With the spread of the new coronavirus, professional scholars have become more and more aware of it. Generally speaking, the stronger the spread of the virus, the weaker the fatality, because the virus also needs to rely on the host to survive. With the latest cases of human-to-human transmission, we can see how contagious the virus is, which also has a certain reference value for our preventive measures.
Case 1: I was infected with the same bus as the patient for 2 hours
Recently lived in Zhuhai A 26-year-old young man was diagnosed with a new coronavirus pneumonia last week. Experts from the Centers for Disease Control and Prevention conducted an investigation and followed the melons and found that he was on the same bus with the case Sun a week before the onset of the disease. The bus was from Guangzhou South Station to Zhuhai, with a 2-hour drive.
Case 2: The neighbors who went up and downstairs may be infected because they took the elevator together
A man from Inner Mongolia recently was diagnosed with the novel coronavirus, but he did not have a clear history of going out and had never been to the farmers' market. He was also puzzled why he was infected. Subsequent epidemiological investigations found that he and another person infected with the novel coronavirus were neighbors upstairs and downstairs, and were likely infected by the elevator.
Case 3: The salesperson in Tianjin Department Store infected colleagues and customers, and the colleague was infected with her husband
Tianjin Baodi 1 Department Store went to a city to purchase goods and was infected with the new coronavirus. Then he infected two colleagues who were selling clothing on the same floor. One of the colleagues in turn infected his husband. At the same time, a customer had been infected after buying clothes in the department store for 3 hours.
Case 4: Shenzhen deliveryman may be infected due to object contact
Shenzhen Municipal Disease Control and Prevention released 1 of the transmission cases, a delivery rider was diagnosed and was delivering food during the 14-day incubation period. According to epidemiological investigations and research, the delivery guy has not clearly defined his exposure history and contact history. As for the cause of infection, the most likely possibility is that they are unconsciously exposed to infection sources or virus-contaminated items, such as contact with infected people who order takeout.
In addition to the above infection cases, the Shandong Provincial Center for Disease Control and Prevention found that the door handle and mobile phone were present in the homes of confirmed cases.
Through the above 4 confirmed cases, we can see that the new coronavirus is indeed quite contagious, so we should not take it lightly during the prevention and control period. The specific measure is to try not to go out. If you have to go out, you need to reduce contact between people and objects, keep a certain distance between communication and wear a mask, wash your hands, wash your face and change your clothes carefully after you go home.
