Diarrhea and Swimming Still Don't Mix.

The National Environmental Health Association strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we periodically feature columns on environmental health from the Centers for Disease Control and Prevention (CDC) in the Journal. In these columns, authors from CDC's Water, Food, and Environmental Health Services Branch, as well as guest authors, will share tools, resources, and guidance for environmental health practitioners. The conclusions in this column are those of the author(s) and do not necessarily represent the views of CDC. CDR Jasen Kunz is the healthy water lead in the Waterborne Disease Prevention Branch at CDC. CDR Joseph Laco leads recreational water initiatives at the National Center for Environmental Health within CDC.
