Pertussis, this contagious disease, once diagnosed, requires isolation to prevent infection to healthy children or even adults with low immunity. It is necessary to provide an isolated room for the child, and attention should be paid to indoor ventilation, appropriate temperature, frequent cleaning and sunning of clothes and bedding, ensuring adequate and good sleep, and maintaining clean, ventilated air indoors. Dietary adjustments should also be made, avoiding too cold, spicy, or acidic foods. Timely selection of sensitive antibacterial drugs and cough suppressants can help alleviate symptoms of coughing and wheezing.
