Cryptosporidiosis Surveillance --- United States, 2006--2008

Cryptosporidiosis Surveillance — United States, 2006–2008

During 2006–2008, the number of reported cases of cryptosporidiosis increased dramatically (79.9%), from 6,479 for 2006 to 11,657 for 2007, and then decreased (9.9%) to 10,500 in 2008. A greater number of case reports were received for children aged 1–9 years and for adults aged 25–39 years than were received for persons in other age groups. The increase in cases reported for 2007 and 2008 is partially attributable to multiple large recreational water-associated outbreaks. The seasonal and age-specific peak coincides with the summer recreational water season and likely reflects increased use of communal swimming venues (e.g., lakes, rivers, swimming pools, and water parks) by young children
