Who is at risk of getting Lyme disease?

The risk of exposure to ticks is greatest in the woods and in the edge area between lawns and woods; however, ticks can also be carried by animals onto lawns and gardens and into houses by pets. Campers, hikers, outdoor workers, and others may be exposed to infected ticks in wooded, brushy, and grassy places. People who spend time in heavily wooded areas where infected ticks are common are at higher risk of exposure. 

Ticks can attach to any part of the human body but are often found in hard-to-see areas such as the groin, armpits, and scalp. In most cases, the tick must be attached for 36-48 hours or more before the Lyme disease bacterium can be transmitted. 
Although in theory Lyme disease could be spread through blood transfusions or other contact with infected blood, there are no known cases of that happening. There is no evidence that Lyme disease is transmitted from person-to-person through touching, kissing, or having sex with a person who has Lyme disease. There are no reports of Lyme disease transmission through breast milk.
