Pneumonia is a lung infection that can be caused by bacteria, viruses, or fungi. It can be a serious condition, especially for young children, the elderly, and those with weakened immune systems. 

Symptoms of pneumonia may include coughing, fever, chest pain, shortness of breath, fatigue, and confusion. It is important to seek medical attention if you experience any of these symptoms. 

There are several types of pneumonia, including community-acquired pneumonia, hospital-acquired pneumonia, and aspiration pneumonia. Each type has different causes and risk factors. 

Treatment for pneumonia may include antibiotics, antiviral medications, or antifungal medications depending on the underlying cause. It is important to follow your doctor’s instructions and complete the full course of treatment.
