There are many possibilities. I do not deny that some evidence exists for contagion. Contagion by itself is not evidence for anything at all, other than that illness may sometimes (though certainly not necessarily) have a common origin. Though what such an origin is has never been convincingly demonstrated . . . not even once. So it's anybody's guess what it might be. Women living together synchronize their menstrual cycle, but we don't jump to the conclusion that some particle jumped from one to the other. When someone nearby yawns or laughs, we start to as well, but we haven't "caught" anything material.

It could also be that families eat together, and so eat something bad together; live together, and so encounter the same environmental pollutants or toxins; experience the same stress together; and their bodies are constantly able to share information via chemical or energetic mechanisms.

Look up Terrain Theory versus Germ Theory, and you'll get some people's ideas who've put a lot of thought into this.

Contagion by itself is not evidence for anything at all other than that illness is not always a strictly individualized phenomenon (though it often is).
