1, the symptoms are not obvious. 1 person causes 8 1 person to be infected. This case has a great impact, causing many people to be infected with the virus and many people to be taken away for isolation. The characteristic of this super communicator is that the clinical symptoms are not obvious, he has no discomfort, and many previous nucleic acid tests are negative. There were no symptoms of fever and cough in the early stage, and there was no abnormality in CT examination.
2. Strong spread, short distance: 1 person infected with 8 1 person, which led to the multiplication of isolated students in the university town, which fully explained the characteristics of rapid and strong spread of this epidemic. The Zhuanghe epidemic in Dalian is an aggregated and collective epidemic. In a short time 100, more than 300 cases in a few days. It is really worrying that the source of the epidemic has not been found so far. The spread distance of this epidemic is too short to prevent, and it also reminds us to do more detailed epidemic prevention work in the future.
3. Strong infectivity This super-communicator is characterized by strong infectivity, with 1 person infecting 8 1 person, resulting in an outbreak of cluster epidemic in schools and a sharp increase in the number of cases. It shows that the epidemic situation is far from being well controlled as we thought. It is necessary to strengthen prevention and control, and at the same time do a good job in disinfection and disinfection of epidemic-related places. The most important thing is to isolate the relevant personnel and increase the isolation time as much as possible.
4. The long-hidden epidemic shocked the super communicators. It spread to 8 1 time and nucleic acid detection 16 times, which is enough to show that the virus has a long hiding period. I believe everyone has seen the characteristics of this epidemic, which is particularly stubborn and likes to lurk. Therefore, it is necessary to do personal prevention and control, wear a mask, and disinfect every day. It is necessary to be prepared for a protracted war, and vaccination for the whole people can not only ensure their own safety, but also protect the safety of their families and others.
