Table 2 Association between measles and exposures during an outbreak: Lyantonde, Lwengo and Rakai districts, Uganda, June–September 2017

Exposure^a	% cases (n = 34)	% controls (n = 136)	OR ^b (95% CI)	OR_adj^c (95% CI)
Exposures during case-patient’s likely exposure period^d
Hospitalized at pediatric department, Lyantonde Hospital	47	2.3	30 (7.0–132)	34 (5.1–225)
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)
Went to school	47	41	1.4 (0.55–3.6)
History of measles vaccination	26	76	0.11 (0.043–0.27)	0.051 (0.011–0.25)

^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
