What is Lower Respiratory Tract Infections?

Lower respiratory tract infections are viral or bacterial infections affecting the trachea, bronchi, and lung tissue. Acute bronchitis, pneumonia, and bronchiolitis are the main forms.

Although viral agents (influenza, RSV, rhinovirus) are the most common cause, bacterial agents (S. pneumoniae, H. influenzae) can also lead to serious infections. In immunocompromised individuals, atypical agents may come to the fore.

In healthy adults, most lower respiratory tract infections improve in 1-3 weeks. However, severe course requiring hospitalization can be seen in elderly, COPD, or diabetic patients.
