When I was a kid, I remember being dewormed about 3 times and I still remember the medicine, Vermox. The first time I freaked out because I saw the long worms come out And then some in my stool, but after that I was used to it. Now, as an adult I have crazy seasonal allergies, hopefully that wasn’t the cause.

Well the issue raised here in the OP is mostly third world issues and it can be very difficult both in distance, language, as well as local government issues, in assisting people in need.
