RESUMO
BACKGROUND: The Zika virus outbreak has triggered a set of local and global actions for a rapid, effective, and timely public health response. A World Health Organization (WHO) initiative, supported by the Department of Chronic Condition Diseases and Sexually Transmitted Infections (DCCI) of the Health Surveillance Secretariat (SVS), Brazil Ministry of Health (MoH) and other public health funders, resulted in the start of the "Study on the persistence of Zika virus in body fluids of patients with ZIKV infection in Brazil - ZIKABRA study". The ZIKABRA study was designed to increase understanding of how long ZIKV persists in bodily fluids and informing best measures to prevent its transmission. Data collection began in July 2017 and the last follow up visit occurred in 06/26/2020. METHODS: A framework for the ZIKABRA Cooperation initiative is provided through a description and analysis of the mechanisms, strategies and the ethos that have guided the models of international governance and technical cooperation in health for scientific exchange in the context of a public health emergency. Among the methodological strategies, we included a review of the legal documents that supported the ZIKABRA Cooperation; weekly documents produced in the meetings and working sessions; technical reports; memorandum of understanding and the research protocol. CONCLUSION: We highlight the importance of working in cooperation between different institutional actors to achieve more significant results than that obtained by each group working in isolation. In addition, we point out the advantages of training activities, ongoing supervision, the construction of local installed research capacity, training academic and non-academic human resources, improvement of laboratory equipment, knowledge transfer and the availability of the ZIKABRA study protocol for development of similar studies, favoring the collective construction of knowledge to provide public health emergency responses. Strategy harmonization; human resources and health services; timing and recruiting particularities and processing institutional clearance in the different sites can be mentioned as challenges in this type of initiative.

We evaluated sweat, blood and urine specimens obtained from an ongoing cohort study in Brazil. Samples were collected at pre-established intervals after the initial rash presentation and tested for Zika virus (ZIKV) RNA presence by real-time reverse transcriptase polymerase chain reaction (rRT-PCR). From 254 participants with confirmed infection, ZIKV RNA was detected in the sweat of 46 individuals (18.1%). Sweat presented a median cycle threshold (Ct) of 34.74 [interquartile range (IQR) 33.44-36.04], comparable to plasma (Ct 35.96 - IQR 33.29-36.69) and higher than urine (Ct 30.78 - IQR 28.72-33.22). Concomitant detection with other specimens was observed in 33 (72%) of 46 participants who had a positive result in sweat. These findings represent an unusual and not yet investigated virus shedding through eccrine glands.

BACKGROUND: Syphilis is a sexually and vertically transmitted infection caused by the bacteria Treponema pallidum for which there are few proven alternatives to penicillin for treatment. For pregnant women infected with syphilis, penicillin is the only WHO-recommended treatment that will treat the mother and cross the placenta to treat the unborn infant and prevent congenital syphilis. Recent shortages, national level stockouts as well as other barriers to penicillin use call for the urgent identification of alternative therapies to treat pregnant women infected with syphilis. METHODS: This prospective, randomized, non-comparative trial will enroll non-pregnant women aged 18 years and older with active syphilis, defined as a positive rapid treponemal and a positive non-treponemal RPR test with titer ≥1:16. Women will be a, domized in a 2:1 ratio to receive the oral third generation cephalosporin cefixime at a dose of 400 mg two times per day for 10 days (n = 140) or benzathine penicillin G 2.4 million units intramuscularly based on the stage of syphilis infection (n = 70). RPR titers will be collected at enrolment, and at three, six, and nine months following treatment. Participants experiencing a 4-fold (2 titer) decline by 6 months will be considered as having an adequate or curative treatment response. DISCUSSION: Demonstration of efficacy of cefixime in the treatment of active syphilis in this Phase 2 trial among non-pregnant women will inform a proposed randomized controlled trial to evaluate cefixime as an alternative treatment for pregnant women with active syphilis to evaluate prevention of congenital syphilis.

