  • What exactly is Lyme disease?
    MedlinePlusMay 2026

    Lyme disease is a bacterial infection you get from the bite of an infected tick. At first it causes symptoms like a rash, fever, headache, and fatigue, but if untreated it can spread to your joints, heart, and nervous system.

  • How do I get Lyme disease from a tick bite?
    MedlinePlusMay 2026

    An infected tick carrying the bacteria must bite you and stay attached to your skin for more than 24 hours to spread the infection. The ticks that carry Lyme disease are blacklegged ticks (also called deer ticks) found mainly in the Northeast, Mid-Atlantic, Upper Midwest, and northern California.

  • Am I more at risk for getting Lyme disease?
    MedlinePlusMay 2026

    You're more likely to get Lyme disease if you spend time outdoors in warm months (April-September) when ticks are most active, especially in areas where infected ticks live like the Northeast and Upper Midwest.

  • Are there different stages of Lyme disease?
    MedlinePlusMay 2026

    Yes, Lyme disease has different stages. Early-stage Lyme disease causes a rash, fever, and flu-like symptoms, while late-stage disease can affect your joints, heart, and nervous system if left untreated.

  • Can pets also get Lyme disease?
    MedlinePlusMay 2026

    Yes, pets like dogs and cats can get Lyme disease from tick bites just like humans can. If you find a tick on your pet, remove it carefully and watch for signs of illness.
