There could be an increase in the number of Covid-19 cases in the winters, when we usually see an increase in all respiratory infections.” “The mutations in the spike protein have slowed down, there hasn’t been a massive change in around a year. “There is a debate about whether certain vaccines are better than the others. The January 2022 wave in India was driven by the BA.1 and BA.2 sub-variants of Omicron. Plus, we have already paid the price, so to say, during the Delta wave (of April-May 2021). After Omicron, the vaccines aren’t really able to stop transmission, but they do prevent deaths,” Dr Agarwal said. China indeed has a high vaccination rate — 235.5 doses per 100 population as per the WHO dashboard. BF.7 accounted for more than 5% of US cases and 7.26% of UK cases in October. This isn’t the first time that BF.7 has made news — in October, it started to replace the variants that were then dominant in the United States and several European countries. Other than that, Omicron has mainly been killing its elderly victims and we (India) do have a younger population,” Dr Agarwal said. As per data from India’s national SARS-CoV-2 genome sequencing network, BA.5 lineages accounted for only 2.5% of cases in November. When viruses mutate, they create lineages and sub-lineages — like the main trunk of the SARS-CoV-2 tree sprouting branches and sub-branches.

Three cases of BF.7 strain, that is driving the current wave of Covid infections in China, have been detected in India so far. Will it cause a fresh wave in ...

And India paid its price with the delta wave where we lost a lot of our people and those who survived have good immunity to covid and so is the status of our very good vaccination. Test-Track-Treat-Vaccinate is the most important strategy to check this infection and its community outbreaks," says Dr Arora. "Till now it is not clear which age group it affects the most but it is certain that people with low immunity are at a higher risk. It is also probable that if people get three to four shots of the vaccine, they may get protected. It is a variant mutant of the Omicron and has one of the highest transmissibility amongst all COVID variants so far. With restrictions eased out worldwide and the festive season in-swing, it is important to continue mass vaccination drive. “The signs and symptoms of BF.7 are pretty similar to other omnicorn variants fever, sore throught, runny nose. [Omicron BF.7 strain](https://www.hindustantimes.com/world-news/covid19-scare-grips-china-what-we-know-about-new-bf-7-omicron-variant-101671607167480.html), that is driving the current wave of [Covid infections](https://www.hindustantimes.com/lifestyle/health/new-omicron-sub-variants-5-ways-mild-covid-infections-are-affecting-our-health-101667389538387.html) in China, have been detected in India so far. In India, there are very few cases of mortality and hospitalization but it also depends on various factors including a person’s immunity and pre-existing comorbidities," says Dr Ghosh. Three cases of BF.7 strain, that is driving the current wave of Covid infections in China, have been detected in India so far. He says that a fourth shot of vaccine may be helpful in preventing these probable deaths. "The wave of Covid-19 in China is being caused by virus Omicron BF.5.2.1.7, also called as BF.7.

China Covid wave: Union Health Minister Mansukh Mandaviya earlier today held a meeting and gave directions for genome sequencing of new Covid cases.

Post genome sequencing directions by the Centre, at least 4 new Covid cases in India have been found to be of Omicron sub-variant BF.7. 10 points](https://www.indiatvnews.com/news/world/china-covid-explosion-epidemiologist-warning-for-world-three-new-covid-waves-60-percent-chinese-will-be-infected-2022-12-20-832781) India at the same time is fully alert to battle the new variant with Union Health Minister Mansukh Mandaviya giving directions for genome sequencing of new Covid cases. Experts have predicted that almost 60 per cent of China, 10 per cent of world would be affected by new Covid wave. - Omicron sub-variant BF.7 also known as BA.5.2.1.7 is a sub-lineage of the BA.5 variant. China Covid Wave: Attention has once again been brought back to Covid-19 after a turbulent surge of new infections driven by Omicron sub-variant BF.7 in China, ever since the country eased zero-Covid-policy.

At least four cases of the Omicron sub-variant BF.7, the Covid strain driving China's current surge of cases, have been detected in India so far.

