Pneumonia in Wuhan is caused by a new coronavirus, which is now spread mainly by droplets, and contact infection, which is now the main means of transmission of the new coronavirus. In addition, due to the virus in the environment for a long time after the formation of aerosols, into a cloth spread of the situation is still under observation, and can not be completely excluded. As for the feces because the presence of coronavirus can be detected, but fecal-oral transmission is not yet considered to be the transmission route of coronavirus, of course, do not rule out the possibility that if the excreta after drying, and then volatilized into the air to form aerosols, the possibility of this needs to be further observed in the future. Therefore, it is concluded that droplet and contact transmission are the main routes of transmission, and these two are easy to take measures to prevent at present. Source: Dr. Yurai
