The main respiratory diseases are flu, rhinitis, sinusitis, COVID-19, bronchitis, COPD, tuberculosis and asthma, for example.

Some people may be born with a chronic respiratory disease, which in addition to external causes, may be genetic, such as asthma. While acute respiratory diseases most often arise from infections of the respiratory system.
