BEIJING – China has yet to detect any dangerous Covid-19 mutations in the six weeks since the virus was unleashed on the country’s 1.4 billion people after the abandonment of the rigid curbs that held the pathogen largely at bay.

Fresh global concerns over novel variants have taken hold in recent weeks, with countries imposing restrictions on Chinese travellers as the virus swamped the world’s most populous country with breathtaking speed. “With Omicron, our Covid wards are still mostly empty,” said Alex Sigal, a virologist at the Africa Health Research Institute in Durban. “At least part of that has to do with the variant, and not only a buildup of immunity. With a new variant, you don’t know what will happen.”has ramped up genetic sequencing efforts.
