"Doctor," says the client, "I'm pregnant and I've just learned about cats carrying Toxoplasma. Should I get rid of my cat?"
"Let me ask you a few questions and we can discuss your exposure risk. Time out," says the student physician, and the actress playing the client closes her eyes. He turns to the student veterinarians. "What else would you discuss with her?"
We all start bringing up the other risks to mitigate, including her well water, raw milk, unwashed garden veg, goat placentas on her farm that she typically handles without gloves...
http://www.vetmed.ucdavis.edu/whatsnew/article.cfm?id=2702 The med students apparently LOVED this exercise. We had a great time with it as well; it's fascinating to get a glimpse of how zoonotic disease is handled from the human-med side. The "client" turned out to test positive for long-ago Toxoplasma exposure, meaning the risk to her fetus was comparatively minuscule. And of course after we were done, a whole bunch of med students trooped upstairs to pet some orphan kittens!