BACKGROUND: Zika virus (ZIKV) has been identified in several body fluids of infected individuals. In most cases, it remained detected in blood from few days to 1 week after the onset of symptoms, and can persist longer in urine and in semen. ZIKV infection can have dramatic consequences such as microcephaly and Guillain-Barré syndrome. ZIKV sexual transmission has been documented. A better understanding of ZIKV presence and persistence across biologic compartments is needed to devise rational measures to prevent its transmission. METHODS: This observational cohort study will recruit non-pregnant participants aged 18 years and above with confirmed ZIKV infection [positive reverse transcriptase-polymerase chain reaction (RT-PCR) test in blood and/or urine]: symptomatic men and women in ZIKV infection acute phase, and their symptomatic or asymptomatic household/sexual infected contacts. Specimens of blood, urine, semen, vaginal secretion/menstrual blood, rectal swab, oral fluids, tears, sweat, urine and breast milk (if applicable) will be collected at pre-established intervals and tested for ZIKV RNA presence by RT-PCR, other co-infection (dengue, Chikungunya, HIV, hepatitis B and C, syphilis), antibody response (including immunoglobulins M and G), plaque reduction neutralization test (if simultaneously positive for ZIKV and dengue), and ZIKV culture and RNA sequencing. Data on socio-demographic characteristics and comorbidities will be collected in parallel. Participants will be followed up for 12 months. DISCUSSION: This prolonged longitudinal follow-up of ZIKV infected persons with regular biologic testing and data collection will offer a unique opportunity to investigate the presence and persistence of ZIKV in various biologic compartments, their clinical and immunological correlates as well as the possibility of ZIKV reactivation/reinfection over time. This valuable information will substantially contribute to the body of knowledge on ZIKV infection and serve as a base for the development of more effective recommendation on the prevention of ZIKV transmission. TRIAL REGISTRATION: NCT03106714 . Registration Date: April, 7, 2017.

BACKGROUND: Contextual factors shape the risk of acquiring human immunodeficiency virus (HIV) and syphilis. We estimated the prevalence of both infections among indigenous people in nine indigenous health districts of the Brazilian Amazon and examined the context of community vulnerability to acquiring these infections. METHODS: We trained 509 health care workers to screen sexually active populations in the community for syphilis and HIV using rapid testing (RT). We then assessed the prevalence of HIV and syphilis using RT. A multivariable analysis was used to identify factors associated with syphilis infection (sociodemographic, condom use, intrusion, population mobility, and violence). RESULTS: Of the 45,967 indigenous people tested, the mean age was 22.5 years (standard deviation: 9.2), and 56.5% were female. Overall, for HIV, the prevalence was 0.13% (57/43,221), and for syphilis, the prevalence was 1.82% (745/40,934). The prevalence in men, women, and pregnant women for HIV was 0.16%, 0.11%, and 0.07%, respectively, and for syphilis, it was 2.23%, 1.51%, and 1.52%, respectively. The district Vale do Javari had the highest prevalence of both infections (HIV: 3.38%, syphilis: 1.39%). This district also had the highest population mobility and intrusion and the lowest availability of prenatal services. Syphilis infection was independently associated with age (odds ratio [OR] 1.04, 95% confidence interval [CI]: 1.03-1.05), male sex (OR 1.32, 95% CI: 1.14-1.52), and mobility (moderate: OR: 7.46, 95% CI: 2.69-20.67; high: OR 7.09, 95% CI: 3.79-13.26). CONCLUSIONS: The large-scale integration of RT in remote areas increased case detection among pregnant women, especially for syphilis, in districts with higher vulnerability. Mobility is an important risk factor, especially in districts with higher vulnerability. Contextually appropriate approaches that address this factor could contribute to the long-term success of HIV and syphilis control programs.

Our objective was to compare HIV prevalence between two national surveys among men who have sex with men in Brazil in 2009 and 2016. HIV prevalence was estimated stratifying by age and socioeconomic status. HIV prevalence increased from 11.9% [95% confidence interval (CI): 9.9-14.3], in 2009, to 19.1% (95% CI: 16.5 - 22.0), in 2016 [odds ratio (OR) = 1.8; 95% CI: 1.3-2.3] increasing 320% among Young MSM of low SES. Political leadership is needed to develop a scientifically sound and inclusive solution.

This study aimed to analyze the detection and duration of the Zika virus (ZIKV) in plasma, urine, saliva, sweat, rectal swabs, vaginal secretions, breast milk, and semen and to explore risk factors associated with prolonged viral persistence. A prospective cohort study of symptomatic patients and their household contacts was conducted in Brazil from July 2017 to June 2019. A total of 260 individuals (184 women and 76 men) with confirmed ZIKV infection were enrolled and followed up for 12 months. ZIKV RNA was present in all body fluid specimens and detectable for extended periods in urine, sweat, rectal swabs, and semen. The longest detection duration was found in semen, with high viral loads in the specimens. ZIKV RNA clearance was associated with several factors, including age, sex, education level, body mass index, non-purulent conjunctivitis, joint pain, and whether the participant had a history of yellow fever vaccination. The influence of each of these factors on the low or fast viral clearance varied according to the specific body fluid under investigation. Recurrent ZIKV detection events after total viral clearance were observed in the cohort. Our findings provide valuable insights into the persistence and potential recurrence of ZIKV infection, highlighting the need for continued monitoring and follow-up of individuals infected with ZIKV and for effective prevention measures to reduce the risk of transmission.

