Generally, respiratory syncytial virus can be cured in about 1 week, but it should be analyzed specifically according to the patient’s age, physical fitness, site of infection and severity of infection. 1. Respiratory syncytial virus is a common virus that causes respiratory tract infections and manifests itself differently in different patients. If the patient’s upper respiratory tract is infected, the symptoms are mild and only show a slight cough, the patient does not need medication, and the disease can be cured in a week or so. 2. If the patient’s resistance is poor, resulting in lower respiratory tract infection or even the formation of pneumonia, antiviral treatment is needed, such as ribavirin tablets, and the patient can be cured in five to seven days. In children, especially those under two years of age, poor resistance can also cause capillary bronchitis, and the treatment time is often more than 10 days. If infected with respiratory syncytial virus, hospitalization as soon as possible, active treatment under the guidance of the doctor, not blindly use drugs.
