1. The new coronavirus belongs to the beta coronavirus of the genus β, and research has shown that it has more than 85% homology with bat SARS-like coronavirus (bat-SL-CoVZC45).
2. The virus is sensitive to UV and heat.
3. For 30 minutes at 56 ° C, ether solvents, 75% ethanol, chlorine-containing disinfectants, peracetic acid, and chloroform and other lipid solvents can effectively inactivate the virus.
4. Chlorhexidine cannot effectively inactivate the virus.
5. The sources of infection seen so far are mainly patients with new coronavirus infections.
6. Asymptomatic infection can also be a source of infection.
7. Asymptomatic infection is weaker. Li Xingwang, a member of the National Medical Experts Group: Asymptomatic infection may have a lower viral load and weaker transmission, and most often occur in contact with patients, especially family cluster infections.
8. Zhong Nanshan emphasized that the most effective prevention and control measures at present are early detection and early isolation.
9. WHO: The pneumonia outbreak of new coronavirus infection has not yet constituted a global epidemic.
10. Respiratory droplets and contact transmission are the main routes of transmission.
11. Transmission routes such as aerosols and the digestive tract remain to be determined.
12. The population is generally susceptible, and children are no exception.
13. The incubation period is 1-14 days, mostly 3-7 days.
14. Fever, fatigue, and dry cough are the main manifestations.
15. A few patients have symptoms such as nasal congestion, runny nose, sore throat and diarrhea.
16. In the course of severe and critically ill patients, there can be moderate to low fever, even without obvious fever.
17. Mild patients show only low fever, mild fatigue, and no pneumonia.
18. According to the current cases, most patients have a good prognosis, and a few patients are critically ill. The elderly and those with chronic underlying disease have a poor prognosis, and the symptoms in children are relatively mild.
19. Liu Qingquan, member of the expert group of the National Health Commission: The success rate of treatment is higher than that of influenza A and bird flu.
20. No effective antiviral treatment has been identified.
21. Avoid blind or inappropriate use of antimicrobials, especially in combination with broad-spectrum antimicrobials.
22. De-isolation and discharge standards: the body temperature returned to normal for more than 3 days, respiratory symptoms improved significantly, pulmonary imaging showed significant absorption of inflammation, and two consecutive consecutive tests for respiratory pathogenic nucleic acid were negative (sampling interval at least one day).
23. Qiu Haibo, a member of the expert group of the National Health Commission: From clinical experience, patients in the rehabilitation period are not infectious, and discharged patients are not infectious.
24. No virus mutations have been found so far.
25. World Health Organization: There is no evidence that pets, such as dogs and cats, are infected with the new coronavirus.
26. Healers are still at risk for reinfection. Zhan Qingyuan, leader of the pneumonia prevention expert group at the China-Japan Friendship Hospital: Generally speaking, humans will produce antibodies after virus infection, but some antibodies do not last for a long time. People who have recovered should still strengthen their protection.
27. The vast majority of patients with pneumonitis infected with the new coronavirus are mild.
28. It is not advisable for people who are not sick to take medicine.
29. Ordinary people can wear medical surgical masks for daily protection. It is not necessary to use N95 masks.
30. Jiang Rongmeng, a member of the expert group of the National Health and Health Commission: The virus settles quickly after coming out of the human body and generally does not float in the air.
