Table 1. Impact of measles infection.

Among confirmed measles cases (n = 203) Age under 7 years (n = 70) Age 7–12 years (n = 25) Age 13 years and over (n = 108)
Worst day (median, mean, mode) 5, 5.61, 4 5, 5.58, 5 6, 7.56, 5 5, 5.15, 4
Mean duration of perceived symptoms (95% CI) 13.8 days (12.6 – 15.1) 12.8 days (11.0 – 14.9) 13.5 (10.4 – 17.1) 14.4 (12.7 – 16.2)
Individuals reporting time off work or school 128 (63.1%) 26 (37.1%) 22 (88.0%) 80 (74.1%)
Mean time off work or school for patients (95% CI) 9.6 days (9.3 – 11.7) 8.6 days (6.8 – 10.5) 9.1 days (7.4 – 10.8) 10.1 days (8.8 – 11.5)
Individuals reporting time off work for primary caregivers 75 (39.6%) 31 (44.3%) 10 (40.0%) 34 (31.5%)
Mean time off work for primary caregivers (95% CI) 7.3 days (5.7 – 7.9) 7.0 days (4.9 – 9.2) 7.7 days (4.3 – 11.3) 7.2 days (5.0 – 9.5)
Individuals reporting at least one night in hospital 74 (36.5%) 23 (32.9%) 2 (8.0%) 49 (45.4%)
Number of nights spent in hospital (median, mean, mode) 4.0, 4.2, 1.0 3.0, 4.0, 1.0 4.0, 4.0, 4.0 4.0, 4.4, 1.0

The mean time off work or school for patients and for primary caregivers is the mean time for those who reported at least one day of absence. Likewise, the number of nights in hospital applies only to those individuals who reported at least one night in hospital. 95% confidence intervals of the mean are based on 1,000 bootstrap replications. The first column shows results for the whole sample; the subsequent 3 columns split the sample into the three age groups considered.
