The Food and Drug Administration is expected to soon authorize a pill made by Merck and Ridgeback Biotherapeutics, called molnupiravir, which reduces the risk of hospitalization and death from COVID-19 by 30% if taken within five days of the onset of symptoms.

 

Another antiviral pill, developed by Pfizer, may perform even better. An interim analysis showed that the drug was 85% effective when taken within five days of the start of symptoms. The FDA could authorize it by year’s end.

 

Since the start of the pandemic, scientists have hoped for convenient options like these: pills that could be prescribed by any doctor and picked up at a local drugstore. Omicorn medicine found : All Details

 

And these two pills may be just the beginning. With the threat of omicron and other variants looming, scientists say we will need an arsenal of drugs to deploy against new foes — especially if those variants erode the protection of existing vaccines.

 

 

A British scientist has made a big claim about the Omicron variant of Corona, which has terrified the world. In fact, he has said that his drug Sotrovimab has proved to be effective and effective against every mutation of Omicron.

This UK scientist told that he has developed this special drug by GlaxoSmithKline (GSK) in collaboration with US partner Vir (VIR) Biotechnology. Now this medicine is being considered effective against the Omicron variant.

 

 

Relief news for the world

GSK, the company developing this Kovid-19 antibody-based therapy, said that the preclinical data of sotrovimab has been found to be very effective against many other variants of corona, including Omicron, which has caused worldwide concern.

In October, Merck announced the initial results of its molnupiravir trial: The drug reduced the risk of hospitalization and death by about 50%. Eager to curb the toll of COVID-19, the U.S. government has bought approximately 3.1 million courses of molnupiravir for about $2.2 billion.

 

But in the final analysis of the trial, the drug’s effectiveness dropped to 30%. Omicorn medicine found : All Details

 

At a Nov. 30 meeting of an FDA advisory committee, experts discussed the potential for the drug to cause mutations not just in viruses, but in people’s own DNA. The committee voted to recommend authorizing molnupiravir, but only by a slim majority. And even the committee members who voted in favor of the drug expressed reservations, given the potential side effects.

 

Pfizer’s drug is next to enter the spotlight. Its origins reach back nearly two decades, to when Pfizer researchers were searching for a drug that could fight the coronavirus that caused SARS. They decided to build a molecule that could block an essential viral protein, known as a protease. Proteases act like molecular scissors, cutting long molecules into pieces that help build new viruses.

The drug, originally called PF-00835231, lodged in the protease like a piece of gum crammed between scissor blades. PF-00835231 proved effective against SARS when given intravenously to rats.

 

The SARS epidemic ended before the Pfizer could launch a clinical trial. But after the COVID-19 pandemic hit last year, researchers at the company pulled the drug off the shelf to try against SARS-CoV-2.

 

They modified it to work against the protease of the new coronavirus and tinkered with the molecule so it would work as a pill. Paxlovid, as Pfizer has branded the drug, came out of clinical trials last month with terrific initial results: 85% effectiveness if taken within five days of the onset of symptoms. It remains to be seen if the number stays that high in the final analysis.

 

Shortly after announcing the interim results, Pfizer applied for FDA authorization of Paxlovid and reached a deal with the U.S. government to provide up to 10 million courses of the drug for $5.3 billion.

As the FDA reviews the company’s application, it will consider not just the effectiveness of Paxlovid, but also its potential side effects. Unlike molnupiravir, Paxlovid does not introduce mutations, so it probably won’t raise the same red flags.

 

“Given that it works through a different mechanism unrelated to our genetic material, it is less likely to cause changes in our DNA,” said Sara Cherry, a virus expert at the Perelman School of Medicine at the University of Pennsylvania. But, she added, “protease inhibitors have different liabilities.”

 

Our own cells make proteases, which we use to whittle down our own proteins, enabling them to perform new jobs. Although many protease-inhibitor drugs have proved safe, some of them can also lock onto our proteases instead of the proteases made by viruses. Still, the short course of pills needed to stop COVID-19 may reduce any such risk from a drug such as Paxlovid.

