Lyme disease is a bacterial disease which spreads through the bite of infected ticks. For lyme disease transmission, tick must be attached for 36 to 48 hours or more. Bite of immature ticks called nymphs is the cause of most of the human infection.

In response to the infection, antibodies are made by the body so most lyme disease tests include detecting these antibodies. Antibodies develop after few weeks of infection. These tests include enzyme-linked immunosorbent assay (ELISA) test and Western blot test, which are usually done to confirm the diagnosis.

Standard antibiotic treatment for Lyme disease is safe during pregnancy. The antibiotic amoxicillin is usually taken three times a day for two to three weeks. If a person is allergic to amoxicillin, then doctor might prescribe cefuroxime, a different antibiotic, which is taken twice daily instead.

Even though the bacteria are no longer present a positive blood tests will continue to test positive for several months or years. Unfortunately, in the case of bacterial infections, these antibodies do not prevent someone from getting lyme disease again if another infected tick bites them.

Lyme disease is an infectious disease. It is caused by the Borrelia bacterium. Lyme disease is spread by ticks. The most common sign of infection is an expanding area of redness on the skin, known as erythema migrans, that appears at the site of the tick bite about a week after it occurred.
