Omicron Variant: How fast it spreads and how dangerous it is, know everything…

According to the WHO, researchers in South Africa and around the world are conducting studies to better understand several aspects of the Omicron variant. A Right now, this is what is known:

How fast it spreads (Transmissibility)
Whether the Omicron is more communicable than many other types, including the Delta, is not yet known.

Severity of Disease

Is Omicron causing more severe disease than other types of infections, including Delta? This too is not known yet. The data suggest that hospitalization rates are increasing in South Africa, but this may be due to an increase in the total number of people infected as a result of a specific infection with Omicron. So far there is no information to suggest that Omicron’s symptoms are different from other types. All forms of COVID-19 can cause serious illness or death, especially for the most vulnerable, and thus prevention is key.

Vaccine Effectiveness

Vaccines are important for reducing serious illness and death, including the dominant circulating variant, Delta. Current vaccines remain effective against serious illness and death.


Widely used PCR tests continue to detect infection, including infection with Omicron testing, as we have seen with other variants. Studies are ongoing to determine if this has any effect on other types of tests, including rapid antigen detection tests.

effectiveness of current treatments

Corticosteroids and IL6 receptor blockers will still be effective for the management of patients with severe COVID-19. Other treatments will be evaluated to see if they are still as effective, given the changes in parts of the virus in the Omicron variant.

As concerns over Omicron remain, there are a number of actions that WHO recommends countries do, including:

– Keep track of cases and follow up to make it better.

– share genome sequences on publicly available databases such as GISAID; Reporting initial cases or clusters to WHO

– Investigate and evaluate the field to understand whether omicrons have different transmission or disease characteristics, or affect the effectiveness of vaccines, therapeutics, diagnostics, etc.

Countries should implement effective public health measures to reduce overall COVID-19 circulation using risk analysis and a science-based approach.

WHO gave suggestions to stop the spread

The most effective steps individuals can take to reduce the spread of the COVID-19 virus are:

1. Keep at least 1 meter physical distance from others

2. Wear a Mask

3. Open windows to improve ventilation

4. Avoid poorly ventilated or crowded places

5. Keep hands clean

6. get vaccinated
