Tick Threat Expands: New Species Identified in Tennessee as ER Visits Surge

Nashville,TN – Public health officials are alerting residents too the presence of the longhorned tick,a species originating from East Asia,now identified in Tennessee. This progress comes amidst a nationwide spike in tick-borne illness cases, prompting increased concern and a call for proactive preventative measures.

The invasive tick, previously found in countries like New Zealand and Australia, has now been reported in 21 states, with recent sightings including Tennessee and Michigan. Experts beleive livestock may have facilitated its introduction into the united States.

What is the threat?

These ticks can transmit diseases causing severe symptoms, including high fever and reduced platelet counts. Dr. Jermaine Hogstrom of CHI Memorial Hospital warns that tick-bite symptoms can range from discomfort to significant illness. “A bite may develop redness around the site,” he explains, “but a developing rash anywhere on the body within 3 to 4 weeks is a more concerning sign.”

Emergency Room Visits Sharply Rise

Nationwide emergency room visits for tick-borne illnesses have increased dramatically this year. The Centers for Disease Control and Prevention (CDC) reports the number of cases in July eclipsed totals from the past eight years combined.

| Tick-borne Illness | Symptoms | Potential Complications |
|—|—|—|
| Rocky Mountain Spotted Fever | Fever, headache, rash | Organ failure, neurological problems |
| lyme Disease | Fever, fatigue, joint pain, bullseye rash | Arthritis, neurological issues, heart problems |
| Ehrlichiosis/anaplasmosis | Fever, headache, muscle aches | Respiratory failure, organ damage |

did You Know? The longhorned tick is unique as it can reproduce asexually. This means a single female tick can lay thousands of eggs without mating.

Prevention is Key

Health experts emphasize preventative steps to minimize risk during outdoor activities:

Repellent: Use tick repellent spray, particularly those containing DEET, permethrin, or picaridin.
Protective Clothing: Wear long-sleeved shirts and pants when possible.
Tick Checks: Thoroughly check yourself, your family, and pets for ticks after spending time outdoors.

Proper Tick Removal and Medical Attention

If a tick is found attached to skin:

Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
Pull upward with steady, even pressure.
Place the tick in a sealed plastic bag for identification purposes.
* Seek medical attention promptly, especially if symptoms develop.

Pro Tip: If you have concerns about a tick bite, it’s always best to consult a healthcare professional. Early diagnosis and treatment can prevent serious complications from developing.

If you do remove the tick at home, Dr. Hogstrom recommends properly identifying it to aid medical evaluation.

This latest news comes as the tick season is still prevalent, and public health officials urge vigilance and proactive measures in light of rising cases and a new species in the region.

A New Tick Species Emerges in Tennessee: Wildlife Biologist Highlights Potential Health Risks and Ecological impact

Identifying the new Tennessee Tick: Amblyomma aurisculatum

A recently identified tick species, Amblyomma aurisculatum, commonly known as the Gulf Coast tick, is establishing a foothold in Tennessee. While previously confined to the coastal regions of the southeastern United States, confirmed sightings and collections across several Tennessee counties signal a concerning range expansion. This poses new challenges for public health and wildlife management within the state. Initial detection occurred in the western part of tennessee, but reports are now surfacing from central and eastern counties. Accurate tick identification is crucial, as misidentification can lead to incorrect risk assessment and treatment.

Health Risks Associated with the Gulf Coast Tick

The Gulf Coast tick is an aggressive biter, known for its long feeding times. This prolonged attachment increases the risk of pathogen transmission. While Lyme disease is not currently a major concern with this species, the Gulf Coast tick is a known vector for:

Heartland Virus: A relatively newly discovered virus, Heartland virus can cause fever, muscle aches, fatigue, and in severe cases, hospitalization. There have been confirmed cases in Missouri,Oklahoma,Arkansas,Kansas,Kentucky,Tennessee,and Illinois.

Southern Tick-Associated Rash Illness (STARI): STARI presents with a similar rash to Lyme disease, but its cause is currently unknown. Symptoms include fever, fatigue, muscle and joint pain, and a characteristic expanding red rash.

Tularemia: A bacterial infection that can affect the skin,eyes,lymph nodes,and lungs.

Rocky Mountain Spotted Fever (RMSF): Though primarily transmitted by the American dog tick,the Gulf Coast tick can also carry Rickettsia rickettsii,the bacteria responsible for RMSF.

Tick-borne diseases require prompt diagnosis and treatment. Symptoms to watch for include fever, rash, headache, muscle aches, and fatigue. If you suspect a tick-borne illness, consult a healthcare professional immediately.

Ecological Impact on Tennessee Wildlife

the introduction of a new tick species can have significant repercussions for Tennessee’s diverse wildlife populations.

Livestock Impacts: Cattle, horses, and other livestock are notably vulnerable to heavy infestations, leading to anemia, weight loss, and reduced productivity.

White-tailed Deer: While deer can tolerate tick infestations better than livestock, heavy loads can still cause stress and potentially impact their overall health.

Bird Populations: Ticks can parasitize birds, especially ground-nesting species, potentially affecting chick survival rates.

Small Mammals: Rodents and other small mammals serve as significant reservoirs for tick-borne pathogens, amplifying the risk of transmission to humans and other animals.

The increased tick burden on wildlife can disrupt the delicate balance of the ecosystem. Monitoring wildlife populations for signs of tick-related illness is essential.

Tick Prevention Strategies for Tennesseans

protecting yourself and your family from tick bites requires a multi-pronged approach.

  1. Personal Protective Measures:

Wear light-colored clothing to easily spot ticks.

tuck pants into socks or boots.

Use insect repellents containing DEET, picaridin, or oil of lemon eucalyptus.

Treat clothing and gear with permethrin.

  1. Landscape Management:

Keep lawns mowed short.

Clear brush and leaf litter from around homes.

Create a barrier of wood chips or gravel between lawns and wooded areas.

  1. Tick Checks:

Conduct thorough tick checks on yourself, your children, and your pets after spending time outdoors.

Pay close attention to areas like the hairline, ears, armpits, groin, and behind the knees.

  1. Pet Protection:

use veterinarian-approved tick preventatives for pets.

Regularly check pets for ticks.

Current Research and Surveillance efforts

The Tennessee Department of Health and the University of Tennessee institute of Agriculture are actively involved in surveillance and research efforts to better understand the distribution and impact of the Gulf Coast tick. This includes:

Tick Dragging: Collecting ticks from various habitats to map their distribution.

Pathogen Testing: Analyzing ticks for the presence of disease-causing agents.

Wildlife monitoring: Assessing the prevalence of ticks and tick-borne diseases in wildlife populations.

* Public Education: Raising
