On the evening of January 8, Tianjin held a press conference on the prevention and control of the new crown pneumonia epidemic.
After screening of key groups, as of 21:00 on the same day, 18 new cases of new coronavirus infection were detected among close contacts in Tianjin, and all of them have been transferred to designated hospitals for isolation and treatment.
According to Zhang Ying, deputy director of the Tianjin Center for Disease Control and Prevention, from the perspective of the relationship between cases and the chain of transmission, the 18 cases have been transmitted for at least three generations. Although this epidemic was discovered in the early hours of this morning, it may be in the community. It has been spreading for some time.
Therefore, for the trend of this epidemic, it is not ruled out that there may be other positive infected persons outside the closed control area, control area and prevention area.
With the nucleic acid screening of all personnel in the three districts this afternoon, there is still the possibility of finding more positive infections.