 

Are COVID-19 vaccines effective against Omicron?

Vaccines remain the best public health measure to protect people from COVID-19 while slowly transmission and reducing the likelihood of new variants emerging. The CDC and WHO continue to work to better understand the potential impact of the Omicron variant on existing countermeasures. This analysis of Omicron variant vaccine efficacy includes the COVID-19 vaccines and boosters from Moderna, Pfizer-BioNTech and Johnson & Johnson.

 

"Emergence of the Omicron variant further emphasizes the importance of vaccination, boosters and prevention efforts needed to protect against COVID-19,” said CDC Director Rochelle Walensky, MD, MPH. “Early data from South Africa suggest increased transmissibility of the Omicron variant, and scientists in the United States and around the world are urgently examining vaccine effectiveness related to this variant.”

 

The CDC recommends that everyone 5 or older get fully vaccinated to protect against COVID-19. Everyone 18 or older should also get a booster shot. Omicorn medicine found : All Details

 

Should I get the COVID-19 vaccine or booster shot?

It is imperative that everyone who is not fully vaccinated against COVID-19 get vaccinated. And those who are fully vaccinated and eligible should get a booster shot for added protection against COVID-19 variants.

 

“I strongly encourage the 47 million adults who are not yet vaccinated to get vaccinated as soon as possible and to vaccinate the children and teens in their families as well because strong immunity will likely prevent serious illness,” Dr. Walensky said. “I also want to encourage people to get a COVID-19 test if they are sick. Increased testing will help us identify Omicron quickly.”

What mask should I wear to prevent Omicron?

Given how contagious Omicron is, some experts recommend upgrading from a cloth mask to an N95 or similar high-filtration respirator when in public indoor spaces. These masks are made of material with an electrostatic charge, which can help prevent you from inhaling virus particles.

 

At minimum, though, consider double masking. This means wearing a cloth mask over a surgical mask for a tighter fit. A mask fitter can also help improve the fit of a person’s mask for better protection against Omicron. While double masking or a mask fitter may not offer as much protection as an N95, they are a big improvement compared to a cloth mask alone.

 

The AMA strongly supports vaccination of all who are eligible to protect against the worst outcomes of COVID-19. Among other things, the AMA supports COVID-19 vaccine mandates by employers and appropriate take-up of COVID-19 vaccine booster shots.

What is the Omicron variant of COVID-19?

First reported to the World Health Organization (WHO) by South Africa, B.1.1.529 was classified as a variant of concern and named Omicron on Nov. 24. This prompted the U.S. and several other countries to restrict travel to and from South Africa. The U.S. was set to lift those travel restrictions Dec. 31.

 

The first U.S. case of the Omicron variant was identified in an individual in California. This individual, who was fully vaccinated, traveled from South Africa on November 22 and tested positive for COVID-19 on November 29. The person is reported to have mild illness. The Centers for Disease Control and Prevention (CDC) and the WHO have classified Omicron as a “variant of concern.”

 

State and local public health officials continue to work with the CDC to monitor the spread of Omicron. As of December 20, the Omicron variant “has been detected in most states and territories and is rapidly increasing the proportion of COVID-19 cases it is causing,” said the CDC.

 

What makes Omicron a variant of concern?

In recent weeks, COVID-19 infections in South Africa saw a steep increase, coinciding with the detection of the Omicron variant. At this article’s deadline, Omicron accounted for nearly 60% of cases in the United States, according to data from the CDC. Omicorn medicine found : All Details

 

What makes this variant concerning is the number of mutations, which may have an impact on how easily Omicron spreads or the severity of illness it causes, says the WHO. There is also a potential reduction in both the efficacy of the monoclonal antibody treatments and in the neutralization by post-vaccination sera, says the CDC.

How contagious is the Omicron variant of COVID-19?

