Lyme Disease is the most common U.S. vector-borne illness and it remains a glaring public health concern in many areas of the world. Transmitted primarily through the bite of infected black-legged ticks, also known as deer ticks, this disease can cause serious health problems if not detected and treated early. With climate change and suburban expansion increasing human exposure to ticks, understanding this disease has never been more important.
What is Lyme Disease?

Lyme Disease is caused by the bacterium Borrelia burgdorferi, and in rare cases, Borrelia mayonii. This infection is generally spread to humans through infected ticks’ bite. Most cases in the U.S. happen in the Mid-Atlantic, Northeast, and upper Midwest, more so during the warmer months when ticks are quite active.
Ticks become infected by feeding on birds or mammals—especially rodents—that harbor the bacteria. Once infected, ticks transmit bacteria to humans through each bite. It usually takes 36 to 48 hours of attachment for the bacterium to be transmitted, making early detection and prompt removal of ticks critical. McKinney pediatrics experts emphasize the importance of tick prevention and awareness, especially during warmer months.
Symptoms of Lyme Disease

The signs and symptoms of Lyme Disease vary depending on the infection level or stage:
1. Early Localized Stage (3–30 days after bite)
The first symptom of infection is often that red rash that is ever expanding, this is called erythema migrans (EM). This rash may resemble a bull's-eye—red in the center and outer edge with a clear ring in between—and occurs in about 70–80% of infected individuals. A McKinney pediatrician can help identify these early signs and provide timely treatment. Other early symptoms may include:
Chills
Headache
Fatigue
Muscle and joint aches
Swollen lymph nodes
2. Early Disseminated Stage (days to weeks after the tick bite)
If untreated, Lyme Disease can spread to other parts of the body. Symptoms at this stage may include:
Additional EM rashes on other parts of the body
Facial palsy (the loss of muscle tone or a droop on one or both sides of the face)
Severe headaches and neck stiffness due to meningitis
Pain and swelling in large joints
Heart palpitations or irregular heartbeat (Lyme carditis)
3. Late Disseminated Stage (months to years after the bite)
When left untreated, Lyme Disease can lead to chronic joint inflammation (Lyme arthritis), neurological problems like numbness, memory issues, or nerve pain, and even persistent fatigue. In rare cases, it can cause severe cognitive impairments and permanent neurological damage.
Diagnosing Lyme Disease

Because many of the symptoms of Lyme Disease mimic those of other illnesses, diagnosis can be tricky. Doctors typically consider a combination of:
Clinical signs such as the EM rash
History of tick exposure
Laboratory testing for antibodies to Borrelia burgdorferi
Two-tiered blood testing is the standard approach:
If positive or equivocal, followed by a Western blot test
However, it's important to note that antibodies may not be detectable in the early stages, so a negative result does not always rule out the disease. Mckinney pediatricians are trained to evaluate symptoms alongside test results to ensure accurate diagnosis and early treatment.
Treatment of Lyme Disease

When caught early, Lyme Disease is usually effectively treated with antibiotics. The most commonly prescribed medications are:
Doxycycline (for adults and children over 8)
Amoxicillin or cefuroxime (for younger children and pregnant women)
The standard treatment duration is 10 to 21 days. Most patients recover completely, especially if treatment begins soon after infection.
For those with late-stage Lyme Disease, longer antibiotic courses may be necessary, particularly for joint or nervous system involvement. However, some individuals may continue to experience symptoms even after treatment—a condition known as Post-Treatment Lyme Disease Syndrome (PTLDS). The cause of PTLDS is not fully understood, and ongoing research is looking at better treatment options for these patients.
Preventing Lyme Disease

Since there's no vaccine currently available for humans, prevention remains the best defense against Lyme Disease. Here are some steps to reduce your risk:
1. Avoid Tick Habitats
Stay on clear, well-traveled trails when hiking
Avoid wooded, brushy, and grassy areas with high leaf litter
Walk in the center of trails
2. Use Tick Repellent
Apply EPA-registered insect repellents containing DEET, picaridin, or IR3535 on skin
Treat clothing and gear with products containing 0.5% permethrin
3. Wear Protective Clothing
Wear long sleeves and pants
Tuck pants into socks or boots
Choose light-colored clothing to spot ticks more easily
4. Check for Ticks
Perform full-body checks after spending time outdoors
Inspect under arms, behind knees, around the ears, and other hidden areas
Check gear and pets as ticks can be carried indoors
5. Prompt Tick Removal
Utilize fine-tipped tweezers unhook the tick as close to the skin’s surface as you can
Pull upward with steady, even pressure
Clean the bitten area using either alcohol or soap and water
Save the tick in a sealed container for possible testing
The Importance of Tick Control

Controlling the tick population in your yard and community can help reduce the risk of Lyme Disease. You can:
Keep lawns mowed and remove leaf litter
Set up tick-safe zones by using gravel or wood chips in between wooded areas and lawns
Use pesticides as a last resort for tick control
Deer are a major host for adult ticks in some regions. Installing deer-resistant fencing and avoiding plants that attract deer may help limit tick presence. At Kidsville Pediatrics, we recommend these preventative measures to help families reduce the risk of tick exposure.
Rising Cases and Climate Change

One reason Lyme Disease is on the rise is due to warmer winters and extended tick seasons caused by climate change. As deer and ticks get into new areas, people in previously unaffected regions started facing risk. In fact, Lyme Disease is now being diagnosed in parts of Canada and the upper South, where it was rare in past decades.
Suburban expansion into forested areas also brings people into closer contact with ticks and their hosts. As a result, awareness and public education campaigns are becoming more critical.
Lyme Disease in Children
Children aged 5–14 are among the most at-risk populations for Lyme Disease, especially those who play outdoors or attend summer camps. Pediatric cases may be more challenging to diagnose since children may not describe symptoms clearly or remember a tick bite. McKinney pediatrics McKinney TX experts are trained to recognize and treat Lyme Disease early, even when symptoms are subtle.
Parents should be vigilant about tick checks after outdoor activities, especially during the spring and summer months. Pediatricians are trained to recognize signs of Lyme Disease early in children and initiate prompt treatment.

Lyme Disease is a serious but preventable condition. Early detection as well as treatment are key to avoiding any long-term complications. While researchers continue to work on vaccines and better treatments, public awareness and prevention remain our strongest tools. If you spend time in tick-prone areas, knowing how to protect yourself and your family is essential.
Stay educated. Stay vigilant. And take Lyme Disease seriously—for your health and the health of your community.
