Geneva, May 25 (EFE).- No country is likely to achieve herd immunity against Covid-19 in the near future, the World Health Organization said on Tuesday.
“Studies indicate that it takes more than 80% of a community to be immunized to interrupt transmission,” the WHO’s director of health emergencies, Mike Ryan, said during the World Health Assembly in Geneva.
“But data from serological data around the world reveal that no country has acquired this level of natural immunity,” he added. “A substantial part of the world’s population remains susceptible to infection”.
He highlighted the importance of maintaining the precautionary measures against Covid-19, including physical distancing, wearing masks and good ventilation as well as test and contact tracing to tackle the virus.
“Having relaxed the measures prematurely contributed to the flare-ups we saw in 2020 and in the first quarter of this year,” he added.
The pandemic situation is “fragile and volatile” and coronavirus cases and deaths are underreported, the WHO said.
Twenty percent of symptomatic patients experience severe to critical cases, while the symptoms developed by the rest range between mild to moderate, data provided by countries show.
On average, 16% percent of severe to critical patients die from the disease, a decrease compared to the 40% average recorded in the early stages of the pandemic. EFE
