Pneumonia is an inflammatory condition affecting the lungs, commonly caused by bacterial, viral, or fungal infections.
It involves the inflammation of air sacs, leading to the accumulation of fluid or pus. Symptoms include cough, difficulty breathing, fever, and chest pain. Pneumonia can vary in severity, from mild to life-threatening, particularly in vulnerable populations.
Diagnosis often involves imaging studies and laboratory tests. Treatment includes antibiotics for bacterial infections, antiviral medications for viruses, and supportive care. Vaccination and proper hygiene are crucial for preventing certain types of pneumonia.
