A low respiratory infection is an infection in your airways and lungs. The reasons for this can be:
- Influenza, or flu
- Pneumonia
- Bronchitis
- Tuberculosis
Viruses typically cause fewer respiratory infections. They can also be caused by bacteria. Cough is the main symptom of a lower respiratory infection. You may feel breathlessness, wheezing and a tight feeling in your chest. Untreated lower respiratory infections can lead to respiratory failure and death.

Risk Factors and Prevention
Low respiratory infection risk factors include:
- The flu
- Frequent exposure to poor air quality or lung irritation
- Smoking
- A weak immune system
- Crowded childcare settings, which mainly affect infants
- Asthma
- HIV
One of the best preventive measures you can take against low respiratory infections is to take a flu pill every year. People at high risk of pneumonia may also receive a vaccine. To avoid the transmitted bacteria, wash your hands regularly with soap and water. Especially before touching your face and before eating. Stay at home and rest until you feel better if you have a respiratory infection, as the rest of the treatment improves.
