Covid severity will reduce but…: WHO chief on 3 scenarios how pandemic evolves


World Health Organisation (WHO) chief Tedros Adhanom Ghebreyesus notified that the severity of the COVID will reduce over time but, warned that we need to remain cautious and protected in case a more virulent and highly transmissible COVID19 virus variant emerges. Further, he laid out three possible scenarios for how the pandemic will evolve this year. This comes at a time when the entire world is witnessing a massive COVID surge fueled by the Omicron BA.2 subvariant. 

3 ways how the COVID pandemic will evolve this year:

During a briefing on Wednesday, WHO Director-General Tedros Adhanom Ghebreyesus pointed out that based on what is known now, the most likely scenario is that the COVID-19 virus continues to evolve, but the severity of disease it causes reduces over time as immunity increases due to vaccination and infection.  

“Periodic spikes in COVID19 cases and deaths may occur as immunity wanes, which may require periodic boosting for vulnerable populations. In the best-case scenario, we may see less severe variants emerge, and boosters or new formulations of vaccines won’t be necessary.”

In the worst-case scenario, a more virulent and highly transmissible #COVID19 virus variant emerges. Against this new threat, people’s protection against severe disease and death, either from prior vaccination or infection, will wane rapidly, he added.

And to address this situation, it is required to significantly alter the current COVID19 vaccines and make sure they get to the people who are most vulnerable to severe disease

The updated Strategic Preparedness, Readiness and Response Plan sets out the strategic adjustments that every country needs to make to address the drivers of SARS-CoV-2 transmission, lessen the impact of COVID, and end the global emergency.
