Begin Interview:
Hello, my name is [state interviewer name]. I am from [INTERVIEWER HEALTH DEPARTMENT]. We are
contacting you because of your (your child’s) recent infection with Cyclospora, which is a parasite that
causes intestinal illness. We are trying to determine how people become infected with Cyclospora so we
can prevent others from getting sick.
You may have already been contacted by someone at the health department, but I would like to ask you
questions in a standard way about your (your child’s) illness, and about any travel you may have had or
foods you may have eaten before becoming ill. The interview will take about 21 minutes. Your help in
the investigation is very important. Your participation is voluntary, and you may refuse to answer any
question at any time. All information you give will be kept confidential to the extent permitted by law.
No individual names or other identifying information will be used in any official reports about the
results of the investigation.
Are you willing to participate in this investigation?
If yes: The questions relate to the 14-day period before you (your child) became ill. Therefore, it may
help to have a calendar, recent restaurant and grocery store receipts, or credit card statements nearby.
Do you need a few moments to get this information? [Then proceed to start of interview]
