Wuhan: Citizens must wear masks in indoor public places and outdoor crowd gathering occasions

On March 25, thanks to the efforts of all citizens, Wuhan newly confirmed and suspected cases were reset to zero. However, at present, it is necessary to prevent sporadic cases from occurring and to strictly prevent foreign imports from outside. The epidemic prevention and control must not be relaxed.

On March 25, 117 bus lines in Wuhan resumed operation. From March 28, rail transit lines 1, 2, 3, 4, 4, and 7 will resume operation. In order to minimize the risk of infection for the crowd, citizens should wear masks throughout the public transport, maintaining spacing and hand hygiene.

Liang Jiansheng, director of the Center for Disinfection and Vector Biological Control of Wuhan Centers for Disease Control and Prevention, stated that according to the "Guidelines for Wearing Scientific Masks for the Public" issued on March 17 by the State Council's Joint Control and Prevention Mechanism for New Coronavirus Pneumonia The Government's Circular on Implementing Relevant Measures for Wearing Masks in Public Places (hereinafter referred to as the "Notice"), except for homes and open outdoor environments, citizens must wear masks in other places.

What responsibilities and risks should citizens bear if they do not wear masks in public places?

Liang Jiansheng said that according to the Circular, citizens must wear face masks in indoor public places and outdoor crowds. Those who do not wear masks to enter public places and do not listen to dissuasion shall be dealt with by the relevant competent authorities in accordance with their respective duties and laws. This notice will be implemented from January 22, and the termination date will be announced separately by the Municipal People's Government. In other words, this announcement is still in effect and has not been lifted.

Because asymptomatic infections and mild cases have a certain "hidden nature", which brings difficulties to early detection, experts recommend that citizens should continue to wear masks in accordance with the principle of responsibility to themselves and others.
