过去二十年来，泰国的性工作模式发生了巨大转变，从直接商业场所转向间接场所和非场所场所。这项以受访者为主导的抽样调查于 2007 年在曼谷的非场所环境中针对女性性工作者 (FSW) 进行，旨在试点一种新方法对这一隐藏人群进行监测。 15 名初始参与者招募了 707 名同意的参与者，他们完成了行为问卷，并提供口腔液用于 HIV 检测，并提供尿液用于性传播感染 (STI) 检测。 HIV 总体患病率为 20.2%（95% 置信区间 [CI] 16.3-24.7）。四分之三的女性生活在街头（75.8%，95% CI 69.9-81.1），她们的艾滋病毒感染率特别高（22.7%，95% CI 18.2-28.4）；比在场地 FSW 中进行常规哨点监测 (2.5%) 的结果高出约 10 倍。 STI 患病率（沙眼衣原体和淋病奈瑟菌）分别为 8.7% (95% Cl 6.4-10.8) 和 1.0% (95% Cl 0.2-1.9)。每次性行为的较低价格和当前的 STI 感染与 HIV 感染独立相关 (P < 0.05)。参与调查的 FSW（特别是非场所 FSW）中发现艾滋病毒感染率较高，这表明需要进一步开展预防工作。此外，它还确定了通过常规哨点监测无法达到但可以通过这种调查方法获得的 FSW 较高风险部分。
The pattern of sex work in Thailand has shifted substantially over the last two decades from direct commercial establishments to indirect venues and non-venue-based settings. This respondent-driven sampling survey was conducted in Bangkok in 2007 among female sex workers (FSW) in non-venue-based settings to pilot a new approach to surveillance among this hidden population. Fifteen initial participants recruited 707 consenting participants who completed a behavioural questionnaire, and provided oral fluid for HIV testing, and urine for sexually transmitted infection (STI) testing. Overall HIV prevalence was 20.2% (95% confidence interval [CI] 16.3-24.7). Three-quarters of women were street-based (75.8%, 95% Cl 69.9-81.1) who had an especially high HIV prevalence (22.7%, 95% CI 18.2-28.4); about 10 times higher than that found in routine sentinel surveillance among venue-based FSW (2.5%). STI prevalence (Chlamydia trachomatis and Neisseria gonorrhoeae) was 8.7% (95% Cl 6.4-10.8) and 1.0% (95% Cl 0.2-1.9), respectively. Lower price per sex act and a current STI infection were independently associated with HIV infection (P < 0.05). High HIV prevalence found among FSW participating in the survey, particularly non-venue-based FSW, identifies need for further prevention efforts. In addition, it identifies a higher-risk segment of FSW not reached through routine sentinel surveillance but accessible through this survey method.
