Covid BF.7 Variant Explained!! New Variant Symptoms & Precautions

sssamiti.org

Covid BF.7 Variant Symptoms and Precautions: There is a havoc in China due to the Corona virus as hundreds of people are dying everyday. Hospitals are over crowded every day. Covid is wreaking havoc in China since the restrictions were relaxed in December. Omicron’s sub-variant bf.7 is now the reason for increasing cases in this country. The infectivity rate in this variant is quite high as the R value of the BF.7 variant is 18.

That is, a person infected with this variant can spread the virus to 18 people. This is the reason why Covid is spreading so fast in China. Here in this article we will update you about Covid BF.7 Variant, New Variant Symptoms & Precautions so read this carefully.

Since the beginning of November, cases of corona virus are increasing worldwide. The matter is under control in India now, but China is struggling very badly with it. According to some estimates, due to the recent increase, China is at risk of death of about two million people. An epidemiologist has even tweeted that 60% of China’s population could be infected in the next few months.

Corona outbreak in China is causing concern for many countries, but there is no serious threat in India. There were restrictions related to Covid in China till a few months ago. Due to poor medical policy, the situation in China is getting worse. Omicron’s bf.7 variant is also making a serious impact there. While this variant had arrived in India several months back but it had no effect here.

How does the new variant get the name BF.7?

BF.7 is actually short form. Full name is: BA.5.2.1.7. This is a sub-variant of Omicron’s BA.5 variant. Omicron’s BA.5 variant has the highest number of reported cases worldwide. About 76.2% of the total cases. However, the BA.4 and BA.5 sub-variants did not spread much in India. We have the highest number of BA.2.75 cases.

The corona virus is mutating and mutations can create many variants and sub-variants. This process is called convergent evolution. These sub-variants have been given names like BA.2.75.2, BF.7 and BQ.1.1. These names are determined by the fact that which sub-variant is derived from which variant.

How dangerous is the sub-variant Omicron?

The reports that are coming in China indicate that BF.7 is more dangerous than the rest of the Omicron sub-variants. It has the highest transmissibility as it spreads rapidly. A person infected with BF.7 can infect many people.

The remaining variants of Omicron can infect an average of 4 people and the incubation period of the variant is also less. The incubation period is the time between exposure to the virus and the appearance of the first symptoms. Meaning, as soon as you come in contact with BF.7, you can catch it immediately.

Has BF.7 arrived in India as well?

The BA.1 and BA.2 sub-variants of Omicron were found in the wave earlier this year. Later on BA.4 and BA.5 also came. However, both of them caused more devastation in European countries. Similarly, very few cases of BF.7 were observed in India. One case of this variant was reported in India in July, two in September and one in November and this variant has been found in Gujarat and Odisha in India.

New Variant BF.7- Symptoms

The symptoms of this variant are similar to those of the other subvariants of Omicron. An infected person may show symptoms of fever, cough, sore throat, runny nose, fatigue, vomiting and diarrhoea. This sub-variant can cause severe disease in people with weakened immune systems. If someone is having body pain for a long time, then he should get the Covid test done. Apart from this, sore throat, fatigue, phlegm and runny nose can also be symptoms.

Omicron BF.7: Precautions

Physical distance: Corona is caused by coming in contact with an infected person, so it is very important to maintain physical distance from people to avoid it. According to the CDC of America, to avoid infection, keep a distance of at least 6 feet from people in public places. By keeping distance, you can avoid getting droplets from someone who is coughing or sneezing.

Wear a Mask: Do wear a mask when you go out of the house. With this you will avoid drops of infection. Apart from corona virus, the mask also protects against other infections like flu, cold and cough. Throw away the mask after wearing it once. Also use a good quality mask.

Get a booster dose: If you haven’t got the booster dose of Covid yet, get it done immediately. There is no cure for Corona infection, so at this time only the vaccine can save us from its severe symptoms to a great extent.

Avoid going crowded places: To avoid corona infection, you also have to avoid going out and spend maximum time indoors.

Take care of cleanliness: You can also get infected by corona by touching an infected surface or person, so wash your hands to avoid infection. First apply soap on your hands and rub them for few seconds and then wash them with water.

Use a sanitizer: When you go outside use a sanitizer, if soap and water are not available then use a sanitizer.

