Cough and thick nasal discharge in the later stage of influenza B

Coughing and thick nasal discharge during the later stages of influenza B are common symptoms, primarily caused by respiratory inflammation. The most frequent cause is viral infection, though it may also result from certain allergic reactions. Additionally, chronic conditions such as bronchitis, asthma, and chronic obstructive pulmonary disease (COPD) could contribute to cough and thick nasal discharge in the later phase of influenza B. To treat cough and thick nasal discharge following influenza B, it is essential first to evaluate the patient's respiratory inflammatory symptoms to identify the underlying cause and implement appropriate treatment measures. Treatment options may include increasing fluid intake, improving indoor air circulation, and using oral, inhaled, or intramuscular medications. For patients with chronic conditions, antibiotics, lung function regulators, and medications to improve respiratory system function may be required. If conventional treatments are ineffective, some traditional Chinese medicine approaches, such as cupping or massage therapy (tuina), may be considered.
