What is Omicron and what are the symptoms?
The WHO gives Covid variants names based on letters in the Greek alphabet for two main reasons.
First, it is to make them easily identifiable and clear to the public. Second, it is to prevent the stigmatization of countries or places where they first emerged. Tell that to the organizations that called it the “South African variant”.
WHO designated the variant, B.1.1.529, a variant of concern and named it Omicron. This decision was based on the evidence that showed Omicron has several mutations that could impact how it behaves.
What is the severity of the disease?
It is not yet clear whether infection with Omicron causes more severe disease compared to infections with other variants, including Delta.
According to preliminary data, there is an increase in rates of hospitalization in the country. However, the WHO says this may be due to increasing overall numbers of people becoming infected, rather than a result of specific infection with Omicron.
What are the symptoms of the Omicron variant?
There is no information to suggest that symptoms associated with Omicron are different from those from other variants, says WHO.
According to a Bloomberg report, patients complained of fatigue, head and body aches and occasional sore throats and coughs, said the chairperson of the South African Medical Association, Angelique Coetzee.
It is worth noting that all variants of Covid-19, including the Delta variant that is dominant worldwide, causes severe disease or death.
Is Omicron more transmissible?
It is unclear at this stage whether Omicron is more transmissible (more easily spread from person to person) compared to other variants.
WHO says the number of people testing positive has risen in areas of South Africa affected by this variant, but studies are under way to understand if it is because of Omicron or other factors.
What is the effectiveness of vaccines?
WHO is working with partners to understand the potential impact of Omicron variant on countermeasures, including vaccines.
Vaccines remain critical to reducing severe disease and death, including against the dominant circulating variant, Delta. They have proved to be effective against severe disease and death.
