Across
- 2. Removing a disease worldwide by ending all transmission of infection through the complete extermination of the infectious agent
- 5. Refers to the occurrence of disease in a community or region in excess of normal expectancy
- 8. Ability of the host to withstand infection, and it may involve natural or acquired immunity.
- 10. Ability to produce a poisonous reaction
- 14. Ability to enter and multiply in the host
- 15. Ability to penetrate and spread throughout a tissue
- 18. Refers to the constant presence of a disease within a geographic area or a population
- 19. Remove a disease from a large geographic area such as a country or region of the world
- 20. __________immunization refers to immunization through the transfer of a specific antibody from an immunized individual to a nonimmunized individual or by administration of an antibody-containing preparation
- 23. __________immunity develops from previous natural exposure to an infectious agent
- 24. vehicle Refers to transportation of the infectious agent from an infected host to a susceptible host via food, water, milk, blood, serum, saliva, or plasma
- 25. Refers to an epidemic occurring worldwide and affecting large populations
- 27. immunity refers to the immunity of a group or community, based on resistance of a high proportion of individual members of a group to infection
- 28. Arthropods (ticks and mosquitoes) or other invertebrates (snails) that transmit the infectious agent by biting or depositing the infective material near the host
- 29. __________immunity refers to species-determined, innate resistance to an infectious agent
Down
- 1. __________period: interval during which an infectious agent may be transferred directly or indirectly from an infected person to another person
- 3. __________immunization refers to the immunization of an individual by administration of an antigen
- 4. Infection transmitted from a vertebrate animal to a human under natural conditions
- 6. __________period: time interval between invasion by an infectious agent and the first appearance of signs and symptoms of the disease
- 7. One of the possible outcomes of infection, and it may indicate a physiologic dysfunction or pathologic reaction
- 9. __________transmission: passing of the infection from parent to offspring via sperm, placenta, milk, or contact in the vaginal canal at birth
- 11. __________transmission person-to-person spread of infection through one or more of four routes
- 12. Refers to the entry, development, and multiplication of the infectious agent in the susceptible host
- 13. Ability to produce a specific clinical reaction after infection occurs
- 16. Gathers the “who, when, where, and what”; these elements are then used to answer “why.”
- 17. Ability to stimulate an immunologic response
- 21. Major categories of these include: bacteria, fungi, parasites, and viruses
- 22. Ability to produce a severe pathologic reaction
- 26. Measure of the potential ability of an infected host to transmit the infection to other hosts
