What is Lyme disease?

Lyme Disease Symptoms
Stage 1 early localized disease with a red rash with "bullseye" appearance occurring at or near the site of the tick bite.

Lyme disease is a multisystem illness caused by infection with the microorganism, Borrelia burgdorferi, and the body’s immune response to its infection. The illness is transmitted from tick bites when the tick regurgitates the microorganism. 

Thus, Lyme disease is known as a “vector-borne disease.” Because the ticks are extremely small and their bites are painless, the biting event very often goes unnoticed.

How long does it take to show signs of Lyme disease?

The signs and symptoms of Lyme disease usually appear one to 30 days after a tick bite, but most commonly between seven and 14 days. The first sign is usually a skin rash and flu-like symptoms.

What happens if you go untreated for Lyme disease?

If untreated, Lyme disease can progress to chronic Lyme disease or stage 3 of Lyme disease. Stage 3 Lyme disease occurs months to years after the initial infection or a period of latency. Most patients presenting with the late disease do not have erythema migrans because the rash urges the patient to seek treatment earlier.

What are the signs and symptoms of Lyme disease by stages?

There are three stages of Lyme disease, which are outlined below. 

Stage 1 Early Localized Disease

  • Occurs one to 30 days after a tick bite
  • Erythema migrans
    • characteristic skin rash of Lyme disease 
    • migrating red rash with “bullseye” appearance occurring at or near the site of the tick bite
    • asymptomatic or itches or burns
    • develops around seven days after the tick bite
    • rash expands over a matter of days 
    • an untreated rash may persist for two to three weeks
  • Approximately half of the early disease patients have flu-like symptoms, which may resolve spontaneously

Stage 2 Early Disseminated Disease

Stage 3 Late Disease

Stage 3 Lyme disease occurs months to years after the initial infection or a period of latency. Most patients presenting with the late disease do not have erythema migrans because the rash urges the patient to seek treatment earlier.

Symptoms of Stage 3 Lyme Disease may include the following:

  • Skin manifestation:
    • Acrodermatitis chronica atrophicans: found almost exclusively in patients of European descent. It commonly affects older women with bluish-red discoloration on the back of the hands, feet, knees, and elbows.
  • Lyme arthritis:
    • typically involves one or a few large joints (knee is involved in 90% of cases).
    • severe inflammation and joint pain
  • Nervous system abnormalities:
    • encephalopathy 
    • encephalomyelitis (inflammation of the brain)
    • neuropathy nerve paralysis
    • acute spinal disk disease. 
    • hemiparesis (weakness of one side of the body)
    • ataxia (loss of muscle coordination)
    • seizures
    • bladder dysfunction (loss of urinary control)
    • hearing loss
    • myelitis (inflammation of the spinal cord)
    • paraparesis (paralysis of lower limbs)
    • quadriparesis (paralysis of all limbs)

QUESTION

The term arthritis refers to stiffness in the joints. See Answer

What is the treatment of Lyme disease?

Lyme disease is commonly treated in the following ways:

  • Treatment with oral and/or intravenous antibiotics to combat infection and medications to provide symptom relief.
  • Removal of attached ticks.

How can I prevent Lyme disease?

Tips to prevent Lyme disease include:

  • Personal and environmental measures to avoid ticks, mice, and other insects 
  • Removal of attached ticks from self, children, and pets
  • Professional management of tick infestation at home

What is the prognosis of Lyme disease?

Prognosis is excellent and most patients recover completely, especially if treated early with appropriate antibiotics. Sometimes a recurrent infection can occur with certain strains, but Lyme disease can be managed well with medication. Co-infection by other organisms transmitted by the same tick bite can occur.
