Pneumonia: What is It and What You Should Know
1/7/2025
Pneumonia is a serious lung infection that inflames the air sacs in one or both lungs. It can be caused by various organisms, including bacteria, viruses, and fungi. “Symptoms often include cough with phlegm or pus, fever, chills, and difficulty breathing,” mentioned Aaron Shaw, DO, board certified internal medicine physician at Lakeside Physicians. In severe cases, it can be life-threatening, especially for older adults and those with weakened immune systems.
Pneumonia can be caused by different pathogens. The most common bacterial cause is Streptococcus pneumoniae, while viruses like influenza and COVID-19 can also lead to pneumonia. Symptoms vary but often include:
- Cough with phlegm or pus
- Fever and chills
- Shortness of breath
- Chest pain when breathing or coughing
- Fatigue and weakness
Preventing pneumonia is crucial, especially for high-risk groups. Vaccinations are an effective way to reduce the risk of pneumonia. There are two main vaccines recommended for adults:
- Pneumococcal vaccine: Protects against Streptococcus pneumoniae, the most common cause of bacterial pneumonia.
- Influenza vaccine: Since the flu can lead to pneumonia, getting an annual flu shot is recommended.
Treatment depends on the cause of pneumonia. Bacterial pneumonia is treated with antibiotics, while viral pneumonia may resolve on its own with supportive care. It's important to see a doctor if symptoms persist or worsen.
Pneumonia is a serious infection that requires prompt attention and preventive measures. Vaccinations play a key role in reducing the risk, especially for vulnerable populations.
Staying informed and taking preventive steps can help protect against this potentially life-threatening illness.
