Gillette, WY – At least 19 people have now been diagnosed
with the parasite cryptosporidium in Campbell and Crook counties.
That's a nearly four-fold increase over the past week. And just three cases were diagnosed in all of Wyoming over all of last year.
The parasite causes diarrhea. Outbreaks often are linked to swimming pools and water parks, and the parasite can survive for days even in chlorinated swimming pools.
So far the source of the parasite has NOT been pinpointed.
Nola Wallace directs the Campbell County Health Department. She says most of the cases have been in children, but a few cases have turned up in adults.
