Babies with HFMD usually do not have a cough, but usually have a cough considered to be caused by a respiratory infection. In this case, it is recommended to go to the hospital and let the doctor listen to see if there is bronchitis or bronchopneumonia, and take a chest X-ray if necessary to clarify the degree of infection. If the infection is mild, it can be treated with symptomatic support, such as oral cough suppressants. If the infection is severe, it may need to be treated with oral antibiotics or intravenous antibiotics to reduce inflammation, along with nebulized inhalation therapy. Pay attention to a light diet, avoid spicy and stimulating foods, and keep warm to avoid getting cold. Avoid going to places where people gather to prevent cross infection.
