During the summer months, the tick population in our area increases, along with the incidence of tick-borne illnesses like Lyme Disease. The resources below can help you learn about the different types of ticks and the diseases they carry, signs & symptoms of tick-borne illnesses, treatment recommendations, and instructions on how to properly remove ticks.
What is Lyme disease?
Lyme disease is a bacterial infection that can result from the bite of an infected deer tick also known as blacklegged ticks. Lyme disease was first recognized in the United States in 1975 after an unusual outbreak of arthritis near Lyme, Connecticut.
What are symptoms of Lyme disease?
Typical symptoms of Lyme disease include fever, headache, fatigue, muscle and joint aches, and swollen lymph nodes. A characteristic skin rash called erythema migrans (EM) occurs in about 70-80 percent of infected persons. EM begins within 3 to 30 days at the site of the tick bite. The average appearance of this rash occurs around seven days after the bite, and it can grow to around 12 inches or more. It may look like a “bullseye” and could feel warm to touch but is rarely itchy or painful.
In a small percentage of cases, symptoms can last for more than six months. This is sometimes referred to as chronic Lyme disease. Some patients may not experience symptoms for weeks or months after the initial bite. Symptoms of ‘late Lyme disease’ include arthritis, and pain and swelling of joints, especially the knees.
Late Lyme disease signs and symptoms include those affecting the nervous system. Other rare symptoms include irregularities of heart rhythm and problems with memory, concentration, and sleep disturbances. Lyme disease is diagnosed based on symptoms, as well as the potential for exposure to infected ticks.
How does Lyme disease spread?
Lyme disease bacteria, Borrelia burgdorferi, are spread through the bite of infected ticks. In general, ticks need to be attached for 36-48 hours before they can transmit Lyme disease bacteria. In the U.S., these ticks are found in wooded areas mainly in the northeastern, mid-Atlantic, and north-central states. According to the CDC, 95 percent of confirmed Lyme disease cases were reported from 14 states. It is the most commonly reported vector borne illness in the United States.
How do you prevent Lyme disease?
Prevention and early recognition of tick bites is key. Persons treated with appropriate antibiotics during the early stages of Lyme disease usually recover rapidly and completely. The risk of exposure to ticks is greatest in the woods and in the space between lawns and the edge of the woods. Ticks can also hitchhike to your lawn and into your house via your pet.
You can decrease your risk of being bitten by a tick by following a few precautions including:
