The Omicron variant and its sub-strains have sparked worry in some parts of Asia and several European countries in fresh caution for world leaders and governments.
With new coronavirus strains emerging from different parts of the world, fears have grown of yet another pandemic wave approaching soon. The global coronavirus caseload topped 493.5 million on Monday, while the deaths have surged to more than 6.16 million, according to Johns Hopkins University. At least 11 billion people across the world are vaccinated against the deadly virus. Shanghai, the financial capital of China, is among the worst-hit cities in the country amid fresh surge, and it continues to reel under stringent lockdown measures as authorities extended restrictions on transportation on Tuesday to curb the spread of coronavirus infections. Meanwhile, a renewed surge of Covid-19 infections was reported in Britain, led by the Omicron variant and newly discovered mutant strain XE.
