What we know - and do not know - about the omicron variation

Early research is beginning to paint a picture of omicron symbols, the effectiveness of the vaccine and the spread of diversity around the world.

As the incidence of different coronavirus infections is increasing worldwide, scientists are rushing to produce more variable variations in order to understand how they spread and to estimate new risks within the epidemic.

The first study released this month provided some clues as to the effectiveness of vaccines against microbial variability and whether it causes serious illness, but much remains to be seen, and further research is needed.

Here is what is known so far about the omicron variation.

Why does the omicron worry?

Varieties such as the omicron are a major threat to any end of the epidemic - and scientists warn that they will continue to emerge as the virus spreads.

The omicron variant involves more than 30 mutations in viral spike proteins, covering the outside of the virus and which are the main targets of vaccines and treatments similar to monoclonal antibodies.

Genetic modification may help the alternative to spread more easily and may allow you to escape the immune system produced by vaccines or by natural infections. The World Health Organization said in an analysis Tuesday that omicron mutations are spreading faster than any other type of coronavirus ever detected.

Does the omicron variant cause illness or more severe symptoms?

Evidence so far does not suggest that it is, but it may be too early to say.

The first major real estate analysis of this type, released this month, looks at the South African cases, which were first discovered last month. The results suggest that it may cause a much lower incidence than delta diarrhea, which is still the leading form of coronavirus in many countries. South African health officials have found that on average, fewer than 29 percent of hospitalized people are hospitalized than during the previous delta wave.

Although the data is encouraging, experts say it is too early to know whether the omicron variant causes minor illnesses or other factors, including young South Africans, are contributing.

In the US, too, the first few confirmed omicron cases were very mild, reports the Centers for Disease Control and Prevention.

The CDC screened 43 infected people, one of whom was hospitalized for two days, and found that the most common symptoms were coughing, fatigue, and runny nose. More than three-quarters of the participants were fully vaccinated, and one-third of those people also had positive images, according to the CDC.

CDC Director, Dr. Rochelle Walensky, who called the report "a priority," added that the agency would continue to monitor the variance carefully. Experts also warn that even if the omicron variant causes minor illnesses, a major increase in disease could override health care systems in severely affected countries.

Is it contagious?

Most previous studies suggest that the omicron variant is more contagious than previous strains of coronavirus, but a clear picture of its transmission is still unknown.

The number of cases in the worst-hit areas, such as South Africa and the United Kingdom, is growing rapidly, indicating that the differences are highly contagious, but research is still ongoing. The Omicron was first recognized in South Africa last month, and it took less than three weeks to become a major player in the country. It is also good that the delta diversity has passed and strengthened the UK, health officials said there.

Do vaccines work against omicron?

Experts have expressed concern that mutations could allow you to avoid other antibodies produced by Covid vaccines.

Previous laboratory studies show that it may be somewhat resistant to vaccines, although it may not completely prevent it. Further research is needed, however, to understand what the original findings mean in real-world settings.

An analysis released Tuesday by the South African director of health care found that two shots of the Pfizer-BioNTech vaccine were 70 percent effective in preventing hospitalization with the omicron variant, compared to 90 percent protection against delta diversity.

Preliminary data also found that the stimulant gun could play an important role in calculating the immune response against the omicron.

Dr Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases and President Joe Biden's senior medical adviser, said Wednesday that a powerful gun would probably not need to be modified to steer the omicron.

"Our booster vaccine works against the omicron," he said. "For now, there is no need for a specified booster."

Pfizer announced earlier this month that the third volume strongly protects against new laboratory tests - similar to the protection standards given for the first type of two-dimensional company versus the first type - although the findings should be confirmed in real-world settings.

A recent study to peer review found that China's Sinopharm vaccine, Russian Sputnik vaccine and a vaccine developed by Johnson & Johnson produced low levels of antibodies that protect the omicron. The study, led by scientists from the University of Washington and a Swiss biotech company called Humabs Biomed SA, provides the first results of how the various vaccines available around the world can withstand the ever-changing evolution.

Previous studies have been linked to earlier claims from vaccine makers that the alternative may delay immunization, but scientists have also insisted that the immune system has other tools that might work.
