Surveillance for waterborne disease outbreaks--United States, 1991-1992.

Abstract

The number of waterborne disease outbreaks reported per year has not changed substantially in the past 5 years. However, etiologic agents only recently associated with waterborne disease, such as E. coli O157:H7 and Cryptosporidium, are being reported more frequently and from new settings. Water quality data for outbreaks during the period 1991-1992 indicate that available water disinfection technology is not always in place or used reliably.(ABSTRACT TRUNCATED AT 400 WORDS)
