Pneumonia is a respiratory infection that can cause a range of symptoms, from mild to severe. The symptoms of pneumonia can vary depending on the type of germ causing the infection, your age, and your overall health. Some of the common symptoms of pneumonia include:

• Cough: A cough that may produce phlegm or mucus, which can be greenish, yellow, or even bloody.

• Fever: A high temperature, sweating, and shaking chills.

• Shortness of breath: Difficulty breathing or rapid, shallow breathing.

• Chest pain: Chest pain when you breathe or cough, or sharp or stabbing chest pain that gets worse when you breathe deeply or cough.

• Fatigue: Feeling very tired or having low energy.

• Loss of appetite: Not feeling hungry or having a decreased desire to eat.

• Nausea and vomiting: Feeling sick to your stomach or vomiting, especially in small children.

• Confusion: Changes in mental awareness, especially in older people.

It is important to note that newborns and infants may not show any sign of the infection, while others may vomit and have a fever and cough. They might seem sick, with no energy, or be restless. If you experience any of these symptoms, especially if you have a high fever, bloody or unusually colored mucus, chest pain, or shortness of breath, you should seek medical attention right away.