Of these, BA.2 and BA.5 proved to be stronger than the rest. One death was recorded over the last 24 hours. It has already been detected in several other countries, including the US and UK and European nations such as Belgium, Germany, France and Denmark. BA.5.1.7 and BF.7 are names given to downstream descendants of BA.5." I have directed all concerned to be alert and strengthen surveillance. After a review meeting on Wednesday, Health Minister Mansukh Mandaviya tweeted, "COVID is not over yet.

BF.7 was identified in four cases in Gujarat and Odisha, but not linked to increased severity or infectiousness, say officials after Health Minister's ...

[XBB, a recombinant variant](https://www.thehindu.com/sci-tech/health/covid-19-mild-disease-no-severity-among-indian-patients-insacog-on-omicrons-xbb-variant/article66085987.ece) that was a combination of two lineages (BJ.1 and BA.2.75) but was “highly infectious,” responsible for a surge in many countries and which had the potential to evade antibodies from existing vaccines. “A new and highly transmissible BF.7 strain of the Omicron variant has been found to be behind a wider surge of covid infections in China,” it added. However, modelling studies estimate a spike in cases in China in early January and two other spikes in mid-January and February because of a rise in travel. That BF.7 is responsible for China’s current spike is just a conjecture based on very limited samples, though it’s almost quite certain it’s some Omicron-linked variant,” said [Vinod Scaria](https://www.thehindu.com/profile/author/Vinod-Scaria-14313/), of the CSIR-Institute of Genomics and Integrative Biology. They believe this has resulted in a large number of people who were unexposed to variants such as Alpha and Delta now being infected by the Omicron subvariant. In India, so far about 2.2 crore vaccines have been administered, though only around 28% of those above 18 years have had three doses. The dominant variant in India currently is Omicron AB5, (which is linked to BF.7) athough this is based on extremely limited numbers. Some studies expected a million COVID-19 deaths in China in the coming days. Officially, only 5,200 peope have died from COVID-19 in China over the last three years. Globally however, there has been a rise in daily average cases in the last six weeks, with about 6 lakh instances reported weekly as of December 19, the Health Ministry said in a statement. Omicron BF.7 was detected in Odisha in a single sample tested on September 30, 2022, the State’s Health and Family Welfare department said on Wednesday. In the 3 months since, no other sample of BF.7 has been detected in Odisha,” it added.

[new subvariant BF.7](https://www.businesstoday.in/coronavirus/story/covid-variant-bf7-spreading-like-wildfire-in-china-how-worried-should-you-be-357236-2022-12-21), is a sub-lineage of the BA.5 Omicron variant, which is reportedly the most infectious variant known so far since the discovery of SARS-CoV-2 in 2020. It has urged Beijing to speed up its vaccination drive of the most vulnerable. [#BF7]variant is true (2-3x more than old [#Omicron]), and resistant to neutralization even if vaccinated with older vaccines & [#COVID]infections of BA1/5, then China will be in a world of hurt—Hospitals near full. So, officially, there were only five Covid deaths on Tuesday, two on Monday - and none in the previous two weeks. Asymptomatic cases and positive results from home-testing kits are not recorded in the data. "Omicron BF.7 has more immune escape capability, a shorter incubation period, and faster transmission rate than other variants found so far," said Li Tongzeng, who works at Xiaotangshan Hospital in Beijing told the state-run newspaper, The Global Times. Patients may have fever, cough, sore throat, and other symptoms, with some symptoms like vomiting, diarrhoea, and others. Visited crowded crematorium in Beijing, people told me their loved ones died of covid— Selina Wang (@selinawangtv) Its reproduction number, or RO, is 10 to 18.6, whereas Delta’s RO was 5 or 6. Experts and projections have predicted that the situation could get severe in the coming winter months. As per news reports, BF.7 started spreading from October, and cases were reported in the United States and several European countries. China's only reported a few covid deaths since reopening.
