Across
- 1. Similar to epidemic, but has spread over several countries or continents, usually affecting a large number of people.
- 4. Movement or change in frequency over time, usually upwards or downwards.
- 5. An organism (e.g., bacteria, viruses, parasites, or fungi) that causes disease in people or other living organisms.
- 7. A higher number of cases than expected in an area within a certain time period.
- 10. The natural habitat (e.g., an animal, water, or soil) where an infectious agent lives, grows, and multiplies.
- 12. The study of disease and other health outcomes, their occurrence and causes in a population, and the application of this study to control health problems.
- 15. A single instance of disease, injury, or other health condition that meets selected criteria of clinical and laboratory findings and for person, place and time.
- 17. A quantity measured per unit of something else (e.g., miles per hour). In public health, this is often number of cases that occur in a defined population over a specified period of time (e.g., 70 new cases of cancer per 1,000 people in a certain county per year).
- 19. The constant amount of a specific disease that is usually present in a geographic location, like a state or country.
- 20. A protein found in the blood that is produced in response to foreign substances (e.g., bacteria or viruses) invading the body.
- 22. A molecule usually found on the surface or produced by an infectious agent and that stimulates the production of a specific antibody.
- 23. A person who has been infected with an infectious agent (such as a virus) who does not experience symptoms of disease during the infection.
- 25. Any physical indication of disease seen by a patient or health care provider.
- 27. To be not affected or harmed by something. For example, antibiotic-resistant bacteria that develop the ability to not be harmed by the medicine (e.g., antibiotics) designed to kill them.
- 28. Sickness, illness, or loss of health.
- 29. The likelihood that an individual will experience a certain event that will cause injury, illness, or other unintended outcome.
- 30. A particular segment of a DNA molecule that determines the nature of an inherited trait, such as what a person might look like and whether a person might have or be likely to have certain diseases.
Down
- 2. Small living things (e.g., viruses, bacteria, or fungi) that are so small they can only be seen with a microscope.
- 3. A combination of signs and symptoms characteristic of a disease or health conditions.
- 6. The process by which an infectious agent is spread to a susceptible host.
- 8. A person or other living organism that can be infected by an infectious agent under natural conditions.
- 9. A person who has been infected with an infectious agent (such as a virus) and is showing symptoms of disease. A symptomatic person can spread disease.
- 11. Similar to an outbreak, but with a larger number of cases or occurring over a greater area or both.
- 13. The process of identifying a disease, condition, or injury from its signs and symptoms. Laboratory tests can be used to help with this process.
- 14. Any indication of disease felt by a patient.
- 16. A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease.
- 18. A living organism that carries an agent from a reservoir to a susceptible host.
- 21. Resistance developed in response to an antigen, often through infection or vaccination.
- 24. A group of cases of the same general health problem that occur in a limited geographical area without regard to the expected levels.
- 26. The invasion and growth of organisms (e.g., bacteria, viruses, parasites, or fungi) in the body that can cause disease.
