At what point is Omicron spreading?
It has been found in 70 countries. In Italy there are 27 detected cases (certainly only a small proportion compared to real cases). In South Africa, where it was observed in mid-November, today Omicron has replaced the Delta and represents 90% of new infections. In Britain “it is spreading at a phenomenal rate,” said the British health minister Sajid Javid.
