Cold does not affect the nucleic acid test result of novel coronavirus. The cold we usually talk about generally refers to upper respiratory tract infections, common clinical symptoms include fever, nasal congestion, runny nose and other discomforts, and the main pathogens are viruses, common rhinoviruses, influenza viruses, adenoviruses, parainfluenza viruses, and other kinds of viruses. Different viruses have different nucleic acids, and the nucleic acid test is for the specific nucleic acid of a certain virus, so the cold does not affect the nucleic acid test results of other viruses, such as the new coronavirus. At present, the main symptoms of new coronavirus infected people are fever, cough and other discomforts, and it is not easy to distinguish them from colds from the clinical symptoms alone. Nucleic acid testing can be a good way to identify whether a novel coronavirus infection is a cold caused by another virus. Patients with respiratory symptoms such as fever and runny nose must complete the nucleic acid test in time to prevent the spread of the epidemic due to underdiagnosis. If the symptoms are caused by a cold, it will not affect the results of the nucleic acid test for novel coronavirus.
