Shafaq news/t he World Health Organization said on Tuesday it was concerned that the novel coronavirus spread was being driven by people in their 20s, 30s and 40s, many of which were unaware they were infected, posing a danger to vulnerable groups.
WHO officials said this month the proportion of younger people among those infected had risen globally, putting at risk vulnerable sectors of the population worldwide, including the elderly and sick people in densely populated areas with weak health services.
“The epidemic is changing,” WHO Western Pacific regional director, Takeshi Kasai, told a virtual briefing. “People in their 20s, 30s and 40s are increasingly driving the spread. Many are unaware they are infected.”
“This increases the risk of spillovers to the more vulnerable,” he added.
“What we are observing is not simply resurgence. We believe it’s a signal that we have entered a new phase of pandemic in the Asia-Pacific,” Kasai said.
He said countries were better able to reduce disruption to lives and economies by combining early detection and response to manage infections.
While mutations had been observed, the WHO still saw the virus as “relatively stable”, Kasai said.
WHO also reminded drug makers to follow all necessary research and development steps when creating a vaccine.
Earlier, the Russian Ministry of Health announced the production of the Covid-19 vaccine "Sputnik V," which was developed by the "Gamaleya" National Center, according to "Interfax" news agency.
Russia's announcement to register a vaccine that provides "sustainable immunity" against the virus, sparked a criticism in a number of countries in the world, and concerns among some experts.
Some experts also expressed concern about Moscow's decision to grant approval for the vaccine before completing the final trials.
US President Donald Trump had expressed his hope that the Russian vaccine would be effective, stressing to comply with all practical rules in the drug industry.
