  1. aSome records had missing values for exposure variables, including 4 for “hospitalized at pediatric department, Lyantonde Hospital”, 1 for “went to communal water point”, 2 for “went to church”, and 2 for “went to school”. These records were excluded from the respective analysis
  2. bOR = Crude odds ratios from univariate conditional logistic regression analysis, in which the matching variable was the case-control set
  3. cORadj = Odds ratios from multivariable conditional logistic regression
  4. dCase-patient’s likely exposure period = 7–21 days (minimum-to-maximum incubation periods) before case-patient’s rash onset
