Seroconversion to IgG anti-HEV antibodies in goats from a prospective study in a closed herd in Virginia. The kids born to seronegative dams from a known seropositive goat herd were monitored for evidence of HEV infection for a total of 14 weeks from the time of birth. The weekly serum samples were tested by an ELISA for IgG anti-HEV. The ELISA OD values (Y-axis) are plotted along the X-axis which showed the ages of the animals (dates when the samples were collected). The ELISA cutoff value that is indicated with a dotted line was set as 3 standard deviations above the mean OD value of the day 0 serum samples.
