Deer Tick Surveillance: Adults (Oct to Dec) excluding Powassan virus: Beginning 2008
health.data.ny.gov | Last Updated 16 Mar 2023This dataset provides the results from collecting and testing adult deer ticks, also known as blacklegged ticks, or by their scientific name <i>Ixodes scapularis</i>. Collection and testing take place across New York State (excluding New York City) from October to December, when adult deer ticks are most commonly seen. Adult deer ticks are individually tested for different bacteria and parasites, which includes the bacteria responsible for Lyme disease. These data should simply be used to educate people that there is a risk of coming in contact with ticks and tick-borne diseases. These data only provide adult tick infections at a precise location and at one point in time. Both measures, tick population density and percentage, of ticks infected with the specified bacteria or parasite can vary greatly within a very small area and within a county. These data should not be used to broadly predict disease risk for a county. Further below on this page you can find links to tick prevention tips, a video on how to safely remove a tick, and more datasets with tick testing results. Interactive charts and maps provide an easier way to view the data.
This dataset has the following 11 columns:
| Column Name | API Column Name | Data Type | Description | Sample Values |
|---|---|---|---|---|
| Year | year | text | Year in which ticks (all species and life stages) were collected. | 2015 2014 2020 2016 2017 view top 100 |
| County | county | text | The county where ticks (all species and life stages) were collected. Ticks are often collected from multiple publicly accessible sites in each county. | Dutchess Albany Columbia Onondaga Rockland view top 100 |
| Total Sites Visited | total_sites_visited | number | The total number of publicly accessible sites visited in the county. For the adult dataset, this means publicly accessible sites visited from October to December. | 1 2 3 4 5 view top 100 |
| Total Ticks Collected | total_ticks_collected | number | The total number of ticks (all species and life stages) collected in the county during visits to publicly accessible sites from October to December. | 0 1 51 52 2 view top 100 |
| Tick Population Density | adult_density | number | The average number of adult deer ticks (also known as blacklegged ticks or their scientific name Ixodes scapularis) collected per 1,000 meters sampled in the county. Tick population density is calculated only from the total adult deer ticks collected (and does not include other species or life stages collected at the time of the site visit). Note: When taken in conjunction with percentage of adult deer ticks positive (or proportion infected) with the specified bacteria or parasite, this field can give a sense of risk of encountering an infected tick. But tick population density and proportion infected can vary widely at different publicly accessible sites within a county, as well as from year to year. Statewide tick surveillance and testing began in 2008. | 0 1 50.00 2 16 view top 100 |
| Total Tested | total_tested | number | Total number of adult deer ticks that were tested for the listed bacteria or parasites. Ticks are tested individually. | 50 0 51 52 100 view top 100 |
| B. burgdorferi (%) | b_burgdorferi | number | Percentage of adult deer ticks that tested positive (or proportion infected) for Borrelia burgdorferi, the bacteria that causes Lyme disease. Note: When taken in conjunction with tick population density (or population size), this field can give a sense of risk of encountering an infected tick. But tick population density and proportion infected can vary widely at different publicly accessible sites within a county, as well as from year to year. | 0.0 50.0 56.0 60.0 46.0 view top 100 |
| A. phagocytophilum (%) | a_phagocytophilum | number | Percentage of adult deer ticks that tested positive (or proportion infected) for Anaplasma phagocytophilum, the bacteria that causes anaplasmosis [or human granulocytic anaplasmosis (HGA)]. Note: When taken in conjunction with tick population density (or population size), this field can give a sense of risk of encountering an infected tick. But tick population density and the proportion infected can vary widely at different publicly accessible sites within a county, as well as from year to year. | 0.0 4.0 6.0 2.0 10.0 view top 100 |
| B. microti (%) | b_microti | number | Percentage of adult deer ticks that tested positive (or proportion infected) for Babesia microti, the parasite that causes babesiosis. Note: When taken in conjunction with tick population density (or population size), this field can give a sense of risk of encountering an infected tick. But tick population density and proportion infected can vary widely at different publicly accessible sites within a county, as well as from year to year. | 0.0 2 8 10.0 4.0 view top 100 |
| B. miyamotoi (%) | b_miyamotoi | number | Percentage of adult deer ticks that tested positive (or proportion infected) for Borrelia miyamotoi, the bacteria that can cause a relapsing-fever like disease with symptoms like those seen in anaplasmosis patients. Note: When taken in conjunction with tick population density (or population size), this field can give a sense of risk of encountering an infected tick. But tick population density and proportion infected can vary widely at different publicly accessible sites within a county, as well as from year to year. Testing of ticks for B. miyamotoi started in 2015. | 0.0 2.0 4.0 1.0 0.9 view top 100 |
