Global Moran’s I values for dengue and chikungunya empirical Bayes (EB) smoothed disease rates, aggregated to health district, in each year in the study

Arbovirus	Year	Total cases	Moran’s I*	Z-score	P-value
Dengue	2013	526	0.290	5.77	< 0.001
Dengue	2014	147	0.103	2.22	0.026
Dengue	2015	58	0.166	3.35	< 0.001
Dengue	2016	386	0.330	6.43	< 0.001
Chikungunya	2014	57	0.06	1.30	0.192

P-values in bold indicate statistically significant results.

^*Moran’s I values range between -1 and 1, where negative values indicate dispersion and positive values indicate clustering.
