PY - 2020 T2 - Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e AB - Acute bronchitis is a self-limited respiratory infection causing inflammation of the large airways characterized by cough without evidence of pneumonia. The common cold is a viral infection of the upper respiratory tract, primarily affecting the nasal mucosa causing congestion, rhinorrhea, and sneezing. Influenza, or the flu, is a respiratory illness with fever, myalgias, cough, and fatigue. The clinical syndromes associated with these conditions overlap, and their causative pathogens are often similar. Infections of the upper respiratory tract also cause specific clinical conditions such as otitis media (see Chapter 242, “Ear Disorders”), pharyngitis and epiglottitis (see Chapter 246, “Neck and Upper Airway”), bronchiolitis (see Chapter 116, “Neonatal Emergencies and Common Neonatal Problems”), tracheitis (see Chapter 126, “Stridor and Drooling in Infants and Children”), and sinusitis (see Chapter 244, “Nose and Sinuses”).
