Implementation of a rapid diagnostic assay package for cryptococcosis, histoplasmosis and tuberculosis in people living with HIV in Paraguay.

BACKGROUND: Opportunistic infections (OIs) are common causes of mortality among people living with HIV (PLHIV). We determined prevalence and 30-day mortality due to histoplasmosis, cryptococcosis, and TB in PLHIV with advanced HIV disease (AHD). METHODS: PLHIV 18 years and older, with a CD4 + T-cell count of less than 350 cells/mm3 newly diagnosed with HIV infection or re-engaged in care after being without ART for more than 90 days (Group A). The second group included symptomatic PLHIV regardless of ART status or CD4 + T-cell count (Group B); all followed for 30 days. Detection of Histoplasma Ag (HisAg) in urine was done by enzyme immunoassay (EIA), Cryptococcus antigen (CrAg) was detected in serum and cerebrospinal fluid (CSF) specimens by lateral flow assay (LFA), and lipoarabinomannan (LAM) detection in urine was by LFA (TB LAM) and in sputum by GeneXpert for diagnosis of Mycobacterium infections. RESULTS: From August 2021 to June 2022, 491 PLHIV were enrolled; 482 (98%) had a CD4 + T-cell result, and 381 patients (79%) were classified with AHD according to CD4 + T-cell count (< 200 CD4/mm3). Frequency of an OI was 38% (n = 145/381). Antigen test positivity rate was 16% (72/467) for TB-LAM, 9% (43/464) for HisAg, and 11% (51/484) for CrAg. Twenty-one of 34 (62%) patients receiving CSF CrAg tests were positive, confirming meningitis. Significant differences in 30-day mortality were observed in patients with an OI (16%) vs. no OI (7%) (p = 0.002). Mortality was highest in patients with histoplasmosis (25%), co-infection (22%), cryptococcosis (18% overall; 19% for cryptococcal meningitis), and TB (10%). CONCLUSIONS: TB and fungal OIs, including co-infection, were common in PLHIV in Paraguay and had high associated mortality. Laboratories and health facilities need access to CD4 + T-cell testing and rapid diagnostic assays.

Intergenerational sex and early sexual debut are associated with HIV infection among transgender women in Paraguay.

INTRODUCTION: HIV prevalence among transgender women is high worldwide. The objectives of the present study were to estimate the current prevalence of HIV and identify factors associated with high HIV burden among transgender women in Paraguay. METHODS: Transgender women aged ≥15 years in four regions of Paraguay were recruited by Starfish sampling between February and March 2021. RESULTS: In total, 322 transgender women were included. Mean age was 31 years (range 15-67), and 102 had positive HIV test results (31.7%, 95% confidence interval [CI] 26.6-37.1). In multivariable analysis, factors associated with HIV infection were age at first intercourse ≤17 years (adjusted odds ratio [aOR] 5.47; 95% CI 1.05-28.42), >10 years difference in age with the last sexual partner (aOR 1.60; 95% CI 1.04-2.46), substance use (mostly cocaine) (aOR 3.00; 95% CI 1.47-6.12), higher risk perception (aOR 3.08; 95% CI 1.53-6.17), not testing for HIV (aOR 1.23; 95% CI 1.09-1.39), and accessed by a peer educator (aOR 3.86; 95% CI 1.77-8.38). CONCLUSIONS: Sexual debut as a minor and a large age difference with sexual partners are associated with high burden of HIV among transgender women in Paraguay. Our study corroborates the finding of cocaine use during sex as a risk factor for HIV. Prevention programmes must address structural and social vulnerabilities to stem the tragically high burden of HIV among transgender women.

HIV prevalence and associated risk factors among men who have sex with men in three regions of Paraguay, 2020.

