Fordham Tick Index

The Weekend Deer Tick Index

November 15 though 17, 2019:

Tick Index

The Fordham Tick Index is an estimate of the risk of being bitten by a nymphal or adult deer tick. Both of these stages are active at this time of year, although the smaller nymph is responsible for many more cases of Lyme disease. This index measures risk relative to other times of year. For more information about preventing tick bites, controlling ticks, Lyme disease and other illnesses ticks carry, visit the Centers for Disease Control and Prevention.

The Fordham Tick Index is provided as a weekly public service by Fordham University and is based on both current and historical data from one site in Westchester County, N.Y. It is an estimate only. Actual risk may vary geographically. Therefore, always take precautions to prevent tick bites when outdoors.

Regional Map for Tick Index including:  Manhattan, Bronx, Queens, Brooklyn, Staten Island, Nassau, Suffolk, Hudson, Essex

Tick Fact of the Week

Ticks have an immune system ready to repel bacteria and fungi that pose a danger. The Australian paralysis tick (Ixodes holocyclus), for instance, has small proteins called defensins that are active against Staphylococcus and Listeria bacteria as well Fusarium fungi.
