1. What is novel coronavirus? What is the source of infection?
Novel coronavirus (coronavirus pneumonia COVID-19-19), as a new acute respiratory infectious disease, has become a major public health event in the world. The source of infection is mainly novel coronavirus infected people, and it is contagious in the incubation period, which is 1- 14 days, mostly 3-7 days. It is highly contagious within 5 days after onset, and people are generally susceptible.
Second, what is the route of transmission in novel coronavirus?
Transmission through respiratory droplets and close contact is the main route of transmission. Contact with items contaminated by viruses can also lead to infection. In the case of long-term contact with high concentration aerosol in a relatively closed environment, it may spread through aerosol. Since novel coronavirus can be separated from feces and urine, attention should be paid to the environmental pollution caused by its contact transmission or aerosol transmission.
3. What does "asymptomatic infected person" mean? Is it contagious?
Novel coronavirus is positive for pathogens, and has no related clinical manifestations, such as fever, dry cough, fatigue, sore throat, hypoesthesia, diarrhea and other symptoms and signs that can be self-perceived or clinically recognized. CT images have no COVID-19 imaging features. Asymptomatic infection is not low in infectivity, and disease progress may still occur, which requires centralized isolation and observation.
