Question

At which stage of Lyme disease, erosion of cartilage and bone occurs?

• A. Stage 1
• B. Stage 2
• C. Stage 3
• D. Stage 4

Answer 1

The correct option is C Stage 3

Lyme disease is caused by the bacterium Borrelia burgdorferi. It is transmitted to humans through the bite of infected black-legged ticks. It is characterized by 3 stages.

Stage 1 is characterized by the skin rash called erythema migrans.

Stage 2 is characterized by fever, headache, fatigue and chills.

Stage 3 is characterized by arthritis of one or more large joints, disturbances in heart rhythm and numbness in the arms, legs, hands, or feet.

Arthritis is a leading cause of Lyme disease-associated morbidity. Highly inflammatory aspects of Lyme arthritis that happens in the third stage can lead to cartilage and bone erosion with permanent joint dysfunction.

Thus, the correct answer is option C.
