In the report, “Recreational Water–Associated Disease Outbreaks — United States, 2009–2010,” an error occurred on page 8 in the ^§ footnote of the table. The second and third sentences of that footnote should read as follows: “Microcystin was considered a confirmed etiology if water testing detected ≥20 μg/L microcystin toxin in water samples collected during or within 1 day of the outbreak exposure period. Microcystin was considered a suspected etiology if water testing detected <20 μg/L microcystin toxin in water samples collected during or within 1 day of the outbreak exposure period.”

In the report, “Algal Bloom–Associated Disease Outbreaks Among Users of Freshwater Lakes — United States, 2009–2010,” an error occurred on page 14 in the third sentence of the first full paragraph. That sentence should read as follows: “Microcystin concentrations of ≥20 μg/L exceeded the WHO guideline for moderate health risks in four outbreaks (Table 3) (2).”

In the report, “Zinc Deficiency–Associated Dermatitis in Infants During a Nationwide Shortage of Injectable Zinc — Washington, DC, and Houston, Texas, 2012–2013,” on page 35, in the author list, the affiliation footnotes for two authors were incorrect. The author list should read, “Duke Ruktanonchai, MD¹, Michael Lowe, PhD¹, Scott A. Norton, MD², Tiana Garrett, PhD¹, Lamia Soghier, MD³, Edward Weiss, MD⁴, June Hatfield, MS³, Jeffrey Lapinski, MS³, Steven Abrams, MD⁵, Wanda Barfield, MD⁶” (Author affiliations at end of text).
