The Asian long-horned tick, first reported on a sheep at a farm in New Jersey last summer, has now been reported in a total of seven states, from New York to North Carolina and as far west as Arkansas. The ticks are capable of carrying zoonotic viruses and other parasites, although no pathogens have been isolated from the ticks in the US so far.
