The Asian longhorned tick has been found in nine states. CDC
The Centers for Disease Control and Prevention (CDC) has warned of a "multistate infestation" with the Asian longhorned tick—the
first new tick species to enter the U.S. in 50 years.
New Jersey was the first state to report the
Haemaphysalis longicornis on a sheep in August 2017. Since then, it has been found in Arkansas, Connecticut, Maryland, North Carolina, New York, Pennsylvania, Virginia and West Virginia, according to Friday's Morbidity and Mortality Weekly Report.
