Abstract

3 September 1979

To the Editor:

We have read the Presidential Address in the May 1979 issue of the , and would like to comment on it. We make these comments because we believe some of the statements in the Address, especially when made by a person of Dr. Kagan's international stature, reflect unfavorably on one of the most important tools for schistosomiasis transmission control.

In the Address, Dr. Kagan makes the assertion that “The control of schistosomiasis by mollusciciding, however, has proven to be essentially ineffective.” If he had added the qualifying statement: “where used in a haphazard manner, without appropriate precontrol studies,” then we might have agreed with him. Obviously, in any situation in which pesticides are used proper knowledge of the local epidemiology of any disease, then environmental impact on non-target species, lack of cost-effectiveness, development of target-species resistance, and failure to attain interruption of transmission may indeed occur.
