WGU D028 Crab Apple Valley (Latest
2025/ 2026 Update) Advanced Health
Assessments for Patients and
Populations (Verified Solutions)
.E1:Case definition is :
Person: who was the person that started the outbreak?
Place: where did the outbreak happen at?
Date : give a date of ehwn the si=ymptoms first began
Signs and symptoms: what did the patient signs of symptoms
E2: 10 steps of outbreak investigation w/examples
F1 Surveillance methods
You need to talk about two type of survwlliance methods
1. active survelliance ( look for the examples under each type)
2. passive surveillance methods.
F2. Suspected cases- here you need to show math.
The suspected cases for this scenerio were ____+____=___
F3. Probable cases
The probable cases for this scenerio were_____+_____=____
F4 mode of transportation both locations
1. Manny mode of transportation was considered:_______
2. famermarket and community hospital mode of transportation was considered_____.
(describe how each mode of transporataion was done for outbreak to happen.)
F5. Utilization of cumulative incidence. ( describe what cumulative incidence is and what it does. And what
happened in this scenerio)
, lOMoARcPSD|54441716
F6. Calculation of cumulative incidence
The calculation of the cumulative incidence for the entire outbreak scenario-- show your work!
# (total plague case)new cases of disease = __93____= 0.000744 X1000 =0.744 (answer)
# (total population size )candidate population 125,000
G1. Research project purpose statement this is the exact one from the slides.
A person will be considered a suspect if a person has had contact with a person who has contacted yersinia
pestis and if they went to the Farmer's market or community hospital on or after August 1, 2021. A person may
exhibit the symptoms of a fever, with or without painful swollen lymph nodes, chills, cough, and weakness.
G2. Data collection -self explanatiory the whole scenerio inclusing passive and active survellience
G3 outbreak scenerio ( aka histogram)
G3a significance of epi curve: tell what is does and why it important in an outbreak. (look up on google epi
curve)
G4.Incubation period: tell the TOTAL INCUBATION PERIOD for both crab apple valley &community
hospital. Hint: it on the histogram. (Aug1st to Aug 2=1 day. That mean Aug 2nd to 3rd -2nd day and etc) font look
at overlapping days. Just dates)
, lOMoARcPSD|54441716
G5 DIFFERENCES BETWEEN OUTBREAK TYPES
Decribe each outbreak types and definition
Endemic:
Epidemic:
Pandamic:
G5a. DISCUSSION OF OUTBREAK TYPE: THEY WANT TO KNOW WHAT TYPE OF OUT
BREAK WAS THEIS SCENERIO
G6. CASE FATALITY RATE (SHOW YOUR WORK)
G6a CASE FATALITY RATE SIGNIFICANCE:
LOOK UP ON WHAT THE SIGNIFICANCE OF THE CASE FATALITY RATE TELLS A PERSON
G7. PRIMARY AND SECONDARY RATES (SHOW YOUR WORK) IT IS THE CASE FATALITY
CHART ABOVE
-Primary attack rate (crab apple valley)
Number of plagues cases in crab valley
Divide by__________________________________ = _______X1000= answer
Number of people at risk in crab apple
-Secondary attack rate for the hospital
# of plagues cases in hospital
Divide by_______________________ = _______X1000= answer
# of people at risk in hospital
G7a: Occurrence of attacks
tell where primary and secondary attack occurred (hint: farmers market and hospital) and decribe how the
outbreak spread at each place.
H1. outbreak managemnt priniciples ( explain the 3 ways you would deal with outbreak.)
, lOMoARcPSD|54441716
H2. PUBLICIZING INFORMATION PLAN:
THIS YOU TELL HOW YOU WOULD INFORM THE PUBLIC ABOUT THE OUTBREAK, WHITHOUT
CREATING A PANAIC IN THE PUBLIC.
I. ANSWER THE FOLLOWING QUESTIONS
- what do you know now about investigating an outbreak that you did not know before? I
- what might you do differently if given the opportunity to investigate an outbreak?
- in what ways can you apply the concepts you have learned to your current clinical practice?
I hope this helps someone.
I will post my screen shots in a different file look on facebook group
1st tip is to take screenshots of all the screens. I say this so you will have something to refrence back to. ( to d
this you hold down the microsoft window logo and hit PrScr) this will put it under screenshots.
2nd tip is show your work for all calculations
3rd tip labela each power point slide that go with the scenerio ex. Label each slide in a corner with the number
that it goes withfor example E1, goes with E1 slide.E2 etc..)
4th do this on ms word this way you can spell check, yest they check and will send back for incorrect spelling