BACKGROUND: Our study aimed to measure HIV prevalence and associated risk factors among men who have sex with men (MSM) in three regions of Paraguay in 2020. METHODS: MSM were recruited for cross-sectional surveys in three regions of Paraguay using respondent-driven sampling. Interview were conducted face-to-face to collect demographic characteristics and risk and preventive behaviors. The analysis assessed HIV prevalence and associated risk factors in the three samples of MSM within each region. RESULTS: A total of 1,207 MSM were recruited, including 559 in Asunción-Central, 245 in Alto Paraná, and 403 in Caaguazú. HIV prevalence was 24.2% (95% CI 20.6-27.9) in Asunción-Central, 10.2% (95% CI 6.7-14.6) in Alto Paraná, and 3.2% (95% CI 1.7-5.4) in Caaguazú. In Asunción-Central, associations with HIV were age ≥25 years (1.86, 95% CI 1.15-3.00), being employed (1.82, 95% CI 1.07-3.11), self-reporting as homosexual (1.90, 95% CI 1.06-3.43), having sex with a known HIV-positive partner acquisition (4.19, 95% CI 2.37-7.43), self-perceived as being at higher risk for HIV acquisition (4.15, 95% CI 2.54-6.77), and able to access condoms and lubricants (1.82, 95% CI 1.08-3.05). In Alto Paraná, associations with HIV were self-reporting as homosexual (4.33, 95% CI 1.19-15.65) and having higher HIV knowledge (2.53, 95% CI 0.97-6.61). In Caaguazú, associations with HIV were self-reporting as homosexual (7.06, 95% CI 1.53-32.46) and being diagnosed with depression (4.68, 95% CI 0.89-24.43). CONCLUSIONS: HIV prevalence among MSM in Paraguay varied by region, being highest in the capital and major metropolitan area of Asunción-Central, followed by the border area of Alto Paraná. While being self-identified as homosexual was associated with HIV in all three regions, other associations differed, indicating prevention programs need to be tailored to the locale.

HIV drug resistance in persons initiating or reinitiating first-line antiretroviral therapy in Paraguay: Results of a National Patient Survey.

Human immunodeficiency virus (HIV) drug resistance increases mortality and morbidity and antiretroviral therapy (ART) costs. We describe Paraguay's first nationally representative survey on pretreatment drug resistance (PDR) conducted among persons who initiated or reinitiated ART in 2019. ​​​​We conducted a cross-sectional survey of antiretroviral (ARV) drug resistance in Paraguay in 2019. Participants were sampled at four comprehensive care clinics where 90% of patients with HIV in Paraguay initiate ART. Patients included were adults ≥18 years old who initiated first-line ART or reinitiated the same first-line ART regimen after ≥3 months of discontinuation. Of 208 patients, 93.8% had no prior ART exposure, 3.8% reinitiated the same regimen, 2.4% had unknown prior ART exposure; and 31.3% had a CD4 count <200 cells/µl. Mutations associated with resistance were present in 15.4% of patients. Mutations associated with resistance to nonnucleoside reverse transcriptase inhibitors (NNRTI) were present in 13.0% of patients, nucleoside reverse transcriptase inhibitors in 4.3%, and integrase inhibitors in 3.4%. Mutations associated with resistance to tenofovir were present in 1.0% of patients and emtricitabine/lamivudine in 1.4%. ​​Nearly one in six patients had PDR in Paraguay's first nationally representative sample. High NNRTI PDR prevalence underscores the need to accelerate the transition to dolutegravir-based first-line ART. The low PDR prevalence of tenofovir and emtricitabine is reassuring as these ARVs are part of the World Health Organization (WHO)-recommended oral pre-exposure prophylaxis regimen. The high proportion of individuals initiating ART at a late disease stage highlights the need to improve treatment linkage strategies and implement WHO rapid ART initiation recommendations.

WHO method for estimating congenital syphilis to inform surveillance and service provision, Paraguay.

Problem: In Paraguay, incomplete surveillance data resulted in the burden of congenital syphilis being underestimated, which, in turn, led to missed opportunities for infant diagnosis and treatment. Approach: The prevalence of congenital syphilis, as defined by the World Health Organization (WHO), was estimated for Paraguay using the WHO congenital syphilis estimation tool. This tool was also used to monitor progress towards the elimination of mother-to-child transmission of syphilis. Local setting: The burden of syphilis in Paraguay has historically been high: its prevalence in pregnant women was estimated to be 3% in 2018. Relevant changes: The incidence rate of congenital syphilis estimated using the WHO tool was around nine times the reported prevalence. Subsequently, Paraguay: (i) provided training to improve diagnosis and case reporting; (ii) strengthened information systems for case monitoring and reporting; and (iii) procured additional rapid dual HIV-syphilis and rapid plasma reagin tests to increase syphilis testing capacity. In addition, the Ministry of Health prepared a new national plan for eliminating mother-to-child transmission of syphilis, with clear monitoring milestones. Lessons learnt: Health-care providers' reporting and surveillance procedures for congenital syphilis may not adequately reflect national and international case definitions. Use of the WHO congenital syphilis estimation tool in Paraguay drew attention to congenital syphilis as a national public health problem and highlighted the importance of comprehensive national surveillance systems and accurate data. Ongoing use of the WHO tool can track progress towards the elimination of mother-to-child transmission of syphilis by helping improve syphilis service coverage and national surveillance.

