WHO warns Delta threatens to mutate into a global fight against COVID-19 results
Thứ Bảy, 31/7/2021| 9:48The World Health Organization (WHO) on July 30 warned that the world risks losing its achievements against COVID-19 when the Delta variant spreads.
WHO Director-General Tedros Adhanom Ghebreyesus said that COVID-19 infections have increased by 80% in the past 4 weeks in most regions of the world. COVID-19 deaths in Africa - where only 1.5% of the population is vaccinated - increased by 80% during this period. "The hard-won gains are in danger or lost, and health systems in many countries are overwhelmed," warned Tedros. According to WHO, the Delta variant was detected in 132 countries, becoming the dominant strain globally.
Mike Ryan, WHO's top emergencies program specialist said: "The vaccines approved by WHO all provide significant protection against variants, including the Delta variant, in preventing severe disease. and hospitalized". He stressed that the world is continuing to fight the SARS-CoV-2 virus, but the difference is that this virus has become faster, better adapted to spread.
Maria van Kerkhove, WHO's expert group leader on COVID-19 said that by far the Delta variant is the most contagious with about 50% higher transmissibility than the Sars-CoV-2 strain that first appeared in Vietnam, in China late 2019. Some countries have seen increased hospitalizations, but higher mortality rates have not been seen from the Delta variant, she said. On July 30, Japan said it would extend a state of emergency to three prefectures near the Olympic host city Tokyo and Osaka prefecture to the west as a spike in COVID-19 cases in the capital and across the country cast a shadow over the Olympics. Dr. Ryan noted that out of 10,000 new COVID-19 infections in Japan in the past 24 hours, Tokyo recorded more than 3,000. "The Olympics are part of that common landscape and the risk management applied to the Olympics is extremely comprehensive," he said.
