The World Health Organization states that it still does not know, due to a lack of data, whether the higher rate of transmission in highly immunized populations is due to the fact that Microns “escalate immunity, benefit from an inherently higher transmissibility or are due to a combination of two factors”

a variable Omicron The World Health Organization said on Sunday that the new coronavirus that causes COVID-19 appears to be more transmissible than the delta variant, causes milder symptoms and makes vaccines less effective.

The Omicron variant is already present in 63 countries, the World Health Organization explained in a case report released this Sunday, cited by AFP.
According to the United Nations agency, the alternative Omicron It appears to be spreading faster than the delta variant, which is still prevalent in new infections worldwide.
The fastest transmission is found not only in South Africa, where the delta variant is not common, but also in the UK, where the variant is prevalent.
WHO does not yet know, due to a lack of data, whether the higher transmission rate in highly immunized populations is due to the fact that Omicron “escapes immunity, benefits from an inherently higher transmissibility or is due to a combination of factors”.

The organization acknowledges that Micron is likely to outperform Delta where there is community transmission.
Data is still insufficient even to determine the severity of the disease caused by the new variant, although symptoms currently appear to be “mild to moderate”, both in South Africa, where Omicron was first discovered, and in Europe.
For COVID-19 vaccines, the limited data available, as well as the genetic characteristics of the omicron variant, indicate a “low level of efficacy” with respect to infection and transmission.
Several pharmaceutical companies have announced that they are already working on changing vaccines in order to cover the new alternative more effectively.
Covid-19 has killed at least 5,300,591 people worldwide, among the more than 269.02 million new coronavirus infections recorded since the beginning of the pandemic, according to the latest report from Agence France-Presse.
The respiratory disease is caused by the SARS-CoV-2 coronavirus, which was discovered in late 2019 in Wuhan, central China, and currently with variants identified in several countries.