Estudio comparativo de la reacción de Mantoux con la determinación del Interferon Gamma en pacientes VIH-SIDA para el diagnóstico de la Tuberculosis latente (TBL)

Resumen La OMS estima que un tercio de la población mundial está infectada con Mycobacterium tuberculsosis, permaneciendo la mayoría de los casos en forma de TB latente (TBL). No existe un estándar de oro para el diagnóstico de la TBL, por lo cual la carga global de la misma. Objetivo: Comparar la efectividad en pacientes con VIH/SIDA de dos pruebas diagnósticas de TB latente (TBL): la Prueba de Mantoux y la determinación de Interferón Gamma en sangre periférica. Materiales y métodos: Estudio observacional, descriptivo y prospectivo con componente analítico, en el que se incluyeron consecutivamente por muestreo no probabilístico los pacientes de 18 meses a 60 años pacientes de ambos sexos, que acuden al consultorio del Programa Nacional de Control del VIH/sida con diagnóstico reciente de VIH/sida y en quienes se descartó TB activa. En todos los pacientes incluidos se realizó al mismo tiempo determinación del PPD (por inyección de tuberculina I de 2UI de potencia por inyección intradérmica en antebrazo izquierdo) y se tomó sangre periférica para determinación por el método de ELISA de la producción por los mononucleares de interferón gama en respuesta a antígeno de MTB (ELISA- QIAGEN - Germany). Resultados: Desde octubre 2017 a octubre de 2019, se identificaron 659 pacientes VIH que reunían los criterios de inclusión, de los cuales se incluyeron el 99, 9% (599 pacientes), quienes acudieron a la lectura de la prueba de la PPD. La edad media de los pacientes es de 34,1 años (DE 13,1 años), 415 (69%) son del sexo masculino. El 67,9% (407/599) procede del Dpto. Central y Asunción A todos los pacientes incluidos se les realizó la PPD y el test IGRA. La TBL se detectó en el 7,6% (46/599) pacientes, de los cuales, en 8,7% (52/599) el Gama Interferon fue positivo (IGRA) y en 3,8% (23/599) la PPD fue ≥5 (positivo). El 2% (12/599) pacientes fueron positivos para ambas pruebas. Al comparar los datos mencionados podemos observar que el IGRA resultó ser el método más efectivo para detectar la TBL, ya que con el mismo se identificó a 8,7% de los casos a diferencia de la PPD que solo permitió identificar el 2% de los mismos. El 100% (46/46) de los pacientes con diagnóstico con TBL recibieron quimioprofilaxis con Isoniacida. Conclusión: El presente estudio pretende definir el rendimiento de una nueva metodología para la detección de TB latente en una población de alto riesgo de coinfección como son los infectados con VIH.

Abstract The WHO estimates that one third of the world's population is infected with Mycobacterium tuberculosis, with the majority of cases remaining in the form of latent TB (TBL). There is no gold standard for the diagnosis of TBL, hence the global burden of it. Objective: To compare the effectiveness in patients with HIV / AIDS of two diagnostic tests for latent TB (TBL): the Mantoux Test and the determination of Interferon Gamma in peripheral blood. Materials and methods: An observational, descriptive and prospective study with an analytical component, in which patients between 18 months and 60 years of age, patients of both sexes, were consecutively included by non-probabilistic sampling, who attended the office of the National HIV / AIDS Control Program with a recent diagnosis of HIV / AIDS and in whom active TB was ruled out. In all the patients included, PPD was determined at the same time (by injection of tuberculin I of 2IU of potency by intradermal injection in the left forearm) and peripheral blood was taken for determination by the ELISA method of the production of interferon mononuclear cells. gamma in response to MTB antigen (ELISA- QIAGEN - Germany). Results: From October 2017 to October 2019, 659 HIV patients meeting the inclusion criteria were identified, of which 99.9% (599 patients) were included, who attended the reading of the PPD test. The mean age of the patients is 34.1 years (SD 13.1 years), 415 (69%) are male. 67.9% (407/599) came from the Central and Asunción Departments. All patients included underwent the PPD and the IGRA test. TBL was detected in 7.6% (46/599) patients, of which, in 8.7% (52/599) the Interferon range was positive (IGRA) and in 3.8% (23/599) PPD was ≥5 (positive). 2% (12/599) patients were positive for both tests. When comparing the aforementioned data, we can see that the IGRA turned out to be the most effective method for detecting TBL, since with it 8.7% of the cases were identified, as opposed to the PPD, which only allowed the identification of 2% of the cases. themselves. 100% (46/46) of the patients diagnosed with TBL received chemoprophylaxis with Isoniazid. Conclusion: The present study aims to define the performance of a new methodology for the detection of latent TB in a population at high risk of coinfection such as those infected with HIV.

