WHO warns world not to overreact to new COVID variant
World races to contain new COVID threat, the omicron variant
27 Nov 2021
NEARLY TWO years into the COVID-19 pandemic, the world raced Friday to contain a new coronavirus variant potentially more dangerous than the one that has fuelled relentless waves of infection on nearly every continent.
A World Health Organization panel named the variant ‘omicron’ and classified it as a highly transmissible virus of concern, the same category that includes the predominant delta variant, which is still a scourge driving higher cases of sickness and death in Europe and parts of the United States.
“It seems to spread rapidly,”US President Joe Biden said of the new variant, only a day after celebrating the resumption of Thanksgiving gatherings for millions of American families and the sense that normal life was coming back at least for the vaccinated.
In announcing new travel restrictions, he told reporters, “I’ve decided that we’re going to be cautious.”
Omicron’s actual risks are not understood. But early evidence suggests it carries an increased risk of reinfection compared with other highly transmissible variants, the WHO said. That means people who contracted COVID-19 and recovered could be subject to catching it again. It could take weeks to know if current vaccines are less effective against it.
In response to the variant’s discovery in southern Africa, the United States, Canada, Russia and a host of other countries joined the European Union in restricting travel for visitors from that region, where the variant brought on a fresh surge of infections.
Medical experts, including the WHO, warned against any overreaction before the variant was thoroughly studied. But a jittery world feared the worst after the tenacious virus triggered a pandemic that has killed more than 5 million people around the globe.
Omicron has now been seen in travellers to Belgium, Hong Kong and Israel, as well as in southern Africa.
There was no immediate indication whether the variant causes more severe disease. As with other variants, some infected people display no symptoms, South African experts said. The WHO panel drew from the Greek alphabet in naming the variant omicron, as it has done with earlier, major variants of the virus.
Even though some of the genetic changes appear worrisome, it was unclear how much of a public health threat it posed. Some previous variants, like the beta variant, initially concerned scientists but did not spread very far.
