7 weeks after the tick bite?
24 Jul 2009
Lyme disease is caused by the bacteria Borrelia burgdorferi (B. burgdorferi). Certain ticks carry the bacteria. The ticks pick up the bacteria when they bite mice or deer that are infected with Lyme disease. You can get the disease if you are bitten by an infected tick.
There are three stages of Lyme disease.
Stage 1 is called primary Lyme disease.
Stage 2 is called secondary Lyme disease.
Stage 3 is called tertiary Lyme disease.
Risk factors for Lyme disease include walking in high grasses, doing activities that increase tick exposure, and having a pet that may carry ticks home.
Not everyone infected with the bacteria gets ill. If a person does become ill, the first symptoms resemble the flu and include:
There may be a "bulls-eye" rash, a flat or slightly raised red spot at the site of the tick bite often with a clear area in the center. It can be larger than 1 - 3 inches wide.
Symptoms in people with the later stages of the disease include:
Unusual or strange behavior
Note: Deer ticks can be so small that they are almost impossible to see. Therefore, many people with Lyme disease never even saw a tick.
Treatment (Early Lyme Disease)
Usually involves antibiotics for three weeks.
Doxycycline, Amoxycillin or Cefuroxime are the drugs of choice.
Azithromycin can be used but 10 days treatment is recommended.
