Chapter 37: Infectious and Communicable Diseases

The chapter then systematically addresses viral exanthems including measles with its characteristic three Cs presentation and Koplik spots, roseola infantum featuring fever followed by rash, rubella with its mild clinical course and teratogenic potential, mumps with parotid involvement and associated complications like orchitis and aseptic meningitis, and varicella presenting with progressive vesicular eruptions requiring strict isolation measures. Bacterial communicable diseases are covered including pertussis with its distinctive paroxysmal cough phase and respiratory management needs, diphtheria characterized by pseudomembrane formation and airway compromise risk, and poliomyelitis transmitted through fecal-oral routes with potential for ascending paralysis. Additional conditions discussed include scarlet fever with strawberry tongue and pastia lines, erythema infectiosum presenting with slapped cheek appearance, infectious mononucleosis with splenic rupture considerations, Rocky Mountain spotted fever transmitted by tick vectors, and methicillin-resistant staphylococcus aureus infections requiring contact precautions. The chapter emphasizes vaccination schedules, administration techniques, site selection, documentation requirements, contraindication assessment, and adverse reaction management including anaphylaxis protocols. Infection control principles encompassing airborne, droplet, and contact precautions are integrated throughout, with nursing roles including immunization history acquisition, patient and family education, outbreak prevention, and evidence-based care delivery across various care settings.
