Lyme Disease - What Increases Your Risk

What Increases Your Risk

The main risk factor for Lyme disease is exposure to ticks that are infected with Lyme disease bacteria. In areas where Lyme disease is widespread, several factors may increase your risk, including:

• Spending time outdoors during the warm months of the year when ticks are most active. Most cases of Lyme disease occur in the northeastern United States and Canada when infected ticks are most prevalent—usually between May and November, with peak activity in June and July.
• Working or playing in grassy or wooded areas doing things like gardening or yard work, hiking, camping, hunting, or fishing.
• Having indoor/outdoor pets. They can bring infected ticks into the house. Although dogs and cats can become infected with the Lyme disease bacteria, they cannot pass the illness to humans. However, the infected ticks can drop off the animals and then bite and infect humans. Animals may have symptoms similar to those seen in people, including fever and swollen joints. A vaccine for dogs is available in some areas.
• Having a stone fence or a bird feeder near your house. Stone fences often become homes for mice, and mice may feed on spilled seed from a bird feeder. Where there are mice, there are ticks.

Remove ticks right away, as soon as you notice them. Your risk for getting Lyme disease increases the longer a tick is attached to your body. Ticks generally cannot transmit Lyme disease until they are attached for at least 36 hours.
