On Monday, China reported 143 new cases, up from 125 the day before.

According to authorities, the highly transmissible delta form is mostly responsible for China's recent clusters.

The National Health Commission said that 108 of the new confirmed illnesses, the largest number since Jan. 20, were locally transmitted, up from 94 the day before, while the rest were imported.

Most local infections were in the eastern province of Jiangsu and the central province of Henan.
