Officials look for source of Kansas cryptosporidium outbreak
Officials in Lawrence, Kan., are assuring residents the city water supply is safe, but they still have not determined the source of a cryptosporidium outbreak first reported on August 22. There have been 23 confirmed cases, and health officials believe there probably will be more. The diarrhea-causing parasite can be fatal to people with weakened immune systems, particularly those with HIV, the elderly, and children. "We are working as hard as we can, and we hope to have some results [on how far the parasite has spread] in the next few days," said Gianfranco Pezzino, the Kansas state epidemiologist.
