Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing symptoms like 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 infants, elderly individuals, and those with weakened immune systems. Treatment typically involves antibiotics for bacterial pneumonia, while viral pneumonia may require supportive care.