With the increasing number of women deprived of liberty worldwide, implementing specific strategies that should be applied to the support offered to these women are essential social measures. This study aims to analyze the supply of resources for the social reintegration of former inmates of the Brazilian prison system from a gender perspective. We propose to conduct a documentary analysis on governmental and non-governmental strategies aimed at this audience, with a gender perspective, through an analytical matrix for the 2020-2021 period. The results show several programs in the country aimed at the social reintegration of former prisoners; however, few have a gender perspective. The theme of social reintegration and the prison system was identified in 84 news items on government agencies' websites, 20 of which were federal and 64 state, in 11 international organizations operating in Brazil, and 12 NGOs. Only six had a gender profile. The challenge for the Brazilian penitentiary system is to introduce the citizenship and human dignity approach in the prison system, including an approach to the gender issue.
Com o aumento do número de mulheres privadas de liberdade em todo o mundo, a importância da implantação de estratégias específicas que devem ser aplicadas ao suporte oferecido a essas mulheres são importantes medidas sociais. O objetivo deste estudo é analisar a oferta dos recursos para a reinserção social de egressos do sistema prisional brasileiro, com o recorte de gênero. A proposta é realizar uma análise documental sobre estratégias governamentais e não governamentais direcionadas para este público, com recorte de gênero, por meio de uma matriz analítica pelo período compreendido entre 2020 e 2021. Os resultados mostram que há no país diversos programas voltados à reinserção social de egressos do sistema prisional, entretanto poucos apresentam um recorte de gênero. O tema reinserção social e sistema prisional foi identificado em 84 notícias em sítios dos organismos governamentais visitados, sendo 20 federais e 64 estaduais. Em 11 organismos internacionais atuando no Brasil e em 12 ONGs, somente seis apresentaram recorte de gênero. O desafio do sistema penitenciário brasileiro é incluir a abordagem de cidadania e dignidade humana no sistema prisional, incluindo uma abordagem da questão de gênero.

This article aims to analyze the association between characteristics of death - type of certifier and place of death - and the odds of an external cause death being certified as unspecified in Brazil. Cross-sectional study of deaths due to external causes from the Mortality Information System, 2017. Unspecified external cause (UEC) is the outcome variable in the models. Type of certifier physician, place of death and the interaction of these variables were the explanatory variables. Confounders were controlled by multiple logistic regression. UEC were the initial underlying cause for 22% of the 159,720 deaths from external causes in Brazil and 31% of hospital deaths issued by coroners. After adjustment for confounders, the odds of UEC in a hospital death certified by a coroner was 98% greater (OR=1.98; 95%CI: 1.53; 2.56) than in a home/street death issued by another certifier. This was greater than the odds for certifications by coroners (OR=1.23; 95%CI: 1.14; 1.33) and hospital deaths (OR=1.44; 95%CI: 1.32; 1.58). External causes certified by coroners and/or occurring in hospitals have a higher presence of UEC than other deaths; and indicate the need for coordinated initiatives by the health and public security sectors.

The social act of eating together has been influenced and mediated by technologies in recent decades. This phenomenon has been investigated in different academic fields, but the topic is still in an incipient dimension, and there is a lack of consensus regarding terminology and definitions. The study aimed to characterize the main scientific findings regarding digital forms of commensality in the 21st century and to identify possible relationships between these practices and public health. A scoping review was conducted to identify papers published in different languages between 2001 and 2021. A total of 104 publications that combined commensality and technology in all contexts were included. Most studies were qualitative; from the Design and Technology field; used social media and video platforms or prototypes/augmented reality gadgets; and used different terms to refer to digital forms of commensality, allowing the analysis of the construction of field definitions over time. The intersections with health were observed from impacts on family/community engagement, culinary skills development, and mental health and eating habits. These practices also structured specific social interactions, such as virtual food communities and commensality, during the COVID-19 pandemic. This paper indicates the consistent growth of these practices and recommends the development of future research for theoretically and longitudinally deeper evaluations of the impacts of these new ways of eating together, especially regarding their effects on human health.

