What does it mean to be exposed to the air at the same time?

At the same time, people exposed to the air refer to people who come into contact with patients infected with novel coronavirus, wild animals, articles contaminated by viruses or the environment, and have not taken protective measures at the same time.

At present, health management is carried out for five groups of people: close contacts, sub-close contacts, potential close contacts, potential exposures and space workers. Among them, close contacts, sub-close contacts and potential close contacts are all subject to centralized isolation or home isolation control policies, and they are not allowed to go out for nucleic acid testing and sampling by themselves, and they need to be sampled by epidemic prevention and control personnel.

After receiving the SMS prompt, people who may be exposed and space personnel should take safety protection, do not take public transportation, and immediately go to the nearest nucleic acid detection point for nucleic acid detection. If there is no nucleic acid test within 24 hours after receiving the message, a code will be marked as a yellow code, and it will become a green code within 24 hours after the test result is negative. Please pay attention to the official account of "Xi 'an Publishing" WeChat to inquire about the distribution of 24-hour service nucleic acid detection points.

The general public should actively cooperate with epidemic prevention and control institutions and implement various prevention and control measures according to the contents of short messages. Specific prevention and control measures will be announced through the official media, so please pay attention in time. At present, there are sporadic cases in many provinces in China, which need the support, cooperation and participation of citizens and friends.
