You must wear N95 masks when taking public transportation in Dalian. Can N95 masks really guarantee that you will not be infected?

Dalian City issued a traffic adjustment notice. The city’s bus lines will deliver one bus every half hour and one bus every two hours during the morning and evening peak hours. Metro Line 12 will operate during the morning and evening peak hours. All passengers Passengers on buses, buses and subways are required to wear N95 and above masks. Those who fail to comply with epidemic prevention requirements and cause the spread of the epidemic must be held accountable. Faced with sudden new policies, citizens will inevitably complain. For those who only need to travel without N95 masks, this may delay the development of things and even bring life risks. According to common understanding, if universal silence cannot be implemented, the passenger capacity of buses should be increased rather than reduced to reduce crowd gatherings, meet people's needs for rapid transportation, and achieve scientific arrangements for seat spacing.

Due to the high risk of the spread of the epidemic, travelers have been arranged to gather frequently throughout the day and stay at bus stations and subway entrances and exits across the city for long periods of time. Requiring citizens to wear N95s seems like a "patch" to a policy that doesn't care about their heads and butts, so I'm afraid the policy makers and enforcers know that the risk is not unruly citizens but loopholes in the policy, only Convince yourself that the risks can only be offset if citizens are well protected. But this policy brings too many uncertainties. Wearing an N95 mask can only mean that you are less likely to be infected, but it does not necessarily mean that you will not be infected.
