Lyme disease is a bacterial infection caused by Borrelia burgdorferi, which is spread by blacklegged ticks. The disease can cause a variety of symptoms, including fatigue, body aches, and difficulty thinking. While most people recover completely with a 2- to 4-week course of oral antibiotics, some individuals may experience prolonged symptoms, known as Post-Treatment Lyme Disease Syndrome (PTLDS). These extended symptoms can include muscle soreness, joint pain, and Bell's palsy, which is paralysis of the facial muscles. Understanding the prolonged effects of Lyme disease is an ongoing area of research, as the specific causes of PTLDS are currently unknown.

What You'll Learn
Lyme disease is caused by the bacteria Borrelia burgdorferi
Lyme disease is a bacterial infection caused by the spirochete Borrelia burgdorferi, which is transmitted to humans through the bite of infected blacklegged ticks. The Borrelia genus of bacteria is a group of gram-negative bacteria that are spiral-shaped and surrounded by flagella and peptidoglycan. The Lyme-related Borrelia species are collectively referred to as Borrelia burgdorferi sensu lato and exhibit significant genetic diversity. This complex species includes 20 accepted and three proposed genospecies, eight of which are known to cause Lyme disease. These include B. mayonii and B. burgdorferi sensu stricto, found in North America and Europe, and B. afzelii, B. garinii, B. spielmanii, and B. lusitaniae, found in Eurasia.
The Borrelia burgdorferi bacteria are transmitted to humans primarily during the nymph stage of the tick's life cycle, when the ticks are most active and feed on mammalian hosts. Tick bites often go unnoticed due to the small size of the ticks in this stage and their secretions, which prevent the host from feeling any itch or pain from the bite. The bacteria migrate from the tick's midgut to its salivary glands, where it binds to Salp15, a tick salivary protein with immunosuppressive properties that enhance infection. Successful infection of a mammalian host depends on the bacterial expression of this protein.
The most common sign of Lyme disease infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week after the bite. This rash is typically neither itchy nor painful, and approximately 70-80% of infected people develop it. Other early symptoms of Lyme disease may include fever, headaches, tiredness, muscle and joint aches, swollen lymph nodes, and chills. If left untreated, more severe symptoms may develop, including loss of facial movement, severe headaches with neck stiffness, heart palpitations, and arthritis with severe joint pain and swelling.
While most people recover completely from Lyme disease with a 2- to 4-week course of oral antibiotics, some individuals experience prolonged symptoms such as fatigue, body aches, and difficulty thinking. The condition where patients experience prolonged symptoms is known as Post-Treatment Lyme Disease Syndrome (PTLDS), and its cause is currently unknown. Studies have shown that extended treatment with antibiotics is generally ineffective for curing prolonged symptoms and may even lead to serious complications such as sepsis or colitis. Therefore, it is important for individuals experiencing prolonged symptoms to work with their healthcare providers to evaluate all possible causes and determine the best treatment approach.

It is spread by infected blacklegged or deer ticks
Lyme disease is caused by a type of bacteria called Borrelia burgdorferi, which can be transmitted through the bite of an infected black-legged tick. These ticks are also called deer ticks and are primarily found in the northeastern, mid-Atlantic, and north-central United States. They live in forested or brushy areas and perch on the tips of grasses or shrubs, climbing onto people or animals that brush by. Black-legged ticks pick up the bacteria after feeding on infected rodents, such as mice and deer, and then transmit it to humans through their bites. It's important to note that ticks usually need to remain attached for at least 24 to 36 hours to transmit the infection, and prompt tick removal can prevent transmission.
While Lyme disease is the most commonly reported tick-borne disease in the United States, it is rare in Washington State, where the ticks that spread the disease are found primarily in western Washington and the eastern slopes of the Cascades. In North America, most cases of Lyme disease occur between May and August.
The symptoms of Lyme disease can vary, but often include a characteristic "bull's-eye" or target-shaped rash, fever, headache, and muscle or joint pain. Some people may not exhibit any symptoms, or they may mistake them for the flu. If left untreated, later symptoms can include recurring joint pain and swelling, heart disease, and nervous system disorders.
It's important to note that Lyme disease cannot be spread through touching, kissing, or sexual contact. While dogs and cats can get Lyme disease, there is no evidence that they can spread it directly to their owners. However, pets can bring infected ticks into the home or yard, and hunting and dressing game animals may also bring people into close contact with infected ticks.

