Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing symptoms such as cough, fever, chills, and difficulty breathing. It can be caused by various pathogens, including bacteria, viruses, and fungi. Pneumonia can range from mild to severe and is particularly dangerous for young children, the elderly, and those with weakened immune systems. Treatment typically includes antibiotics for bacterial pneumonia and supportive care for viral cases.
