Where there are ticks, there’s often Lyme disease

Lyme disease is caused by an infection that is most often transmitted by ticks, but it can also be transmitted from mother to child during pregnancy.

Ticks can attach to your body without being seen or felt, and diagnosis can be difficult due to symptom presentation, testing protocols and other challenges.
