Weakly positive influenza A is weakly positive for influenza A virus and usually takes a week to return to normal. Timely treatment can shorten the recovery time, such as taking oral oseltamivir as prescribed by the doctor, but the recovery time varies due to the different constitution of individuals. Weakly positive influenza A refers to the influenza caused by influenza A virus, which manifests itself as chills, high fever and headache. The normal natural course of influenza is one week, but if antiviral drugs such as oseltamivir are used within 48 hours of the onset of the disease, the course of the disease can be shortened, and the body temperature will usually be reduced after 2-3 days, and recovery can be achieved in 3-5 days. However, the recovery time varies depending on the individual’s constitution. Weakly positive for influenza A does not mean that the symptoms are mild. Some patients with influenza A have negative nasopharyngeal swabs, but the results of retesting are positive, therefore, weakly positive does not mean that the disease is mild. In addition, patients with weakly positive A-flu should be isolated. If you have a weak positive case of influenza A, it is recommended that you seek immediate medical attention, complete the relevant examinations under the guidance of your doctor, and then follow the doctor’s instructions to take treatment.
