Public Health Case Study

Case Investigation Process Models


Public health is the science and art of preventing disease, prolonging life, and promoting health through assessment, policy development and assurance for both communicable and non-communicable diseases alike. The ability to access and use data as close to "real time" as possible is essential in ensuring timely and appropriate public health responses to emergent situations impacting both disease and the environment. Ultimately this is about empowering the ability to assess, evaluate, and respond to protect individuals and populations to mitigate or prevent disease.

Appropriate interventions to target spread and management of infectious diseases hinge upon the ability to expedite case investigation of positive reportable lab results and to provide timely evaluation and response to immediate needs. Whether protecting individuals and community or mitigating and preventing outbreaks, public health efforts have historically been hindered as a result of variations and inconsistencies in processes, workflows and data. While specific case investigations and subsequent contact tracing may vary based on the disease and situation, the process of case investigation and contact tracing (CI/CT) is foundationally similar.
