  • The biology and ecology of H. longicornis as an exotic species in the United States should be characterized in terms of its vector competence and vectorial capacity for tickborne pathogens known to be present in the United States (5)

  • The recently documented occurrence of H. longicornis in the United States presents an opportunity for collaboration among governmental, agricultural, public health agencies and partners in academic public health, veterinary sciences, and agricultural sciences to prevent diseases of potential national importance before onset in humans and other animal species

Summary

Morbidity and Mortality Weekly Report

Multistate Infestation with the Exotic Disease–Vector Tick Haemaphysalis longicornis — United States, August 2017–September 2018. Established, exotic species in Australia, New Zealand, and several island nations in the western Pacific Region Where this tick exists, it is an important vector of human and animal disease agents. From August 2017 through September 2018, vector and animal surveillance efforts resulted in 53 reports of H. longicornis in the United States, including 38 (72%) from animal species (23 [61%] from domestic animals, 13 [34%] from wildlife, and two [5%] from humans), and 15 (28%) from environmental sampling of grass or other vegetation using cloth drags or flags* or carbon dioxide–baited tick traps.† With the exception of one report from Arkansas, the remaining reports of positively identified ticks are from eight eastern states: New Jersey (16; 30%), Virginia (15; 28%), West Virginia (11; 21%), New York (three; 6%), North Carolina (three; 6%), Pennsylvania (two; 4%), Connecticut (one; 2%), and Maryland (one; 2%) (Figure). Ticks collected from a deer in West Virginia in 2010 and a dog in New Jersey in 2013 were retrospectively identified as H. longicornis
