“…Curiously, the prevalence of HBV found among FSW in Goiânia was similar to those observed by Pando et al 36 in Argentina (14.4%; 95%CI 11.8–17.6), Leon et al 19 in Bolivia (13.1%; 95%CI 7.8–21.2), and Camejo et al 3 in Venezuela (13.8%; 95%CI 9.7–18.9), suggesting a common HBV distribution among FSW in these countries.…”

OBJECTIVETo estimate the prevalence of hepatitis B virus and C virus infections and their genotypes and analyze the risk factors for the markers of exposure to hepatitis B virus in female sex workers in a region of intense sex trade.METHODSThis is a cross-sectional study performed with four hundred and two female sex workers in Goiânia, Brazil. Data have been collected using the Respondent-Driven Sampling. The women have been interviewed and tested for markers of hepatitis B and C viruses. Positive samples have been genotyped. The data have been analyzed using the Respondent-Driven Sampling Analysis Tool, version 5.3, and Stata 11.0.RESULTSThe adjusted prevalence for hepatitis B virus and C virus were 17.1% (95%CI 11.6–23.4) and 0.7% (95%CI 0.1–1.5), respectively. Only 28% (95%CI 21.1–36.4) of the participants had serological evidence of vaccination against hepatitis B virus. Being older (> 40 years), being single, having a history of blood transfusion and use of cocaine, and ignoring the symptoms of sexually transmitted infections were associated with positivity for hepatitis B virus (p < 0.05). We have detected the subgenotype A1 of hepatitis B virus (n = 3) and the subtypes of hepatitis C virus 1a (n = 3) and 1b (n = 1).CONCLUSIONSWe can observe a low prevalence of infection of hepatitis B and C viruses in the studied population. However, the findings of the analysis of the risk factors show the need for more investment in prevention programs for sexual and drug-related behavior, as well as more efforts to vaccinate this population against hepatitis B. The genotypes of the hepatitis B virus and C virus identified are consistent with those circulating in Brazil.

“…6 7 Information about HIV among FCSW in most South American countries is limited; recent UNAIDS estimates (2004) and a few studies have been published. [8][9][10][11] The data presented in this report represent a summary of several cross sectional studies conducted among thousands of FCSW and complements a similar analysis among MSM populations in the same region. 12 To our knowledge, this study represents the largest HIV prevalence database among FCSW in Latin America.…”

Seroprevalence of and risk factors for HIV-1 infection among female commercial sex workers in South America

Objective: Assessment of HIV prevalence and associated risk behaviours among female commercial sex workers (FCSW) across major cities in South America. Methods: Seroepidemiological, cross sectional studies of 13 600 FCSW were conducted in nine countries of South America during the years 1999-2002. Participants were recruited in brothels, massage parlours, hotels, and streets where anonymous questionnaires and blood samples were collected. HIV infection was determined by enzyme linked immunosorbent assay (ELISA) screening and western blot confirmatory tests. Results: The overall HIV seroprevalence was 1.2% (range 0.0%-4.5%). The highest HIV seroprevalences were reported in Argentina (4.5%) and Paraguay (2.6%); no HIV infected FCSW were detected in Venezuela and Chile. Consistent predictors of HIV seropositivity were: (1) a previous history of sexually transmitted infections (STI, AORs = 3.8-8.3), and (2) 10 years or more in commercial sex work (AORs = 2.2-24.8). In addition, multiple (>3) sexual contacts (AOR = 5.0), sex with foreigners (AOR = 6.9), use of illegal drugs (AOR = 3.2), and marijuana use (AOR = 8.2) were associated with HIV seropositivity in Southern Cone countries. Conclusions: Consistently low HIV seroprevalences were detected among FCSW in South America, particularly in the Andean region. Predictors of HIV infection across the continent were STI and length of commercial sex work; however, use of illegal drugs, especially marijuana, and sexual contacts with foreigners were also found to be associated risk factors in the Southern Cone region. Interventions for the control of HIV and other STI need to be region and country specific; drug use appears to have an ever increasing role in the spread of HIV among heterosexually active populations.

“…The existing literature has showed a large variation of HCV infection among FSW across different countries from less than 1% among FSW in Venezuela to more than 80% among FSW who were also injecting drugs in UK (Camejo, Mata, & Díaz, 2003; Kucirka et al, 2011; Taylor et al, 2008). Therefore, it is unclear whether the low prevalence found in the current study reflects the actual HCV epidemic among this population in China.…”

To examine the prevalence of HIV, syphilis, and hepatitis C virus (HCV) infections by demographic characteristics and identify the subgroups of female sex workers (FSW) who are at a higher risk of the infections. Secondary analysis of the 2010 National Sentinel Surveillance (NSS) data was conducted in the current study. A total of 12,622 FSW recruited from 35 NSS sites in Guangxi, China were included in the analysis. FSW were tested for HIV, syphilis, and HCV. The overall prevalence of HIV, syphilis, and HCV infections were 1.0%, 6.1% and 1.0%, respectively. The prevalence of HIV and syphilis infections were significantly higher among women who aged 40 years or older, worked in small commercial sex venues or on street, divorced or widowed, or no formal schooling. A very high HIV infection prevalence (8.2%) was observed among a small number of cross-border foreign FSW (n=49). The prevalence of HCV infection did not differ by most of the demographic characteristics. Living in other provinces or being a Zhuang-ethnic served as protective factors for HCV. The multivariable analyses confirmed the results of bivariate results suggesting higher prevalence of HIV and syphilis infections among FSW who were older, divorced or widowed, or no formal schooling. Future HIV intervention prevention efforts among FSW need to pay particular attention to these women in order to effectively curtail the infections among this most-at-risk population as well as to prevent the further spread of HIV and syphilis to other populations.
