China warns of further spread in latest COVID-19 flare-up

China's latest COVID-19 outbreak is increasingly likely to spread further, a health official said on Sunday, as authorities urged all regions to step up monitoring and called for a reduction in travel across provinces. China has largely contained the virus but it is determined to stamp out any sporadic local outbreaks, particularly in the run-up to the 2022 Winter Olympics in February. More than 100 locally transmitted cases have been confirmed over the last week across 11 provincial areas, with most linked to 13 different tour groups.
