What exactly is Omicron?
Omicron is a variant of SARS-CoV-2 virus, which was designated by WHO on 26 November 2021. This variant is wildly different from earlier versions of the coronavirus.
It is not very clear whether Omicron can easily spread from person to person or not. Omicron also likely carries a lower chance of getting seriously ill.
But what is the severity of this variant? Does this variant cause less severe disease than the variants that have come before it?
How severe is Omicron?
It is not yet clear whether infection with Omicron causes more severe disease compared to infections with other variants, including Delta.
Rates of hospitalization of cases are increasing everywhere but this may be due to increasing overall numbers of people becoming infected, rather than a result of specific infection with Omicron.
All variants of COVID-19, including the Omicron and Delta variant that is dominant worldwide, can cause severe disease or death. So, it is very important for people to take necessary precautions.
What are the symptoms of Omicron?
Although this variant of corona virus - Omicron has shown not much identifiable symptoms but according to an analysis there are four most common symptoms shown by the omicron variant and those are:
Nausea or vomiting
These are the common symptoms of Omicron but according to the Centers for Disease Control and Prevention (CDC), people might experience different symptoms or combinations of symptoms.
Loss of smell and taste are also identified as Omicron symptoms but according to the self-reported data, it appears to be less common among people recently testing positive.

Do COVID-19 vaccines protect against the Omicron variant?
Vaccines of Covid-19 will not be of much help against Omicron but they still seem to provide a significant degree of protection against serious illness from Omicron, which is the most crucial goal.
There are few vaccine shots that, when reinforced by a booster, appear to have initial success at stopping infections, but these vaccines are unavailable in most of the world.
However, vaccine protection is also by antibodies as well as by immunity, which is expected to be relatively better preserved. Hence, vaccines are expected to still offer protection against severe disease.
Omicron is a variant of coronavirus, so it seems to be a deadly virus for us. Although, Covid-19 vaccines will somehow help in protecting us from Omicron infections, we need to make sure that we take enough precaution for ourselves.
