Most visceral larva
migrans patients are young children (age 1 to 4) as they are ones who are at highest risk from oral exposure to contaminated soil.

This study suggests that a major determinant of the risk for hematogenous dissemination of B. burgdorferi in Lyme disease
patients with erythema
migrans is the genetic subtype of the infecting strain in the skin.
In one natural history study of 55 untreated US
patients with early Lyme disease associated with erythema
migrans, 34 (62 %) developed objective signs of arthritis, 10 (18 %) developed arthralgias without arthritis, but 11 (20 %) remained completely well over a mean follow - up of 6 years [2].
Thus, the observed association between RFLP type of the infecting strain of B. burgdorferi and the presence of secondary erythema
migrans lesions provided corroboration for the blood culture results and further suggests that the RFLP type has objective clinical consequences for the
patient.
However, even for type 1 — infected
patients, more than 40 % were neither spirochetemic by the culture methods used in this study nor had multiple erythema
migrans skin lesions.
The guidelines cover three common issues faced by clinicians: management of a known tick bite, antibiotic treatment of
patients with erythema
migrans rash, and management of
patients who remain ill following antibiotic therapy for Lyme disease.
