WUHAN, China — One week into a lockdown, anger and anxiety deepened in China on Thursday as the central province at the center of the coronavirus outbreak endured shortages of hospital beds, medical supplies and doctors.

In a sign of growing frustration, a relative of a patient infected with the virus beat up a doctor at a hospital in Wuhan, the capital of Hubei Province, the state broadcaster CCTV reported on Thursday, citing the police. The man was accused of pulling and damaging the doctor’s mask and protective clothing — potentially exposing him to the virus — after his father-in-law died in the hospital. The man was later detained.

At the same time, hospitals in the region renewed pleas to the public for help to replenish their supplies, which were fast disappearing. The shortages have become especially severe in Huanggang, a city of seven million not far from Wuhan, where some medical staff members were wearing raincoats and garbage bags as shoe covers to protect against infection, according to Yicai, a financial news site.
