Asian longhorned tick is a growing threat in the US, but it's not the main threat

Risto0/iStock(WASHINGTON) -- The Centers for Disease Control and Prevention is alerting the public about the Asian longhorned tick, a species of tick not normally found in the United States that is known for its ability to mass-reproduce. Since its discovery in 2017, it has been spotted in several states, according to this week’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 the CDC’s Division of Vector-Borne Diseases in a press release. “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.”

There is a lot of mystery surrounding the Asian longhorned tick, so here’s what you should know.

The Asian longhorned tick can reproduce much faster than other ticks.

The Asian longhorned tick can produce offspring at 1,000 to 2,000 eggs at a time, just like the more than 850 other species of ticks. However, the Asian longhorned tick is unique in that it doesn’t need to mate to reproduce — it can do so all by itself. As a result, when an infestation occurs, thousands of ticks can end up on an animal or person from a single tick.

Nine states have reported Asian longhorned tick infestations.

New Jersey was the first state to report the tick after finding an infestation on a sheep. But since then, eight other states — Arkansas, Connecticut, Maryland, North Carolina, New York, Pennsylvania, Virginia and West Virginia — have reported finding the tick on a variety of hosts, including people, wildlife, domestic animals and in the environmental.

Experts from the local to the federal level are working to prevent the spread of illness.

To better understand the full potential impact of this tick discovery in the United States, the CDC says it is working with a network of federal, state, and local experts who specialize in veterinary and agricultural science and public health. Their goals include determining where the ticks are located, the kinds of pathogens they might carry that could infect people and how often they bite humans and animals. They also plan to develop prevention and control plans.

“In other countries, bites from these ticks can make people and animals seriously ill,” said Dr. Sloan Manning, medical director of Novant Health Urgent Care and Occupational Medicine in Winston-Salem, North Carolina, told ABC News. “As of October 2018, no harmful germs have been found in the ticks collected in the United States”

Though Asian longhorned ticks pose a threat, you should be looking out for all ticks.

Ticks are already very common in the U.S., living in areas with tall grass or around animals. They can’t survive without feeding on blood, so when they find a host, they latch on and stay on.

Though ticks are often associated with Lyme disease, Rocky Mountain spotted fever, and Ehrlichiosis, Manning said that most of them won’t be carrying these illnesses. Still, it’s important to remove them as the longer they stay on, the more likely they are to transmit a disease — if they are carrying one.

“It takes several hours for a tick to transmit bacteria into the skin,” Manning said. “If you think it has been attached for more than 24 hours or if you’ve developed a fever, rash or other typical symptoms, you should seek medical attention.”

In most cases, however, “removing the tick using tweezers with firm pressure will do,” she added.

Here are some tips for avoiding tick bites:

• Avoid wooded, grassy or damp areas or places where you might encounter deer or other animals.

• Wear clothing and gear, such as boots, long pants, long-sleeve shirts and socks, that are treated with 0.5 percent permethrin.

• Apply insect repellent containing DEET onto exposed skin, and follow the instructions on the container. In general, repellents that contain 98 percent DEET will last about 10 hours, while those with seven percent DEET will last about two hours.

• Bathe or shower as soon as possible after coming indoors to wash off and more easily find ticks.

• Conduct a full-body tick check using a hand-held or full-length mirror to view all parts of your body, including under the arms, in and around the ears, inside the belly button, behind the knees, between the legs, around the waist and especially in the hair.

• Make sure your pets are treated monthly with flea and tick protection.
