Norovirus found to cause traveler's diarrhea

study and a PhD-candidate in the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health, noted that 11 Norovirus-positive stool samples also were positive for E. coli, a leading bacterial cause of traveler's diarrhea, thus indicating that dual infections among individuals experiencing traveler's diarrhea may be more common than previously thought.

The authors said that further research into the role of Noroviruses in traveler's diarrhea is warranted. The simple, inexpensive molecular diagnostic techniques used in this study to identify Norovirus-positive stool samples could serve to facilitate future Norovirus-related research in developing countries.

"Prevalence of Norovirus among U.S. Visitors to Mexico and Guatemala Experiencing Traveler's Diarrhea" was supported by a grant from the Center for a Livable Future at the Johns Hopkins Bloomberg School of Public Health. Amy R. Chapin was also supported by a Howard Hughes Medical Institute Pre-doctoral Fellowship in Biological Sciences.

Co-authors of the study were Colleen M. Carpenter, William C. Dudley, Lucy C. Gibson, Rafael Pratdesaba, Olga Torres, Domingo Sanchez, Jaime Belkind-Gerson, Irene Nyquist, Anders Karnell, Bjorn Gustafsson, Jane L. Halpern and A. Louis Bourgeois.
