Video - Upper respiratory tract infection

An upper respiratory tract infection (URTI) is a viral or bacterial infection that affects the nasal passages, sinuses, pharynx, or larynx, typically causing symptoms such as congestion, runny nose, sore throat, cough, and fever. Common URTIs are tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. The transmission of URTI can occur through direct contact with an infected person or through exposure to airborne droplets from coughing or sneezing. Good hygiene practices and avoiding close contact with infected individuals can help prevent the spread of URTI.
