Close contact and droplet transmission are given in the fifth edition of the Pneumonia Protocol for Novel Coronavirus Infection as the very clear modes of transmission known so far. Whether aerosol and digestive tract could be the modes of transmission of novel coronaviruses remains to be further tested. The digestive tract, known as the fecal-oral route of transmission, has also been found to be positive for novel coronavirus nucleic acids in stool and anal swabs of patients. Novel coronavirus can be transmitted through close contact and droplet transmission, so it is important to avoid crowd contact, protect and self-isolate, open windows more often and wash hands regularly during daily prevention. If all can do a good job of self-isolation, after a longer isolation period, all patients may have passed the incubation period, and the virus can be slowly controlled. Or after the weather becomes warmer, the virus can be controlled because it is self-limiting. So be sure to protect yourself and stay away from the house as much as possible.
