Tick Bite

Symptoms

DEFINITION

• A tick (small brown bug) is attached to the skin
• A tick recently was removed from the skin

---

Symptoms

• The bite is painless and doesn't itch; so ticks may go unnoticed for a few days.
• After feeding on blood, ticks become quite swollen and easy to see.
• Ticks eventually fall off on their own after sucking blood for 3 to 6 days.

Causes

• The wood tick (dog tick) is the size of a watermelon seed and can sometimes transmit Rocky Mountain spotted fever and Colorado tick fever.
• The deer tick is between the size of a poppy seed (pin head) and an apple seed, and can sometimes transmit Lyme disease.

Lyme Disease

• The risk of Lyme disease following a recognized deer tick bite in a high risk area is estimated to be only 1.4%.
• Almost all infections start with a bull's eye rash (erythema migrans) at the site of the tick bite.
• Antibiotics can be given at this time.
• The routine use of antibiotics following tick bites to prevent Lyme disease is not recommended.

HOME CARE ADVICE FOR TICK BITES

Treating Tick Bites

1. Reassurance: Most tick bites are harmless. The spread of disease by ticks is rare.
2. Tick Removal:
   • For wood ticks, use a tweezers and grasp the tick close to the skin (on its head).
   • Pull the wood tick straight upward without twisting or crushing it.
   • Maintain a steady pressure until it releases its grip.
   • If tweezers aren't available, use fingers, a loop of thread around the jaws, or a needle between the jaws for traction.
   • Tiny deer ticks need to be scraped off with a finger nail or credit card edge.
   • Note: covering the tick with petroleum jelly, nail polish, or rubbing alcohol doesn't work. Neither does touching the tick with a hot or cold object.
3. Tick's Head: If the wood tick's head breaks off in the skin, remove it.
   • Clean the skin with rubbing alcohol.
   • Use a sterile needle to uncover the head and lift it out.
   • If a small piece of the head remains, the skin will eventually shed it.
   • If most of the head is left, call your doctor.
4. Antibiotic Ointment: Wash the wound and your hands with soap and water after removal to prevent catching any tick disease. Apply antibiotic ointment to the bite once.
5. Expected Course: Tick bites normally don't itch or hurt. That's why they often go unnoticed.
6. Call Your Doctor If:
   • You can't remove the tick or the tick's head
   • Fever or rash in the next 2 weeks
   • Bite begins to look infected
   • Your child becomes worse

Preventing Tick Bites

1. Prevention:
   • When hiking in tick-infested areas, wear long clothing and tuck the ends of pants into socks. Apply an insect repellent to shoes and socks.
   • Permethrin products applied to clothing are more effective than DEET products against ticks.
2. Tick Repellent for Skin - DEET:
   • DEET is an effective tick repellent.
   • Use 30% DEET for children and adolescents (AAP recommendation 2003) (30% DEET protects for 6 hours)
3. Tick Repellent for Clothing - Permethrin:
   • Permethrin-containing products (eg, Duranon, Permanone, and Congo Creek Tick Spray) are highly effective tick repellents.
   • An advantage over using DEET is that they are applied to and left on clothing instead of skin. Apply it to clothes, especially pants cuffs, socks and shoes. You can also put it on other outdoor items (mosquito screen, sleeping bags).
   • Do not apply Permethrin to skin (Reason: it's rapidly degraded on contact with skin)
     

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.

Photo Example

Wood Tick in Scalp

This photos shows an engorged (full with blood) wood tick hiding in the hair on the back of the head.

Adult Deer Tick

This adult Deer tick is about the size of an apple seed. The tick is flat and has not yet begun feeding.

Deer Tick (Black-Legged Tick)  

The Deer Tick (black-legged tick) is between the size of a poppy seed (pin head) and an apple seed.

The deer tick is found on a wide rage of hosts including mammals, birds and reptiles.

This tick can transmit Lyme disease to humans and animals during feeding; this occurs when the the tick insert its mouth parts into the skin of a host and slowly ingests the host's blood.

The Wood Tick (or dog tick) is the size of a watermelon seed and can sometimes transmit Rocky Mountain spotted fever and Colorado tick fever.

First Aid - Removing a Tick

Wood Tick Removal:

• Use a pair of tweezers and grasp the wood tick close to the skin (on its head). See image.
• Pull the wood tick straight upward without twisting or crushing it. Maintain a steady pressure until it releases its grip.
• If tweezers aren't available, use fingers, a loop of thread around the jaws, or a needle between the jaws for traction.

Tiny Deer Tick Removal:

• Needs to be scraped off with a knife blade or credit card edge.
• Place tick in a sealed container (e.g., glass jar, zip lock plastic bag), in case your doctor wants to see it.

Note: Covering the tick with petroleum jelly, nail polish or rubbing alcohol doesn't work. Neither does touching the tick with a hot (like a match) or cold object.

Erythema Migrans Rash

The majority of cases of Lyme disease start with a bull's eye rash ("erythema chronicum migrans") at the site of the tick bite. The rash can occur days to weeks (typically 7-10 days) after a tick bite.

Treatment with antibiotics is indicated if this rash appears.

It is thought that Lyme Disease can be prevented if the tick is removed within 24 hours of attachment.
