I will be hospitalized soon in Germany, where I live, and have noticed that German hospitals don't seem to have a protocol for handling patients with airborne food allergies in rooms with more than one patient. I have an airborne allergy to apples and it's a common food. How do American hospitals handle the problem? Do they put the patient in a private room? Do they control what the roommates eat? I'm curious because I'd like to make some suggestions to the hospital staff. The last time I was hospitalized, the staff left it up to me to discuss it with my roommates and all the visitors and ask them not to eat any apples in the room. But given that I might have to undergo surgery soon, I might not be in the condition to be so vigilant.
