Influenza B complicated with pneumonia causing persistent high fever

Patients with influenza B complicated by pneumonia should receive strict antiviral treatment to suppress viral replication and prevent viral spread. In addition, low-dose antiviral and anti-inflammatory medications should be taken as recommended by physicians to alleviate symptoms and improve patient discomfort and clinical signs. Patients should also actively cooperate with medical examinations and promptly adjust treatment plans to effectively control the disease. They may take supplements such as antioxidants and probiotics to accelerate recovery. Furthermore, patients should maintain a nutritious diet, consume more fresh vegetables and fruits, and ensure adequate rest.
