1. What is new corona pneumonia?
The new coronavirus is a new coronavirus of the genus β. Studies have shown that it has more than 85% homology with SARS-like coronaviruses in bats.
2. Virus sensitive points
Viruses are sensitive to heat and ultraviolet light
3. Virus killer
Fatty solvents such as ether, 75% ethanol, chlorine-containing disinfectants, peracetic acid, and chloroform can effectively inactivate viruses at 30 minutes at 56 ° C.
Chlorhexidine does not effectively inactivate viruses
5. Source of infection
The main source of infection seen by patients is mainly those infected with new coronavirus.
People with asymptomatic infection may also become the source of infection
7. People with asymptomatic infection
People with asymptomatic infections have weaker transmission capacity, and Li Xingwang, a member of the National Medical Expert Group: Asymptomatic infections may have less viral load and weaker transmission capacity, which often occurs with more contact with patients, especially Family aggregation infection is more obvious.
8. Prevention and control measures
Zhong Nanshan emphasized that the most effective means of prevention and control is early detection and early isolation.
WHO: The pneumonia outbreak of new coronavirus infection has not yet constituted a global epidemic.
10. Transmission channels
Droplets and contact transmission through the respiratory tract are the main transmission routes.
11. Not clear
The transmission routes of aerosol and digestive tract are yet to be clarified.
12. Infected people
The crowd is generally susceptible, and children are no exception.
13. Incubation period
The incubation period is 1-14 days, mostly 3-7 days.
