What does a Lyme disease rash look like?

The rash (erythema migrans) appears 3-30 days after tick bite. It starts small and expands to 12+ inches, often with a central clearing creating a 'bull's-eye' pattern. About 20-30% of people don't develop a rash at all.

How do I remove a tick properly?

Use fine-tipped tweezers to grasp the tick close to skin. Pull upward with steady pressure—don't twist. Clean the area with alcohol or soap and water. Save the tick in a sealed bag with the date. Don't use petroleum jelly or heat.

How long does a tick need to be attached?

Ticks must be attached for 36-48 hours to transmit Lyme disease bacteria. This is why prompt tick checks and removal are crucial. Other tick-borne diseases can transmit faster, so always remove ticks immediately.

Can Lyme disease be cured?

Yes, Lyme disease is curable with antibiotics, especially when caught early. Early-stage requires 2-3 weeks of oral antibiotics. Later-stage may need 2-4 weeks or IV antibiotics. About 10-20% experience persistent symptoms after treatment.

What happens if untreated?

Untreated Lyme can spread to joints, heart, and nervous system causing: severe joint pain/swelling, facial paralysis, heart palpitations, dizziness, nerve pain, cognitive difficulties, and arthritis. Early treatment prevents these complications.

Where is Lyme disease most common?

Most prevalent in the Northeast (Maine to Virginia), upper Midwest (Minnesota, Wisconsin), and parts of the Northwest. Over 95% of cases occur in 14 states. Check the live outbreak data above for current activity in your area.
