Chapters 22-24

1. sudden, major genetic change from reassortment of two or more distinct viral strains.
5. Intrauterine infections that occur specifically during pregnancy when pathogens bypass maternal defenses to infect the developing fetus.
7. Reemerging pathogens demonstrating a clear resurgence
8. exfoliative toxins by Group II staphylococci. More common in infants due to immature renal clearance of the toxin. Widespread epidermal shearing and blistering.
9. Pathogens passed from mother to baby via the placenta during gestation, or through direct mucosal contact during late pregnancy and delivery.
10. The successful establishment, replication, and subsequent chain of transmission of that pathogen within the new host population.
11. Small, gradual genetic mutations (point mutations) that occur randomly over time as virus replicates
13. Any medical condition present at birth, regardless of its primary origin (genetic, structural, or infectious).
15. Children frequently acquire Herpes Simplex Virus type 1 (HSV-1) via direct contact with asymptomatic adults or individuals with active cold sores
16. Common name for Staphylococcal Conjunctivitis
17. High-incidence bracket for pathogens for young adults including Chlamydia, gonorrhea, herpes simplex virus, Human Papillomavirus (HPV), syphilis, Hepatitis B and C, and HIV

2. the progressive, age-associated decline in overall immune function
3. A highly superficial, contagious skin infection. The most common form is caused by Staphylococcus species, presenting with classic honey-colored crusts around the mouth and nose
4. Driven by orthomyxoviruses; dense living and social environments (dormitories, classrooms) place young adults at high risk for rapid epidemic spread
6. The initial entry of a novel pathogen into a new, susceptible host population.
12. Pathogens newly recognized or identified within the past two decades
13. Caused by Treponema pallidum (Spirochete)
14. Toxoplasma gondii(Protozoan)
