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.

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.

What are the symptoms of pneumonia?

Pneumonia can have many manifestations, and each person's symptoms can be different. It is highly heterogeneous, varying from mild to severe and can last for short or long durations. The main factors depend on the type of pathogen involved and the state of the body. The most common symptoms of pneumonia are coughing and producing sputum. The cough can be mild or severe and may be accompanied by sputum. The amount of sputum can vary and may be yellow, green, red, or rust-colored. Other possible symptoms include chest pain, difficulty breathing, respiratory distress, and most cases of pneumonia also involve fever. The duration and severity of the fever are somewhat related to the course of the illness. However, a small portion of patients may have atypical symptoms, especially older adults, who may not show direct respiratory symptoms but instead exhibit consciousness disturbances such as coma, confusion, fatigue, and more.

What department does pneumonia go to?

What department should I go to for pneumonia? Pneumonia, as the name suggests, is a lung disease, which is to say it is a disease of our respiratory system. Therefore, the most appropriate department to visit would be the Department of Respiratory Medicine. If the patient's condition is relatively stable, they can visit the outpatient Respiratory Medicine department. Of course, there are a small number of patients whose condition is very critical, and in such cases, they must first visit the Department of Emergency Medicine. The doctors in Emergency Medicine will decide based on the patient's condition whether their next step should be to go to Respiratory Medicine, be admitted for in-hospital treatment, remain in the emergency for observation, or need to be admitted to the ICU for further emergency treatment.

Can pneumonia heal by itself?

Pneumonia is generally not self-healing; only a few pneumonia cases caused by specific pathogens, which lead to milder infections, can heal by themselves, such as pneumonia caused by Mycoplasma pneumoniae, which is self-limiting and can heal. However, most cases of pneumonia require standard treatment, such as pneumonia caused by Streptococcus pneumoniae and infections caused by Staphylococcus aureus. Therefore, if diagnosed with pneumonia, it is essential to seek immediate medical attention at a hospital. Relying on self-healing is unrealistic since self-healing cases are rare, and most pneumonia cases require standard treatment to recover.

How is pneumonia treated?

Pneumonia is a common disease in clinical practice, with patients often experiencing symptoms such as fever, cough, and expectoration. If a lung X-ray is taken, shadows can be seen in the lungs. The treatment of pneumonia primarily involves addressing the cause. For instance, if it is bacterial, appropriate sensitive antibiotics are chosen for treatment. If it is caused by a virus, suitable antiviral drugs are selected, and for fungal pneumonia, antifungal drugs should be chosen. If it is related to allergies, anti-allergy medications should be used. Additionally, symptomatic treatment is applied, such as antipyretics for fever. Depending on the situation, medications for cough suppression, phlegm reduction, and asthma relief may also be used. (The use of medications should be under the guidance of a doctor.)
