The data are now complete for 95 counties in 8 states (as of March 1, 2019 - previously only a subset had been provided). There are at least two years of historical data for each participating county (2017-2018), but some have many more. The surveillance methods employed for each county are different and may vary over time (e.g. many counties do not trap in the winter months). The compiled data include indicators of trapping effort including trap type, number of collections, and number of trap nights by county. Forecasters should assume that trapping effort for each county will be similar in 2019 to what was reported for 2018. Forecasts for counties with substantially different trapping effort in 2019 will be analyzed separately and not included in overall scores.
The data are provided in standardized csv files below with one file for each state (including all participating counties). A detailed description of the fields included in these csv files is also included below.
Other data sources may also be used for forecasting. There are no restrictions as to what data may be used. Forecasters may use as many data sources as they wish, but all should be listed in the model description (see Participation page). Links to potentially useful environmental data sources are included below on this page.

The dataset includes monthly adult Ae. aegypti and Ae. albopictus trapping data by trap type. This includes data on the total trapping effort (number of sites, trap nights, and collections) and the collections of both species (number of positive collections and number of adults collected). Each line represents all collections for a single county in a single month with a single trap type. Note that some counties have multiple lines for a single month because they employed more than one trap type.
DESCRIPTION OF VARIABLES
state
State of collection
Examples: Florida, California
statefp
Two digit FIPS code for state of collection: https://www.census.gov/geo/reference/codes/cou.html.
Examples: 12, 06
county
County of collection, without the word "County"
Examples: Broward, Los Angeles
countyfp
Three digit FIPS code for county of collection: https://www.census.gov/geo/reference/codes/cou.html
Examples: 011, 037
year
Four digit year of collection
Examples: 2016, 2017
month
Numeric month of collection (1-12)
Examples: 1, 10
trap_type
Type of trap used for collection, includes:
- BGS: BG sentinel traps including those baited with CO2
- GAT: Traps that target gravid Aedes females with enclosed water containers including BGGAT and AGO traps.
- GRAV: Traps that target gravid females with open water containers including CDC gravid traps. These traps target Culex species but may also detect Aedes species.
- CO2: Traps baited with CO2 including CDC and ABC light traps and Fay-Prince traps (BG sentinel traps using CO2 are classified as BGS) .
For collections where only presence or absence was recorded, “-PRES” is included at the end of the trap type name.
num_sites
Number of distinct trap sites
num_collection_events
Number of distinct trap collections. This may be less than the number of trap nights when a trap was set for multiple nights.
num_trap_nights
Cumulative number of nights distinct traps were run at all sites
num_aegypti_collected
Number of collected mosquitoes identified as Aedes aegypti. This may not be available and marked as NA in the case that collections were classified as present or absent rather than counting the number of mosquitoes. If only presence or absence was recorded for a trap, that is indicated in num_collections_aegypti.
num_albopictus_collected
Number of collected mosquitoes identified as Aedes albopictus. This may not be available and marked as NA in the case that collections were classified as present or absent rather than counting the number of mosquitoes. If only presence or absence was recorded for a trap, that is indicated in num_collections_albopictus.
num_collections_aegypti
Number of collections where Aedes aegypti were detected.
num_collections_albopictus
Number of collections where Aedes albopictus were detected.
