Methods

Vectorborne disease data from NNDSS were retrieved from 2004, the first year that both neuroinvasive and nonneuroinvasive arthropodborne viral (arboviral) diseases were nationally notifiable, through 2016, the most recent year for which complete data are available (https://wwwn.cdc.gov/nndss/conditions/notifiable). Data were tabulated by disease, vector type (i.e., mosquito, tick, or flea), state or territory of residence, and year. State health departments report human disease cases using standard surveillance case definitions that include clinical and laboratory criteria. For some diseases, data reported according to Council of State and Territorial Epidemiologists definitions as confirmed or probable have been combined; autochthonous and travel-associated cases have been analyzed together by state or territory in which they were found.

Chikungunya virus, Zika virus, and Babesia cases became notifiable after 2004; only those data in NNDSS are presented. Although dengue became nationally notifiable only in 2010, earlier national data were available from CDC's Dengue Branch and are included in this analysis.