Most studies of sexual violence are with women, and although men who have sex with men (MSM) is the group of the men that has been most investigated for sexual violence, there are still several questions to be answered about sexual violence and sexual revictimization among MSM. This study aimed to estimate the prevalence of sexual violence in different stages of life and identify factors associated with sexual violence in adulthood among Brazilian MSM. We conducted an analysis with data from the study conducted in 2016 with 4,176 MSM from 12 Brazilian cities recruited through respondent-driven sampling (RDS), who answered a survey to a set of questions, among which some specific about sexual violence. Most participants were under 25 years old (56.5%), with more than 12 years of schooling (71.2%), mixed race (40.8%), single (86.2%), and belonging to some religion (50.9%). The lifetime prevalence of sexual violence was 20.3%. In our analyses, having experienced sexual violence in childhood and adolescence increased the odds of experiencing sexual violence in adulthood (prevalence ratio ratios [PRR] 4.93 (95% CI [1.99, 12.21]), as did experiencing physical violence (PRR 1.99; 95% CI [1.07, 3.71]) and receiving money for sex (PRR 2.26; 95% CI [1.17, 4.36]). In addition to violence in childhood and adolescence being risk factors for sexual violence in adulthood, we also observed that half of the sample experienced sexual violence repeatedly, characterizing sexual revictimization. It is important that health services are prepared to receive boys and men victims in order to reduce the chances of revictimization and other outcomes.

Discrimination due to sexual orientation (DDSO) has an important association with health outcomes among men who have sex with men (MSM). This study aimed to analyze factors associated with DDSO among MSM in 12 Brazilian cities. This is a cross-sectional study with 4,176 MSM participants recruited in 2016 which used a respondent-driven sampling method in 12 Brazilian cities. DDSO levels were previously identified by a latent class analysis based on 13 variables from the discrimination section. An ordinal logistic regression was used to assess associations with these DDSO levels, and weighted ordinal odds ratios (OR) and their respective 95% confidence intervals (95%CI) were estimated using Gile's estimator. Most participants were young (< 25 years old) black or of mixed-race (pardo), single individuals who had a religious affiliation, primary or incomplete secondary education, and a high and average socioeconomic status. More than half (65%) reported DDSO in the 12 months prior to this study. We observed an independent association among the four latent DDSO classes and the following variables: age < 25 years old (OR = 1.66; 95%CI: 1.21-2.27), white skin color (OR = 1.43; 95%CI: 1.02-2.01), history of sexual (OR = 2.33; 95%CI: 1.58-3.43) and physical violence (OR = 3.08; 95%CI: 2.11-4.49), disclosure of their sexual orientation as MSM to their fathers (OR = 2.00; 95%CI: 1.47-2.72), experienced suicidal ideation in the two weeks prior to this study (OR = 2.09; 95%CI: 1.46-2.98), and use of any illicit drugs in the last six months (OR = 1.61; 95%CI: 1.19-2.18). Our results indicate that contextual factors may contribute to high DDSO levels among MSM in Brazil. Public health policies toward human rights surveillance and protection among MSM must be urgently addressed.

This article addresses the vector, sexual and vertical transmissions of the Zika virus, a topic covered in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Although in Brazil Zika virus is transmitted more predominantly by Aedes aegypti, the vertical and sexual transmission routes are of significant importance for reproductive health. Sexual transmission demands specific prophylactic interventions, including the use of male or female condoms, especially among couples in a risk situation and planning pregnancy. Vertical transmission is linked to severe structural abnormalities of the central nervous system, and there is still no vaccine or known pharmacological resources that can prevent it. As the disease is predominantly asymptomatic, failure to comply with the basic principles of care and guidelines associated with the spread of the infection transcends the severity of the disease's symptoms. Although in Brazil Zika virus is predominantly transmitted by the Aedes aegypti mosquito, vertical and sexual transmission routes are important for reproductive health. Vertical transmission causes severe central nervous system structural abnormalities.

