Is Omicron Dangerous Than Covid 19: Facts and Myths about Omicron
The WHO’s Technical Advisory Group on Virus Evolution recommended that the B.1.1.529 variant be classified as a variant of concern and given the working title of Omicron on November 26, 2021. (TAG-VE). The TAG-decision VE’s was based on the evidence that Omicron has several mutations that may have an impact on how it behaves, for example, on how easily it spreads or the severity of illness it causes.. The
Many studies are being conducted in South Africa and around the world in an effort to better understand Omicron, and these findings will be shared as they are available.
Transmissibility: If Omicron is more contagious than other strains, including Delta, it is not yet known whether it is more transmissible. It’s unclear whether Omicron or other factors are to blame for an increase in the number of people testing positive in South African regions affected by this variant.
Severity of disease:
Infection with Omicron may cause more severe disease than infections with other strains, including Delta, but this is not yet known.
Initial data suggests that hospitalisation rates in South Africa have increased, but this may be due to an increase in overall infection rates, rather than a specific infection with Omicron, as previously thought.
There is currently no evidence that Omicron’s symptoms differ from those of other variants of the disease.
Younger people with more mild disease are the first to be infected, but it will take days to weeks to determine the severity of the Omicron variant.
In the most vulnerable populations, all COVID-19 variants, including the globally prevalent Delta variant, can cause serious illness or death, so prevention is always a priority.
Effectiveness of prior SARS-CoV-2 infection
Preliminary evidence suggests there may be an increased risk of reinfection with Omicron (ie, people who have previously had COVID-19 could become reinfected more easily with Omicron), as compared to other variants of concern, but information is limited. More information on this will become available in the coming days and weeks.
People who previously had COVID-19 may be more susceptible to reinfection with Omicron than with other variants of concern, based on preliminary evidence, but more research is needed. In the days and weeks to come, we’ll have more information on this.
This variant’s potential impact on our current countermeasures, including vaccines, is being studied by WHO in conjunction with technical partners. In the fight against the dominant circulating variant, Delta, vaccines remain critical. The current vaccines are still effective in preventing death and life-threatening illness.
The widely used PCR tests continue to detect infection, including Omicron, as we have seen with other variants as well. Rapid antigen detection tests and other types of tests are being studied to see if there is any impact.
Current treatments are still effective in treating patients with severe COVID-19, including corticosteroids and IL6 Receptor Blockers. It will be tested to see if other treatments work as well as before because of the Omicron variant’s changes to the virus itself.
