Table 1. Results of binary classification tests for Peruvian districts, 2005–2012 –Level 1.

Binary Classification Tests		Classification Criteria		Classification Outcome
Test #	Weather Component	Weather Condition	Minimum Annual Duration (weeks)	Sensitivity (True Positives Identified)	Specificity (True Negatives Identified)	Overall Misclass Rate
Best performing classification using multiple weather components combined:
1	Minimum temperature	>14°C	33 weeks	0.95	0.95	0.05
	& Mean temperature	>22°C	7 weeks
Best performing classification using individual weather components:
2	Mean temperature	>22°C	11 weeks	0.91	0.95	0.06
3	Minimum temperature	>15°C	32 weeks	0.91	0.95	0.06
4	Mean humidity	>72%	17 weeks	0.88	0.83	0.16
5	Minimum humidity	>56%	8 weeks	0.82	0.79	0.21

Results of classification of 1557 Peruvian districts into dengue-positive and dengue-negative status for 2005–2012 are shown for best performing classification using a combination of weather criteria and best performing classification using individual weather components as inputs.
