"Fascinating. Odd that so many of those who assume to have parasitic infections tend to also have hyper-sensitivities and allergies. Unclear from article whether this possible increase in production of interleukin10 by helminths in the body (in some) would effect allergies beyond hay fever. Unless I missed something."
I have read about the doctor who injecting himself with a parasitic worm in 1970 to cure his asthma. It could also be other way around. We live in too sterilized world that our body immune system has weakened. There was research where the children living in cleanest houses were more allergenic than children who's rooms were dirty.
