What is Omicron variant world scurries to contain a new variant of concern?

On November 26, 2021, the WHO appointed a separate B.1.1.529 alternative concern, called Omicron, on the advice of WHO’s Technical Advisory Group on Virus Evolution (TAG-VE).

This decision was based on the evidence presented in TAG-VE that Omicron has a number of changes that may affect its behavior, for example, how easily it spreads or the severity of the disease it causes. Here is a summary of what is currently known

What is Omiron ?

Researchers in South Africa and around the world are conducting studies to better understand the many aspects of Omicron and will continue to share the findings of this study as it becomes available.

Omicron discovered in South Africa this week, is feared to have the highest number of spike conversions ever seen. It has been classified as a separate concern by the World Health Organization (WHO). It has also been identified in Botswana, Belgium, Hong Kong, and Israel.

Transmissibility

It is not yet clear whether Omicron is highly contagious (e.g., easily spread from person to person) compared to other alternatives, including Delta. The number of people diagnosed with the virus is increasing in the affected areas of South Africa, but epidemiologic research is underway to determine whether it is due to Omicron or other factors.

Severity of disease

It is not yet clear whether Omicron infection causes a much worse disease compared to other strains, including Delta. Preliminary data suggest an increase in hospital admissions in South Africa, but this may be due to an increase in the number of people infected

Rather than the result of a particular infection with Omicron. There is currently no information that suggests that Omicron-related brands are different from those of other brands.

The diseases previously reported were among university students — young people who are prone to soft tissue — but understanding the severity of the Omicron variant will take days to a few weeks.

All of the variants of COVID-19, which include the Delta variants that dominate the world, can cause serious illness or death, especially for the most vulnerable, so prevention is always important.

What is the new coronavirus called?

The World Health Organization (WHO) has declared a new type of “troublesome” coronavirus and named it Omicron. It had high genetic mutations, and preliminary evidence raises the risk of re-infection, says WHO

Effectiveness of prior SARS-CoV-2 infection 

Preliminary evidence suggests that there may be an increased risk of re-infection with Omicron (i.e., people who have previously had COVID-19 may re-infect more easily with Omicron), compared to other alternative concerns, but the information is limited. More information on this will be available in the coming days and weeks.

Vaccination effectiveness:

WHO is working with technology partners to understand the potential impact of this variation in our existing resistance estimates, including vaccines. Vaccines are always important in reducing serious illnesses and deaths, including resistance to the rotating diversity, Delta. Current vaccines are still effective against serious illness and death.

Current testing performance:

The most widely used PCR tests continue to detect infections, including Omicron infection, as we have seen with other types as well. Research is underway to determine whether there are implications for other types of tests, including rapid screening for antigen detection.

Current therapeutic efficacy:

Corticosteroids and IL6 Receptor Blockers will still be effective in treating patients with severe COVID-19. Other treatments will be tested to see if they are still effective in terms of mutations in the various viral components of Omicron.

Studies are ongoing

Currently, WHO is working with a large number of researchers around the world to better understand Omicron. Ongoing or ongoing research includes viral load testing, risk of infection (including symptoms), the efficacy of vaccines and diagnostic tests, and treatment success.

WHO encourages countries to contribute to the collection and sharing of hospitalized patient data through the WHO COVID-19 Clinical Data Platform to quickly define clinical features and patient outcomes.

More information will appear in the coming days and weeks. The WHO TAG-VE will continue to monitor and evaluate the data as it becomes available and evaluate how genetic mutations in Omicron alter the behavior of the virus.

Recommended international actions

With Omicron designated as a variant of Concern, there are a number of steps the WHO recommends for countries to take, including improving monitoring and follow-up cases; genetic sequence sharing of publicly available information, such as GISAID; reporting initial cases or clusters to WHO; conducting field research and laboratory tests to better understand whether Omicron has different transmission or disease characteristics, or affects the effectiveness of vaccines, treatments, diagnoses or public health and social measures. Further details on the announcement dated 26 November.

Countries should continue to use effective public health methods to reduce the distribution of COVID-19 as a whole, using risk analysis and a science-based approach. They should increase certain public health and medical powers to control the increase in cases. The WHO provides countries with support and guidance in both readiness and response.

In addition, it is imperative that inequalities in access to COVID-19 vaccines be addressed promptly to ensure that vulnerable groups everywhere, including health workers and the elderly, receive their first and second doses, as well as equal access to treatment and diagnosis.

Recommended actions for people

The most effective measures people can take to reduce the spread of the COVID-19 virus to maintain a real distance of at least one meter from others; wear a suitable mask; open windows for air conditioning; avoid areas where the air is not clean or crowded; keep hands clean; coughing or sneezing in the curved elbow or muscles; and be vaccinated when it is their turn.

WHO will continue to provide updates as more information becomes available, including the following TAG-VE meetings. In addition, details will be available on WHO’s digital communication and communication platforms.
