Global Capacity for Emerging Infectious Disease Detection, 1996–2014
Table 7
Results of univariate Cox proportional hazards regression analyses, by quartile of change in Human Development Index (HDI) rank, in a study assessing global capacity for emerging infectious disease detection, 1996–2014
HDI rank change quartile | No. outbreaks* | Days to discovery hazard ratio (95% CI) | No. outbreaks* | Days to communication hazard ratio (95% CI) |
---|---|---|---|---|
Q1: Most improvement | 49 | 1.04 (0.98–1.09) | 49 | 1.04 (0.98–1.09) |
Q2: High-intermediate | 43 | 1.09 (1.03–1.15)† | 44 | 1.06 (1.00–1.12)† |
Q3: Low-intermediate | 60 | 1.08 (1.03–1.13)† | 61 | 1.07 (1.02–1.12)† |
Q4: Most decline | 120 | 1.05 (1.01–1.08)† | 121 | 1.00 (0.97–1.03) |
*Quartiles are defined based on all countries with HDI scores from 1990 and 2013, regardless of whether they had outbreaks. Therefore, outbreaks are not evenly distributed across the quartiles.
†Statistically significant (α = 0.05).
