Data are presented as RNAemic donations per 100 000 (95% confidence interval).
Abbreviations: CHIKV, chikungunya virus; DENV, dengue virus; ZIKV, Zika virus.
Testing started in April 2016 and continued for 15 consecutive months. From July 2017, the periods July–October were not tested, since there is normally limited outbreak activity during these months.
