• On April 5, 2007, the local health department in
  Rock county receives a call from a provider who
  has just diagnosed a case of hemolytic uremic
  syndrome (HUS) in one of his patients. The public
  health nurse takes down basic patient information
  and asks the doctor to report the case through
  the WEDSS system.

• On April 6, 2007 a provider in Marathon county
  reports another case of hemolytic uremic syndrome
  in a patient, the case is reported through the
  WEDSS system as well. At the same day 5 other
  patients around Wisconsin are diagnosed with
  hemolytic uremic syndrome.

• We can now use the AVR tools to plot the cases
  on a map to get an overview of the situation.

• The cases are identified as being part of an
  outbreak of E. coli and combined efforts to stop
  the outbreak are taken.
• To document these efforts the outbreak module of
  WEDSS is used

Health workers can now work together to
investigate and stop the outbreak from spreading
further.

Scenario 2

• Terry Hiltz

31

• Cases of E. coli O157H7 are reported through
  the WEDSS system. On average, data trends show 2
  cases are reported monthly. 
• By using the AVR tool, we see an increased
  number of cases in February (compared to previous
  years)

33

• To further identify where all the cases are,
  they are plotted by zip code on a map.

35

• As more cases are reported, the graph shows a
  spike representing this increase in cases.

• We can look at the table used to create the
  graph and drill through to detailed case
  information, with appropriate permissions.

39

• The state lab is notified and asked to rush
  molecular analysis to determine if the cases
  could be linked.
• A link is identified and each of the health
  department jurisdictions with cases are contacted
  and an outbreak is created in WEDSS together with
  a questionnaire to identify possible sources of
  the outbreak.
• Once the source of the infection is found actions
  are taken to control the outbreak.

40

• Later, looking at the graph by month, we can see
  that the outbreak was contained.
