Lyme disease

Lyme disease is an illness carried by some ticks and transmitted to people when ticks attached to the skin for an extended period of time.  Lyme disease is diagnosed sometimes based on symptoms and sometimes using a laboratory test.  It is treated with antibiotics.


For a tick to transmit Lyme disease it must attach to a person’s skin and feed for 36-48 hours or longer.  Keep in mind that just because you suspect a tick has been attached for more than 36 hours does not mean that Lyme disease was transmitted or that the tick even carried Lyme disease.  There is no evidence of Lyme disease transmission in any other way than described above.


There are many different possible signs and symptoms of Lyme disease.

  • Early symptoms
    • Bulls-eye Rash (Erythema Migrans) – within 1 month after exposure a rash at the site of the tick bite develops in 70-80% of people.The rash is usually flat, red, looks like a bulls-eye and is not itchy or painful.
    • Other – Some people with Lyme disease also develop fever, headache, joint or muscle aches, fatigue and/or swollen lymph nodes within the first month after exposure
  • Late symptoms
    • If untreated, symptoms of Lyme disease may become more severe


Lyme disease is often diagnosed based on the classic “bulls-eye” rash.  If a patient does not develop a rash and has not had a known tick bite in the past few months a blood test is necessary to determine the diagnosis.  Blood tests immediately after a tick bite or in the absence of symptoms are not helpful in determining if a child has Lyme Disease.


The use of an antibiotic for the prevention of lyme disease after a tick bite is available, but is only effective if the patient meets a specific set of criteria.  Please contact your child’s doctor to discuss this.  


In most cases, Lyme Disease is very easily treated.  The overwhelming majority of stories told about people with long-term symptoms of Lyme Disease or of “chronic Lyme Disease” are actually caused by other entities entirely and not related to Lyme Disease or tick bites,

Takeaway message

The most common tick-borne illness on the East Coast is Lyme Disease. While not all ticks carry  Lyme Disease and not all tick exposures lead to Lyme Disease, it is important to recognize the signs and symptoms of the disease in order to receive proper treatment.
