The increase was modest by global standards but significant for China, where outbreaks are quickly tackled when they surface.
Guangzhou, capital of Guangdong province, reported 2,377 new local cases for Nov. 7, up from 1,971 the previous day.
"The lockdown situation has continued to deteriorate quickly across the country over the past week, with our in-house China COVID lockdown index rising to 12.2% of China's total GDP from 9.5% last Monday," Nomura wrote in a note on Monday.
"We continue to believe that, while Beijing may fine-tune some of its COVID measures in coming weeks, those fine-tuning measures could be more than offset by local officials' tightening of the zero-COVID strategy."
In the southwest metropolis of Chongqing, the city reported 281 new local cases, more than doubling from 120 a day earlier.
