World Health Organization provides update on what to expect from Covid-19 in 2022

The World Health Organization (WHO) has provided an updated ‘strategic plan for preparedness, willingness and response’ to Covid-19, highlighting various scenarios for how the 2022 pandemic will evolve.

Tedros Adhanom Ghebreyesus, Director – General of the United Nations Office for International Health, said in a briefing on Wednesday (March 30) that the third strategic plan for Covid-19, “could and should be our last”.

“It sets out three possible scenarios for how the pandemic could evolve this year. From what we now know, the most likely scenario is that the virus will continue to evolve, but the severity of the disease that causes it decreases over time as immunity increases due to vaccination and infection.

“Periodic spikes in cases and deaths can occur as immunity declines, which can periodically stimulate vulnerable populations,” he said.

At best, the DG said less serious variants could arise, and boosters like new formulations of faxes would not be necessary.

“In the worst case, a more virulent and highly transmissible variant emerges. Against this new threat, the protection of people against serious illness and death, whether from prior vaccination or infection, will rapidly decline,” he said.

To address this situation, it would be necessary to significantly change the current vaccines and ensure that they reach the people most vulnerable to serious illness, Ghebreyesus added.

He said ending the acute phase of the pandemic in 2022 would require countries to invest in five core components:

  • Public health surveillance, laboratories, and intelligence;
  • Vaccination, public health and social measures, and communities involved;
  • Clinical care for Covid-19, and resilient health systems;
  • Research and development, and equal access to tools and supplies;
  • Coordination, as the response shifts from an emergency mode to long-term respiratory disease management.

“We have all the tools we need to bring this pandemic under control: we can prevent transmission with masks, distance, hand hygiene and ventilation. And we can save lives by ensuring that everyone has access to tests, treatments and vaccines. “Forensic vaccination remains the single most powerful tool we have to save lives,” the DG said.

The WHO said that efforts to vaccinate 70% of each country’s population remain essential to bring the pandemic under control “Many high and middle income countries have achieved this goal, and have seen a decoupling between cases and deaths. , “said Ghebreyesus.

“Even if some high – income countries now roll out fourth doses to their populations, one third of the world’s population still needs a single dose, including 83% of Africa’s population.

“This is not acceptable to me, and it should not be acceptable to everyone.”

South Africa’s official death toll from the coronavirus exceeded the 100,000 mark this week. An additional 44 deaths due to the disease have been reported, bringing the total to 100,020, the National Institute of Communicable Diseases said in a statement on Wednesday.

Scientists advising the government have said they expect the fifth wave of infections to hit by the end of May.