Este artigo aborda as transmissões vetorial, sexual e vertical do vírus Zika, tema contemplado no Protocolo Clínico e Diretrizes Terapêuticas para Atenção Integral às Pessoas com Infecções Sexualmente Transmissíveis, publicado pelo Ministério da Saúde do Brasil em 2020. Embora no Brasil o vírus Zika seja predominantemente veiculado pelo Aedes aegypti, as vias vertical e sexual de transmissão apresentam expressiva importância para a saúde reprodutiva. A transmissão sexual demanda o uso de intervenções profiláticas específicas, incluindo o uso do preservativo masculino ou feminino, principalmente entre casais que planejam gravidez. A transmissão vertical é ligada a graves anormalidades estruturais do sistema nervoso central e ainda não há vacina e nem recursos farmacológicos conhecidos que possam preveni-la. Como a doença é predominantemente assintomática, o não cumprimento dos princípios básicos de cuidados e orientações relacionadas à dispersão da infecção transcende a gravidade dos sintomas da doença.

The objective was to characterize sociodemographic, behavioral, and clinical aspects in young Brazilian military recruits according to prevalence of syphilis. This was a descriptive study based on a nationwide population-based survey in 2016 with a probabilistic sample of military recruits 17 to 22 years of age. A confidential self-applied questionnaire was used. Blood samples were drawn from participants for treponemal and non-treponemal syphilis tests. Descriptive statistical techniques were used to estimate syphilis prevalence rates and distribution of frequencies between the target variables, considering 95% confidence intervals (95%CI), after weighting the data. Of the total of 37,282 participants, 73.7% were sexually initiated. Prevalence rates for lifetime and confirmed syphilis were 1.6% and 1.1%, respectively. The following population variables showed higher prevalence of syphilis: lack of Internet access at home; initiation of sexual activity before 14 years of age; men who have sex with men; more than five sexual partners; having received presents, drugs, or other incentives in exchange for sex; and prior history of symptoms of sexually transmissible infections. An increase was observed in syphilis in Brazilian military recruits when compared to previous surveys. This increase emphasizes the importance of this sentinel population for performing active surveillance in order to support healthcare strategies for youth, including in the school system.
O objetivo foi caracterizar aspectos sociodemográficos, comportamentais e clínicos entre conscritos brasileiros, segundo a prevalência de sífilis. Estudo descritivo desenvolvido valendo-se de pesquisa nacional de base populacional, realizada em 2016, com amostra probabilística de jovens conscritos de 17 a 22 anos de idade. Realizou-se autoaplicação de questionários confidenciais. As amostras de sangue total dos participantes foram coletadas para testagem de sífilis, com a utilização de testes treponêmicos e não treponêmicos. Empregaram-se técnicas de estatística descritiva para estimar as prevalências de sífilis e a distribuição de frequências entre as variáveis pesquisadas, considerando os intervalos de 95% de confiança (IC95%), após a ponderação dos dados. Do total de 37.282 participantes, 73,7% haviam iniciado a vida sexual. As prevalências de sífilis na vida e de sífilis confirmada foram de 1,6% e 1,1%, respectivamente. As seguintes variáveis populacionais apresentaram maior prevalência de sífilis: ausência de acesso à Internet no domicílio; início da atividade sexual antes dos 14 anos; categoria de exposição homens que fazem sexo com homens; práticas sexuais com mais de cinco parcerias; recebimento de presentes, drogas ou outros incentivos em troca de sexo; e história prévia de sintomatologia de infecções sexualmente transmissíveis. Observou-se o aumento de sífilis entre os jovens conscritos brasileiros, em comparação aos inquéritos anteriores. Tal incremento reforça a importância dessa população sentinela para realizar vigilância ativa, de forma a subsidiar estratégias de atenção à saúde dos jovens, incluindo cenários escolares.

Del total de 37.282 participantes, un 73,7% habían iniciado su vida sexual. Las prevalencias de sífilis en la vida y de sífilis confirmada fueron de 1,6% y 1,1%, respectivamente. Las siguientes variables poblacionales presentaron una mayor prevalencia de sífilis: ausencia de acceso a Internet en el domicilio; inicio de la actividad sexual antes de los 14 años; categoría de exposición hombres que practican sexo con hombres; prácticas sexuales con más de cinco personas; recibimiento de regalos, drogas u otros incentivos a cambio de sexo; e historia previa de sintomatología de infecciones sexualmente transmisibles. Se observó el aumento de sífilis entre los jóvenes reclutas brasileños, en comparación con las encuestas anteriores. Tal incremento refuerza la importancia de esa población centinela para realizar una vigilancia activa, de forma que se apoyen estrategias de atención a la salud de los jóvenes, incluyendo escenarios escolares.

