Lyme Disease in Kids: Causes, Symptoms & Treatment

Lyme Disease in Children – Causes, Symptoms and Treatment

The bites from black-legged or deer ticks are known to lead to Lyme disease. These are not visible to the naked eye, and immature ticks are often the size of poppy seeds. Adult ticks look like the size of sesame seeds.

What Is Lyme Disease and How Common Is It?

Lyme disease is very common in the United States, being one of the leading tick diseases there. It’s an infectious illness caused by black-legged or deer ticks. Typically, people who are bitten by these ticks don’t feel the bite and have no memory of it. The infection gets passed on when the tick sits on you for 24 to 48 hours and bites. Those who live in woody areas are more prone to tick bites, and thus, this disease.

Causes of Lyme Disease

Lyme disease in toddlers, infants, and adults are caused by various factors. Here are the common ones below:

1. Borrelia Burgdorferi

The strains of the bacteria Borrelia Burgodorferi are known to lead to Lyme disease in humans. These are transmitted through tick bites and are spread by nymphs.

2. Through a Host

The development of a tick happens in three stages – larval, nymph, and adult. When a tick is in its nymph or larval stages, it feeds off the bacteria from livestock and birds. It then transfers these bacteria to humans during upcoming feeding cycles. Small animals can transmit the bacteria responsible for causing Lyme disease on to the ticks and some examples include the grey squirrel in California and Western Fence Lizards.

3. Ixodes Pacificus

The Ixodes Pacificus or the Western Blacklegged Tick is found in woody areas and is known very well for spreading Lyme Disease.

4. Borrelia Afezilii And Borrelia Garinii

These are cork-screw-like bacteria that are known to spread Lyme disease in Europe and Asia. These transmit spirochaete infections.

5. Parks, Grassy, and Woody Areas

Any ticks located in regions like parks, grassy areas, and woody regions are famous for causing Lyme disease. They secrete an anaesthetic by sitting on you, causing you not to feel any pain during bites.

6. Other Carriers

If the eggs of a tick hatch onto the fur of your pet or the bacteria infects other animals, you may acquire Lyme disease from them as they become disease carriers essentially.

Lyme Disease Symptoms in Children

Lyme disease symptoms are tricky because they are often misinterpreted for something else. Signs such as behavioural changes, lack of appetite, or decreasing attention span are sometimes thought of by parents as a temporary phase, when in reality, it’s Lyme disease behind them. In general, the disease goes through three stages and these have their characteristic symptoms which are listed below.

1. Stage 1 Symptoms

Stage 1 is the early localized stage. Its symptoms are

  • “Bull’s-eye” rash which is marked by a dominant central spot
  • Rashes that look like bruises
  • Any rashes which are solid-red or have redness around the edges

2. Stage 2 Symptoms

Stage 2 is the early disseminated stage and occurs many weeks after the day of the tick bite. It is characterized by symptoms which are flu-like such as:

  • Blurry vision
  • Chills
  • Fever
  • Swelling of the lymph nodes
  • Tiredness
  • Aching muscles
  • Headaches
  • Rashes may also appear in different areas besides the site of the tick bite

3. Stage 3 Symptoms

Stage 3 is known as the late disseminated stage and occurs months and years after the tick bite. Symptoms of this stage are:

  • Changes in the rhythm of the heartbeat
  • Difficulty focusing mentally
  • Brain fog
  • Brain disorders like encephalopathy which lead to changes in mood and memory
  • Sleep pattern disturbances
  • Difficulty talking to people or listening to conversations
  • Numb feeling in the arms, legs, and feet
  • Headaches which increase in severity

Also, make sure to watch out other symptoms of Lyme disease in babies and kids by taking note of behavioural changes, poor cognition, sensitivity to light, and night sweats. Achy, stiff and swollen joints are another symptom which makes parents often mistake Lyme disease for arthritis and other conditions, so beware of that.

Diagnosis of Lyme Disease

There two ways Lyme disease in infants and children are diagnosed which are listed below.

  • Visual Inspection by a Medical Professional – This involves looking for the bulls-eye rash and any spots other than the area where the tick has bitten
  • Blood Tests – In 20-25% cases, the rashes may not be visible. This is where the doctor may do a blood test and analyze the sample for the presence of Borrelia bacteria and antibodies in the body.

How Lyme Disease Is Treated in Children?

Lyme disease in toddlers treatment is done usually with a course of antibiotics. However, treatment will depend on the following factors:

  • Whether the child plays outdoors in any tick-infected areas or woody regions
  • Blood test results
  • Any other tests that say positive for spirochetes
  • Any symptoms that exhibit ones of tick bites

Ways to Prevent Lyme Disease in Kids

Here are some different ways to prevent Lyme disease and safeguard your kids from it.

1. Change the Clothing

Don’t let your child wear sleeves or short trousers and shirts. Wear full-sleeved and long clothing when going out to woody areas.

2. Apply Repellents With DEET

Use children’s insect repellents which are known to have 10 to 30%  DEET.

3. Shower After Coming Home

When your child comes back home from outdoors, tell her to shower immediately and not delay.

4.Do Not Visit Tick-prone Areas

This is a no-brainer, but don’t let your child play in areas crawling with ticks.

5.Tuck the Hair Into a Cap

This is to protect the scalp and prevent ticks from crawling up your child’s hair. Ticks can’t jump from above though.

6. Avoid Contact With Anyone Having Lyme Disease

This also includes non-humans like pets and other animals.

7. Get a Medical Diagnosis

If you notice any behavioural, emotional, or physical changes without any rashes developing, get a blood test or medical diagnosis done for early care and prevention.

How to Remove Tick From Your Child’s Body?

Here’s how you remove the tick from your child’s body.

  • Use a pair of tweezers to remove the tick from your child’s body.
  • Don’t twist or jerk when pulling since this won’t remove the tick well.
  • Pluck near the tick’s head or mouth when pulling until it lets go of your child’s skin.
  • Soak a cotton ball for 30 seconds and warm water and apply to your child’s skin, letting it sit. Remove that and the tick will come off.

When to Visit the Doctor?

You should take your child to the doctor or call one in if you notice any flu-like symptoms, facial paralysis or swollen joints alongside any of the symptoms listed above.


Here’s a key question we’ve answered about Lyme disease that strikes the minds of many readers.

1. Is Lyme Disease Contagious?

No, Lyme disease is not contagious and cannot be transmitted from person to person through oral or sexual contact or blood transfusions.

Lyme disease can become dangerous if the symptoms become long-lasting, which is why it’s imperative that you spot and get them treated early. We hope the information above helped but always consult a medical professional just to be sure.
