Positive enterovirus generalized nucleic acid is an abnormal laboratory result that suggests a possible viral infection. Need to combine with the patient’s symptoms to diagnose and treat: 1. If the patient has abdominal pain, diarrhea, nausea, vomiting and other symptoms at this time, it is generally identified as gastroenteritis caused by viral infection. To give anti-inflammatory, rehydration, anti-emetic and anti-vomiting treatment, where anti-inflammatory is generally given antiviral treatment, generally choose acyclovir or Chinese medicine. If the child has herpes on the hands, feet and mouth, it is generally considered to be hand, foot and mouth disease, which also requires antiviral treatment, in addition to other diseases that may be manifested. 2. If the patient has no obvious symptoms, it can be left untreated and continue to be observed, at this time the viral infection is mostly a self-limiting disease. Pay attention to rest, a reasonable diet, and after a period of adjustment, the test may turn negative.
