF.7 substrate was 4.4 times more resistant to the virus than the original D614G variant. BF.7 is the original Wuhan virus that spread worldwide in 2020.
But in BF 7 the most powerful is not roaded. In the same study, more than 10 times shock resistance was reported in another Omicron circuit, the BQ.1.
The higher the knockdown resistance, the more variants will spread through the population and drive out other variants.
In October, BF.7 was estimated to account for more than 5% of cases in the US and 7.26% of cases in the UK. Western scholars are exploring these aspects of art. However, a significant increase in cases of hospitalizations has been observed in these regions.
Is there a Covid-19 BF.7 strain circulating in India?
India’s January 2022 increases are driven by Omicron BA.1 and BA.2 sub-options. The later BA.4 and BA.5 subtypes were not as common in India as in European countries. Hence, there are a few examples of BF.7 (BA.5 branch) in India.
According to the National SARS-CoV-2 Genome Sequencing Network of India, BA.5 casts accounted for only 2.5% of cases in November. Recombinant XBB is now the most common type in India, accounting for 656% of all cases in November.
Covid Spike: what has changed in China?
Experts attribute the rise in cases in China to a growing unvaccinated population, not the high transmissibility of BF.7 exposure or immune evasion.
Dr. Anurag Agarwal, former head of India’s INSACOG Covid-19 Genome Sequencing Consortium, said: “China has now seen an increase in the Omicron index seen in other countries, just as Hong Kong has eased restrictions.
But isn’t the majority of the Chinese population vaccinated?
According to the World Health Organization, China has the highest vaccination coverage, with 235.5 vaccinations per 100 people. However, China was one of the first countries in the world to produce and introduce a vaccine due to its population, and the vaccine was first created against the type of coronavirus.
The virus has changed several times since the start of 2020, and Omicron variants are known to evade the immune response of most vaccines currently in use.
(Indeed, the Omicron wave in India infected many people who had been vaccinated twice.) That’s why many companies are developing bivalent vaccines for better protection.
Before Omicron, vaccines could control the spread of infection. Post-Omicron vaccines do not prevent transmission, they only prevent death. Agarwal.
A subvariant of Omicron BF.7 associated with the Chinese tip was first discovered in India in July.
BF.7 was confirmed in Gujarat and Orissa in four cases he had, but it was not linked to exacerbations or transmission, officials said after a meeting of health ministers on his COVID-19.
His BF.7 variant of COVID-19, believed to be responsible for the recent surge in cases in China, was first confirmed in India in July.
His four copies of the genome of the Omicron subspecies were subsequently sequenced in humans in Gujarat and Orissa over the next few months, which was associated with increased severity and infections in these two states. were not related, two senior officials who attended a meeting convened by the minister said. health. Mandavia independently confirmed the Hindus on Wednesday.
The health minister has held a meeting with senior officials from the National Covid Center and Task Force to assess the situation in India as the rising number of coronavirus cases in China has sparked global concern.
“COVID is not over. I have ordered all concerned to be more vigilant and to increase surveillance. I am also encouraging the general public to get vaccinated against COVID,” said Park. Mandavia said.
Omicron BF.7 was found in Odisha in samples tested on Sept. 30, 2022, the state Department of Health and Human Services said Wednesday Over the next three months in Orissa, he found no other specimens of BF.7,” he added.

Omicron BF.7 strain, the new strain of Covid-19 causing chaos in China, has also been detected in India, and four cases of Omicron BF.7 strain have been confirmed in India in the past six months. Highly infectious strains have been imported from Gujarat (2) and Orissa. Unlike China, many new coronaviruses have affected the country, but the Center has ordered all states and federal territories to be on alert. They reported that there are 10 types of Covid-19, the smallest of which is BF. 7.
On Thursday, Prime Minister Narendra Modi will hold a high-level meeting to discuss the Covid-19 situation and related aspects of the country.
This is a new type of coronavirus that spreads quickly to other people and has a short incubation period.
According to a report by Livemint’s sister publication, Hindustan Times, around 60% of the Chinese population will be infected with this strain in the next three months. Meanwhile, the virus is hard at work around the world, including in the United States, Hong Kong, South Korea, Japan, and Brazil. Eric Danzi, a Chinese epidemiologist, said the virus could kill millions of people across China over the next few months.
Federal Health Minister Mansour Mandavia chaired a high-level meeting yesterday to take stock of the covid-19 pandemic in the country. Mandavia urged people to take proper covid and covid-19 vaccine precautions. The latter, seeing that the epidemic was not yet over, appealed to the authorities and urged them to exercise sufficient vigilance to allow the guards to enter.
