This page has research co-authored by Craig Levy, Program Manager, Vector-borne & Zoonotic Diseases Division of the Arizona Department of Health Services (ADHS).

Craig Levy's research shows that he found Borrelia burgdorferi, the spirochete bacterium that causes Lyme disease, in four percent (4%) of Ixodes pacificus (Western black-legged ticks) in the Hualapai Mountains located in Mohave County, Arizona in 1991.  His research was published in 1992.

Be sure to scroll down past the fourth and last page of the published research to read Craig Levy's July 10, 2006 letter to Tina Garcia in which he stated:

"Results of these efforts revealed no evidence of B. burgdorferi in the Hualapai Mountains."

Below Craig Levy's letter is a February 8, 2006 letter from retired Chief of Infectious Disease Services at the Arizona Department of Health Services, Dr. Victorio Vaz.  Dr. Vaz stated:

"Our data does not rule out the presence of Borrelia burgdorferi in the state, however, we have no evidence to support risk of endemic Lyme disease at this time."
