Three cases of nucleic acid positive were found in Ningbo. How did they get infected?

The infection process of this family in Ningbo has not been made public officially, but it is certain that one of the three infected people is the source of infection for the other two. As for how the first person was infected, we can't know until the traceability investigation of Ningbo official institutions is over.

The general story is as follows: zhenhai district Theron Medical Group found a highly suspected positive sample in routine nucleic acid detection, and adopted a mixed sampling mode of 1: 10, which means that at least one person in 10 is suspected to be positive. This group reported to the superior health prevention and control department at about 6:30 pm on February 5, 20021year. After receiving the report, the epidemic prevention and control institutions in Ningbo and zhenhai district acted quickly, immediately took isolation measures for this 10 sampling object, re-examined the single-tube sample, and passed through the area at 20: 30 in the evening. At the same time, the municipal and district epidemic prevention and control departments organized personnel to carry out epidemic verification and epidemiological investigation.

At the same time, the medical staff also conducted emergency sampling tests on four family members living together. Finally, the initial screening positive infected persons and their two family members were confirmed to be infected. The other two infected people are their mothers and wives. The infected people have two children, but fortunately they are not infected. At present, it is determined that the infected family of three is infected with each other because of close contact. The first infected person may be infected by going out to contact with foreign virus carriers, or it may be caused by short-term contact with infected people after foreign virus carriers enter Ningbo. Infection caused by the situation? In short, no matter what kind of situation leads to infection, we should not take it lightly. Under the background of importing foreign defense and rebounding internal defense, Chinese people want Qi Xin to work together to safeguard our country's outstanding achievements in fighting the epidemic and ensure the harmony and stability of people's lives.
