Children with a cough should pay attention to the fact that it is usually caused by respiratory diseases such as acute tonsillitis, pharyngitis, upper respiratory tract infection, pneumonia and other diseases, so they need to go to the hospital for treatment in a timely manner. When you go to the hospital, you can directly register for pediatrics, pediatric respiratory medicine or immunology. A child’s cough is usually caused by a cold or fever, so you can first register for general pediatrics when you go to the hospital, because as a pediatrician, you should always see a cold or fever. However, if the condition does not improve after treatment in general pediatrics but gets worse, you need to transfer to another department and re-evaluate the cause. If it is caused by a respiratory tract infection, you can register pediatric respiratory medicine. If the cough is caused by an allergy, you can go to the immunology or allergology department to identify the specific allergen and provide symptomatic treatment. Some specialized hospitals have more detailed subspecialties, so if you are really confused, you can also consult the hospital’s receptionist, who will assign the appropriate department according to the child’s cough symptoms. At this stage, with the development of the Internet, it is also possible to make an appointment directly online, and it is generally recommended to register for general pediatrics first.
