Lyme Disease
What is Lyme Disease?
• Also known as borreliosis
• Caused by Borrelia burgdorferi bacteria
• Bacteria live in the host which is a tick
How it is transmitted
• Tick bites a human
or deer for a meal
and the bacteria is
transmitted to the
person or deer.
Host
Signs and Symptoms in Humans
• Expanding Rash
• Appears either as a
solid red expanding
rash or blotch, OR a
central spot surrounded
by clear skin that is in
turn ringed by an
expanding red rash
(looks like a bull's-eye)
Symptoms
Beginning Symptoms:
• Solid red or bull's-eye rash, usually at site of bite
• Swelling of lymph glands near tick bite
• Generalized achiness
• Headache
Symptoms
Early Disseminated Stage:
• Two or more rashes not at site
of bite
• Multiple enlarged lymph glands
• Migrating pains in
joints/tendons
• Headache
• Stiff, aching neck
• Facial palsy (facial paralysis
similar to Bell's palsy)
• Tingling or numbness in
extremities
• Abnormal pulse
• Sore throat
• Changes in vision
• Fever of 100 to 102 F
• Severe fatigue
Symptoms
Late Stage:
• Arthritis (pain/swelling) of one or two large joints
• Disabling neurological disorders (disorientation;
confusion; dizziness; short-term memory loss;
inability to concentrate, finish sentences or follow
conversations; mental "fog")
• Numbness in arms/hands or legs/feet
Treatment
• Antibiotics –Doxycycline, amoxicillin and ceftin
- four week treatment if found in early stages
• intravenous (IV) treatment and oral antibiotics
- 4-6 weeks, late stages
Deer
• Deer may carry Lyme Disease but are not
affected
• Humans, Dogs and Cats can be adversely
affected by the disease
Birds
• Carrier of Borrelia burgdorferi
• Ticks that do not have the bacteria can transmitted from a host bird
• Birds that do not have if can transmitted from feeding tick
• Birds are not affected by the bacterium
• The bacterium is spreading to new places because birds are
migrating with feeding ticks, when they finish feeding they drop up
in a new place possible miles away from where they attached to
host.
Common Ticks
Deer ticks and two other common tick species - dog ticks
and Lone Star ticks (neither of which is known to transmit
Lyme disease)
