Hi SS,
your right they are very common,if you can get a diagnosis from a dr.what if they have never tested us for them for years and years we would have a very long standing infection.then were screwed! i don't think these are the threadworms of old.evolution my dear watson!especially if they found a better hiding space one that goes undetected for say 20 to 4o years.think of the massive infection that would entail!
Threadworms: also known as Pinworms, Strongyloides stercoralis
