History of Lyme Disease
•Unusual outbreak of juvenile rheumatoid
arthritis
•First recognized in 1975 in US juvenile
arthritis(1981 researchers identified cause)
•Lyme Connecticut
•Most common vector-borne disease in the
US

CDC Statistics
•30,000 cases of Lyme disease reported each
year in the United States
•Lyme disease cases are concentrated in the
Northeast and upper Midwest, with 14 states
accounting for over 96% of cases reported to
CDC.
•Most common age of reported cases, 5-7 yr.

Cause
•Spirochete Corkscrew shaped bacterium,
Borrelia burgdorferi
•Mice, birds, chipmunks, small mammals are
natural reservoirs for bacterium
•Deer are not competent hosts but are
important in the lifecycle of vector tick
•Bite of infected blacklegged tick (deer tick)
Blacklegged deer tick
(Ixodes scapularis)
Early Localized Disease
•Erythema migrans (EM) rash -fewer than 50%
recall having rash (Shapiro, 2014)
•May be warm to touch
•Rarely painful or pruritic
•Typically expands slowly over 3 to 30 days,
often with a central clearing resulting in a
target or Bull’s eye appearance
Early Localized Disease
•Flulike signs and symptoms(during off
months)
•Fever, chills, Headache, fatigue, anorexia
•Muscle, joint aches
•Swollen lymph nodes
Diagnosis
•Possible exposure
•Signs and symptoms
•ELISA test- if negative, no further testing
•Western blot test(+ in 20-40% of EM
patients)
Blood test- testing for antibodies to the
bacteria (borrelia burgdorferi)
•Co-infection testing for other bacteria found
in ticks
Transmission
•Infected Tick attaches to human body (often
hard to see areas; belt line, axilla, inguinal
area, popliteal fossa, scalp (Shapiro, 2014)
•Usually must attach for 24-36 hours to
transmit
•Bacteria multiply at site of bite
•3-32 days after bite, bacteria migrate from
the site to surrounding skin
• spread through lymphatic system to organs
www.jlgh.org
Early Disseminated Disease
•Days to weeks following infection
•Multiple EM lesions may occur
•Acute neurologic or cardiac involvement
•Bells palsy (cranial nerve VII)
•Lymphocytic meningitis
•Radiculopathy
meningoradiculitis
•Neuroborreliosis
http://www.hopkinsrheumatology.org/specialty-clinics/lymedisease-clinical-research-center/what-to-do-after-a-tick-bite/
Neuroborreliosis
•one or more meninges or nerves inflamed
•10-15% of infected patients
•Sub-acute or chronic infection of peripheral
or central nervous system
•Lyme encephalopathy-cognitive and memory difficulties
- fatigue, malaise
Early Disseminated Disease
Cardiac involvement/Carditis (up to 7
mo. Later)
•Various degrees of AV block
•Myopericarditis- can cause dizziness.
Palpitations, shortness of breath,
syncope
•Complete heartblock
•Most common in 15-45 yr. olds
Treatment of Carditis
•IV Antibiotics
•Admit if PR > 30 msec in 1st degree block
or if 2nd or 3 degree block
•Temporary pacer
Late Lyme Disease
Months to a few years following infection
•Intermittent or persistent arthritis
•Neurologic disorders
polyneuropathy (CDC,2016)
Memory, sleep disturbances
Numbness
Nerve paralysis
Pain
Post Treatment Lyme Disease
Syndrome
•Not uncommon for patients treated
with 2-4 wks of antibiotics to have
lingering fatigue, muscle or joint aches
for 6 months or more
•Unknown cause (? Residual damage to
tissue or immune system)
Treatment
Antibiotics
• Doxycycline for non-pregnant or nonlactating adults and children >8 yr. old
•Amoxicillin
•IV ceftriaxone (if neurologic symptoms)
•May need second course (additional 3-4
wks)
Prevention
•Avoid wooded or high grass areas with leaf
litter and edge of yard near woods
•Walk in center of trails
•Cover arms and legs with light colored
clothing, tuck pant leg into socks
•Use insect repellents- 20% or more DEET
•Clothing, tents etc can be treated with
permethrin (kills ticks on contact) not for skin
Landscape to create a tick free zone
Check for Ticks!
•After being in woods or high risk area
•Nymphs are small and hard to see
(poppy seed to sesame seed)
•If removed promptly, less likely to get LD
•Wash and dry clothes at high
temperature
•Keep pets protected
Removal
•Fine tip tweezers
•Tick remover (not recommended by CDC)
•Grasp as close to skin surface as possible
•Pull upward with steady even pressure
•Twisting or jerking may break off
•Do not use vaseline, match ,nail polish etc
•Wash with 70% isopropyl alcohol, iodine
or soap and water

Vaccination?
•Lyme disease is the most common tickborne illness in northern hemisphere
•Marked increase in incidence
•Long term effects documented
•Cost of care estimated between $712
million to $1.3 billion each year
(Kaaik,Luyties, 2015)
Rocky Mountain Spotted Fever
Rickettsia rickettsii
•20% mortality if untreated
•Fever, Headache, myalgia, cough, GI
symptoms, muscle pains
•Faint rash day 3 or 4 or none
•Vascular damage
•Death after day 5
www.dailymail.co.uk
STARI
•Southern tick-associated rash illness
•Rash looks like Lyme disease EM
•Similar symptoms, not linked to arthritis
or chronic disease
•Lone Star Tick bite, Amblyomma
