There are three main reasons for this, explains Kovid-19 technical lead and epidemiologist Maria van Kerkhov at the WHO.
This variant has mutations that are easily accessible to human cells.
Even after being vaccinated, the chances of re-infection with the virus are high. This is called the “immunity escape”.
Omicron develops in the upper respiratory tract. That is, omicran replicas are formed in the nose, nasal cavity, and throat. Therefore this virus is easily spread. Other variants, including delta, develop in the lower respiratory tract, i.e., the lungs.
The Kovid Vaccine Hub portal states that it is difficult to predict how fast Omicron will spread compared to other variants. However, the UK Health Security Agency estimates that it could be two to three times higher than Delta.

2. What are the properties of Omicron?
According to a study by Joe Kovid Symptom led by Tim Specter, an epidemiologist at King’s College London, the Omicron variant features seen so far are:
Runny nose
Headache
Fatigue (Mild or Severe)
Sneezing
Sore throat
The National Health Service (NHS) in the UK has suggested that symptoms usually appear when a cow is infected. They are ..
Cough (frequent or sudden onset)
Fever
Taste, not knowing the smell
3. Is the Omicron shorter than the Delta variant with milder features?
The Centers for Disease Control and Prevention (CDC) in the United States says more data is needed to determine whether Omicron is depleting or lethal.
However, there are some indicators to suggest that in some cases omicran may cause mild disease symptoms. However, in some cases the disease can be severe and even fatal. It can be exacerbated, especially in those who have not been vaccinated.
Compared to the Delta, Omicron infected people have a one-third chance of being hospitalized, according to a report released by the UK Health Security Agency on December 31.
Lorena Garcia, an epidemiologist in the Department of Public Health Sciences at the University of California, Davis, said the omega-3 properties may be different for those who have been vaccinated and those who have not.
“Both doses of the vaccine and those given in the booster dose may have milder symptoms. Those who do not get the vaccine are more likely to develop the disease. Hospital milk can be fatal,” Garcia said.
However, the WHO warns that Omicron should not be considered a mild disease.
“Although the severity of Omicron disease is lower than that of the Delta, it cannot be identified as a mild variant,” WHO Director Tedros Adhanam warned in early January.
“Like the previous variants, Omicron also caused hospitalizations and casualties,” he said. Ignacio Lopez-Goni, a professor of microbiology at the University of Navarre in Spain, explained in an article on December 28 that those who received both doses of the vaccine would not need to be hospitalized for omega-3.
However, according to a January 7 MIT / Harvard University study, neither Pfizer nor Moderna’s do produce “antibodies that detect or neutralize omicran”. However, the booster dose could “enhance protection against omicran”.
Andrew Lee, a professor of public health at the University of Sheffield in England, said the data showed that the effects of the Pfizer or estrogen generic vaccine on Omicron were limited. However, the booster dose is described as increasing protection.
Lee suggested that Omicron could be infected despite being vaccinated. This is because vaccines do not prevent coronavirus. Can only help control the severity of the virus.
“Omicron further emphasizes the importance and necessity of vaccines and booster doses,” the CDC said.
The WHO panel on January 11 suggested that the Kovid-19 vaccines need to be updated to take effect against newer variants such as Omicron.
