Epidemiological trends of the dengue importation into Taiwan. (A) The scatter plots show the relationship between the number of imported dengue cases, according to the viremic status as measured by a biweekly surveillance of the airport screening program, and the number of total dengue importations into Taiwan from 2007–2010. The straight line represents a line fitted by the means of a least squares regression. The coefficient of determination, R², was estimated to be 0.61 (n = 104, P < 0.0001). The 95% confidence interval of the slope is 1.42-1.94. (B) The scatter plots show the relationship, as measured by a biweekly surveillance, between the number of dengue importations detected in the airport screening program and the number of dengue importations detected in the community from 2007–2010. The straight line represents a fitted line by the means of a least squares regression. The coefficient of determination, R², was estimated to be 0.22 (n = 104, P < 0.0001). The 95% confidence interval of the slope is 0.44-0.96.
