The Delta variant of Covid-19 is a warning to the world to suppress the virus quickly before it mutates again into something even worse, the WHO said Friday. The highly-transmissible variant, first detected in India, has now surfaced in 132 countries and territories, the World Health Organization said. Though Delta has shaken many countries, Ryan said proven measures to bring transmission under control still worked -- notably physical distancing, wearing masks, hand hygiene and avoiding long periods indoors in poorly ventilated, busy places. "They are stopping the Delta strain, especially when you add in vaccination," he said. Instead, those nations, "in the face of the Delta variant -- they're going to pay a very, very different price as a result".
