The respiratory system is complex.

The respiratory (breathing) system can be affected by many different kinds of disease.

Chronic cough

Although not life-threatening, chronic (long-lasting) cough affects people’s social lives and mental well-being.

RSV

Respiratory syncytial virus (RSV) is the most common virus that leads to bronchitis and pneumonia in children under age 1. It affects the very young and can also affect older adults.

There is a lot to consider when deciding whether to participate in a clinical trial. Any clinical trial includes risks, which the study doctor will review with you. Make sure you understand the risks before participating.
