There have been few epidemiologic studies of pubic lice in recent times, and the exact incidence is unknown.
The goal was to determine the trends of pubic lice infestation in a risk group of males and female prostitutes in an STD unit in Spain.
This was a prospective 14-year study, from 1988 to 2001, of all patients attending the STD unit in Gijón (Asturias, Spain), investigating crab lice and other STDs.
One hundred ninety-seven patients (2.2%) had pubic lice, with a male/female proportion of 1.8/1. The yearly infestation rate ranged from 1.3% to 4.6%. The mean age was 30.3 years, and 18.8% of patients were older than 35 years. There were more cases involving men who had sex with men (MSM) (P < 0.001) than those involving heterosexual men. Reinfestation occurred in 7.6% of patients, more often in males (P < 0.05) and mainly in MSM (P < 0.01).
Infestation rates were stable during the period of study, with more older patients involved than reported previously, and infestation frequently was associated with STDs. MSM were infested and reinfested more often than heterosexual men, and in general reinfestations occurred more frequently in males than in females.
近年来关于阴虱的流行病学研究较少，确切发病率尚不清楚。
旨在确定西班牙一家性病防治机构中男性和女性性工作者这一危险人群的阴虱感染趋势。
这是一项从1988年至2001年的前瞻性14年研究，对西班牙阿斯图里亚斯希洪市性病防治机构的所有患者进行调查，研究阴虱及其他性传播疾病。
197名患者（2.2%）感染阴虱，男女比例为1.8/1。年感染率在1.3%至4.6%之间。平均年龄为30.3岁，18.8%的患者年龄超过35岁。与男性异性恋者相比，男男性行为者（MSM）感染阴虱的病例更多（P<0.001）。7.6%的患者再次感染，男性更常见（P<0.05），且主要发生在男男性行为者中（P<0.01）。
在研究期间感染率稳定，涉及的老年患者比之前报道得更多，且感染常与性传播疾病相关。男男性行为者比男性异性恋者感染和再次感染阴虱的情况更频繁，总体而言，男性再次感染比女性更常见。
