The Delta variant of Covid-19 is a warning to the world to remove the virus quickly before it mutates again into something even worse, the World Health Organisation (WHO) said on Friday. The highly transmissible variant was first detected in India. It has now surfaced in 132 terrains and is partly responsible for an 80% increase in coronavirus deaths in Africa over the past four weeks, the World Health Organization has said. “Delta is a warning: it’s a warning that the virus is evolving but it is also a call to action that we need to move now before more dangerous variants emerge,” the WHO’s emergencies director Michael Ryan told a press conference. WHO chief Tedros Adhanom Ghebreyesus added: “So far, four variants of concern have emerged -- and there will be more as long as the virus continues to spread.” Tedros added that on average, infections increased by 80 percent over the past four weeks in five of the six WHO regions. 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.