The Omicron variant is still new, but the WHO has noted that this COVID-19 variant is more easily spread from person to person. It is possible that with Omicron’s more than 30 mutations, it is helping the variant spread more easily while allowing it to evade protective immunity generated by vaccines or natural immunity through previous infection.

 

In fact, on Dec. 14, the WHO noted that the Omicron variant is spreading faster than any previously detected strain of SARS-CoV-2. But while the COVID-19 Omicron variant is more contagious, it is not yet entirely clear whether the strain causes more milder or more severe disease than others.

 

Does Omicron cause more severe disease?

Again, it is not yet totally evident whether infection from the COVID-19 Omicron variant causes more severe disease. But preliminary data does suggest that the rates of hospitalization in South Africa have been increasing.

 

Preliminary studies of the Omicron variant suggest that infections may be less severe than those experienced from Delta. But, with Omicron, the virus spreads more quickly, which remains a cause for concern. More data is needed to better understand whether Omicron infections—especially reinfections and breakthrough infections in people who are fully vaccinated—cause more severe illness or death than infection with other variants, says the CDC.

 

What are the symptoms of the Omicron variant?

Early evidence suggests that for those who are fully vaccinated against COVID-19, Omicron appears to result in mild illness. This can resemble the common cold, which is another form of the coronavirus. These symptoms can include sore throat, headache, cough, fatigue, congestion and runny nose.

 

The initial reports of infections, according to the WHO, were among college students who tend to have milder symptoms. Understanding the true level of severity of the Omicron variant could take several weeks.

 

Is there an increased risk of reinfection?

While research is ongoing, preliminary evidence suggests that there might be an increased risk of reinfection with the COVID-19 Omicron variant. This means that people who have previously tested positive for COVID-19 and recovered can become reinfected more easily with Omicron, according to the WHO. More information will become available in the upcoming weeks. Omicorn medicine found : All Details

Could Omicron variant of COVID-19 be less serious than Delta?

People who get COVID-19 infections caused by the Omicron variant are less likely to need hospital care, compared with those infected by the Delta variant, according to two large new studies from the U.K. and South Africa.

 

 

Covid-19 experts on which treatments hold up against omicron and which ones to ask a doctor about if you get sick.

 

There’s still a lot we don’t know about the coming omicron wave, but there’s one thing we can be pretty sure about: A lot of people are going to get sick. Omicron is highly contagious, and people with previous immunity from a Covid-19 infection, or from vaccination, appear more vulnerable to omicron than to previous variants.

 

For vaccinated people, omicron cases are likely to be mild, but even a small fraction of cases resulting in hospitalization can overwhelm hospitals if enough people get sick at once — which looks likely to happen.

 

That means that as the wave sweeps the country, people will have an obvious if critical question: What treatments are available to me if I get sick with Covid-19?

 

The good news is that scientists have more answers to that question than they did two years ago when Covid-19 first hit. Most of the treatments that researchers have tested in large clinical trials haven’t panned out, but a few look promising, including some that are cheap and safe. If you get sick, it’s worth fully exploring your options. We asked experts how the best existing treatments are expected to stand up to omicron in particular, and what to look into if you get sick.

 

Promising treatments to talk to your doctor about

The official Centers for Disease Control and Prevention guidance on what to do if you get sick with Covid-19 advises you to wear a mask, wash your hands, and clean high-touch surfaces to avoid infecting those around you. If your breathing deteriorates or you show signs of severe illness like confusion or an inability to stay awake, the CDC advises you to go to the hospital.

 

All sound guidance — but advice on what treatments to get is harder to come back

That’s not because there’s a lack of options. On Wednesday, the Food and Drug Administration approved Pfizer’s Paxlovid, a protease inhibitor — which means it blocks an enzyme needed for viral replication. The drug showed an impressive 88 percent efficacy in preventing hospitalization among unvaccinated patients — it was so effective that in November, the clinical trial stopped enrolling new participants because investigators concluded it would be unethical to put them in the control group.

 

What is Omicron?