Symptoms include fatigue, muscle and joint pain, and rash
Lyme disease is caused by the bacteria Borrelia burgdorferi and is spread by blacklegged ticks. The most common symptom is the erythema migrans (EM) rash, which occurs in around 70-80% of cases. However, fatigue, muscle and joint pain, and rash are also common symptoms of Lyme disease.
The EM rash usually develops at the site of the bite within days to weeks. It often appears as a solid red or pink rash that starts small and expands to over 2 inches in size. Sometimes, there can be multiple rashes that appear as "satellite" rashes. The rash can also present as a “target” or “bull's eye” pattern, but this is less common, occurring in only about 10-20% of cases.
In addition to the rash, Lyme disease can cause a range of other symptoms, including fatigue, muscle and joint pain, headache, fever, and chills. These symptoms can occur with or without the presence of a rash. Fatigue is a particularly common symptom, with patients often reporting extreme tiredness.
Musculoskeletal involvement, particularly arthritis, is also a common feature of Lyme disease. Patients may experience migratory musculoskeletal pain in joints, tendons, muscles, or bones. This pain can last for hours or days in a given location before moving to a new area. If left untreated, Lyme disease can lead to chronic monoarticular or oligoarticular arthritis, primarily affecting large joints such as the knees.

Treatment is with antibiotics, but symptoms can persist
Lyme disease is caused by the bacteria Borrelia burgdorferi and is spread by blacklegged ticks. The disease can cause joint pain and damage to nerves all over the body, including the skin, muscles, and organs (polyneuropathy). Antibiotics are the standard treatment for Lyme disease, typically doxycycline or amoxicillin. The length of treatment depends on the stage of infection, with most people recovering completely after a 2- to 4-week course of oral antibiotics.
However, it is important to note that even with early diagnosis and prompt treatment, some patients may still experience ongoing or recurrent symptoms related to Lyme disease. This condition is known as Post-Treatment Lyme Disease Syndrome (PTLDS) or, alternatively, Post-Treatment Lyme Disease (PTLD). Symptoms can include severe fatigue, body pain, and cognitive challenges, and they can persist for six months or more following the end of treatment. Approximately 5-15% of patients experience these prolonged symptoms, which can have devastating effects on a person's life.
While additional antibiotics may be prescribed, studies have shown that extended treatment with antibiotics is typically no more effective than a placebo in curing prolonged symptoms. Furthermore, long-term antibiotic use carries the risk of serious, even life-threatening, complications such as sepsis or colitis. As such, it is important for patients experiencing prolonged symptoms to work closely with their healthcare providers to evaluate all possible causes and develop an appropriate treatment plan.
Currently, there are no FDA-approved treatments specifically for the persistent symptoms of Lyme disease. Treatment approaches must be individualized, addressing the specific findings, symptoms, and circumstances of each patient. While most patients will eventually recover, it can take many months to feel completely well.

Post-Treatment Lyme Disease Syndrome (PTLDS) can have devastating effects
Lyme disease is caused by the bacteria Borrelia burgdorferi and is spread by the bite of an infected blacklegged tick. The symptoms of Lyme disease include fever, chills, headache, fatigue, muscle and joint aches, swollen lymph nodes, and swollen knees. If left untreated, Lyme disease can cause severe joint pain and swelling, irregular heartbeat, and facial palsy.
Even after treatment with antibiotics, some people with Lyme disease experience prolonged symptoms such as fatigue, body aches, difficulty thinking, pain, insomnia, and depression. This condition is known as Post-Treatment Lyme Disease Syndrome (PTLDS) and can have devastating effects on a person's life. The cause of PTLDS is currently unknown, and there are no universal guidelines for its diagnosis and treatment. This lack of understanding and standardized care can leave patients suffering and searching for answers, with their daily activities and quality of life significantly impacted.
PTLDS patients often experience impaired work, social, or family interactions, with diminished well-being and health-related quality of life comparable to those suffering from other chronic illnesses. The prolonged symptoms of PTLDS can be challenging and frustrating for both patients and healthcare providers, as the cause of these symptoms is not always clear and may be due to various factors. It is important to work closely with a healthcare provider to evaluate all possible causes and develop an appropriate treatment plan.
While the exact mechanism underlying PTLDS is not yet fully understood, studies have reported a range of risk factors, including delayed diagnosis and exposure to inappropriate antibiotics and steroids prior to receiving the correct treatment. Researchers are actively investigating this condition and working to identify comprehensive treatment strategies for PTLDS patients. However, it is important to note that extended treatment with antibiotics has not been shown to be effective for curing prolonged symptoms, and long-term antibiotic use can have serious, even deadly, complications.
