Fordham Tick Index
The Weekend Deer Tick Index
For the weekend of May 23 and 24, the tick index is:
4 out of 10
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.
01 = Low risk.
Enjoy the outdoors, but take precautions.
05 = Moderate risk.
Ticks are fairly abundant. Use caution.
10 = High risk.
Limit exposure and use extreme caution. If you're thinking of taking a hike, consider going to a movie instead.
Tick Fact of the Week
Blacklegged (deer) ticks can be infected with five different human pathogens, the most important being the spirochete that causes Lyme disease. But this tick keeps those spirochetes in check by producing antibacterial proteins that target the disease agent. The tick’s immune system is using bacterial genes acquired hundreds of millions of years ago to make the proteins it needs to fight its own invading bacteria.
