Table 2. Key factors of Ebola transmission based on socioeconomic status (SES) of probable and confirmed cases 1 .
| High SES | Middle SES | Low SES | P-value 2 | |
|---|---|---|---|---|
| (n = 544) | (n = 1044) | (n = 456) | ||
| Number of Contacts (mean ± SD) | 7.41 ± 9.45 | 8.01 ± 8.53 | 10.31 ± 10.73 | <0.001 3 |
| Time to isolation (mean ± SD) | 4.58 ± 5.03 | 4.36 ± 3.15 | 5.33 ± 5.97 | 0.247 |
| Hospitalization (n (%)) | 140 (33.98) | 239 (27.86) | 99 (27.89) | 0.063 |
| Mortality (n (%)) | 205 (42.53) | 412 (41.70) | 199 (46.50) | 0.240 |
1 Continuous variables are presented in terms of mean and standard deviation per group; categorical variables are presented as number of individuals and percentage per group. Percentages are based on the number of individuals in the sample for whom care-seeking or mortality data were available.
2 P-values calculated using an analysis of variance with ordered levels for continuous variables and chi-square tests for count variables.
3 Statistically significant at the P = 0.05 level.
