Lyme Disease: Early Symptoms, Causes, Risks & Treatment

Lyme is a disease that starts quietly with a small bite that most people fail to notice, but it progresses silently into a complex condition that can lead to significant damage if it goes undetected. While it is common in the United States, it is essential to understand how it spreads, how to recognise early symptoms, and when to seek medical help to prevent long-term complications. 

What Is Lyme Disease? 

Lyme disease, or Lyme borreliosis, is a bacterial infection that can affect many systems of the body, including the skin, joints, heart and nervous system. Early stages of this disease causes rash or flu-like symptoms, while later stages may lead to arthritis and nerve-related problems

What are the causes of Lyme disease?

The disease is caused by members of the phylum Borrelia, Spirochaetes. The spiral-shaped bacteria, B. burgdorferi, are common in North America. These ticks are small as nymphs, often the size of a poppy seed, so they are easy to miss.

1. In the United States, the blacklegged tick is the main vector for the disease in the Northeast, mid-Atlantic and upper Midwest.
2. The western blacklegged tick, Ixodes pacificus, spreads the disease along the Pacific Coast.

How Common Is Lyme Disease, And Who Is The Most Vulnerable?

In the US, there is a broadband stretching across the northeastern states, through the mid-Atlantic and into the upper Midwest, with states such as the following reporting the highest share of cases.

• Pennsylvania
• New Jersey
• New York

People who spend time outdoors in forest-like areas, children and adults with outdoor occupations or hobbies are at high risk of getting Lyme due to tick bites

What Are Tick Bite Risks And How Can You Be Exposed To Them?

Public health agencies like the Centres for Disease Control and Prevention (CDC) in the United States say that a tick needs to be attached to you for 24 hours before Lyme can be transmitted. If you successfully remove it within 24 hours, you can reduce the chances of getting the disease.

Sometimes your pets, like dogs and cats, can pick up ticks while outdoors and then bring them indoors, where the ticks may drop off and later bite humans. You should follow regular tick-preventative treatments for pets to reduce the risk of getting the disease. 

What Are Some Early Warning Signs Of Lyme Disease?

Symptoms of the disease typically appear within 1 to 4 weeks after an infected tick bites you. However, they can also appear anytime between 3 to 30 days. Early warning signs are:

1. Bull's-eye rash: This is a hallmark sign of Lyme, typically a circular bull's-eye rash that appears at or near the bite mark and expands over days. The centre may be clear or darker, giving a ring-like appearance and a red patch.
2. Flu-like symptoms: Some have reported developing fever, chills, sweats, fatigue, neck stiffness and swollen lymph nodes shortly after the rash develops. These symptoms can resemble a viral infection, which is one of the reasons early signs are ignored.
3. Muscle aches: You might feel muscle or joint aches and chalk it up to stress or overexertion, but it can be a sign of developing Lyme, even if you don't see a rash. It is important to consult your doctor if the aches persist 

Later Symptoms of Lyme Disease

When the disease goes untreated, the bacteria can disseminate through your bloodstream and cause even more severe and sometimes chronic symptoms, such as:

• Neurological: These symptoms may include headaches, neck stiffness and limb pain. There are cognitive problems like brain fog, memory lapses and difficulty concentrating that are also reported by some patients.
• Joint pain: A very common late-stage manifestation of the disease is arthritis, and it typically involves knee or other large joint pain and swelling episodes. This can persist for months. 
• Heart-related symptoms: In extremely rare cases, Lyme bacteria can invade your heart tissue and cause Lyme carditis, which can further lead to irregular heart rhythms, palpitations, chest discomfort or even shortness of breath. 

How Do You Get A Diagnosis For Lyme Disease?

Your diagnosis will depend heavily on clinical features, exposure history and sometimes laboratory tests, all of which are necessary because there is no perfect test in the early infection stage. The first step is noticing the bite mark and going to your doctor for confirmation

How does your doctor diagnose Lyme?

Your doctor can begin your diagnosis by examining your rash and taking a travel history to rule out any other reasons for the rash. In the late stage, your doctor will likely suggest laboratory tests to confirm their prognosis. 

In the United States of America, the Centres for Disease Control and Prevention (CDC) suggests two-step blood tests to confirm Lyme. 

