What's the word or name of someone who "gets sick" just by talking about it but they're not really sick?

I know a person that I can say: "The flu is going around again" and next day he has the flu, but two days later he out in the woods hunting. If he comes in contact with someone that has heartburn then the next day he has heartburn! I called him on the phone and told him I had a cold, the next day he had the cold... I can go on and on and on...

This has been a fact for many many years. Is there a name for a person like this or is it some type of disease?

He could be a hypochondriac. Or you could be suffering from a cognitive bias. Or a combination of both.

Pyschosomatic is the answer they are seeking. Hypochondriac is really reserved for people who are worried about getting sick. That is as opposed to the manifestation of illness from thinking about it. But, yes, hypochondriacs are at great risk for this phenomenon.
