Utah Weekly Weekly Cryptosporidiosis Surveillance Update
2018-09-01: MMWR1 Week 35
Background: Cryptosporidium is a parasite that is found worldwide and in every region of the United States (U.S.). When ingested, this parasite causes the diarrheal illness cryptosporidiosis (often called “crypto”). It is estimated that 800,000 cases occur each year in the U.S., though only a fraction of those are reported. On average, Utah has less than 100 reported cases per year, but in 2007, Utah experienced one of the largest cryptosporidiosis outbreaks in U.S. history with over 3,500 cases. Cryptosporidiosis is easily transmissible and can result in severe illness. Correct diagnosis, early detection of cases, and interview of ill persons is crucial in identifying sources of illness and preventing future cases and outbreaks.
