Abbreviation: CI, confidence interval. ^aA weighted cluster analysis was used to calculate the projected percentage. The weight for each household was calculated as follows: the number of households in the sampling frame (n = 122 339) / (number of household interviews completed in the cluster [range, 0-7] × number of clusters selected [n = 30]).

^bSurvey question: “Since the chemical spill on January 9, did anyone in your household have any health problem they felt was related to the chemical spill?” Time frame: date of chemical spill (January 9, 2014) through day of interview (April 8-10, 2014).

^cOf 39 households reporting household members with health issues.

^dEach household could have ≥1 member in each age group; therefore, there can be more members than households reporting members with health issues (n = 39).

^eRespondents could choose >1 answer.

^fOther symptoms reported included dizziness (n = 3), dry skin (n = 2), cellulitis (n = 1), “chest on fire” (n = 1), rapid heartbeat (n = 1), and unspecified (n = 1).
