On Feb. 2, the National Health and Wellness Commission held a press conference to introduce information about health protection in public places, transportation and different risk groups in the prevention and control of pneumonia outbreak with novel coronavirus infection. Feng Luzhao, a researcher at the Infectious Diseases Division of the CDC, said that recently, novel coronavirus was detected in the feces of confirmed patients in Wuhan, Shenzhen and even in the first case in the United States, a phenomenon that shows that the virus can replicate and exist in the digestive tract. However, whether the virus is transmitted through the fecal-oral route or through aerosols formed by droplets containing the virus requires epidemiological investigation and research to further confirm this phenomenon. Of course, at present, the main route of novel coronavirus infection is still based on proximity droplet transmission and indirect contact transmission. However, the phenomenon mentioned above also suggests the importance of washing hands regularly, especially when in contact with easily contaminated surfaces, and washing hands regularly before and after meals is a very important means of protection against this virus.
