Although Lyme disease is a public health concern, extensive publicity has resulted in a degree of anxiety about Lyme disease that is out of proportion to the actual morbidity that it causes.

Lyme Disease Prevention, Diagnosis, and Treatment

Lyme disease is a tick-borne illness caused by the bacteria Borrelia burgdorferi. It can lead to a wide range of symptoms, including fatigue, joint pain, and neurological problems. Early diagnosis is crucial for effective treatment. Diagnosis is typically based on symptoms, medical history, and a blood test to detect antibodies against B. burgdorferi.  Early treatment can help prevent complications and long-term health issues.

Chronic Lyme Disease
Chronic Lyme disease” refers to a nonspecific diagnosis without a consistent definition that has been given to patients with various generic symptoms that could be associated with infection with B. burgdorferi, but are not confirmed to be. Individuals diagnosed, either by a “Lyme literate” physician or by themselves, attribute symptoms such as fatigue and nonspecific pain to chronic Lyme.

We caution patients against seeking providers who use treatment regimens different from the ISDA guidelines and those who use non-standard or experimental Lyme disease tests.

Risk of Contracting Lyme Disease by State

High risk areas, relevant Ixodes tick species are widespread and have been found to be consistently infected with Borrelia burgdorferi.

  • Pennsylvania
  • New Jersey
  • New York
  • Wisconsin
  • Maine
  • New Hampshire
  • Minnesota
  • Maryland
  • Connecticut
  • Virginia
  • Vermont
  • Rhode Island
  • West Virginia
  • Massachusetts
  • Delaware

*Risk is calculated by prevalence/existence of either Ixodes scapularis or Ixodes pacificus ticks, the bacterium (Borrelia burgdorferi spp.), epidemiological data demonstrating ticks are infected, and population size/distribution in areas where people are found.

Moderate risk areas, relevant Ixodes tick species can be found infected with Borrelia burgdorferi, but distribution across the state is less widespread or clustered in specific areas.

  • California
  • Ohio
  • Michigan
  • Illinois
  • North Carolina
  • District of Columbia
  • Iowa
  • Indiana

*Risk is calculated by prevalence/existence of either Ixodes scapularis or Ixodes pacificus ticks, the bacterium (Borrelia burgdorferi spp), epidemiological data demonstrating ticks are infected, and population size/distribution in areas where people are found.

Low risk areas, relevant Ixodes species have been found, but only sparse areas where they have been identified to be carrying Borrelia burgdorferi.

  • Tennessee
  • Kentucky
  • South Carolina
  • North Dakota
  • Washington
  • South Dakota
  • Nebraska
  • Louisiana

*Risk is calculated by prevalence/existence of either Ixodes scapularis or Ixodes pacificus ticks, the bacterium (Borrelia burgdorferi spp), epidemiological data demonstrating ticks are infected, and population size/distribution in areas where people are found.

Very low risk areas, only I. scapularis ticks have been found, and there has been no record of infection with Borrelia burgdoferi identified.

  • Oklahoma
  • Kansas
  • Oregon
  • Florida
  • Alabama
  • Utah
  • Georgia
  • Texas
  • Arkansas
  • Nevada
  • Arizona
  • Missouri
  • Mississippi

*Risk is calculated by prevalence/existence of either Ixodes scapularis or Ixodes pacificus ticks, the bacterium (Borrelia burgdorferi spp), epidemiological data demonstrating ticks are infected, and population size/distribution in areas where people are found.

No risk areas have either Ixodes ticks or Borrelia burgdorferi as resident species

  • Alaska
  • Colorado
  • Hawaii
  • Idaho
  • Montana
  • New Mexico
  • Wyoming

*Risk is calculated by prevalence/existence of either Ixodes scapularis or Ixodes pacificus ticks, the bacterium (Borrelia burgdorferi spp), epidemiological data demonstrating ticks are infected, and population size/distribution in areas where people are found.
