Those women in Group 1 who have a positive HSV culture will be contacted directly when the result is known. Women in Group 2 with a positive HSV PCR result will not be contacted because routine HSV PCR and GeneXpert PCR are not FDA-cleared tests in this population; thus, we will not know the test performance characteristics (e.g., sensitivity, specificity, etc.) until completion of the trial. All pregnant women in Group 2 will receive written materials at the time of enrollment educating them on signs and symptoms of neonatal HSV disease. All postpartum women will be contacted by telephone 60-90 days post-delivery and an inquiry will be made to determine if their babies developed neonatal HSV disease.
