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."

Ticks may not seem dangerous, but they can cause disease and even death in livestock and pets. There are hundreds of tick species in the world, about 10 percent of these species are found in the United States. Now there’s one more to watch out for. In 2017, the U.S. Department of Agriculture (USDA) confirmed the presence of the Asian longhorned tick (Haemaphysalis longicornis). It probably arrived in the United States in or before 2010. Exactly how or when is unknown, but one thing is certain: it may have entered on domestic pets, horses, livestock or people. While we know the impact of this tick in other parts of the world, we are still studying how they may affect U.S. agriculture, and our environment.
