The World Health Organization on Friday said that the Delta COVID variant, which first emerged in India last year, is a warning to the world to suppress coronavirus quickly before it further mutates again into something worse. "So far, four variants of concern have emerged -- and there will be more as long as the virus continues to spread," he said. The second wave of COVID-19 in India was triggered by the rapid spread of the Delta variant. The COVID infections due to the Delta variant have increased by 80 percent in the past four weeks in five of the six World Health Organization regions, WHO Director-General Tedros Adhanom said. "They (COVID prevention measures) are stopping the Delta strain, especially when you add in vaccination," Ryan said.
