Nebulized inhalation for localized treatment of pertussis can be quite effective. It helps alleviate bronchial smooth muscle spasms and is used for spasmodic coughs, effectively easing cough symptoms as a symptomatic treatment measure. However, it is also necessary to target the infectious pathogens with oral or intravenous macrolide antibiotics for anti-inflammatory treatment. Drinking plenty of water, maintaining suitable indoor temperature and humidity, and having confidence in overcoming the disease are important. Although the course of the disease may be long, complete recovery is possible through proper treatment, so there is no need for excessive worry.
