Covid – Omicron: “From the best case” to “a new threat”, the WHO considers three different scenarios for the epidemic in 2022

The World Health Organization considers the hypothesis of a “more virulent” and “highly transmissible” variant.

This Wednesday, theWorld Health Organization (WHO) convey your “Updated strategic preparedness and response plan for the COVID-19. This is our third strategic plan, and it could and should be our last.”explains the institution in a press release posted on their website.

The WHO lists three scenarios that the epidemic could evolve during the rest of 2022.

In the best case…

“Based on what we know now, the most likely scenario is that the virus continues to evolve, but the severity of the disease it causes decreases over time asimmunity increases due to vaccination and of theinfectionwrites the WHO.

However, “periodic peaks of case and death can occur as immunity declines, which may require periodic boosting for vulnerable populations”.

Then two scenarios can arise: “At best, we could see emerging variants less severe, with withdrawals or new formulations of vaccines That won’t be necessary.”

In the worst case…

“In the worst case, a more virulent and highly transmissible variant emerges. Before this new threat, people’s protection against serious illness and death, whether from prior vaccination or infection, will rapidly diminish. To remedy this situation, current vaccines would need to be significantly modified and ensure that they reach those most vulnerable to serious illness..

To end the acute phase of pandemic this year, the WHO urges countries “invest in five essential components” :

– Surveillance, laboratories and intelligence in public health.

– Vaccination, public health and social measures, and engaged communities.

– Clinical care for COVID-19 and resilient health systems.

– Research and development and equitable access to tools and supplies.

– Coordination, as the response shifts from emergency mode to long-term management of respiratory diseases.

“Striving to vaccinate 70% of the population in each country remains essential to contain the pandemic, prioritizing health workers, the elderly and other risk groups”remember the WHO.
