Lyme disease knowledge, beliefs, and practices of New Hampshire primary care physicians.

Background: Lyme disease is the most commonly reported vectorborne illness in the United States and is endemic in many counties in the Northeast, including counties in New Hampshire. Previous studies conducted elsewhere on Lyme disease have indicated substantial differences between physician practices and published consensus guidelines for diagnosis and treatment.

Methods: During 1999, we mailed a 21-item questionnaire to 600 randomly selected family practice physicians, internists, and pediatricians in New Hampshire.
