E N D
Role of the Immune System • Collection of disease fighting cells that neutralizes foreign substances • Illness results when immune system does not neutralize foreign substances (antigens) • Cell-mediated response, humoral immune response (B-cells that produce antibodies), or nonspecific immune response (inflammation) • Auto-immune response against the body leads to damage of body’s own tissues
Viral Infections • Rhinovirus (Common Cold) • Etiology • Over 100 different rhinoviruses • Transmitted by either direct or indirect contact (cough, sneeze, speaking, touching contaminated article)
Sign and Symptoms • Begins w/ scratchy, sore throat, stopped-up nose, watery discharge and sneezing • Second batch may produce thick yellow nasal discharge, watering eyes, mild fever, sore throat, headache, malaise, myalgia, dry cough • Secondary - laryngitis, tracheitis, acute bronchitis, sinusitis, and otitis media • Management • Symptomatic treatment (may last 5-10 days) • Non-prescription cold medications • Eat a balanced diet, consume 64 oz. of water • Avoid emotional stress and extreme fatigue