Enhanced neutralization escape to therapeutic monoclonal antibodies by SARS-CoV-2 Omicron sub-lineages

Preliminary report; The landscape of SARS-CoV-2 variants dramatically diversified with the simultaneous appearance of multiple sub-variants originating from BA.2, BA.4 and BA.5 Omicron sub-lineages. They harbor a specific set of mutations in the spike that can make them more evasive to therapeutic monoclonal antibodies. In this study, we compared the neutralizing potential of monoclonal antibodies against the Omicron BA.2.75.2, BQ.1, BQ.1.1 and XBB variants, with a pre-Omicron Delta variant as a reference. Sotrovimab retains some activity against BA.2.75.2, BQ.1 and XBB as it did against BA.2/BA.5, but is less active against BQ.1.1. Within the Evusheld/AZD7442 cocktail, Cilgavimab lost all activity against all subvariants studied, resulting in loss of Evusheld activity. Finally, Bebtelovimab, while still active against BA.2.75, also lost all neutralizing activity against BQ.1, BQ.1.1 and XBB variants. https://www.biorxiv.org/content/10.1101/2022.12.22.521201v1?rss=1%22&utm_source=dlvr.it&utm_medium=tumblr Read more ↓

Halifax couples receive wrong COVID-19 booster

Nearly two weeks after their most recent COVID-19 shot, Heather Star Williams and Brian Williams are piecing together what went wrong.

“I’m disappointed that the system let me down,” said Heather Star Williams.

The two followed Public Health’s recommendation and booked appointments to receive a bivalent vaccine. In their case, they booked the Pfizer bivalent.

Their confirmation indicated they would receive that shot, but days after their appointment at their local Lawtons Drug Store, they said they received a call from the pharmacy.

“That we had been given not the bivalent that we had booked for, but rather, I think she said the original Pzifer,” Williams said.

The same thing happened to their friends Debbie and Percy Paris.

That couple went to a Sobeys pharmacy in a different part of the Halifax Regional Municipality on a different day.

“How could that have happened? What was their system that they could have not checked or double-checked,” Debbie Paris said.

She noted that during her appointment, she asked the person giving her the shot if she was getting the bivalent.

She says she was told yes.

“Something triggered me that day, you know, just make sure I’m getting the right one here,” she said. “Thought I was.”

Both couples said they’ve spoken with their pharmacies and said both were told the packaging is similar.

CTV News went to another pharmacy and compared the vials.

The labels on the vials were the same colour and nearly exact except the bivalent indicated it was a bivalent vaccine and had one extra line reading “Original and Omicron BA.4/BA.5.”

In a statement from the Pharmacy Association of Nova Scotia, spokesperson Martha Lowe indicated that the organization is unable to speak as to why an error has occurred in an individual pharmacy.

“However, vaccine vials are very similar in look and that this may be contributing to the errors. The Nova Scotia College of Pharmacists is looking at this issue to determine if there is a specific cause,” Lowe said.

Sarah Dawson, the Public Affairs Lead for Sobeys said they are following all Public Health guidance on the look-alike packaging.

“The information that we’ve shared with our affected pharmacy patients from the Public Health Advisory Committee is that if Pfizer-BioNTech or Moderna monovalent vaccines are used for a booster dose, they are considered valid,” Dawson said. “We are also taking our own additional steps to clearly differentiate the look-alike vaccine vials within our pharmacies to ensure that patients are getting the COVID-19 booster they requested when they booked.”

The couples question how often the mix up has happened. Both wanted to get the shot that was recommended by Public Health and are now concerned they didn’t.

“Knowing that I’m not protected for the variants is of some concern,” said Percy Paris, who called the mistake disheartening. “It’s not going to be consuming but it’s going to be somewhat alarming to me.”

Khalehla Perrault, a spokesperson for the Department of Health and Wellness, said as soon as the Department and Nova Scotia Health (NSH) became aware of the error, NSH released a memo to all vaccine providers reinforcing the difference between the two vaccines and how to avoid errors in administration.

Perrault said the Pfizer vaccine (ancestral) is authorized as a booster in Canada and is a safe and effective option for reducing the likelihood of severe outcomes from COVID-19, including the Omicron variant and Omicron sub-variants.

“Nonetheless public health is recommending that people 12+ years receive a bivalent vaccine for their fall dose,” she said. “If people have chosen to receive an ancestral Pfizer or Moderna vaccine as their fall dose, they do not need to book a bivalent dose.”