Zika virus (ZIKV) has been detected in blood, urine, semen, cerebral spinal fluid, saliva, amniotic fluid, and breast milk. In most ZIKV infected individuals, the virus is detected in the blood to one week after the onset of symptoms and has been found to persist longer in urine and semen. To better understand virus dynamics, a prospective cohort study was conducted in Brazil to assess the presence and duration of ZIKV and related markers (viral RNA, antibodies, T cell response, and innate immunity) in blood, semen, saliva, urine, vaginal secretions/menstrual blood, rectal swab and sweat. The objective of the current manuscript is to describe the cohort, including an overview of the collected data and a description of the baseline characteristics of the participants. Men and women ≥ 18 years with acute illness and their symptomatic and asymptomatic household contacts with positive reverse transcriptase-polymerase chain reaction test for ZIKV in blood and/or urine were included. All participants were followed up for 12 months. From July 2017 to June 2019, a total of 786 participants (284 men, 502 women) were screened. Of these, 260 (33.1%) were enrolled in the study; index cases: 64 men (24.6%), 162 (62.3%) women; household contacts: 12 men (4.6%), 22 (8.5%) women. There was a statistically significant difference in age and sex between enrolled and not enrolled participants (p<0.005). Baseline sociodemographic and medical data were collected at enrollment from all participants. The median and interquartile range (IQR) age was 35 (IQR; 25.3, 43) for men and 36.5 years (IQR; 28, 47) for women. Following rash, which was one of the inclusion criteria for index cases, the most reported symptoms in the enrollment visit since the onset of the disease were fever, itching, arthralgia with or without edema, non-purulent conjunctivitis, headache, and myalgia. Ten hospitalizations were reported by eight patients (two patients were hospitalized twice) during follow up, after a median of 108 days following symptom onset (range 7 to 266 days) and with a median of 1.5 days (range 1 to 20 days) of hospital stay. A total of 4,137 visits were performed, 223 (85.8%) participants have attended all visits and 37 (14.2%) patients were discontinued.

INTRODUCTION: This paper details the methods used in the second national Biological and Behavioral Surveillance Survey (BBSS) of HIV, syphilis, and hepatitis B and C among men who have sex with men in Brazil. METHODS: Respondent-driven sampling (RDS) was used in 12 cities in 2016. The targeted sample size was initiated with five to six seeds in each city. HIV, syphilis, and Hepatitis B and C rapid tests were offered to participants. RDS Analyst with Gile's successive sampling (SS) estimator was used to adjust results as recommended and a weight for each individual was generated for further analysis. Data for the 12 cities were merged and analyzed using Stata 14.0 complex survey data tools with each city treated as its own stratum. RESULTS: Duration of data collection varied from 5.9 to 17.6 weeks. 4,176 men were recruited in the 12 cities. Two sites failed to achieve targeted sample size due to a six-month delay in local IRB approval. No city failed to reach convergence in our major outcome variable (HIV). CONCLUSION: The comprehensive BBSS was completed as planned and on budget. The description of methods here is more detailed than usual, due to new diagnostic tools and requirements of the new STROBE-RDS guidelines.

This paper reports human immuno-deficiency virus (HIV) prevalence in the 2nd National Biological and Behavioral Surveillance Survey (BBSS) among men who have sex with men (MSM) in 12 cities in Brazil using respondent-driven sampling (RDS).Following formative research, RDS was applied in 12 cities in the 5 macroregions of Brazil between June and December 2016 to recruit MSM for BBSS. The target sample size was 350 per city. Five to 6 seeds were initially selected to initiate recruitment and coupons and interviews were managed online. On-site rapid testing was used for HIV screening, and confirmed by a 2nd test. Participants were weighted using Gile estimator. Data from all 12 cities were merged and analyzed with Stata 14.0 complex survey data analysis tools in which each city was treated as its own strata. Missing data for those who did not test were imputed HIV+ if they reported testing positive before and were taking antiretroviral therapy.A total of 4176 men were recruited in the 12 cities. The average time to completion was 10.2 weeks. The longest chain length varied from 8 to 21 waves. The sample size was achieved in all but 2 cities.A total of 3958 of the 4176 respondents agreed to test for HIV (90.2%). For results without imputation, 17.5% (95%CI: 14.7-20.7) of our sample was HIV positive. With imputation, 18.4% (95%CI: 15.4-21.7) were seropositive.HIV prevalence increased beyond expectations from the results of the 2009 survey (12.1%; 95%CI: 10.0-14.5) to 18.4%; CI95%: 15.4 to 21.7 in 2016. This increase accompanies Brazil's focus on the treatment to prevention strategy, and a decrease in support for community-based organizations and community prevention programs.
