Beijing, Aug 6: China recorded another 80 locally transmitted cases of COVID-19 on Friday, as the country seeks to control the biggest flare-up since the original 2019 outbreak with a combination of lockdowns, mass testing and travel restrictions.

Of the new cases, 58 were found in the eastern city of Yangzhou in Jiangsu province, where the highly contagious delta variant spread among airport workers in the provincial capital of Nanjing. Other cases were found in six provinces from tropical Hainan in the south to Inner Mongolia bordering on Russia.

That has taken the number of cases linked to the Nanjing outbreak to at least 1,222 since the middle of last month, prompting renewed travel restrictions, community lockdowns and the sealing off of a city of 1.5 million.

Such measures have been implemented with much success following local outbreaks under China's “zero tolerance” approach to the pandemic, although they are being seen as taking a major toll on society and the economy, stirring speculation that a new approach may be needed that allows for the virus to circulate to some manageable degree.
