A tick bites a host animal, then burrows its head under the skin. While the bite isn't painful and can go relatively unnoticed by the host organism, the tick can contain harmful bacteria that can cause subsequent maladies. Proper removal of the tick is key in preventing the release of this bacteria.
Erythema migrans (EM) rash: Occurs in approximately 70 to 80 percent of infected persons. Begins at the site of a tick bite after a delay of 3 to 30 days (average is about 7 days) Expands gradually over a period of days reaching up to 12 inches or more (30 cm) across. May feel warm to the touch but is rarely itchy or painful. Sometimes clears as it enlarges, resulting in a target or âbullâs-eyeâ appearance.
