The Chinese mainland has seen a rise in newly confirmed COVID-19 infections for the fifth consecutive day, with the number jumping to three digits on Tuesday to 101, involving Beijing, Northeast China's Liaoning Province and Northwest China's Xinjiang Uygur Autonomous Region.

Tuesday was the first time that daily new cases exceeded 100 since March 6. The increasing number of infections has sparked public concerns that a resurgence of the outbreak is on its way.

Of the 101 cases, 89 were reported in Xinjiang, eight in Liaoning and one in Beijing which was linked to the outbreak in Liaoning, according to the National Health Commission on Wednesday.

Beijing has so far reported a total of two patients connected to the epidemic in Liaoning. Since July 22, the Liaoning epidemic has spread to at least nine cities such as Beijing and South China's Fujian Province. 

All 89 cases reported in Xinjiang are from capital city Urumqi, which also reported 15 silent virus carriers on Tuesday.  As of Wednesday, Urumqi has reported 320 confirmed COVID-19 patients and 133 asymptomatic infections. A total of 9,121 are under medical observation.
