Ómicron doubles its cases every 2 or 3 days, according to the WHO

The omicron variant of the coronavirus causing COVID-19 has already been detected in 110 countries, and continues to spread exponentially, doubling its cases in the communities where it is transmitted in a matter of two or three days, highlighted today the World Health Organization (WHO).
In its update of the technical report on the omicron variant, the WHO clarified that the rates of contagion of it are falling in one of the South African provinces where it was first detected.
Data from outbreaks in South Africa, the UK, and Denmark seem to suggest a lower risk of hospitalization in patients who contract the omicron variant compared to delta, although the WHO takes these data with caution.
Other preliminary studies in different countries indicate a reduction in the protection of vaccines such as AstraZeneca or Pfizer-BioNtech compared to the omicron variant, although in the case of the latter a booster dose seems to increase its effectiveness.
