BACKGROUND

RESULTS

Maines case rate for Lyme disease was 83.7 cases per
100,000 persons in 2012, which was an all-time high.
Lyme disease is the most common vector-borne disease
reported in the US and the 3rd most commonly reported
infectious disease in Maine.
In order to prevent the transmission of Lyme disease, quick
identification of a tick and prompt removal are critical. 1
The rate of transmission increases exponentially the longer
the tick is attached from 24 to 72 hours. 1
The use of protective behaviors to prevent Lyme disease has
been shown to be significantly correlated to knowledge of the
disease. 2
In order to educate Mainers to protect themselves from ticks
and Lyme disease, public forums were planned by Maine CDC
and partners.

Of the 168 participants who signed in at the forums, 85 (50%) completed the
paper-based questionnaire. Of those 85 participants, 62 (73%) reported a
medium to high level of knowledge about ticks or Lyme disease prior to the
forums.
Of the 168 participants who signed in at the forums, 110 (68%) provided an
email address and were asked to complete an electronic-based survey. Of
those 110 participants, 34 (31%) completed the survey and 33 (97%) of
those participants reported a medium to high level of knowledge about ticks
or Lyme disease after the forums.

RESULTS

METHODS
Eight Lyme disease forums were held in public health districts
from May 1 August 31, 2013.
An epidemiologist provided Lyme disease prevention
messages and an expert panel of health care providers,
biologists, veterinarians, and epidemiologists answered
questions.
Participants completed a paper-based questionnaire about
their knowledge of ticks and Lyme disease at the end of the
forum.
Participants who provided an email address were asked to
complete an electronic-based survey via SurveyMonkey after
all forums were completed.

CONCLUSIONS

90%

Participants in the Lyme disease forums reported an increase in
knowledge of ticks and Lyme disease.
In addition, the majority of participants reported completing tick
checks as part of a Lyme disease prevention plan.
Although participant responses to the paper-based questionnaire
and electronic-based survey were not linked, it appears this health
education and outreach effort was successful in promoting Lyme
disease awareness and prevention.
Additional evaluation of community education efforts is needed to
see if these health behaviors are sustained over time.
