If you have a cold or the flu, symptoms can last from days to more than a week. But if your fever, cough and feelings of being run-down persist, you may have pneumonia. This lung infection inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Pneumonia can range in seriousness from mild to life-threatening. It is most serious for infants and young children, people over 65, and people with health problems or weakened immune systems. Learn more about the symptoms of pneumonia and when you need to seek medical care.