Perrault said individuals who have booked bivalent and who received ancestral vaccine by their provider will be offered an additional dose of a bivalent COVID-19 vaccine after a 3-month interval.

The Week In Review: #Philippines #PH #CoronavirusUpdates #COVID19 Globally, Europe now comprises more than 50% of the world’s daily cases. In East Asia, Taiwan continued to see rising cases as the Reproduction Rate (Rt) remained above 1. Japan sees a dramatic drop in cases, not because there are less COVID cases seen, but because in the way the reporting is done. The doctors are not mandated to fill up each and every report for all cases of COVID-19 any longer in the country. With the BA.5 and BA.4 and its sub variants dominating the globe in time for the winter season, some of the countries are notably seeing changing landscapes with many under testing, and simply living with the virus. The Philippines averaged 2014 daily cases with a Rt of 1.16 (+/- 0.05), meaning that we are at a plateau and should expect to see a tad higher cases this week. Singapore’s numbers are up at more than 5,250 daily cases and a Rt of 1.25.

Colleen Dempsey, 54, receives the Pfizer-BioNTech coronavirus illness (COVID-19) booster vaccine concentrating on BA.4 and BA.5 Omicron sub variants at Skippack Pharmacy in Schwenksville, Pennsylvania, U.S., September 8, 2022. REUTERS/Hannah Beier/File Picture (Reuters) -Round 3.9 million individuals in the US acquired up to date COVID-19 booster pictures over the previous week, the Facilities for Illness Management and Prevention mentioned on Thursday. The CDC mentioned a complete of 11.5 million People had acquired the shot as of Oct. 5, the primary 5 weeks the booster has been accessible. That is up from the 7.6 million individuals who acquired the shot as of Sept. 28. The 11.5-million determine represents solely 5.3% of the 215.5 million individuals in the US aged 12 or older who’re eligible to obtain the pictures as a result of they’ve accomplished their major vaccination collection. The pictures are being administered at a slower tempo than final yr, when the US initially approved COVID boosters only for older and immunocompromised individuals. Round 20 million individuals acquired their third shot within the first 5 weeks of that vaccination marketing campaign. A latest survey performed by the nonprofit Kaiser Household Basis discovered that just about two-thirds of adults in the US don’t plan to get up to date COVID-19 booster pictures quickly. The U.S. Meals and Drug Administration approved Pfizer (NYSE:) and Moderna (NASDAQ:)’s Omicron-tailored pictures in August in preparation for the nation’s ongoing fall revaccination marketing campaign. The CDC tally consists of booster pictures from each Pfizer/BioNtech and Moderna. Whereas the Pfizer/BioNTech up to date COVID-19 booster is accredited for these aged 12 and above, Moderna’s shot is accredited for people aged 18 and above. These Omicron-tailored pictures goal to sort out the BA.5 subvariants, which makes up a major majority of the at present circulating variants in the US, in accordance with authorities information. These pictures are anticipated to even be efficient towards the slowly rising BA.4.6 subvariant. Originally published at Irvine News HQ

Maturation of SARS-CoV-2 Spike-specific memory B cells drives resilience to viral escape

Preliminary report; Memory B cells (MBCs) generate rapid antibody responses upon secondary encounter with a pathogen. Here, we investigated the kinetics, avidity and cross-reactivity of serum antibodies and MBCs in 155 SARS-CoV-2 infected and vaccinated individuals over a 16-month timeframe. SARS-CoV-2-specific MBCs and serum antibodies reached steady-state titers with comparable kinetics in infected and vaccinated individuals. Whereas MBCs of infected individuals targeted both pre- and postfusion Spike (S), most vaccine-elicited MBCs were specific for prefusion S, consistent with the use of prefusion-stabilized S in mRNA vaccines. Furthermore, a large fraction of MBCs recognizing postfusion S cross-reacted with human betacoronaviruses. The avidity of MBC-derived and serum antibodies increased over time resulting in enhanced resilience to viral escape by SARS-CoV-2 variants, including Omicron BA.1 and BA.2 sub-lineages, albeit only partially for BA.4 and BA.5 sublineages. Overall, the maturation of high-affinity and broadly-reactive MBCs provides the basis for effective recall responses to future SARS-CoV-2 variants. https://www.biorxiv.org/content/10.1101/2022.09.30.509852v1?rss=1%22&utm_source=dlvr.it&utm_medium=tumblr Read more ↓
