Deer Ticks Positive for Lyme Disease in Chicago

In an effort to minimize risk for acquiring tickborne diseases, the
Cook
County Department of Public Health (CCDPH) is issuing a warning about
the
discovery of deer ticks in forest preserve settings in southwest
suburban
Cook County.

Testing done last month found ticks positive for Borrelia burgdorferi,
the
bacterium that causes Lyme disease, a potentially serious illness that
can
affect humans and animals. "The deer tick is uncommon throughout most
of
suburban Cook County and the risk of contracting Lyme disease remains
low,"
said CCDPH chief operating officer, Stephen A. Martin, Jr., Ph.D,
M.P.H.
"But several diseases can be transmitted by tick bites, so people
living in
densely wooded subdivisions or spending time outdoors need to know how
to
avoid tick bites."

The risk of exposure to ticks is greatest in wooded or brushy areas. To
contract Lyme disease, a person must be bitten by a deer tick that is
infected with the Lyme disease bacteria. Ticks are most likely to
spread
disease during the nymph stage, when they are very small and can feed
without being detected.

"Although deer ticks are generally active during warm weather, ticks
can be
found in the winter if the ground temperature reaches 40 F," said Dr.
Martin. "With the weather constantly changing in our area, it is
possible to
have warm enough days, even during the winter, that could activate the
tick
population." Early symptoms of Lyme disease include a characteristic
"bulls-eye" rash, consisting of an expanding reddened area, sometimes
with a
clear area in the middle, at the original site of the tick bite. The
rash
may expand in size to cover a very large area, or even appear in
several
places on other parts of the body. Other symptoms may occur and can
include
fever, swollen lymph nodes, headache, chills, and pain in the muscles
or
joints. If left untreated, Lyme disease infection can spread to the
musculoskeletal system, heart, and the nervous system.
