With the approach of warm weather in May, and the increase in outdoor activities, many county residents may place themselves at increased risk of exposure to Lyme disease.

Lyme disease is now the most prevalent tick-borne illness in our area. It is an infection that can cause arthritic, heart and nervous system problems. An early symptom of Lyme disease may be a discrete circular or oval rash (erythema migrans) that may continue to expand or spread. Other early symptoms include fatigue, chills and fever, headache, muscle and joint pains and swollen lymph nodes. Because Lyme disease is often difficult to diagnose, and often produces variable symptoms, it is important to consult your doctor as soon as possible.

To help prevent Lyme and other tick-related illnesses, the Nassau County Department of Health recommends that all residents take the following precautions to "Be Tick Free":

Try to stay out of tick-infected areas such as wooded areas and adjacent grasslands, high grass, dense shrubbery and areas adjacent to salt marshes

If one does go into tick areas:

• Wear light colored clothing with long sleeves and long pants tucked into socks or boots
• Use repellents as appropriate
• Check for ticks on clothing and pets

After returning home, remember to conduct full-body checks for ticks

The risk of contracting other tick-borne diseases, such as Rocky Mountain Spotted Fever, Babesiosis or Ehrlichiosis, is relatively small in Nassau County. However, since almost all residents at some time or other travel outside the County, it is advisable to be aware of Lyme disease and other tick-related illnesses.

The Nassau County Department of Health bulletin on "Lyme Disease and Other Tick Related Illnesses" is now available. The free, 4-page bulletin contains information which will help residents to

• Prevent exposure to tick bites
• Recognize symptoms of tick-borne diseases
• Seek appropriate treatment
