Li Huiyong, who leads a team of 380 that treats garbage, said household waste would be transported to incineration plants, and medical waste would be properly disposed of.

Zhengzhou reported 41 new locally transmitted confirmed cases and 256 asymptomatic carriers of COVID-19 on Sunday. Li Huifang, deputy secretary-general of the municipal government, said at a news conference on Sunday that the recent outbreak has become the longest and had affected the most people since COVID-19 emerged.

The impact of multichain transmission has posed great challenges in city governance and services, so that sometimes the local government failed to transport patients in time, offer sufficient necessities, or take targeted prevention and control measures, which greatly affects people's work and life, she said.
