Giardiasis, 2010

During 2010, 846 cases of Giardia infection (16.1 per 100,000) were reported. This represents a 25% increase from the 678 cases reported in 2009 but a 22% decrease from the median number of cases reported annually from 1998 through 2008 (median, 1,082 cases; range, 678 to 1,556). Historically, a substantial proportion of Giardia cases has represented positive tests during routine screenings of recent immigrants and refugees.

The median age for all cases reported in 2010 was 17 years (range, 1 month to 96 years). Twenty-four percent of cases were less than 5 years of age, and 19% of cases were over 50 years of age. There was one outbreak of giardiasis identified in Minnesota in 2010; this was an outbreak associated with drinking water from a campground well.
