Why is the disease concentrated in these three days?

　　From the 8th to the 10th, the prevention and control control was in place, forming a peak and a plateau period

　　Found cases are consumption of previously exposed cases

　　News from this newspaper (Reporter Xu Yang) Yesterday, at the 166th press conference on the prevention and control of the novel coronavirus pneumonia in Tianjin, Zhang Ying, deputy director of the Municipal Center for Disease Control and Prevention, introduced that the infection cases discovered in the early stage of our city can pass the The transmission chain is linked together, but the more than a dozen cases of infection recently discovered can no longer be linked through the transmission chain.

This shows that due to the rapid implementation of strict control in our city, some cases that have been infected with the virus but have not yet developed and spread have been screened out.

Even so, there is still a risk of community transmission of the epidemic. Therefore, our city will start the second round of nucleic acid screening for all employees.

　　Zhang Ying introduced that yesterday was the fifth day after the outbreak of the current round of the epidemic in our city. Judging from the overall incidence curve of the current epidemic, the three days of January 8, 9, and 10 had the highest incidence, forming a plateau period.

It is rare for such a respiratory infectious disease to have a peak at the early stage of discovery and a plateau at the same time.

This shows that the relevant screening and control measures taken by our city are very early and very fast. As long as all prevention and control measures are in place, the subsequent development of the epidemic can be controlled.

　　Why are the onset times on January 8th, 9th, and 10th?

Zhang Ying explained that after preliminary analysis and epidemiological investigation, it was found that this round of epidemics had spread in the community during the New Year's Day holiday.

It is understood that several childcare classes involved in the epidemic did not rest during the New Year's Day holiday. The children who participated in the childcare classes were exposed to the virus. After the start of school on January 4, the virus was passed on to other students in their respective schools, and these students brought the virus back. individual families, spread to different communities.

　　Because of this, after the case was discovered on January 8, many infected people who had begun to be infected and showed symptoms were found through rapid screening.

The cases discovered in these three days are the consumption of the early exposure cases. Due to the early detection and fast control, although the epidemic will spread in the community later, it will not cause large-scale and large-scale infection.

　　Zhang Ying said that because there is still a risk of the spread of the epidemic, it is hoped that citizens will take the initiative to cooperate with the nucleic acid screening of all staff in the city. In which area and when to do the test, they must obey the arrangement to avoid unnecessary gatherings.

At the same time, don’t skip screening or even avoid screening for some personal reasons.

If a citizen is unable to go to the sampling site due to inconvenience of mobility, they can report to the community, and the community will send people to sample or set up temporary sampling sites to facilitate screening for people who are far away from the sampling site or who have limited mobility.

　　Our city has announced the key risk places determined by research and judgment, and these are places that positive infected people have visited.

If citizens find that they have been to these key risk sites and find that they are in line with the trajectory of the infected person, they must report to the community as soon as possible, so that the CDC and relevant departments can investigate in time, and do not let themselves, family and friends at risk of infection.
