1, novel coronavirus concept
Coronavirus isolated from the lower respiratory tract of patients with unexplained pneumonia in Wuhan is a novel coronavirus named 2 0 19-nCOV. This virus is sensitive to ultraviolet light and high temperature. 56 oc 56 oc 56oC 30 minutes, ether, 75% ethanol, chlorine-containing disinfectant, peracetic acid, chloroform and other fat solvents can effectively inactivate the virus. ?
2. novel coronavirus is easily infected.
People are generally susceptible. Pneumonia infected in novel coronavirus can occur in people with low immune function and normal immune function, which is related to virus exposure. For people with poor immune function, such as the elderly, pregnant women, or people with abnormal liver and kidney function and chronic diseases, children who are sick with each other after infection also have diseases. ?
3. The route of transmission in novel coronavirus.
The main modes of transmission are droplet transmission and contact transmission. Droplet transmission: When the patient or pathogen carrier exhales, sneezes or coughs, the virus is discharged through the nose and mouth, and the susceptible person can be infected after inhalation. Droplets: It is generally believed that water-containing particles with a diameter of > 5 um can enter the surface of sensitive mucosa through a certain distance (generally 1 m). Contact transmission: direct or indirect contact with secretions, blood, body fluids or excreta carrying the virus and articles contaminated by the virus may lead to infection. ?
4. novel coronavirus will spread from person to person
Yes Judging from the onset sequence of some cluster cases, the characteristics of person-to-person transmission are very obvious, and there is a certain range of community transmission. ?
5. Close contacts
Refers to people who have lived or worked with confirmed or highly suspected cases within 14 days. Including colleagues in the office, colleagues and classmates in the same classroom and dormitory, passengers on the same plane, etc. Other forms of direct contact include accompanying virus-infected patients, taking taxis and taking elevators. ?
6. Preventive measures for close contacts
All personnel (including medical staff) who may have had contact with suspected infected patients should be observed for 14 days. The observation period starts from the last day of contact with patients. Once you have any symptoms, especially respiratory symptoms such as fever, cough, shortness of breath or diarrhea, seek medical attention immediately!
