Have you been coughing a lot recently? It’s easy to think it’s just because of the weather, but there’s a chance that it’s a sign of something more.
Respiratory diseases have long been a major health concern in the Philippines, with pneumonia ranking among the top five leading causes of death in recent years.
Whether at home, school, or work, pneumonia can strike anywhere. That’s why understanding their differences is crucial, as it can be the first step towards better respiratory health.
What causes bacterial and viral pneumonia, and who is at risk?
Bacterial Pneumonia
Most commonly caused by bacteria such as Streptococcus pneumoniae. It can affect anyone, but it’s more prevalent among those with weaker immune systems including those recovering from surgery, young children, older adults, and individuals with respiratory conditions, or non-communicable diseases like hypertension and diabetes.
Viral Pneumonia
Caused by viruses like influenza (common in adults), respiratory syncytial virus (common in children), and SARS-CoV-2 (COVID-19).

What are the symptoms?
Bacterial pneumonia can develop gradually or suddenly, with symptoms that may include:
- high fever (up to 105°C)
- Cough with green, yellow, or bloody mucus,
- Chest pain that worsens with deep breathing or coughing
- Rapid breathing
- Confusion, especially in older adults.
Meanwhile, viral pneumonia can develop over several days, with early symptoms often resembling the flu, including:
- Fever
- Dry cough
- Headache
- Muscle pain
- Fatigue
However, as the illness progresses, the cough may worsen,and may develop into shortness of breath.
Detecting and Preventing Bacterial and Viral Pneumonia
Pneumonia, regardless of its type, is both preventable and treatable with early detection and proper care. Diagnosis typically begins with a chest X-ray, a quick and effective first-line test for detecting lung infections.
If more detailed imaging is needed, a CT scan provides a clearer view to identify complications or evaluate severe cases.
Additionally, pneumococcal vaccines help protect high-risk individuals from bacterial pneumonia.
