| Term | Definition |
| Antigenic drift | Slow and progressive genetic changes that take place in DNA and RNA as organisms replicate in multiple hosts |
| Antigenic shift | Sudden change in the molecular structure of DNA and RNA in microorganisms, resulting in a new strain of the microorganism |
| Convergence model | Model illustrating the interaction of 13 factors that contribute to the emergence of infectious diseases |
| Directly observed therapy | Observation of clients to ensure that they ingest each dose of anti-TB medication to maximize the likelihood of completion of therapy |
| Ecosystem | Natural unit consisting of all living things (plants, animals, bacteria, viruses) interacting with, and dependent on, one another for survival within their nonliving environment |
| Emerging infectious disease | Newly identified clinically distinct infectious disease, or the reappearance (reemergence) of a known infectious disease after its decline, with an incidence that is increasing in a certain geographic area or among a specific population |
| Herd immunity | Type of immunity in which a large proportion of people in a population are not susceptible to a communicable disease and the few people who are susceptible will not likely be exposed and contract the illness |
| Microbial adaptation | Process by which organisms adjust and change to their environment |
| Pandemic | Epidemic occurring worldwide |
| Carrier | A person or animal that harbors an infectious organism and transmits the organism to others, although having no symptoms of the disease |
| Colonization | The presence and multiplication of infectious organisms without invading or causing damage to tissue |
| Common source outbreak | An outbreak characterized by exposure to a common, harmful substance |
| Contagious | Communicable by direct or indirect contact |
| Endemic | The constant or usual prevalence of a specific disease or infectious agent within a population or geographic area |
| Epidemic | Significant increase in the number of new cases of a disease than past experience would have predicted for that place, time, or 251 252 population; an increase in incidence beyond that which is expected |
| Healthcare-associated infection | Originating in a healthcare facility; formerly called nosocomial infection |
| Incubation period | Time period between initial contact with the infectious agent and the appearance of the first signs or symptoms of the disease |
| Infectious disease | Presence and replication of an infectious agent in the tissues of a host, with manifestation of signs and symptoms |
| Pathogenicity | Ability of the agent to produce an infectious disease in a susceptible host |
| Propagated outbreak | Outbreak resulting from direct or indirect transmission of an infectious agent from an infected person to a susceptible host; secondary infections can occur |
| Reservoir | Location where an infectious agent is normally found, where it lives and reproduces under normal circumstances |
| Secondary infection | Infections that occur within the accepted incubation period following exposure to a primary case |
| Surveillance | A continual dynamic method for gathering data about the health of the general public for the purpose of primary prevention of illness |
| Transmission | The transfer of an infectious agent from one person or place to another |
| Bioavailability | The amount of a substance that is absorbed or becomes available at the site of physiological activity |
| Biomonitoring | Process of using medical tests such as blood or urine collection to determine whether a person has been exposed to a contaminant and how much exposure he or she has received |
| Environmental epidemiology | Field of public health science that focuses on the incidence and prevalence of disease or illness in a population from exposures in their environments |
| Environmental health | A field of public health science that focuses on how the environment influences human health |
| Environmental justice | The belief that no group of people should bear a disproportionate share of negative environmental health consequences (regardless of race, culture, or income) |
| Exposure | The total amount of a contaminant that comes in direct contact with the body |
| Exposure estimate | Factors that determine a person’s level of exposure to a contaminant |
| Exposure pathway | Method by which people are exposed to an environmental contaminant that originates from a specific source |
| Exposure history | Process to help determine whether an individual has been exposed to environmental contaminants |
| Precautionary principle | If something has the potential to cause harm to humans or the environment, then precautionary measures should be taken even if there is a lack of scientific evidence for cause and effect |
| Healthy communities | Communities that optimize the physical, social, and economic environments of the community |
| Risk assessment | Process to determine the likelihood or probability that adverse effects such as illness or disease will occur in a group of people because of an exposure to an environmental contaminant |
| Toxicology | The study of the adverse effects of chemical, physical, or biological agents on people, animals, and the environment |
| After-action report | Retrospective analysis used to evaluate emergency response drills |
| Decontamination | Process of cleaning to remove biologic, chemical, or radiologic agents |
| Evacuation | Moving people from a dangerous place to safety |
| Incident command system (ICS) | Common organizational structure implemented to improve emergency response |
| Invacuation | Moving people from one area to another within the same facility |
| National Response Framework (NRF) | Framework that guides how the nation conducts all-hazards incident response |
| National Incident Management System (NIMS) | Structured, flexible framework that guides the response to disasters at all levels of government, the private sector, and nongovernmental organizations |
| Personal protective equipment (PPE) | Clothing and/or equipment used to protect the body from injury and illness |
| Point of distribution (POD) | Centralized location where the public picks up emergency supplies following a disaster |
| Real time | The actual time in which something occurs |
| Scenario | The sequence of possible events or circumstances |
| Shelter in place | The protective action of taking cover in a building |
| Simulation | The imitation of the features of an object or anticipated response |
| Surveillance | A process to document and track changing information to prevent injury and illness |
| Terrorism | The use of threats and/or violence to intimidate or coerce society for political purposes |
