The World Health Organization predicts three possible pathways for the virus in 2022, including the worst: the arrival of a new variant that is “more virulent” than the previous one.
More than 10 million people were infected last week and 45,000 people died, according to figures sent to the World Health Organization. But the number is certainly much higher.
“Based on what we know now, the most likely scenario is that the virus will continue to develop, but the severity of the disease it causes will decrease as the virus continues to evolve. Immunity increases thanks to vaccination and infections,” General Tedros Adhanom Ghebreyesus, General Tedros Adhanom Ghebreyesus, explained at a press conference.
Another scenario is the emergence of several new, but less dangerous variants. As we have seen since mid-March, new peaks of infection can arise.
in the worst case
The WHO worst-case scenario produces a new variant that is more virulent than the variant that has caused millions of deaths for more than two years. “In light of this new threat, the protection of the population, thanks to a previous vaccination or infection, against serious forms of illness or death will rapidly diminish,” said the director-general of the World Health Organization.
This would require an adaptation of existing vaccines, as protection of the population would not be guaranteed against a more worrisome and transmissible variant of Omicron or BA.2. If this is not the preferred scenario, caution is advised.