Omicron is a new variant of the virus that causes COVID-19. The World Health Organization declared it a 'variant of concern' on 26 November 2021.

 

 

What is the meaning of the name Omicron for the COVID-19 variant?

“Mikron,” a form of “mikros,” means “little,” so it is literally a “little o.” It contrasts with the final letter of the Greek alphabet, “omega,” which comes from “o mega” or “large o.” The two letters got their names because “omicron” represents a short vowel in Greek and “omega” a long vowel.

 

Is COVID-19 variant Omicron worse than Delta variant?

Anthony Fauci claimed that while it would take weeks to judge the severity of the new Covid-19 variant Omicron, early indications suggested it was not worse than prior strains, and possibly milder.

 

 

How do viruses get their name?

Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV)

 

What are some symptoms of the COVID-19 Omicron variant?

 

Most common symptoms for the new COVID Variant “Omicron” are fever, cough, tiredness, loss of taste or smell.

 

What are symptoms of Omicron variant of COVID-19?

The World Health Organization's top official in Europe Hans Kluge said 89 percent of those with confirmed Omicron infections in Europe reported symptoms common with other coronavirus variants, including cough, sore throat, fever.

 

 

Omicron symptoms: How they differ from Delta, the flu, and a cold, and how quickly they’ll show up

 

 

 COVID-19 symptoms—a cough, fever, or loss of smell or taste—are still indicators of a possible infection, researchers have found that Omicron symptoms can also be similar to that of a common cold.

 

The Delta variant’s symptoms have also been compared to the common cold, but some doctors have shared that Omicron cases they’ve seen so far have been particularly mild.

 

A U.K. study of around 750,000 people found recently that the top five symptoms for both the Delta and Omicron variants are currently a runny nose, headache, fatigue, sneezing, and a sore throat. According to the South African doctor who first detected the Omicron variant, initial patients also experienced body aches and a scratchy throat.

Omicron appears to be more contagious with symptoms that show up faster, but questions about severity remain

While it’s taken four or five days for coughs, headaches, and fevers to manifest when infected with previous COVID strains, the incubation timetable for Omicron may be even more abbreviated.

 

Data is still limited on COVID’s latest variant, which was first detected in Botswana and South Africa in mid-November, but a recent study in Norway indicates a median three-day window between exposure to the Omicron variant and symptoms—meaning that Omicron is able to spread more quickly, Fortune’s Jessica Mathews reports.

 

Preliminary studies of the Omicron variant have suggested that infections may be less severe than those experienced from the Delta variant.

 

However, it spreads more quickly. Last week, the World Health Organization said that Omicron is spreading faster than any other previous strain and that the variant is probably already in most countries, even if it has not been detected yet.

 

A analysis published by South African researchers last week found that the risk of hospitalizations among adults who had COVID-19 was 29% lower for people who had the Omicron variant compared to the first wave of infections in 2020. However, the continent of Africa also experienced an 89% surge in new COVID-19 cases over the past week, the fastest surge since May 2020.

 

A different study from the Imperial College London found that in the Omicron cases they analyzed, infection was not any less severe than those from the Delta variant.  Omicorn medicine found : All Details

 

The Johnson & Johnson, Sputnik, and Sinopharm vaccines have also been found to be largely ineffective when it comes to protecting against Omicron, studies have shown. And because of the variant’s high number of mutations, health experts are saying that it may be significantly resistant to the Pfizer and Moderna vaccines as well.

 

U.S. cities should expect a winter surge in cases

Experts say that even without Omicron, COVID infections are going through a “winter surge.” Currently, there is an average of 83,000 new COVID cases in the U.S. every day, even with 61% of the population vaccinated.

 

On Friday, the seven-day national average of new daily cases surpassed 197,000, representing a 65% increase over the past 14 days, the New York Times reported. Deaths also increased by 3% during that time. The highest national average for daily cases was set in January 2021, at 251,232, in the days following the holidays.

