what is upper respiatory infection?
Question:
Answers:
Upper respiratory infections are common infections and include pharyngitis, sinusitis, epiglottitis, laryngotracheitis, and the common cold. Viruses play a significant role in the pathogenesis of many of these infections. Bacteria and other organisms also are responsible.
Pharyngitis is an inflammatory process of the pharynx, hypopharynx, uvula, and tonsils that can be caused by viral or bacterial infection and, occasionally, both. Distinguishing between these infections is important because rheumatic fever and acute glomerulonephritis may complicate untreated group A beta-hemolytic streptococcal infections (GAS), but they usually can be prevented by appropriate antibiotic treatment.
Sinusitis is an inflammatory process involving the paranasal sinuses (maxillary, frontal, ethmoid, and sphenoid). It usually is a bacterial complication of a viral upper respiratory infection.
Epiglottitis is a life-threatening disease observed most frequently in children aged 1-6 years, often during the fall and winter. Although less common, it also can affect adults.
Laryngotracheitis usually is the result of viral infection. The subglottic area and trachea are involved, whereas the area above the true vocal cords is spared. When children younger than 5 years have the infection, it is called croup.
The common cold is a mild, self-limited, catarrhal syndrome caused, for the most part, by members of 5 families of viruses. A small proportion of colds are complicated by bacterial infections of the paranasal sinuses and the middle ear, which require antimicrobial therapy.
