Pneumonia symptoms can vary from mild to severe, depending on the type of germ causing the infection, your age, and your overall health. Some of the common signs and symptoms of pneumonia include:

• Cough, which may produce phlegm or pus that is thick, blood-tinged, greenish, yellowish, or even bloody.
• Fever, sweating, and shaking chills.
• Shortness of breath, rapid, shallow breathing, and wheezing.
• Chest pain when you breathe or cough, which may be sharp or stabbing and gets worse when you breathe deeply or cough.
• Loss of appetite, low energy, and fatigue.
• Nausea and vomiting, especially in small children.
• Confusion or changes in mental awareness, especially in adults age 65 and older.
• Bluish color to lips and fingernails.

It is important to note that some of these symptoms can be similar to those of a cold or flu, but they last longer. Seek medical attention if you experience any of these symptoms, especially if you are at an increased risk of pneumonia.
