Lyme Disease Cases Soar in U.S.

By Pat Anson, PNN Editor

Diagnoses of Lyme disease in the United States have soared over the past 15 years, primarily in rural areas in the Northeast, according to a new analysis of private insurance claims by FAIR Health, a nonprofit that tracks healthcare costs and insurance trends.   

Lyme disease is a bacterial illness spread by ticks. Left untreated, it can lead to chronic fatigue, muscle and joint pain, cognitive issues and other long-term symptoms that are often misdiagnosed as fibromyalgia, neuropathy or autoimmune disorders.

In its analysis of over 36 billion insurance claims from 2007 to 2021, FAIR Health said that claims with a Lyme disease diagnosis rose 357 percent in rural areas and 65 percent in urban areas. The highest rates of Lyme disease were in New Jersey, Vermont, Maine, Rhode Island and Connecticut.

“Lyme disease remains a growing public health concern. FAIR Health will continue to use its repository of claims data to provide actionable and relevant insights to healthcare stakeholders seeking to better understand the ongoing rise of Lyme disease cases,” FAIR Health President Robin Gelburd said in a press release.

The FAIR Health study found that malaise, fatigue and soft-tissue-related symptoms were significantly more common in Lyme patients than in the overall patient population.

Other early symptoms of Lyme disease include fever, chills, headache, and swollen lymph nodes. A delayed rash often appears at the site of the tick bite. The rash grows in size and sometimes resembles a bulls-eye.

Although Lyme disease is treatable with antibiotics, some patients develop long-term symptoms known as Lyme disease syndrome or chronic Lyme disease.

About 30,000 Lyme cases are reported annually by state health departments. The CDC estimates the actual number of cases is probably much higher and that about 300,000 Americans may become infected every year.

Most reported cases of Lyme disease occur in the Northeast, mid-Atlantic and upper Midwest, especially during the summer months when more people spend time outdoors. Recent studies show Lyme is spreading to neighboring states and is no longer just a seasonal disease, possibly due to the effects of climate change.

Insurance Claims Climb for Lyme Disease

Private insurance claims with a diagnosis of Lyme disease have soared in the U.S. over the past decade, according to a new report by FAIR Health, a nonprofit that tracks healthcare costs and insurance trends.

Lyme disease is a bacterial illness spread by ticks. It can also lead to other chronic pain conditions such as joint and back pain, chronic fatigue, fibromyalgia and neuropathy.

Fair Health analyzed a database of 23 billion private insurance claims from 2007 to 2016, and found that claims with a diagnosis of Lyme disease increased by 185 percent in rural areas and 40 percent in urban areas.

A recent CDC study also found the number of Lyme disease cases increasing, with nearly 40,000 confirmed and probable cases in 2015.

"Lyme disease is growing as a public health concern,” said FAIR Health President Robin Gelburd

Although Lyme disease historically has been concentrated in the Northeast and upper Midwest, the FAIR Health study suggests that it is spreading geographically. In 2007, insurance claims with diagnoses of Lyme disease were highest in New Jersey, Rhode Island, Connecticut, Massachusetts and New York.

By 2016, the top states were Rhode Island, New Jersey, Connecticut, North Carolina and New York -- with the emergence of North Carolina suggesting significant expansion to a new region.

Summer is the peak season for Lyme disease, with insurance claims more common in rural than in urban settings, according to the FAIR Health report. In the winter and early spring (December through April), claims involving Lyme disease were reported more often in urban than rural settings.

Age is also a differing factor in rural and urban environments. In rural settings, claims with Lyme disease diagnoses were more common for middle-aged and older people. Patients aged 41 years and older accounted for nearly two-thirds of the rural diagnoses. In urban populations, younger individuals with Lyme disease accounted for a higher percentage of claims.

Lyme disease is usually treated with antibiotics, but some patients experience complications that lead to Lyme disease syndrome (PTLDS), with long-term symptoms such as fatigue, muscle and joint pain and cognitive issues. Autoimmune diseases have also been associated with chronic Lyme disease.

Left untreated, Lyme disease can lead to serious chronic conditions, as Sarah Elizabeth Hirschle shared with us recently.

For patients with a Lyme disease diagnosis, FAIR Health reported the most common subsequent diagnoses were:

• Joint pain (dorsalgia, low back pain, hip and knee pain)
• Chronic fatigue  
• Soft tissue disorders (myalgia, neuralgia, fibromyalgia)
• Hypothyroidism

lyme disease rash

Early symptoms of Lyme disease include fever, chills, headaches, fatigue, muscle and joint aches, and swollen lymph nodes. A delayed rash often appears at the site of the tick bite. The rash grows in size and sometimes resembles a bulls-eye.
