During the latter half of 2007, the Salt Lake Valley Health Department (SLVHD) collaborated and coordinated with health officials and many community partners (including pool operators) across the Wasatch Front to investigate and control a large community-wide outbreak of cryptosporidiosis.

Statewide, over 1,900 people became infected with Cryptosporidium from June 1, 2007 to November 30, 2007. Health districts most affected included Salt Lake, Utah, Davis, Weber-Morgan and Bear River; cases were first reported outside of Salt Lake County.

Nationwide, the incidence of cryptosporidiosis has increased in recent years; an estimated 30 outbreaks occurred in 2007. The 2007 Utah outbreak was one of the largest community-wide outbreaks in United States history.
