The bite of an infected black-legged tick causes lyme disease. It is a tick-borne illness that is mainly induced by the presence of the bacteria Borrelia burgdorferi.
When people are engaged in outdoor activities, the chances are more to get exposed. Learning about the lyme condition and the areas where people get more exposed to such diseases can help to prevent it.
In case of lyme disease early detection is more crucial to avoid long-term health problems. Fever, exhaustion, and bull’s eye rash are the common indicators of this symptom. Getting informed and taking proactive steps is crucial to improve their health. Let’s deep dive into this blog and understand more on the symptoms, diagnosis, and treatment options of lyme illness.
Tick attachment to the human body:
The tick has to remain attached to the skin for a period of 36-48 hours to be able to transfer the bacteria.
Environmental Risks:
Spending long hours in a woody and grassy area, bushy lands, or forests expands the risk of tick infestation.
Transmission:
When the tick bites the bacteria known as Borrelia burgdorferi transmitted into the blood through the saliva while the tick is feeding.
After engaging in outdoor activities, make sure to check for ticks. If you find the tick and removing it immediately can eliminate the risk of infection.
Signs and Symptoms of Lyme Disease
1. Early Symptoms (3-30 Days After Tick Bite)
Erythema Migrans (EM)
Nearly 70% – 80% of cases, bull’s eye rash (a ring-like red rash) is found at the area of tick bite and it expands over the days.
Flu-like Symptoms
Lyme illness resembles flu-like symptoms that includes fever, headaches, chills, fatigue, enlarged lymph nodes, and muscle soreness or joint pain
2. Later Symptoms (Weeks to Months After Tick Bite)
- Joint Pain and Swelling: Large joints such as knees get affected. It can be painful or swollen that persists for a long time or comes and goes. It is frequent in persons if not treated properly.
- Neurological Issues: When left untreated, people can experience neurological issues like facial palsy (one aspect of the face or both sides being temporarily paralyzed). It also includes headaches, meningitis, hand and feet numbness, and sensations around them.
- Heart diseases: When the illness persists for a long time it can even affect the cardiac functioning. It disrupts the electrical signals in the heart resulting in dizziness, fainting, or an irregular heartbeat. Even though this symptom is not common, it is a serious condition as it needs immediate medical intervention.
It is highly advised that they contact a healthcare professional and know the signs of Lyme conditions.
What Causes Lyme Disease?
Geographical Location:
States such as the northeastern region and the upper midwestern region in the United States have a high degree of tick density. These areas where people will have a higher chance of getting infected.
Outdoor Activities:
Increasing chances of being exposed by hiking, camping, and gardening.
Tick Behavior:
The nymphal stage or larval stages of a tick are the worst in transmitting the disease as they are so tiny that they are hard to notice.
Lack of Prevention:
Since there are no specific clothes that protect or tick sprays to prevent lyme, they are more likely to get bitten.
How is Lyme Disease Diagnosed?
Medical History
The physician inquires about the health history and the developed symptoms.
Physical Exam
Examine physically for the bull’s-eye rash or any other signs of Lyme condition.
Laboratory Tests
ELISA Test
Assesses the presence of antibodies to Borrelia burgdorferi.
Western Blot
The confirmatory test for a positive ELISA test.
In its early stages, blood tests may not detect the disease. So diagnosis often depends on symptom patterns and exposure history.
Treatment Options and Prevention
Pharmacological Treatment
Antibiotics
At an early stage of disease physicians give antibiotics. A regular 10-21 day course is advised.
Pain Management
Over-the-counter medications and anti-inflammatories can treat joint pain and swelling.
Non- Pharmacological Treatment
Avoid Tick Habitats
Avoid going to wooded or grassy areas where ticks are highly populated and especially during the seasonal months.
Wear Protective Clothing
Wear fully covered clothes like pants, long sleeves, and closed shoes.
Use Tick Repellents
Use EPA-approved tick repellents. It must be applied on clothes and any exposed skin if going into areas where ticks are highly populated.
Conduct Tick Checks
If you are in a tick populated area ensure that you check yourself and your clothes completely once you are from outdoors. If you have pets that have ‘played’ in the outdoors make sure it has not been affected by the tick bite.
Maintain Your Yard
Keep your yard clean, remove the leaf debris and trimmings, and set aside areas free of ticks in your yard.
