Tick-Borne Diseases
From the Rhode Island Department of Health

will cause this kind of rash.
Tick-borne diseases are transmitted through the bite of an infected tick. 

These include Lyme diseaseAnaplasmosisEhrlichiosisBabesiosis, Powassan (POW), and Rocky Mountain Spotted Fever

Ticks can be infected with bacteria, viruses, or parasites. 

When an infected tick bites the human host, the human may become infected.

Symptoms

If you have been bitten by a tick, there is a possibility that have become infected with one of these diseases, but not every tick is a carrier.

If you have become infected, symptoms can present themselves between a few days and a few months later, or may not appear at all.

The type and severity of symptoms vary with the specific disease, but there are some common symptoms, which include tiredness, body/muscle aches, joint pain, fever, rash, stiff neck, and facial paralysis.

Early diagnosis is helpful in successfully treating tick-borne diseases, so it is important to contact your healthcare provider if you are experiencing symptoms.



How Tick-Borne Diseases Spread

Ticks feed on small wild rodents, deer, pets, and humans.

When a tick becomes infected and continues to feed on various hosts, the bacteria, virus, or parasite can be transmitted.

Ticks that are located in the brush and on tall grasses come into contact with humans as we pass through these environments.

The ticks can then crawl up sleeves and bite the skin, typically around warm areas under the hair.

Lyme diseaseAnaplasmosis, and Babesiosis are spread by the Deer Tick (Ixodes scapularis). 

Ehrlichiosis is spread by the Lone Star tick (Amblyomma americanum).

 Rocky Mountain Spotted Fever is spread by the American Dog Tick (Dercacentor variabilis), Rocky Mountain Wood Tick (Dermacentor andersoni), Lone Star tick (Amblyomma americanum), and Brown Dog tick (Rhipicephalus sanguineus).   

Powassan virus is spread by the Deer Tick (Ixodes scapularis), Ixodes cookie, and Ixodes marxi.  Ixodes cookei and Ixodes marxi rarely bite humans.

Lyme diseaseAnaplasmosis, and Babesiosis are the most frequently reported tick-borne diseases in Rhode Island.

In addition, in recent years there has been an increase in the number of cases of Powassan virus in the Northeast, including the identification of Rhode Island’s first case in 2016.

The ticks that carry these diseases are endemic to the northeastern and upper midwestern United States.  The greatest risk of being bitten exists in the spring, summer, and fall.

However, ticks may also be out searching for a host during the winter, any time temperatures are above freezing.

Diagnosis & Treatment

Your healthcare provider will assess your symptoms and discuss whether you have been exposed to a potential tick habitat. Laboratory tests can be ordered to determine if there is an organism present in your blood or if your blood contains antibodies to an organism.

Most of the tick-borne diseases are treated with antibiotics. Your healthcare provider will determine the appropriate medication and duration of treatment that is right for your condition.

What You Should Do

Avoid wooded and brushy areas with high grass and leaf litter.

Walk in the center of trails.

Repel Ticks with DEET or Permethrin

Use repellents that contain 20 to 30% DEET (N, N-diethyl-m-toluamide) on exposed skin and clothing for protection that lasts up to several hours. Always follow product instructions. Parents should apply this product to their children, avoiding hands, eyes, and mouth.

Use products that contain permethrin on clothing. Treat clothing and gear, such as boots, pants, socks and tents with products containing 0.5% permethrin. It remains protective through several washings. Pre-treated clothing is available and may provide longer-lasting protection.

Other repellents registered by the Environmental Protection Agency (EPA) may be found at Insect Repellents: Use and Effectiveness.

Find and Remove Ticks from Your Body

Find Ticks

Bathe or shower as soon as possible after coming indoors (preferably within 2 hours) to wash off and more easily find ticks that are crawling on you.

Conduct a full-body tick check using a hand-held or full-length mirror to view all parts of your body upon return from tick-infested areas.

Parents should check their children for ticks under the arms, in and around the ears, inside the belly button, behind the knees, between the legs, around the waist, and especially in their hair.

Examine gear and pets. Ticks can ride into the home on clothing and pets, then attach to a person later, so carefully examine pets, coats, and day packs.

Tumble dry clothes in a dryer on high heat for 10 minutes to kill ticks on dry clothing after you come indoors.

If the clothes are damp, additional time may be needed.

If the clothes require washing first, hot water is recommended. Cold and medium temperature water will not kill ticks effectively.

If the clothes cannot be washed in hot water, tumble dry on low heat for 90 minutes or high heat for 60 minutes. The clothes should be warm and completely dry.

Remove Ticks

If tweezers are not available, use fingers shielded with tissue paper or rubber gloves. Do not handle with bare hands.

Be careful not to squeeze, crush or puncture the body of the tick which may contain infectious fluids.
After removing the tick, thoroughly disinfect the bite site and wash hands. See or call a physician if there is concern about incomplete tick removal.

It is important that a tick be removed as soon as it is discovered. Check after every two or three hours of outdoor activity for ticks attached to clothing or skin.
