Pneumonia is a particularly common infectious disease of the respiratory system. In infants and young children with pneumonia, the main clinical symptoms include fever, crying, vomiting, and so forth. Since infants cannot express their discomfort, it is difficult to make a diagnosis. However, when a patient presents with fever, we first need to consider the possibility of a lung infection. We can determine whether there is an infection of the lungs through listening to the chest, routine blood tests, imaging examinations, etc., and then treat the pneumonia with effective anti-inflammatory therapy.
