Sexual networking in popular tourist destinations is a problem worldwide. In Peru, locals sexually interacting with travelers bridge high-risk groups, the general population, and travelers.
A cross-sectional study was conducted in Cuzco about sexual behavior among young Peruvians who admitted having sex with travelers. A subgroup of the participants had serologic testing for Chlamydia trachomatis, Herpes simplex virus (HSV) type 2, and Treponema pallidum.
Eighty-eight subjects volunteered for blood sampling. Their mean age was 22.9 years (+/-4.1) and 53.4% were male. The majority were single (86.2%), but 12.6% had a stable relationship. The median number of sexual partners in the 3 months prior to the study was 2 [interquartile range (IQR): 1-4]. During that period, 43.1% reported foreign partners, 28.4% reported foreign and Peruvian partners, 17% reported Peruvian partners, and the remaining 11.5% reported combinations of Peruvian, foreign, and sex workers partners. The median number of foreign partners in the 12-month period prior to the study was 4 (IQR: 2-8). Only 25.3% reported consistent condom use. Alcohol (69%) and drugs (36.8%) were commonly used before sexual activity. Seventy-eight percent tested positive for HSV type 2, 25% for C trachomatis, and 1.1% for T pallidum.
The core group of young Peruvians we report on demonstrated a high-risk sexual behavior and a high prevalence of sexually transmitted infections. Our results underscore the need for education on safer sex practices among this group and among travelers.
在热门旅游目的地进行性交易是一个全球性问题。在秘鲁，与旅行者发生性关系的当地人连接了高风险群体、普通人群和旅行者。
在库斯科进行了一项横断面研究，调查了与旅行者发生过性关系的年轻秘鲁人的性行为。参与者的一个亚组进行了沙眼衣原体、单纯疱疹病毒 2 型和梅毒螺旋体的血清学检测。
88 名受试者自愿接受采血。他们的平均年龄为 22.9 岁（+/-4.1），53.4%为男性。大多数人是单身（86.2%），但 12.6%有稳定的关系。研究前 3 个月的性伴侣中位数为 2 [四分位距（IQR）：1-4]。在此期间，43.1%报告有外国伴侣，28.4%报告有外国和秘鲁伴侣，17%报告有秘鲁伴侣，其余 11.5%报告有秘鲁、外国和性工作者伴侣的组合。研究前 12 个月的外国伴侣中位数为 4 [IQR：2-8]。只有 25.3%报告始终使用避孕套。性活动前，酒精（69%）和毒品（36.8%）通常被使用。78%的人检测出单纯疱疹病毒 2 型阳性，25%的人检测出沙眼衣原体阳性，1.1%的人检测出梅毒螺旋体阳性。
我们报告的年轻秘鲁人的核心群体表现出高风险的性行为和高发性传播感染率。我们的研究结果强调了在这一群体和旅行者中开展安全性行为教育的必要性。