People are reacting quickly to Omicron’s spread

Just before the holidays, Cornell University shut down its campus after discovering 900 positive COVID cases, according to Bloomberg. Stanford University also announced its decision to return to online classes for the first two weeks of its winter quarter due to concerns around the Omicron variant, while Princeton University has moved all of its final exams online.

What are the primary symptoms of COVID-19?

Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually result in phlegm) and in a few cases loss in smell and taste. A few cases have also reported diarrhoea and fatigue.

 

Can you have the coronavirus disease without a fever?

Can you have coronavirus without a fever? Yes, you can be infected with the coronavirus and have a cough or other symptoms with no fever, or a very low-grade one, especially in the first few days. Keep in mind that it is also possible to have COVID-19 with minimal or even no symptoms at all

 

Update on Omicron

Current knowledge about Omicron

 

Researchers in South Africa and around the world are conducting studies to better understand many aspects of Omicron and will continue to share the findings of these studies as they become available. 

 

Transmissibility: It is not yet clear whether Omicron is more transmissible (e.g., more easily spread from person to person) compared to other variants, including Delta. The number of people testing positive has risen in areas of South Africa affected by this variant, but epidemiologic studies are underway to understand if it is because of Omicron or other factors. 

 

Severity of disease: It is not yet clear whether infection with Omicron causes more severe disease compared to infections with other variants, including Delta.  Preliminary data suggests that there are increasing rates of hospitalization in South Africa, but this may be due to increasing overall numbers of people becoming infected, rather than a result of specific infection with Omicron.  There is currently no information to suggest that symptoms associated with Omicron are different from those from other variants.  Initial reported infections were among university students—younger individuals who tend to have more mild disease—but understanding the level of severity of the Omicron variant will take days to several weeks.  All variants of COVID-19, including the Delta variant that is dominant worldwide, can cause severe disease or death, in particular for the most vulnerable people, and thus prevention is always key.

 

 

 

Effectiveness of prior SARS-CoV-2 infection

 

Preliminary evidence suggests there may be an increased risk of reinfection with Omicron (ie, people who have previously had COVID-19 could become reinfected more easily with Omicron), as compared to other variants of concern, but information is limited. More information on this will become available in the coming days and weeks.

 

Effectiveness of vaccines: WHO is working with technical partners to understand the potential impact of this variant on our existing countermeasures, including vaccines. Vaccines remain critical to reducing severe disease and death, including against the dominant circulating variant, Delta. Current vaccines remain effective against severe disease and death.  

 

Effectiveness of current tests: The widely used PCR tests continue to detect infection, including infection with Omicron, as we have seen with other variants as well. Studies are ongoing to determine whether there is any impact on other types of tests, including rapid antigen detection tests. 

How fast is Omicron spreading?

Omicron’s rapid rise in South Africa is what worries researchers most, because it suggests the variant could spark explosive increases in COVID-19 cases elsewhere. On 1 December, South Africa recorded 8,561 cases, up from the 3,402 reported on 26 November and several hundred per day in mid-November, with much of the growth occurring in Gauteng Province, home to Johannesburg.

 

 

Can Omicron overcome immunity from vaccines or infection?

The variant’s swift rise in South Africa hints that it has some capacity to evade immunity. Around one-quarter of South Africans are fully vaccinated, and it’s likely that a large fraction of the population was infected with SARS-CoV-2 in earlier waves, says Wenseleers, based on heightened death rates since the start of the pandemic.

 

 

How will vaccines fare against Omicron?

If Omicron can dodge neutralizing antibodies, it does not mean that immune responses triggered by vaccination and prior infection will offer no protection against the variant. Immunity studies suggest that modest levels of neutralizing antibodies may protect people from severe forms of COVID-19, says Miles Davenport, an immunologist at the University of New South Wales in Sydney, Australia.

 

Will current boosters improve protection against Omicron?

The threat of Omicron has prompted some rich countries, such as the United Kingdom, to accelerate and broaden the roll-out of COVID vaccine booster doses. But it’s not yet clear how effective these doses will be against this variant.
