Wednesday & Thursday, May 15 & 16, 2013
Objectives: Students will graph statistical
data from an epidemic, calculate attack
rates, analyze graphical data, design an
experiment to investigate the source of a
causative agent of an epidemic, and
compare the characteristics of known
diseases with an unknown.

Investigation of an Unknown Disease
-Read the Background
-Read the Situation
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Defining a Case
- Formulate a working definition
Which group of symptoms would you use
to determine if a patient represented a
“case”?
Why would you not want to include a
symptom such as “sore throat” in your
definition?
Lab

Wednesday & Thursday, May 15 & 16, 2013
Making an Epidemic Curve
- Make a histogram
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Determining Attack Rate
- Attack rate is the proportion of the population that is atrisk for infection who actually develop the illness over a
period of time.
(Number of cases / Number of people exposed) x 100%
What is the attack rate for the employees at the time of your
arrival on Saturday? (show your work)
What information must you have to determine an attack rate for
the visitors? Why is it much easier to determine the attack rate
for the employees than for the visitors?
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Continuing the Investigation (part I)
What is the one thing that all cases appear
to have in common?
Formulate a hypothesis as to the source of
the illness. Back it up with evidence that
you have collected.
Lab

Wednesday & Thursday, May 15 & 16, 2013
Continuing the Investigation (part II)
What does this information tell you about
the transmission of the agent causing the
outbreak?
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Continuing the Investigation (part III)
How would you go about identifying visitors to
the health center?
Calculate the attack rate for visitors to the health
department. (show your work)
Why do you suppose that the attack rate is
considerably lower for visitors than it is for
employees?
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Continuing the Investigation (part IV)
Revisit the epidemic curve (histogram) you
began earlier.
Add the new information to your histogram.
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Continuing the Investigation (part V)
Are the epidemic curves for the employees and
visitors the same? Give a possible explanation
for this.
You now suspect that you are dealing with
something in the building itself that is causing
people to become ill.
What evidence points to this suspicion?
Lab

Wednesday & Thursday, May 15 & 16, 2013
Incubation Period and Source of the Disease (part I)
About how long does it take someone to come down
with the symptoms after being exposed?
Based on this information in the table, which disease
would you suspect as the culprit?
However, based on the other evidence you have
gathered, you choose to rule these out. Explain why.
Lab
8th Grade Science
Wednesday & Thursday, May 15 & 16, 2013
Incubation Period and Source of the Disease (part II)
If your suspicions are correct, where would you expect
the smoke to go?
What types of samples would you want to take to try to
identify the organism responsible for the outbreak?
Suppose you had some lab animals available for
testing the air conditioning system. Describe an
experiment that you could perform to determine if the
air conditioning system in the health department

Incubation Period and Source of the Disease (part III)
Suppose you had some lab animals available for
testing the air conditioning system. Describe an
experiment that you could perform to determine if the
air conditioning system in the health department
building is really responsible. Be sure to include
replication and controls in your design.
