Table 3
Results of Mann-Whitney test for temporal changes in onset-to-diagnosis time of 473* confirmed SARS case-patients with onset of illness during period 1,† period 2, and period 3, 2003
| Interval (d) | Period 1 (N = 161) | Period 2 (N = 146) | Period 3 (N = 166) | Mean difference (p value) |
|---|---|---|---|---|
| Onset to diagnosis | 3.6398 | 2.0959 | – | 1.5439‡ (< 0.0001) |
| Onset to diagnosis | – | 2.0959 | 2.6024 | 0.5065 (0.0722) |
*5 cases deleted because of missing information on the relevant dates and 2 case-patients deleted because their onsets of SARS did not occur during the 3 periods of 2/25–6/15.
†Period 1 (2/25–4/27), time from onset of first case to the day before implementation of intervention measures including level B quarantine; period 2 (4/28–5/9), time from implementation of intervention measures to the implementation of expedited classification procedure; period 3 (5/10–6/15), time of the expedited classification procedure to the date of onset of the last SARS case.
