Coughing will not necessarily result in isolation, but coughing will certainly result in being asked to wear a mask and cover your mouth and nose before coughing. If coughing up sputum, the secretions will also have to be wrapped in tissue paper before they can be thrown into the garbage. Patients who cough are not necessarily infected with novel coronaviruses. If they are in Wuhan, Hubei or other neighborhoods with onset of disease, patients should promptly go to the hospital for a chest CT examination and, if necessary, a novel coronavirus nucleic acid test. Suspected patients suspected of novel coronavirus need to further improve other tests.
