Document Summary
Supportive therapy: already colonized, can be infected. Supportive therapy: antibiotics if bacterial infection, adult cases most common. Streptococcus moves from pharynx to middle ear via auditory tubes. Streptococcus moves from pharynx to sinuses via throat. Routine practice precautions: children, immunocompromised, healthy individuals can still contract (highly contagious). Supportive therapy: transmission: via respiratory droplets, fomites, and direct contact; a single virus is sufficient to cause infection, hospital: hand-washing & routine practices. Pharynx appears red; presence of purulent abscesses and swollen lymph nodes. Pain during swallowing, bad breath, fever, headache, malaise. Severe ear pain due to inflammation & pressure on ear drum. Sinus pain & pressure, headache, general feeling of malaise: only bacterial infection if acute rhinosinusitis lasts. >10 days with high fever, pus filled nasal discharge. Remains infective for hours outside the body & is highly contagious; exits host cell though lysis.
