The Centers for Disease Control and Prevention is working with public health, agricultural, and academic experts to understand the possible threat posed by the spread of the Asian longhorned tick (Haemaphysalis longicornis) in several U.S. states since its discovery in 2017, according to today’s Morbidity and Mortality Weekly Report. "The full public health and agricultural impact of this tick discovery and spread is unknown," said Ben Beard, Ph.D., deputy director of CDC's Division of Vector-Borne Diseases. "In other parts of the world, the Asian longhorned tick can transmit many types of pathogens common in the United States. We are concerned that this tick, which can cause massive infestations on animals, on people, and in the environment, is spreading in the United States."

In November of 2017, a tick species previously unknown to the US called Haemaphysalis longicornis, or the Asian longhorned tick, was discovered both on a sheep and in a pasture in New Jersey. Since then, this new tick species has been found in eight additional states, including 17 counties and one city in Virginia.

The Rhode Island Department of Environmental Management (DEM) today announced that the longhorned tick, an exotic pest from Asia, has been found for the first time in New England. Working in cooperation with the Animal and Plant Health and Inspection Service (APHIS) of the US Department of Agriculture (USDA), DEM is asking livestock producers and wildlife rehabilitators to observe animals for the presence of the tick.
The Asian longhorned tick is native to eastern Asia. It was first detected in New Jersey in 2017. The full public health and agricultural impact of this tick and spread is unknown. It is a potential vector of several human and animal diseases present in the U.S.
