Tick Index
Adult deer tick

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.

Tick Fact of the Week

In Australia, koalas (Phascolarctos cinereus) were found to host Ixodes tasmani, a tick responsible for transmitting at least three different pathogens. While I. tasmani did not appear to negatively affect the koalas in this study, previous work suggests that heavy infestations might induce anemia and reduce fertility in some populations.
