(ANSA) - ROME, 12 JAN - "Even if Omicron causes a less serious disease than Delta, it remains a dangerous virus, especially for those who are not vaccinated".
This was underlined by WHO Director General Tedros Adhanom in the briefing on the pandemic in Geneva.
Recalling that "the huge spike of infections" in the world "is led by Omicron, which is rapidly replacing Delta in almost every country."
And "in the past week, more than 15 million new Covid cases have been reported around the world, by far the largest number of cases reported in a single week".
