Self-collected samples have been shown to be an acceptable and sensitive method for the detection by polymerase chain reaction (PCR) of sexually transmitted infections (STIs) among women. GOAL The goal of the study was to compare self-collected sampling methods to conventional practitioner endocervical sampling for the PCR detection of Chlamydia trachomatis and Neisseria gonorrhoeae to compare two self-collected sampling methods for the detection of T vaginalis by PCR. ⋯ Self-collected specimens offer women in remote communities an acceptable and sensitive alternative method of testing for STIs. The low sensitivity of N gonorrhoeae PCR of urine specimens may reflect poor transport and storage conditions, which we have shown can be improved by freezing urine specimens and reducing transport delays.

In the Netherlands 73% of cases of neonatal herpes are caused by herpes simplex virus type 1 (HSV-1), whereas in the United States a majority are caused by HSV type 2 (HSV-2). GOAL To understand this difference we undertook a seroepidemiological study on the prevalence of HSV-1 and HSV-2 among pregnant women. ⋯ The seroprevalence of HSV-1 and HSV-2 antibodies among pregnant women in the Netherlands shows significant geographical differences, which were attributed to ethnical variation. However, the epidemiologic differences did not correlate with the incidence of neonatal herpes in the Netherlands.
