Omigron: Five important things you need to know about the new variant of COVID-19 | Sars-cov-2 | WHO | Vaccine | nnda-nnlt | Peru

As society began to return to normal with the progress of the vaccine, one word compelled us to remember that we continue in times of epidemics: . This new variant It has activated alarms and the World Health Organization (WHO) considers it “worrying” due to its high prevalence.

This new variant has made the virus more contagious and prompted governments to take measures such as capacity reduction and restrictions on those who have not been vaccinated to prevent its rapid spread. According to the El Mundo newspaper in Spain, here are some things you need to know.

5 important things you need to know about the new variant of Govit-19, Omigran

Why is Omigran so widespread?

Mutations allow the virus to enter human cells more easily and become more infectious. When creating a new key in the hardware store, it can be very difficult to open the door, but if you use it, the key will be further refined. The same thing happened with the virus: over time it is refined. In addition, there is a very interesting fact from an initial study that omigron multiplies 70 times faster in human trachea compared to other types. This is how viruses work because their purpose is to turn them into endogenous pathogens, that is, to stay with us forever.

Why might Omigran leak some vaccines?

Vaccines against the corona virus are designed to target the spike protein, the main variant of the virus. Vaccines are not designed to identify the 32 mutations in this new variant. Fortunately, vaccines recognize some common key structures, but not all. Therefore, it can continue to spread even after vaccination. It has been said from the beginning that vaccines protect against serious infections, but not infections.

Which virus kills fewer humans?

If the virus continues to spread in large numbers, the number of victims could cause many deaths. The El Mundo newspaper explains the following: Imagine a virus that kills thirty percent of the victims, (which is a lot), and affects a thousand: 300 people will die. A virus capable of killing only 1% of the victims, but capable of infecting 100,000 people, can now be imagined: although it is less dangerous, it is highly contagious, killing thousands more than in the previous case.

Are antibodies reduced? Are we insecure before Omigron?

It is true that antibody levels decrease over time. However, we also have long-lasting cellular immunity. Any healthy person who has taken two doses should not worry that he or she is unsafe. The third dose is given first to those at risk, then to the elderly whose immune system is poor and those who respond poorly to the vaccine.

Does the third dose make sense?

Studies show that infection can be controlled only through cellular response. Studies show that a single booster dose lowers severe COVID-19 at any age and significantly enhances the neutralizing action against omigran.

What symptoms does Omigron cause?

According to preliminary studies, muscle aches, fatigue and headaches are the most characteristic omigran symptoms. There are pictures of fever and sore throat. In general, the symptoms are the same as we already know, although it is observed that in the detected cases they do not lose taste or smell.

How many variants of the SARS-COV-2 virus currently exist?

Some, but not all, are considered a “Variant of Concern” (VOC) by the WHO. We have this special list:

  1. Alpha (first detected in the UK, September 2020)
  2. Beta (South Africa, May 2020)
  3. Gamma (Brazil, November 2020)
  4. (India, October 2020)
  5. Now to Omigron.
