What is the Omicron variant?
The Omicron variant of COVID-19 has been called a variant of concern by WHO based on the evidence that it has several mutations that may have an impact on how it behaves. There is consistent evidence that Omicron is spreading significantly faster than the Delta variant in countries with documented community transmission, with a doubling time of 2-3 days. The overall risk related to this new variant remains very high.
How did the Omicron variant develop?
When a virus is circulating widely and causing numerous infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more opportunities it has to undergo changes.
New variants like Omicron are a reminder that the COVID-19 pandemic is far from over. It is therefore essential that people get the vaccine when available to them and continue to follow existing advice on preventing the spread of the virus, including physical distancing, wearing masks, regular handwashing and keeping indoor areas well ventilated.
It is also crucial that vaccines and other public health measures are accessible everywhere. Vaccine inequity leaves lower income countries – many of them in Africa – at the mercy of COVID-19. Well-supplied countries must urgently deliver the doses they promised.
Where is the Omicron variant present?
Omicron has now been detected in most countries, after the variant was first detected in November 2021.
