What Is Omicron? – Detailed Analysis Of SARS-CoV-2 Omicron Variant


What Is Omicron?

SARS-CoV-2, the virus that causes COVID-19, has a new variation called Omicron. On November 24, 2021, the variation was first reported to the World Health Organization (WHO) by South Africa. The WHO identified it as a variation of concern on November 26, 2021, and named it after the omicron. The variation contains an exceptionally high number of mutations, many of which are unique and impair the spike protein targeted by most vaccines at the time of Omicron’s discovery.

Is Omicron Variant Dangerous?

The omicron variety of the coronavirus illness (Covid-19) includes 32 mutations, according to researchers. The spike protein of the coronavirus has such mutations. The spike protein is used by the virus to adhere to our cells and infect us. The alterations in omicron may make it simpler for the virus to infect us via ACE-2 receptors, according to microbiologists. It’s also plausible that the new variety evades human immune systems better than earlier forms, according to the researchers.

As a consequence, scientists are looking at three particular mutations in a Furin cleavage site. Furin is an enzyme required for viruses like SARS-CoV-2, as well as influenza, dengue fever, HIV, and many others, to completely operate – it essentially aids the virus’s development as a disease in your body. As a result, scientists believe that if omicron finds it simpler to infect humans and become fully functioning, it will spread more quickly – it will have a greater transmission rate than previous variants.

How Effective Are Vaccines Against Omicron?

Scientists claim that additional data is needed before they can publish any findings. Moderna’s chief executive officer has also cautioned that the efficacy of existing Covid vaccinations against omicron might suffer a “substantial decline.” Stephane Bancel, on the other hand, couldn’t specify how much. “We have to wait for more data,” Bancel said. However, every scientist I’ve spoken with says, This isn’t going to be good.

On the other end, South Africa’s top infectious diseases specialist stated at a news briefing on Monday that current vaccinations were likely effective against omicron. “Despite the uncertainty,” the WHO concluded in a study released on November 28, “it is fair to believe that presently existing vaccinations give some protection against severe sickness and mortality” caused by the omicron strain. Everyone should take a dose of both vaccines as soon as possible to protect themselves from the new variant.

Which Drugs To Take For Omicron?

Drugs to treat Covid-19 are desperately needed, The Food and Drug Administration’s expert panel decided on Tuesday to recommend that one of these medications be approved for those who are at high risk of severe Covid-19. The medicine, molnupiravir, manufactured by Merck, isn’t without flaws. It can reduce the chance of hospitalization and mortality by a small amount, but there are certain safety concerns, particularly for women who may get pregnant.

Pfizer has also submitted an antiviral medication to the Food and Drug Administration for assessment. So far, the medicine appears to be more promising, with early evidence indicating that it can lower the risk of Covid-19-related hospitalization or mortality by 89%. but it is highly recommended not to take any medicine without a doctor’s prescription.

Symptoms Of Omicron Variant

These are the identified symptoms of the SARS-CoV-2 omicron variant –

Most Common Symptoms:

  • Fever, Cough, Tiredness (High), Loss of taste or smell

Less Common Symptoms:

  • Sore throat (High), Headache, Aches & pains, Diarrhea, A rash on the skin, Red or irritated eyes
Serious Symptoms:
  • Difficulty breathing, Loss of speech or mobility, Chest pain

Safety Tips For Omicron Variant

Scientists believe the virus is more transmissible than the delta form, although it is less lethal. Currently, the best approach to be safe is to adhere to all WHO and government-mandated safety measures.

  • Get vaccinated (Both 1 & 2) if you haven’t
  • Maintain proper physical distance in a crowd
  • Avoid crowds as much as possible by limiting your time outside
  • Hand hygiene and respiratory etiquette should be followed
  • When going out or meeting someone from the outside, wear a mask
  • Don’t ignore any signs of illness (fever, weakness, sore throat)
  • Don’t panic and contact your doctor in case of any emergency
