What Causes Lyme Disease?

Lyme disease is carried by the blacklegged tick, also known as the deer tick.

When an infected tick bites you, a bacteria calledBorrelia burgdorferipasses from the tick into your bloodstream.

In order for this to happen, the tick must be attached to you for 36 to 48 hours.

Most people are infected when they’re bitten by immature ticks, which can be difficult to see.

Untreated cases can cause serious problems or lead to a fatal condition.

This stage can begin weeks, months, or years after the tick bite.

Some see relapses of their condition despite treatment, something thats commonly termed chronic Lyme disease.

Theres some debate about why PTLDS occurs in some but not others.
