 It’s Tick Season in Wayland:
Keep Yourself Safe from Ticks and Tick-Borne Illnesses

Ticks are found all around New England, especially in wooded areas like Wayland. Many people will find a tick on themselves, and yet only a small proportion of those will develop a tick-borne illness like Lyme Disease. However, it is best to know the facts about how to avoid ticks, what to do if you find one on you, and what symptoms can indicate that they may have an illness related to a tick bite, and how to maintain your yard to reduce tick habitats.
There are multiple tick-borne Illnesses transmitted in this area. These include Anaplasmosis, Ehlrichiosis, and Babesiosis. Since Lyme Disease is by far the most common, and can be the most subtle, we will concentrate on that. There also have been concerns raised about Powassan virus. However, the same steps to prevent tick bites and immediately remove them serve for all tick-borne illnesses.

Preventing Tick Bites and habitats

 Ticks are found in wooded and bushy areas, near the ground; they cannot jump or fly.
 They are attracted to body heat and carbon dioxide (in the breath we exhale).
 They transfer to a human when one brushes against them.
 Keep your lawn mowed and short. Trim back brush and low hanging branches.
 Remove leaf litter, wood piles, fallen branches, trash and debris; all attract ticks.
 Avoid wooded and brushy areas with high grass and leaf litter.
 Bird feeders should be moved to low traffic areas, seed and suet attracts wildlife that can carry ticks.
 Consider installing a deer fence or use plantings that deer do not like.
 Walk in the center of trails. Keep paths and trails mowed wide.
 Wear long sleeves and pants, and a cap/hat. Pull socks over trousers. Use a lint brush to check for and remove ticks.
 Use repellent that contains 20 percent or more DEET, picaridin, or IR3535 on exposed skin for protection that lasts several hours. DEET products should not be used on infants under 2 months of age.
 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 be       
  protective longer. Helpful information can be found at: .
 Always read the product label carefully of any repellent and follow instructions as per the product label.
 A number of plant-derived products are available for use as repellents. Limited information is available regarding how well these products work as tick repellents and how safe they are.
 Protect pets 12 months a year with a tick product. Use fences to create tick safe zones.

Find and Remove Ticks from Your Body

 Bathe or shower as soon as possible after coming indoors (preferably within two 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.
   o  If the clothes are damp, additional time may be needed.
   o If the clothes require washing first, hot water is recommended. 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.

Removing a Tick

If you find a tick attached to your skin, there's no need to panic. There are several tick removal devices on the market, but a plain set of fine-tipped tweezers will remove a tick quite effectively.

1. Use fine-tipped tweezers to grasp the tick as close to the skin's surface as possible.
2. Pull upward with steady, even pressure. Don't twist or jerk the tick; this can cause the mouth-parts to break off and remain in the skin. If this happens, remove the mouth-parts with tweezers. If you are unable to remove the mouth easily with clean tweezers,      leave it alone and let the skin heal.
3. After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol, an iodine scrub, or soap and water.
4. Dispose of a live tick by submersing it in alcohol, placing it in a sealed bag/container, wrapping it tightly in tape, or flushing it down the toilet. Never crush a tick with your fingers.

Avoid folklore remedies such as "painting" the tick with nail polish or petroleum jelly, or using heat to make the tick detach from the skin. Your goal is to remove the tick as quickly as possible–not waiting for it to detach.

 Lyme Disease is caused by the bacteria Borrelia burgdoferi which is found in small woodland animals like mice, racoons, chipmunks, squirrels, and deer.
 It has the potential to be transmitted to humans through Deer Ticks which have first come into contact with one of the above creatures prior to attaching to a human.
 A tick must be attached to a human host for 48 hours to transmit Lyme Disease to that person.
 Rapid removal of the tick will decrease the risk of transmission of Lyme Disease (and any other Tick-borne Illnesses).
 Deer Ticks are between the size of a poppy seed and a sesame seed when they have not yet fed on a human (i.e. been able to transmit Lyme).
 Engorged Deer Ticks (which have fed on a human and have the potential to transmit disease) are the size of an apple seed.


 In 2014, there were 3830 confirmed cases of Lyme Disease in Massachusetts and 1,770 probable cases.
 The highest rates were in children 5-9 years and those aged 65-74 years
Early Signs and Symptoms of Lyme Disease: (3 to 30 days after tick bite)

 Fever, chills, headache, fatigue, and swollen lymph nodes.
 Arthritis- painful, swollen joints (occurs in approx. 30% of people with Lyme)
 Erythema migrans (EM) rash aka (Bullseye Rash) :
o Occurs in approximately 70 to 80% of infected persons
o Begins at the site of a tick bite after a delay of 3 to 30 days (average is about 7 days)
o Expands gradually over a period of days reaching up to 12 inches or more (30 cm) across
o May feel warm to the touch but is rarely itchy or painful
o Sometimes clears as it enlarges, resulting in a target or “bull’s-eye” appearance
o May appear on any area of the body

Later Signs and Symptoms (days to months after tick bite)

 Severe headaches and neck stiffness (2.8%)
 Additional EM rashes on other areas of the body
 Arthritis with severe joint pain and swelling, particularly the knees and other large joints (30% of patients)
 Facial palsy (loss of muscle tone or droop on one or both sides of the face) (8% of patients)
 Intermittent pain in tendons, muscles, joints, and bones
 Heart palpitations or an irregular heart beat (Lyme carditis) (1% of patients)
 Episodes of dizziness or shortness of breath (1% of patients)
 Inflammation of the brain and spinal cord (2-3% of patients)
 Nerve pain (4-5% of patients)
 Shooting pains, numbness, or tingling in the hands or feet (4-5% of patients)
 Problems with short-term memory

Laboratory Diagnosis

 Determining if a person has Lyme Disease is generally done based on symptoms, with laboratory testing performed only if the diagnosis is not otherwise clear
 Unfortunately, there is not one perfect blood test for Lyme Disease, so physicians may have to perform a stepwise approach to looking for evidence of Lyme Disease with more than one test.
 There are high rates of both false positive (the test says you have Lyme Disease but you really do not) as well as False Negatives (the test says you don’t have it when you really do)
 Therefore, it is important to work alongside your healthcare provider if you feel you may have Lyme Disease


 Antibiotics are standard treatment for Lyme Disease.
 The vast majority of people have their symptoms resolve after taking their prescribed course of antibiotics.
 Generally, for children under 8 years old, the preferred antibiotic is Amoxicillin, though if a child is allergic to penicillins or has more advanced Lyme Disease another antibiotic may be chosen.
 For those aged 8 years and up, generally Doxycycline is the antibiotic of choice, unless a person has an allergy to it or more advanced disease.

Prophylaxis/ Prevention after Tick Exposure

 Prophylaxis is an option in some cases, but certainly not always recommended.
 In general, the risk of antibiotics is greater than the risk of Lyme Disease.
 In children under 8, there is no widely accepted antibiotic that has been shown to prevent Lyme Disease.
 Therefore, it is always best to discuss the issue of prophylactic antibiotic with your own health care provider to determine what may be best for your own scenario.
 If you are going to do this, calling immediately after finding the tick is important, as prophylactic antibiotics are most effective when started shortly after the tick bite is noted.
