What is pnuenomia?

Pneumonia is an infection that inflames the air sacs in one or both lungs, which can 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. The severity of pneumonia can range from mild to life-threatening, particularly in vulnerable populations such as the elderly or those with weakened immune systems. Treatment typically involves antibiotics for bacterial pneumonia, while viral pneumonia may require antiviral medications and supportive care.
