CHICAGO - As the devastating Delta variant surge eases in many regions of the world, scientists are charting when, and where, COVID-19 will transition to an endemic disease in 2022 and beyond, according to Reuters interviews with over a dozen leading disease experts.
The agency's view is based on work with disease experts who are mapping out the probable course of the pandemic over the next 18 months. By the end of 2022, the WHO aims for 70% of the world's population to be vaccinated. Europe has been an exception, with Delta wreaking new havoc in countries with low vaccination coverage such as Russia and Romania, as well as places that have lifted mask-wearing requirements. The variant has also contributed to rising infections in countries such as Singapore and China, which have high rates of vaccination but little natural immunity due to much stricter lockdown measures.
"We'll go into a very modest winter increase" in COVID-19 cases, he said. "If there's no major new variants, then COVID starts to really wind down in April." Imperial College's Ferguson expects above-average deaths in the UK from respiratory disease due to COVID-19 for the next two-to-five years, but said it is unlikely to overwhelm health systems or require social distancing be reimposed.
