Vaccinations, counseling to change high-risk behaviors, and sometimes chemoprevention are types of primary prevention. Although this sort of prompt and appropriate response addresses the possibility of continued transmission on the basis of known agent-specific facts and experience, epidemiologists sometimes need to extend the investigation, depending on the circumstances and needs (e.g., when a trace-back is indicated to identify a continuing primary source for a restaurant-associated outbreak, such as shellfish or lettuce that was contaminated before being harvested) (5). Deter through civil suits or criminal prosecution.
