This engorged tick is infected with the bacterium spirochete.

A tick latches onto skin, where it then feeds on blood.

Lyme disease gets its name from the unusual grouping of illness made aware by mothers of infected children in Lyme, Connecticut, in 1975.

Lyme disease has been reported most often in the northeastern United States, but it has been reported in all 50 states.

Lyme disease initially affects the skin, causing an expanding reddish rash similar to a target or bull's-eye.

If left untreated, weeks to months after the rash, the bacterium and its effects can spread throughout the body to affect the joints, heart, and nervous system.

The later phases of Lyme disease can inflame the heart muscle, cause facial paralysis, meningitis, and arthritis.

Doctors can diagnose Lyme disease by process of elimination.

Most Lyme disease is curable with antibiotics, depending on the stage of the disease.

Swollen and painful joints can be treated by arthrocentesis, a procedure that removes fluid from the joint by needle and syringe.

When outdoors, guard yourself from Lyme disease by using insect repellant and wearing long clothing to protect skin.

Vaccines for Lyme disease were pulled in 2002, pending further research.

Phase 1: Early localized disease

The site where the tick bites the body is where the bacteria enter through the skin. Within days to weeks of the tick bite, the local skin around the bite develops an expanding ring of flat redness. There may be an outer ring of brighter redness and a central area of clearing, leading to a bull's-eye or target appearance. This classic initial rash is called "erythema migrans." Multiple secondary lesions can occur that are a reaction to the infection and are not due to multiple tick bites. Patients often can't recall the tick bite (the ticks can be as small as the periods in this paragraph). Also, they may not have the identifying rash to signal the doctor. More than one in four patients never develops a rash. The redness of the skin is often accompanied by generalized fatigue, muscle and joint stiffness, swollen glands, and headache resembling symptoms of a viral infection. Later, it can produce abnormalities in the joints, heart, and nervous system.
