Lyme disease is not hereditary. It is an infectious disease caused by the bacterium Borrelia burgdorferi, which is typically transmitted to humans through the bite of infected blacklegged ticks. Lyme disease is not passed down from parent to child through genetic material. However, some studies suggest that certain genetic factors may affect a person’s susceptibility to Lyme disease and their ability to mount an effective immune response against the infection. Additionally, it is possible for a pregnant woman with Lyme disease to transmit the infection to her unborn child, but this is rare.