High HIV prevalence among transgender women in Paraguay.

Transgender women have been understudied and underserved in Paraguay; data are urgently needed to understand their HIV prevention and care needs. To estimate HIV prevalence and related risk and preventive behaviors among trans women in Paraguay, we conducted a cross-sectional survey in 2017. We employed starfish sampling - a hybrid venue-based and peer-referral method combining recruitment at randomly sampled venues and randomly selected clients from program lists, followed by short-chain referrals of eligible peers. Among 304 trans women enrolled, HIV prevalence was 24.8% (95% confidence interval [CI] 18.5-31.2%), with risk increasing with age (adjusted odds ratio [AOR] 1.06 per year, 95% CI 1.03-1.10), residence in Asunción department (AOR 4.75, 95% CI 1.57-14.36), and cocaine use (AOR 2.09, 95% CI 1.11-3.95). Trans women in Paraguay need to be prioritized for interventions with high HIV prevention efficacy. Substance use interventions to address cocaine use may also yield prevention benefits for trans women in our context.

Prevalencia del VIH/Sífilis y comportamientos de riesgo en mujeres trabajadoras sexuales en Paraguay / Prevalence of HIV/Syphilis and risk behaviors in female sex workers in Paraguay

Introducción: En Paraguay, la epidemia del VIH se encuentra concentrada en población clave. La ruta principal de transmisión de las infecciones de transmisión del VIH y la Sífilis es la sexual. Las mujeres trabajadoras sexuales (MTS) presentan riesgo incrementado debido a su trabajo sexual y sus comportamientos de riesgo. Objetivo: Determinar la prevalencia de VIH/Sífilis y el comportamiento de riesgo de la población de mujeres trabajadoras sexuales en seis regiones sanitarias del país durante el año 2017. Material y Métodos: El diseño del estudio fue observacional, corte transversal. La metodología utilizada para la selección de la muestra fue la de TLS (muestreo tiempo-ubicación). Se utilizaron pruebas rápidas como tamizaje inicial en todas las mujeres que ingresaron al estudio y a la vez se aplicó un instrumento para los comportamientos de riesgo. Resultados: Ingresaron 643 MTS, la edad media fue de 27 años, donde el 50% tenían entre 22 y 34 años. El 88.11% (585) realizaba el trabajo sexual en locales (prostíbulos, saunas, salón de masajes y departamentos) y el 11.89% (58) en paradas en las calles. La prevalencia del VIH fue de 1.34% (CI95% 0.513.48) y de Sífilis 8.59% (CI95% 5.78-12.59). El uso de condón en la última relación con el cliente fue de 96.02% y del 25.78% con la pareja estable en la última relación sexual. El consumo de drogas en los últimos 6 meses por más de 25 días fue de 10.78% (44/643) para la cocaína. El 54.17% de las MTS encuestadas se consideraron en igual riesgo de adquirir el VIH en comparación con el resto de las personas. Conclusión: La prevalencia de VIH fue baja y de Sífilis elevada en MTS. Se observó bajo porcentaje de uso de condón con la pareja estable, alto consumo de drogas y baja percepción de riesgo. Es importante considerar estos aspectos en el momento de planificar las intervenciones en MTS: parejas, drogas y percepción de riesgo para que se pueda lograr la eficiencia de las mismas.

Introduction: The HIV epidemic in Paraguay is concentrated in key population. The main route of HIV and Syphilis infections transmission is sexual. Female sex workers (FSW) have increased risk due to their sex work and risk behaviors. Objective: To determine the HIV/Syphilis prevalence and risk behavior in the population of female sex workers in six health regions from the country during 2017. Material and Methods: This is a cross-sectional study. The methodology used for the selection of the sample was the TLS (time-location sampling). Rapid tests were used as initial screening of all women who entered the study and at the same time an instrument for risk behaviors was applied. Results: Of 643 FSW enrolled, the average age was 27 years, where 50% were between 22 and 34 years old. 88.11% (585) performed sex work in premises (brothels, saunas, massage parlors and departments) and 11.89% (58) at street. The HIV prevalence was 1.34% (95% CI 0.513.48) and 8.59% Syphilis (95% CI 5.78-12.59). Condom use in the last relationship with the client was 96.02% and 25.78% with the stable partner in the last sexual relationship. 54.17% of the FSW surveyed were considered at equal risk of acquiring HIV compared to the rest of the people. Conclusion: The prevalence of HIV was low and Syphilis was high in MTS. A low percentage of condom use was observed with the stable partner, high drug use and low risk perception. It is important to consider these aspects when planning interventions in MTS: couples, drugs and low risk perception so that their efficiency can be achieved.

