[Anti-rubella virus IgG in urine: epidemiological application of a new enzyme-liked-immunosorbent assay (ELISA)].

Objectives: To evaluate the utility of urinary assessment for epidemiological studies of rubella, we measured anti-rubella virus immunoglobulin G (anti-RV IgG) using samples from pediatric patients with initial rubella infection, healthy volunteers who received a prophylactic inoculation of live rubella vaccine, and 3 years-old children undergoing a health examination at a community health center.

Methods: Blood and urine samples were collected from 12 of spontaneous rubella cases treated at 7 local pediatric clinics during acute and convalescent stages. In addition, blood and urine samples were collected from 17 healthy volunteers receiving prophylactic rubella vaccination immediately before, and 3 and 6-7 weeks after vaccination.
