Asymptomatic Visceral Leishmaniasis, Northern Israel

摘要

Asymptomatic human visceral leishmaniasis was identifiedin Israel by using an enzyme-linked immunosorbent assay.Positive serum samples were more prevalent in visceral leish-maniasis–endemic (2.97%) compared to nonendemic (1.01%)regions (p=0.021). Parasite exposure was higher than expect-ed, despite the small number of clinical cases, suggesting fac-tors other than infection per se influence clinical outcome.