• The first test is called the Enzyme-linked immunosorbent assay (ELISA), which is used to test for antibodies against the bacteria. However, your body will take some time to produce antibodies, so this test might not always be accurate.
• The second test is called the second ELISA or Western blot, and there are two options for this test. You can do either another ELISA test or a Western blot test. The blot test looks at how your antibodies react to specific parts of the bacteria.

Challenges you might face during diagnosis

Some patients can go undiagnosed for weeks or even months without access to knowledgeable doctors, being unaware of the diseases and variability in lab tests, leading to increased and sometimes complete development of the later-stage complications.

What Are My Treatment Options After A Diagnosis?

Your treatment plan and length will heavily depend on your diagnosis, the stage and the severity of your illness. 

1. Antibiotics: Most people react to antibiotics that are prescribed by their doctor in the early stages of the disease. Many recover rapidly and completely with this treatment plan. The antibiotics only help, however, if your diagnosis was made early. 
2. Later stage: If the disease has developed and reached the later-stage period, like Lyme arthritis, neurological complications or Lyme carditis, it may require a more extensive plan.
3. Post-treatment Lyme disease (PTLDS): You may still experience the symptoms of the illness even after a standard treatment; this condition is known as PTLDS. While the exact cause of PTLDS is still not fully understood, it appears to involve immune or inflammatory processes rather than an active infection.

How can you take precautions against tick bites?

Lyme begins with a tick bite, so the prevention heavily focuses on reducing exposure to the ticks and ensuring that, if a tick is attached to you, you remove it promptly and properly.

1. You should ensure that you wear light-coloured long pants that are tucked into your socks to minimise exposed skin. Also, stay on cleared paths and avoid brushing through dense undergrowth or passing through tall grassy areas to lower the risk of picking up ticks 
2. Tick repellent sprays or oil of lemon eucalyptus (OLE) can be applied to your clothing and skin. Permethrin-treated clothes can kill ticks that contact the fabric and offer an extra layer of protection.
3. You should always shower within a few hours after coming back from being outdoors and perform a full body check. Pay special attention to your scalp, behind your ears and behind your knees. Parents should also check children and pets since ticks are small and hard to see. 
4. If you have a lawn, keep it mowed; clear your leaf litter and create wood chip or gravel barriers around your lawn area to reduce tick habitats.

How to safely remove a tick?

If, while inspecting, you discover a tick is attached to your skin, safe and proper removal is critical to minimise tissue damage and reduce the chance of leaving the mouthparts of the tick in the skin. 

• Step 1: The first step is to use fine-tipped tweezers and grasp the tick as close to the surface of your skin as possible. 
• Step 2: Then very carefully and steadily pull upwards, apply even pressure and avoid twisting or jerking, as it can cause the mouthparts to break off and be embedded in your skin
• Step 3: Lastly, after you have removed the tick, clean the bite area and your hands with soap and water or an antiseptic. 

Common mistakes to avoid when removing a tick

Do not apply any petroleum jelly, nail polish or hot matches to try to detach the tick, as these things can irritate the tick and increase the risk of salivary reflux or incomplete removal. If parts of the tick are embedded in your skin, then it is better to leave them alone and allow your skin to heal naturally

Conclusion

Lyme disease is a complex but largely preventable tick-borne illness that can range from mild and treatable symptoms in its early stages to more serious late-stage problems like arthritis, neurological and heart complications. 

For people living abroad, frequent travellers, or non-resident Indians (NRIs) who split time between countries like India and Lyme-endemic regions, having reliable health insurance coverage is just as important as understanding the disease itself. Medical treatments overseas can be exorbitant, making a robust financial safety net essential. A comprehensive NRI health insurance plan, such as the Niva Bupa NRI Health Insurance plan, can help you bridge this gap, ensuring access to quality medical care and financial protection no matter where you are.

Frequently Asked Questions

Can you get Lyme disease more than once?

Yes, protective immunity after one episode of the illness is incomplete, so people can contract Lyme again if they are bitten by another infected tick

Is Lyme disease contagious between people?

Lyme is not spread from person to person through casual contact, air, food or water. There is no convincing evidence that Lyme is transmitted through sexual contact or routine social interaction.

Can Lyme disease be cured completely? 

Most people fully recover with the appropriate antibiotic therapy, especially when treatment begins early. However, some may experience lingering symptoms that may take months to resolve. 

Is there a vaccine for Lyme disease? 

A vaccine for Lyme is not currently available.
