During epidemics of cholera in two rural sites (Bakerganj and Mathbaria), a much higher proportion of patients came for treatment with severe dehydration than was seen in previous years. V. cholerae O1 isolated from these patients was found to be El Tor in its phenotype, but its cholera toxin (CT) was determined to be that of classical biotype. Whether the observed higher proportion of severe dehydration produced by the El Tor biotype was due to a shift from El Tor to classical CT or due to other factors is not clear. However, if cholera due to strains with increased severity spread to other areas where treatment facilities are limited, there are likely to be many more cholera deaths.

Drinking behavior among Muslim college students in the United States is unknown. To obtain estimates and examine risk factors, the authors conducted secondary data analysis of the public access database from the 2001 Harvard School of Public Health College Alcohol Study. Two variables were associated with drinking-religious activities, which were protective against drinking, and parental approval of drinking, which was a risk factor for drinking. Although American Muslim students had a low rate of drinking in the past year (46.6%) compared to their U.S. college counterparts, they had a higher rate of alcohol consumption compared to their counterparts in predominately Muslim countries.
