What should I do if I have severe cough due to influenza B?

Gargling with saline water can help relieve throat discomfort. Using a humidifier in your living environment helps maintain moist air and alleviate throat irritation. In addition, avoid smoking and secondhand smoke, and minimize exposure to irritating substances in the air. If you experience other severe symptoms such as shortness of breath, chest pain, high fever, or if your cough persists for an extended period, seek medical attention immediately.
