Upper Respiratory Tract Infections
Upper respiratory tract infections (URTIs) involve conditions affecting the nose, sinuses, pharynx, and larynx, with common types including influenza, the common cold, and sinusitis. Influenza is a contagious respiratory illness caused by various influenza viruses, leading to symptoms like fever and cough, while the common cold is primarily caused by rhinoviruses, resulting in similar symptoms. Diagnosis and treatment strategies vary among URTIs, with specific tests available for conditions such as sinusitis, pharyngitis, and otitis media.
