Company | Pandemic 2022: the worst scenario of the WHO predicts a new more virulent variant

The most likely scenario in the eyes of the UN body is based on a gradual decrease in the severity of the disease caused by the virus, thanks to better immunity of the populations.

The WHO has outlined the three paths that could be taken the covid-19 pandemic this year and the worst of cases is considering a new variant more virulent than those that already caused millions of deaths for more than two years. However, the most likely scenario in the eyes of the UN organization is less dramatic. He is counting on a gradual decline in the severity of the disease caused by the virus, thanks to better population immunity.

Possible spikes in infection

L’WHOSE published on Wednesday a revised version of its strategic plan to combat the pandemic. Its CEO, Tedros Adhanom Ghebreyesus, hopes it will be the last, while the disease, which was first detected in China by the end of 2019, it had spread throughout the world, killing more than 6 million people, according to official figures, but undoubtedly many more due to a lack of accurate accounting. “Based on what we know now, the most likely scenario is that the virus will continue to evolve, but the severity of the disease it causes will decrease as immunity increases thanks to vaccination and infections.”explained doctor Tedros, during a press conference.

Spikes in infections may recur from time to time as immunity drops again, requiring booster shots, especially for vulnerable people. “Ideally, we would see less severe variants emerge and there will be no need for new booster dose formulations and vaccines.”to combat them added the head of the UN organization.

“Highly Transmissible Virus”

Plus “In the worst case, a more virulent and highly transmissible virus emerges. Faced with this new threat, the protection of populations -thanks to previous vaccination or infection- against severe forms of the disease or death will be rapidly reduced”, explains Dr. Tedros. It would then be necessary to significantly modify existing vaccines and ensure that they are distributed to the most vulnerable people. Maria Van Kerkhove, who oversees the fight against COVID-19 for the WHO noted that even in its current form “the virus still has a lot of energy”.

Last week, more than 10 million people were infected and 45,000 died, according to figures sent to the WHO. But the number is certainly much higher. Many countries that have lifted most health restrictions to control the pandemic have also drastically reduced the number of tests at the same time, making it very difficult to measure the evolution of the pandemic.
