Thought I would start the Disease Detectives marathon!

Here's something easy:

Give an example of a possible chain of infection for salmonella.

A hypothetical outbreak of cholera occurs in Sciolyville, NC. Some attendees of a picnic on an afternoon on May 17, 2020 were reported experiencing symptoms of diarrhea, vomiting, and dehydration. It was later reported that water served at the picnic had come from a nearby river. The following data was collected on six potential cases that attended the picnic:

--------Initials---Onset----Diagnosis----Diarrhea? --Vomiting?--Dehydration?--Lab testing

• ES-----May 18----cholera--------yes-----------no--------------yes----------pending
• BR-----May 17-----none------------no----------no--------------yes-----------positive
• PK-----May 18-----cholera--------no-----------yes-------------yes-----------not done
• GH-----May 19----cholera--------yes-----------no--------------no------------negative
• LF------May 18----cholera--------yes----------yes-------------yes-----------pending
• ZY------May 17-----none----------yes-----------no-------------yes-----------positive

Write a case definition for this outbreak, then list all six potential cases as either confirmed, probable, or possible.
