Across
  1. 1. Similar to epidemic, but has spread over several countries or continents, usually affecting a large number of people.
  2. 4. Movement or change in frequency over time, usually upwards or downwards.
  3. 5. An organism (e.g., bacteria, viruses, parasites, or fungi) that causes disease in people or other living organisms.
  4. 7. A higher number of cases than expected in an area within a certain time period.
  5. 10. The natural habitat (e.g., an animal, water, or soil) where an infectious agent lives, grows, and multiplies.
  6. 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.
  7. 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.
  8. 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).
  9. 19. The constant amount of a specific disease that is usually present in a geographic location, like a state or country.
  10. 20. A protein found in the blood that is produced in response to foreign substances (e.g., bacteria or viruses) invading the body.
  11. 22. A molecule usually found on the surface or produced by an infectious agent and that stimulates the production of a specific antibody.
  12. 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.
  13. 25. Any physical indication of disease seen by a patient or health care provider.
  14. 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.
  15. 28. Sickness, illness, or loss of health.
  16. 29. The likelihood that an individual will experience a certain event that will cause injury, illness, or other unintended outcome.
  17. 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
  1. 2. Small living things (e.g., viruses, bacteria, or fungi) that are so small they can only be seen with a microscope.
  2. 3. A combination of signs and symptoms characteristic of a disease or health conditions.
  3. 6. The process by which an infectious agent is spread to a susceptible host.
  4. 8. A person or other living organism that can be infected by an infectious agent under natural conditions.
  5. 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.
  6. 11. Similar to an outbreak, but with a larger number of cases or occurring over a greater area or both.
  7. 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.
  8. 14. Any indication of disease felt by a patient.
  9. 16. A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease.
  10. 18. A living organism that carries an agent from a reservoir to a susceptible host.
  11. 21. Resistance developed in response to an antigen, often through infection or vaccination.
  12. 24. A group of cases of the same general health problem that occur in a limited geographical area without regard to the expected levels.
  13. 26. The invasion and growth of organisms (e.g., bacteria, viruses, parasites, or fungi) in the body that can cause disease.
