Deer Tick population soaring in RI
Risk of contacting Lyme Disease is especially high
SOUTH KINGSTOWN, R.I. (WPRI-tv.com) - A University of Rhode Island entomologist is warning that deer tick numbers in Rhode Island are up significantly, so the risk of contracting Lyme disease or other tick-borne diseases is especially high.

The number of deer ticks is 80% over 2011 levels and 142% above the previous 5-year average.
Thomas Mather, director of the URI Center for Vector-Borne Disease and the TickEncounter Resource Center, reports that his tick surveillance team has completed the first round of tick sampling at all 60 of the sites monitored for the past 18 years, and he is alarmed at this year's increases.

At one site in East Greenwich where sample counts are typically 14-20 nymphal deer ticks in 90 samples, this year the team collected 187 ticks.
Sites in Bristol, Tiverton and Johnston, among other places, also saw triple digit percentage increases compared to last year.
A second round of surveillance has already begun, and so far, the counts are coming in higher than in round one.
Mather said that unlike other models used to predict tick encounter and Lyme disease risk, his research has shown that nymphal deer tick abundance and disease rates are determined by relative humidity levels in June.
Higher humidity means greater tick survival, more tick encounters and more disease. Episodes of low humidity, even as brief as 8-10 hours, causes nymphal deer ticks to dry out and die earlier in the tick season.

At the event, Sen. Reed will call for a national strategy to combat the disease and expand federal research efforts to increase surveillance and prevention

TickSmart tips :
- Pay closer attention to the type of tick you come in contact with
- Do daily tick checks
- Always wear tick repellent
