A new Covid outbreak blighting China is believed to be the Omicron variant which became prevalent in the United Kingdom last year. First detected in November 2021 in South Africa, it quickly spread around the world, becoming the dominant strain of infection.
In Shanghai a new round of Covid outbreaks is feared to be Omicron - one of the most easily transferable variants of the coronavirus - with stringent lockdown measures introduced to fight it. Unlike the rest of the world which had to battle it without knowing its early warning signs, China has thousands of cases to examine to determine a course of action, Mirror reports.
Nine common symptoms associated with it were previously identified for those who have had the vaccine, with another two crucial early warning signs of the infection. Scientists from Norway last year completed a study of guests at a party in November 2021 where Covid had run riot.
