Understanding Pneumonia

Pneumonia is a respiratory infection that affects the lungs. It occurs when the air sacs in the lungs fill with fluid or pus, leading to symptoms such as cough, difficulty breathing, and chest pain. Pneumonia can be caused by various factors, including bacteria, viruses, fungi, or exposure to certain chemicals.

Definition of pneumonia

Pneumonia is an infection that inflames the air sacs in one or both lungs, causing them to fill with fluid or pus. This can make it difficult to breathe and can lead to symptoms such as cough, fever, and chest pain. Pneumonia can be caused by a variety of microorganisms, including bacteria, viruses, fungi, or even certain chemicals.

Causes of pneumonia

Pneumonia can be caused by different types of microorganisms, including bacteria, viruses, fungi, and certain chemicals. Bacterial pneumonia is often caused by Streptococcus pneumoniae, while viral pneumonia is commonly associated with influenza viruses or respiratory syncytial virus (RSV). Fungal pneumonia is usually seen in individuals with weakened immune systems, such as those with HIV/AIDS or who have undergone organ transplants. Inhaling certain chemicals or irritants can also lead to pneumonia.

Symptoms of pneumonia

The symptoms of pneumonia can vary depending on the age of the individual and the cause of the infection. Common symptoms include cough (with or without phlegm), fever, chills, shortness of breath, chest pain, fatigue, and sometimes confusion in older adults. It is important to seek medical attention if you experience these symptoms, as pneumonia can be life-threatening if left untreated.
