Influenza A is influenza A. It doesn’t mean that patients with influenza A are fine as long as their fever goes down, it just means that they don’t need to take fever-reducing medication for symptomatic treatment after their fever goes down. Influenza A is an acute respiratory infectious disease caused by influenza A virus infection, which can lead to acute high fever, generalized muscle pain, fatigue and respiratory symptoms. Fever reduction only means that the condition has improved, not that it has been cured. Especially if other symptoms have not completely disappeared, the virus may still be present in the body, and it is still necessary to continue antiviral treatment, and also need to pay attention to rest. If the clinical symptoms disappear completely and the test results return to normal, recovery may be complete. Individuals suffering from influenza A should use medication in a scientific and rational manner under the guidance of a physician to promote recovery.
