WGU D028 AJM3 TASK 1: C0MMUNICABLE OUTBREAK ASSESSMENT 2026 UPDATE | WITH COMPLETE SOLUTIONS

WGU D028 AJM3 TASK 1: C0MMUNICABLE OUTBREAK ASSESSMENT AJM3 TASK 1: COMMUNICABLE OUTBREAK ASSESSMENT C: This presentation will walk the audience through a plague outbreak scenario affecting the community of Crab Apple Valley. Information will be provided related to outbreak recognition, investigation, surveillance, control, prevention, and maintenance. The outbreak data used in this presentation were obtained from the Crab Apple Valley: Communicable outbreak simulation scenario video (Western Governors University [WGU], n.d.). 1 TOPIC OUTLINE Outbreak investigation steps Methods of surveillance Mode of transmission Study design and justification Incubation period Outbreak types Fatality rates Attack occurrence Outbreak control measures Reflection D: This presentation will discuss the components of the Crab Apple Valley outbreak scenario case definition, including clinical manifestations, lab diagnostics, and Person/Place/Time (PPT) distribution. There will be a description of the ten steps of an outbreak investigation with specific examples from this scenario, and the different methods of surveillance: passive versus active surveillance including a discussion of how they differ. Suspect and probable disease cases will be defined and differentiated, and related data from this outbreak will be presented. 2 Additionally, disease mode of transmission and utilization and calculation of cumulative incidence will be presented, along with a purpose statement for this disease outbreak investigation. This will be followed by a proposed study design and study design justification for this outbreak. A visual representation of collected data from this outbreak will be presented in the form of an epi-curve histogram along with disease incubation period information. This presentation will define the various outbreak types and the differences between them. Data about fatality rates, primary and secondary attack rates, and attack occurrence from this outbreak will be shared and discussed. 2 Outbreak control measures will be reviewed as well as the plan for information dissemination and communication. Finally, there will be a personal reflection of the Crab Apple Valley outbreak analysis and investigation. 2 KEY COMPONENTS OF A CASE DEFINITION OF AN OUTBREAK DISTRIBUTION: PERSON/PLACE/TIME E1: How is a case definition developed? There are three key components that go into an outbreak case definition. The first is clinical manifestations, which include signs and symptoms; distribution which include person/place/time elements; and diagnostic lab results. (Cantey & Gottesfeld, n.d.) In the Crab Apple Valley (CAV) outbreak of the plague, clinical manifestations of this disease outbreak include flu-like symptoms such as fever, chills, productive cough, tender and swollen lymph nodes, and weakness. The second key component is the distribution or person/place/time (PPT) component. In the CAV case definition this includes anyone with positive contact on or after August 1st at the CAV farmer’s market or the community hospital to which the responding emergency medical services team brought Jack, the farmer who was
