New coronavirus pneumonia first appeared in Wuhan, but now no contact with Wuhan people may also get pneumonia, early in the new coronavirus infection pneumonia need to ask whether there are Wuhan residents contact history, whether they have been to the South China seafood market, etc., but with the continuous development of the epidemic, the later will ask whether the contact with Wuhan residents or with Hubei residents have had contact with. Later on flights moving cars such as enclosed spaces, coaches, etc. or have not been to a crowded place, during the Spring Festival to return to their hometowns have not had contact with the patient in the local area, in the late even if there is no contact with the people of Wuhan or Hubei, due to the spread of the epidemic, may also be infected with the new coronavirus pneumonia. Therefore, we must isolate ourselves properly and try not to go out, even if we have no contact with Wuhan people, we may still be infected. If you really have to go out, try to wear a good mask, you can use medical surgical masks or N95 masks, no contact with Wuhan people may also get the new coronavirus pneumonia, so we should do a good job of self-protection in this extraordinary period.
