Pertussis, once diagnosed, should be treated promptly with anti-inflammatory treatment and symptomatic care. Regarding diet, common fruits such as apples, bananas, grapes, pears, watermelons, pineapples, avocados, and mangoes can generally be consumed without special restrictions. Eating more pears, tangerines, and oranges can effectively moisturize the lungs, dissolve phlegm, suppress coughs, and alleviate symptoms. It is also important to drink plenty of water and maintain suitable indoor temperature and humidity to aid in recovery from the disease. Early detection and treatment of the disease, and the formulation of individualized treatment measures, are crucial.
