There are 1 case of COVID-19 pneumonia in Heilongjiang province. Where is the source of this epidemic?

There is a new confirmed positive case in COVID-19, Heilongjiang Province. Where did the epidemic come from? In fact, only the positive patients in Heilongjiang were asymptomatic infected people imported from abroad, and the local government sealed and controlled them immediately after discovering the epidemic, and proved that the patients had cooperated closely. Moreover, the Heilongjiang government appeals to everyone to report to the local community immediately and implement prevention and control if there is an intersection with this positive patient's activity track, or if there is a history of traveling in an epidemic area in a high-risk area in China within 7 days. If there are symptoms such as dry cough, fatigue, fever, diarrhea, etc., don't take medicine by yourself, but go at the first time.

Although only one positive patient has been found in the local area for the time being, they still attach great importance to it, because one pill is likely to become more than a dozen cases or even more, so everyone should pay attention to this virus, because its infection rate is very high, and it is very likely that this person's virus has been hidden for some time, so during this time, he may go to various public places and many people will be infected by him, so if you have uncomfortable symptoms, you should immediately.

COVID-19 has been with us for several years, so there is no need to be afraid. Maybe when we first came into contact with this virus, we thought it was strange and didn't know its infectivity and virulence. Now that everyone is familiar with it, there is no need to panic. As long as we actively cooperate with the work of the community and medical staff, I believe that the society will be cleared up soon and everyone can live and work normally. Of course, you must remember to go to public places during this time.
