What is Pneumonia?

Pneumonia is an infection of the lungs caused by bacteria, viruses, or fungi. It can cause inflammation, fever, and difficulty breathing. Depending on the type, pneumonia can range from mild to life-threatening.

Symptoms of Pneumonia

The most common symptoms of pneumonia are cough with sputum production, chest pain, fever, and difficulty breathing. Additional symptoms may include fatigue, nausea, vomiting, and muscle aches.

Types of Pneumonia

There are several different types of pneumonia, including:
• Bacterial pneumonia – caused by bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Legionella pneumophila
• Viral pneumonia – caused by viruses, including influenza and respiratory syncytial virus
• Fungal pneumonia – caused by fungi, including Aspergillus and Pneumocystis jirovecii
• Aspiration pneumonia – caused by inhaling foreign material, such as food particles, stomach acid, and saliva

Diagnosis of Pneumonia

To diagnose pneumonia, your doctor will take a medical history and conduct a physical exam. They may also order tests, such as a chest X-ray, blood tests, and a sputum culture.

Treatment of Pneumonia

The treatment of pneumonia depends on the type and severity of the infection. Mild cases may be treated with rest, over-the-counter medications, and increased fluid intake. More severe cases may require antibiotics, antiviral medications, or hospitalization.

Complications of Pneumonia

In some cases, pneumonia can lead to serious complications, such as:
• Respiratory failure
• Sepsis
• Pleural effusion
• Lung abscess

Prevention of Pneumonia

Pneumonia can be prevented by getting vaccinated, washing your hands regularly, avoiding contact with people who are sick, and avoiding smoking or exposure to secondhand smoke.
