Wearing masks at all times will help ensure low exposure to the flu and other viruses for an extended period of time. But by doing so too often, natural immunity can be affected, Zhong Nanshan, a prominent respiratory disease expert, said.

Zhang Wenhong, head of the Center for Infectious Diseases with the Shanghai-based Huashan Hospital of Fudan University, said recently that human beings have fully built up their immunity to COVID-19, and that China will soon emerge from this public health emergency.

He believes that as the country has entered into a stage of low prevalence of the novel coronavirus, wearing masks has now become an optional measure.

Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that weekly COVID-19 infections and deaths had fallen to record lows last month since the pandemic emerged in late 2019, suggesting that the pandemic is also drawing to an end.
