Wilfried Haas just told us that he has twice been infected with S. mansoni
in the course of research.
To determine the relative frequency of such accidental infections, please
send a message to me if you or someone you know has been so infected? Do you
know of travellers from non-indigenous countries who have become infected
while away from home? I will wait a couple of weeks then send the results
of this mini-survey to you.
