RT Journal A1 Edlow JA T1 Diagnosing lyme disease: Getting the details right: comment on “infecting the electrocardiogram” JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2012 FD November 26 VO 172 IS 21 SP 1625 OP 1626 DO 10.1001/archinternmed.2012.4003 UL http://dx.doi.org/10.1001/archinternmed.2012.4003 AB Lyme disease is a disease of geography. Nearly 95% of those 30 000 cases occurred in 12 states, and even within those states, the incidence is highly focal.1 The increased frequency and geographic focalization can be mostly explained by a growth in the deer population (fewer natural predators and more forested habitat) and greater human exposure to those environments in which deer thrive (more people living in rural and suburban areas).2 With more deer come more ticks and tick bites.
