Omicron: Symptoms, treatments, vaccine effectiveness

the World Health Organization (WHO) had designated variant B.1.1.529 as of concern on the advice of WHO Technical Advisory Group on Virus Evolution (TAG-VE).

Based on the evidence to date, Omicron itself has had several mutations that may impact the behavior of the virus and its ease of spread or the severity of the disease it is likely to cause.

What do we know so far?

According to the WHO, researchers in South Africa and around the world are conducting studies to better understand many aspects of Omicron and will continue to share the results of these studies as they become available.

It is still not clear whether the variant is more transmissible than Delta and Beta, but the number of positive cases in South Africa has increased for this reason.

Severity of the disease

It is not yet clear whether infection with Omicron causes more serious illness compared to infections with other variants, including Delta. However, the WHO reveals that preliminary data suggests that there is an increase in hospitalization rates in South Africa, but this may be due to the increase in the overall number of people infected, rather than an infection. specific by Omicron.

Symptoms of Omicron

There is currently no information to suggest that the symptoms associated with Omicron are any different from those of other variants, says the WHO. “The first infections reported were in college students – younger people who tend to have milder disease – but it will take days to weeks to understand the level of severity of the Omicron variant. All variants of COVID-19, including the Delta variant which is dominant in the world, can cause serious illness or death, especially for the most vulnerable people, and therefore prevention is always the key, ”says a WHO report.

Vaccine efficacy

WHO is still working with partners to understand the potential impact of this variant on our existing countermeasures, including vaccines. However, current vaccines remain effective against serious illness and death.
