It is not possible to determine whether influenza A is getting better on your own, and should be analyzed by a physician in conjunction with relevant tests.
Whether influenza A has improved or not cannot be judged by oneself, because it cannot be ruled out that some patients still have influenza A virus in their bodies even though their symptoms are gradually decreasing, so stopping medication without authorization will affect the control of influenza, and the condition will be easy to rebound. If you want to accurately determine whether the flu is getting better or not, you need to consult a doctor in a timely manner and conduct diagnosis and analysis through relevant examinations.
To analyze whether influenza A is getting better or not, we need to do routine blood tests, which can be identified according to the level of white blood cells and the platelet index; and then we need to do blood biochemistry tests, which are mainly based on the indexes of creatine kinase and aspartate aminotransferase. After that, it is also necessary to check serum viral nucleic acid and virus isolation, etc.; if necessary, some auxiliary examinations can be done, including chest radiographs, CT, etc..
Influenza A can first follow the above examination to determine whether the condition has improved or not, and if it is completely recovered and no viral presence is found, the medication can be stopped according to the doctor’s requirements.
