Once pneumonia is diagnosed, active antimicrobial treatment is necessary, and pneumonia can be cured. Additionally, for patients with low immunity or those who frequently suffer from respiratory diseases, annual influenza and pneumonia vaccinations can be administered for preventive measures.

symptoms of pneumonia in children

Pneumonia is a particularly common infectious disease of the respiratory system. Children, due to decreased disease resistance and low immunity, are especially susceptible to upper respiratory and lung infections. The main clinical symptoms of childhood pneumonia are fever and cough. Additionally, children may experience loss of appetite and vomiting. When these symptoms occur, it is advisable to take the child to the hospital for an examination. The doctor can perform auscultation and collect routine blood tests to preliminarily determine the presence of an infection. If pneumonia is suspected, further imaging studies are recommended for a definitive diagnosis.

Differential Diagnosis of Pediatric Pneumonia

Childhood pneumonia needs to be differentiated from other respiratory diseases such as bronchial foreign bodies, bronchial asthma, and pulmonary tuberculosis. A bronchial foreign body generally has a history of inhalation of foreign objects, sudden choking coughs, and a chest X-ray might indicate atelectasis or pulmonary emphysema. If the foreign body has been present for a long time, the disease course is prolonged and may lead to secondary infections, similar to pneumonia or concurrent with pneumonia. The differentiation of bronchial foreign body involves detailed medical history inquiries to check for inhaled foreign objects, then using symptoms and auxiliary examinations like chest X-rays for confirmation. Bronchial asthma, especially in children, might not always present with obvious wheezing attacks but rather persistent coughing. The X-ray might show increased and disordered lung markings and pulmonary emphysema, which can easily be confused with pneumonia. Typically, children with bronchial asthma have an allergic constitution and generally require pulmonary function tests and other auxiliary examinations to differentiate from pneumonia. Pulmonary tuberculosis generally occurs in those with a history of contact with tuberculosis patients. Their tuberculin skin test is positive, and X-rays may show features of tuberculosis lesions in the lungs, which can be used to differentiate from pneumonia.

What department should I go to for pneumonia?

Pneumonia, as the name suggests, is inflammation of the lungs and belongs to the category of respiratory diseases. Therefore, the primary department to consult is Respiratory Medicine. In places where there is no Respiratory Medicine department, such as community health service centers or township health clinics, patients would have to consult the general internal medicine department instead. Of course, if the symptoms of pneumonia are severe and the condition is critical, and it happens outside of regular outpatient hours, then the patient must be seen by the emergency medicine department. The emergency medicine department will manage and triage pneumonia patients, and then decide their next steps, such as whether to transfer them to the ICU, a regular Respiratory Medicine department, or keep them for observation in the emergency department.

How many shots are in the pneumonia vaccine?

Currently, there are two general types of vaccines for preventing pneumococcal pneumonia. One type is the 23-valent vaccine, suitable for high-risk populations over two years old. The other type includes the 7-valent or 13-valent vaccines, which are for preventing pneumococcal infections in infants under two years old. Infants under two usually follow a "three plus one" vaccination regimen, which involves three primary immunization doses with at least one month between each dose, followed by a booster shot. Additionally, adults over two years old or other high-risk groups are advised to take the 23-valent vaccine, which requires only a single dose. However, those who are frail or have poor immune responses may need a second booster dose five years after the initial vaccination.
