Association between measles and exposures during an outbreak: Lyantonde, Lwengo and Rakai districts, Uganda, June–September 2017

Exposurea	% cases (n = 34)	% controls (n = 136)	OR b (95% CI)	ORadjc (95% CI)
Exposures during case-patient’s likely exposure periodd

Visited any health facility	59	36	2.6 (1.2–5.5)
Went to communal water point	12	39	0.14 (0.039–0.51)	0.056 (0.0066–0.47)
Went to church	38	61	0.36 (0.16–0.81)

^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

^bOR = Crude odds ratios from univariate conditional logistic regression analysis, in which the matching variable was the case-control set

^cOR_adj = Odds ratios from multivariable conditional logistic regression

^dCase-patient’s likely exposure period = 7–21 days (minimum-to-maximum incubation periods) before case-patient’s rash onset
