Although there are similarities between the new crown epidemic symptoms and the common cold, there are differences between the two in terms of symptoms and pathogens. 1. Symptom response: most of the symptoms of the common cold are relatively mild, such as: nasal congestion, sneezing, etc., but the new crown epidemic symptoms are usually more serious and complex than the common cold, for the sore throat has been described by some patients as a cutting pain, such as swallowing glass slag-like pain. In addition to nasal congestion, runny nose, some of the new crown patients may also have a reduced sense of smell and taste, myalgia, diarrhea, etc., and in severe cases, acute respiratory distress syndrome may also occur. 2. Pathogen: Common cold is caused by parainfluenza virus, adenovirus, respiratory syncytial virus and other infections, so the nucleic acid test result of new coronavirus is negative. On the other hand, new coronavirus is caused by new coronavirus, and the nucleic acid test result will be positive. For patients, no matter whether the symptoms are caused by common cold or epidemic symptoms, it is recommended to go to the hospital, complete the relevant examinations under the advice of the doctor to clarify the cause of the disease and receive treatment for the right cause.
