Dear James,
there is no reason to apologize concerning your question. This kind of
questions was one of the reasons for us to establish this newsgroup and I would
appreciate if more members of this newsgroup would participate in this way.
Recently, Ken Mott from the WHO has send a message to this newsgroup
concerning a new WEB PAGE that has been installed on cercarial dermatitis at:
http://www.aquatica.com at which he wrote a section concerning your problem. I
cannot remember details of this page but perhaps it could be of interest to you.
Sincerely
Christoph
