Residential communities around the market were put under lockdown, along with the area around a second market, where three cases were confirmed. In all, 90,000 people are affected in the two neighbourhoods in the city of 20 million.
China had relaxed most of its controls after the ruling Communist Party declared victory over the virus in March, but Beijing suspended yesterday's planned restart of some primary schools and reversed the relaxation of some social isolation measures.
Of the new cases reported by the Health Ministry today, eight were imported by returning Chinese travellers, four were reported in Hebei province next to the capital and another was detected in the southwestern province of Sichuan that has seen relatively few cases.
No new deaths were reported and 210 people remained in treatment while another 114 are being monitored in isolation for showing signs of Covid-19 or for testing positive for the virus but showing no symptoms. China has reported 4634 deaths from Covid-19 among 83,064 cases.
