ATLANTA (AP) Nearly 1 in 10 public swimming pools in the
Atlanta area tested positive for parasites that cause diarrhea
The research, conducted by the Centers for Disease Control, is
the first to measure the occurrence of the parasites in U.S. pools.
CDC researchers were looking for Cryptosporidium and Giardia
They tested water from 160 public pools in two Atlanta-area
counties from August through October 2006.
CDC officials refused to name the counties. Samples were taken
from municipal pools, private clubs and other nonresidential
The researchers found that 12 of the 13 positives came from
pools commonly used by children.
The CDC said people should shower before using public pools and
to stay out of pools if they or their children have had diarrhea.
