I was being somewhat sarcastic when I said E. v. was a soil transmitted
helminth. The writer is correct that the eggs are infective almost
imediately. What I said is that E.v. can be considered a socially
transmitted infection as it goes through entire households once it is
introduced. And one becomes infected by oral ingestion of infective eggs
which is the same manner that one obtains all soil transmitted
helminths. After all, E. v. eggs are passed into the environment, settle
on what ever, and then are ingested. But thanks for keeping me honest.
