What is Lyme Disease?

According to the Centers for Disease Control and Prevention (CDC), Lyme is transmitted to humans through the bite of infected blacklegged ticks.
Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans.
If left untreated, infection can spread to joints, the heart, and the nervous system.

Symptoms of Lyme disease depend on the stage of the condition.

(1) Stage 1

The early symptoms of Lyme disease begin to appear within 3 to 30 days after a tick bite.
In this stage, the disease has a limited set of symptoms that includes rash, fever, headache, muscle aches etc. and hence is called early localised disease.

(2) Stage 2

Stage 2 is often more serious and widespread. It is called early disseminated disease.
Symptoms include more rashes on other parts of the body, neck pain or stiffness, muscle weakness on one or both sides of the face etc.

(3) Stage 3

In the United States, the most common condition of this stage is arthritis in large joints, particularly the knees.
Pain, swelling or stiffness may last for a long time. Or the symptoms may come and go.
Stage 3 symptoms usually begin 2 to 12 months after a tick bite.
