  • To summarize, in the spring of year one, eggs hatch into larvae, have one feeding, molt into nymphs, and go dormant.  In year 2, nymphs take their second feeding.  At this time, the nymph may transmit bacteria to humans, or to wild or domestic mammals. In the fall, nymphs molt into adult male and female ticks.  The females feed, mate, lay eggs, and die. 
  • In order to get Lyme disease, a person must be bitten by a blacklegged tick that is infected with the Lyme disease bacteria. Remember– not all blacklegged ticks are infected with the bacteria, so not all deer ticks transmit disease.  The tick must be attached for at least 24-48 hours to transmit the bacteria. The chance of getting Lyme disease increases the longer the tick is attached.
  • A person may experience multiple rashes, such as you see here.  The rash is not caused from multiple tick bites, but occurs as a reaction when the bacteria move through the body.
  • This is another example of a multiple rash.
  • This is an example of Lyme arthritis in the knee.  Joints may become red, swollen, and painful.  Lyme arthritis is generally periodic, but may become chronic in about 10 percent of people.

    7. 7. To Get Lyme Disease <ul><li>Blacklegged tick must be infected with Lyme disease bacteria </li></ul><ul><li>Only the nymphs and adult females can transmit the Lyme disease bacteria </li></ul><ul><li>Tick must be attached 24 - 48 hours before it passes bacteria to host </li></ul>
    8. 8. <ul><li>Most cases are children and middle aged people </li></ul><ul><li>54% is men </li></ul><ul><li>Most usual symptoms is neurological (54%) (248ppl) </li></ul><ul><li>Arthritis (15ppl) </li></ul><ul><li>totally 238 people were hospitalized in 2006 </li></ul>
    9. 9. Lymes Disease 3 stages
    10. 10. <ul><li>Rash (often “bulls-eye”) (red, warm, painless) </li></ul><ul><li>Fever </li></ul><ul><li>Chills </li></ul><ul><li>Headache </li></ul><ul><li>Muscle and joint pain </li></ul><ul><li>Fatigue </li></ul><ul><li>Flue like symptoms </li></ul><ul><li>Can develop Borreliosis even if rash is not present </li></ul>Stage 1 – Early localized infection 3 to 30 days after deer tick bite
    11. 11. As the rash increases in size, it clears in the middle and develops a red ring around the outside.  This rash: May expand to a very large size, Is usually not painful or itchy, and Often appears on the thighs, groin, trunk, armpit, or back. rash has been reported in about 60 to 80 percent of adults and 50 percent of children Erythema migrans (EM) rash characteristic of Lyme disease
    12. 12. Sometimes do not have bulls eye appearance (redden area without an outer ring) Not everyone gets a rash.. the early sign and symptom. (headache, fever, chills etc) is similar to other diseases, so difficult to diagnose Lymes if have no rash
    13. 13. Stage 2 – Early disseminated infection <ul><li>Days to weeks after illness onset </li></ul><ul><li>Multiple rashes </li></ul><ul><li>Facial paralysis on one side (bells palsy) </li></ul><ul><li>Fever, stiff neck, headache -> meningitis </li></ul><ul><li>Weakness, numbness, arm/leg pain </li></ul><ul><li>Irregular heart beat </li></ul><ul><li>Persistent weakness and fatigue </li></ul>
    14. 14. Multiple Rashes <ul><li>Reaction as bacteria move through body </li></ul><ul><li>Not caused by multiple tick bites </li></ul>
    15. 15. Multiple Rashes <ul><li>This is another example of a multiple rash. </li></ul>
    16. 16. Stage 3 – Late persistent infection <ul><li>Weeks to months after illness onset </li></ul><ul><li>Fatigue </li></ul><ul><li>Chronic arthritis (usually affect knees) </li></ul><ul><li>Nervous system problems (meningitis) and problems with short term memory, concentration, </li></ul>
    17. 17. Joint Swelling Joint swelling and pain may occur weeks to months after onset of illness if left untreated.
