High endemicity of human T-cell lymphotropic virus type 1 among pregnant women in peru.

Human T-cell lymphotropic virus type 1(HTLV-1) is associated with adult T-cell leukemia, tropical spastic paraparesis, and other immune-mediated diseases. There are reports of groups with high prevalences of HTLV-1 infection in Peru, but there is limited knowledge of the epidemiology of infection or which routes of infection are most important. We studied 2,492 women presenting to a large maternity hospital in Lima for prenatal, delivery, or abortion services. HTLV-1 seropositivity was confirmed in 42 women (1.7%; 95% confidence interval, 1.2-2.2). Seroprevalence increased with age but did not vary by region of birth or recency of migration to Lima. Age greater than 30 years and sexual intercourse before 20 years of age were strongly and independently associated with infection. History of abortion and history of transfusion were of borderline significance. Women whose male partner had a characteristic that might be a marker for risk of sexually transmitted infections were also more likely to be infected. HTLV-1 is common among Peruvians throughout the country and is maintained by a low level of neonatally acquired infection that is amplified by sexual transmission. In addition to screening of the blood supply, instituted in 1997, programs designed to reduce neonatal and sexual transmission should be effective.

Female prisoners' preferences of collection methods for testing for Chlamydia trachomatis and Neisseria gonorrhoeae infection.

BACKGROUND: There is an increasing reliance on noninvasive techniques to collect specimens for the detection of sexually transmitted infections. The acceptability of these methods among the general population has been explored, but little is known about their acceptability among women confined in prison. GOAL: The goal was to compare female prisoners' preferences for collection of specimens (self-collected vaginal swab specimens, urine collection, or pelvic examination) for detection of Chlamydia trachomatis and Neisseria gonorrhoeae. STUDY DESIGN: A cross-section of inmates in a large federal prison provided urine samples and self-collected vaginal swab specimens. Women then completed a questionnaire regarding the ease of each method and their preferences for future specimen collection. RESULTS: A total of 535 women between the ages of 18 and 52 years (median = 33) participated in the study. More than half of the participants (57%) reported no difference between urine and swab in terms of ease of collection. Approximately 30% of participants said they would prefer to give a swab specimen in the future rather than collect urine (21%), but nearly half of the women expressed no preference for one method over the other. Most participants (60%) expressed a preference for providing a self-collected swab specimen rather than having a pelvic examination (23%), but nearly 17% expressed a preference for one over the other. CONCLUSION: The study population of female federal prisoners expressed no aversion to the self-collection of either vaginal swab or urine specimens for STD testing. A majority of participants expressed a preference for noninvasive techniques rather than a pelvic examination.
