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.

Symptoms of pneumonia cough in children

Pneumonia in infants commonly occurs in young children, especially those under two years of age. The onset of the disease is usually rapid, starting with symptoms of upper respiratory tract infections that gradually evolve into more pronounced respiratory symptoms. The cough is frequent, initially a dry, irritating cough, that progressively worsens as the disease advances. In cases of severe pneumonia, the cough may actually lessen. During the recovery phase, the cough gradually diminishes and rattling sounds can be heard in the throat due to mucus. After the mucus is cleared, there may still be occasional bouts of irritating dry cough, which will slowly subside.

Is bronchopneumonia the same as pneumonia?

Some patients might ask if bronchopneumonia is a type of pneumonia. Undoubtedly, bronchopneumonia is a type of pneumonia, categorized anatomically. It can be classified into lobar pneumonia, bronchopneumonia, and interstitial pneumonia. During X-ray imaging, bronchopneumonia typically shows as irregular patchy shadows distributed along the lung markings, with soft and blurry edges, without signs of consolidation. It often occurs in the lower lobes of both lungs. The treatment principles for bronchopneumonia are similar to those for common pneumonia, mainly involving the use of antibiotics, cough suppressants and expectorants, fever reduction, and other symptomatic treatments.

The difference between interstitial pneumonia and pneumonia

Interstitial pneumonia, also known as diffuse pulmonary interstitial fibrosis, mainly refers to a disease characterized by the replacement of the lung interstitium with some invisible fibrous tissues, leading to lung atrophy and difficulty breathing as the main manifestations. The pathological site of pneumonia is mainly in the alveoli and lung parenchyma, and patients mainly show symptoms such as coughing, expectoration, and fever, generally not experiencing difficulty breathing. Additionally, interstitial pneumonia and pneumonia have typical and distinct changes in imaging. Through imaging, it is basically possible to differentiate almost completely between interstitial pneumonia and pneumonia without the need for any special techniques.

How is pneumonia treated?

Pneumonia is a respiratory tract infectious disease that requires the timely selection of antimicrobial drugs and anti-inflammatory treatment, as well as the choice of symptomatic treatment medications. Symptoms of pneumonia include fever, headache, nausea, sore throat, cough, expectoration, chest pain, and difficulty breathing. The pathogens causing the infection vary, and so do the antibiotics used to treat them. For common bacterial infections, penicillin antibiotics or cephalosporin antimicrobial drugs can be selected. During an acute fever phase, antipyretic analgesics may be chosen or physical cooling methods may be employed.

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.
