OMICRON IS DIFFERENT II SARS-CoV-2 variant B.1.1.529 II DR MEDICAL LECTURES

Описание: The Omicron variant has now been detected in over 110 countries, mainly in Africa and Europe and spreading in Asia. International data and the experience of local cases suggest that the Omicron variant is likely to be more transmissible but less severe than the Delta variants. It is also found that vaccines, especially boosters, retain substantial protection against hospitalizations caused by Omicron.
The most accepted and commonly used method of diagnostic for SARS-CoV2 Variant is RT-PCR method. This method detects specific genes in the virus, such as Spike (S), Enveloped (E) and Nucleocapsid (N) etc to confirm the presence of virus. However, in case of Omicron, as the S gene is heavily mutated, some of the primers may lead to results indicating absence of the S gene (called as S gene drop out). This particular S gene drop out along with the detection of other viral genes could be used a diagnostic feature of Omicron. However, for final confirmation of the omicron variant genomic sequencing is required.
It is important to highlight that Omicron has been declared VOC based on the observed mutations, their predicted features of increased transmission and immune evasion, and preliminary evidence of detrimental change in COVID-19 epidemiology, such as increased reinfections. The definitive evidence for increased remission and immune evasion is awaited.
Everyone is reminded to take measures to reduce their risk of COVID-19, including proven public health and social measures such as wearing well-fitting masks, hand hygiene, physical distancing, improving ventilation of indoor spaces, avoiding crowded spaces, and getting vaccinated.
