Authorities say a tick that's been identified in nine states since last year has been found for the first time in New Hampshire on a dog visiting from out of state.
The dog was found to have an Asian longhorned tick. It had been visiting New Hampshire from an area in New York where the tick has been found.
The tick is native to Southeast Asia, where it has been a pest of livestock, wildlife, and household pets, although humans are not immune from it.
Authorities say to date no cases of harmful diseases have been found in these ticks in the United States, though it is known to transmit illness in other countries.
Studies show the tick has been present in the United States since at least 2010.