Prevalence of Syphilis and Related Risk Behaviors Among Women in 5 Distinct Indigenous Populations in Paraguay.

BACKGROUND: The objective of this study was to measure the prevalence of syphilis among women of reproductive age from 5 distinct indigenous populations in Paraguay. We also sought to identify the demographic profile and behaviors of women with elevated prevalence of syphilis. METHODS: We conducted a population-based, cross-sectional survey among women aged 15 to 49 years from 5 distinct language families in Paraguay in 2016. The 5 language families were Guaraní, Maskoy, Mataco, Guaicurú, and Zamuco, sampled through a probability-based, multistage cluster design. Participants completed a questionnaire on demographic characteristics and risk-related behavior. Blood samples were drawn for rapid testing for syphilis with confirmation and titers. Participants provided written informed consent; minors had written parental consent and provided their own assent. RESULTS: A total of 1732 indigenous women were enrolled. Overall syphilis prevalence was 6.8% (95% confidence interval [CI], 5.6-8.0). Syphilis prevalence varied by language family/ethnic group (P = 0.010), with Mataco having the highest prevalence (8.2%; 95% CI, 5.3-11.9) and Maskoy having the lowest (2.5%; 95% CI, 1.1-4.7). Women reporting multiple partners (11.3%; 95% CI, 6.9-17.1; P = 0.031) and transactional sex in the last year (18.7%; 95% CI, 7.2-36.4; P = 0.010) had higher prevalence of syphilis. CONCLUSIONS: Our survey found high prevalence of syphilis in indigenous women in Paraguay, in association with transactional sex and multiple partners. Interventions to reduce sexual behaviors associated with an increased risk of sexually transmitted infections (STI) in indigenous women must be carried out with programs aimed at addressing transactional sex, appropriately framed to respect interculturality and an indigenous worldview.

Prevalencia de sífilis y características del comportamiento de los jóvenes indígenas del Paraguay, 2016 / Prevalence of syphilis and characteristics of the behavior of indigenous young people of Paraguay, 2016

El objetivo fue determinar la prevalencia de sífilis y características de comportamiento de los jóvenes indígenas del Paraguay en el 2016. Se realizó un estudio observacional, descriptivo de corte transversal con muestro probabilístico estratificado bietapico, que incluyó a jóvenes indígenas de 15 a 18 años de cinco familias lingüísticas de Paraguay. Se utilizó un cuestionario estructurado y para el tamizaje de sífilis se utilizó una test rápido treponémico y para confirmar los resultados reactivos se realizó VDRL, considerando como resultado positivo si el test rápido era positivo + VDRL positivo a una dilución de 1:4 o mayor y si la VDRL era menor a 1:4 con TPHA positivo. Los resultados se expresan como medidas de tendencia central, dispersión y proporciones. Ingresaron al estudio 546 jóvenes de 15 a 18 años, el 67,03% era del sexo femenino. Se identificaron 36 casos de sífilis, que representa una prevalencia de 6,6% (IC95%: 4,7-9,0). Mayor prevalencia de sífilis se observó en los jóvenes que consumieron alcohol en la última relación sexual 20,6% (14/68) (p<0,001), sexo transaccional 40% (2/5) (p=0,010) y no utilización de condón 20,6% (14/68) (p<0,001). Se encontró una alta prevalencia de sífilis en la población juvenil indígena, relacionada al consumo de alcohol en la última relación, práctica de sexo transaccional y no utilización de preservativos. Se recomienda la implementación de estrategias específicas con abordaje intercultural apropiadas para una población joven, orientadas a disminuir las prácticas de riesgo y promocionar la utilización de preservativos(AU)

Calidad y uso de información para mejorar la respuesta nacional ante el VIH / SIDA / Quality and use of information to improve the national response to HIV / AIDS

La finalidad de todo sistema de información rutinario de salud es el uso adecuado y oportuno de la información que produce para mejorar la salud de la población. Su desempeño depende de procesos determinados por factores técnicos, organizacionales y de comportamiento. El objetivo de este estudio ha sido evaluar el desempeño del sistema de información rutinario de VIH SIDA en el sistema público de salud del Paraguay. Para ello se realizó un estudio transversal descriptivo durante el año 2016, aplicando un cuestionario estándar de evaluación según el modelo PRISM. Se incluyó a 154 trabajadores del sector salud de 76 establecimientos públicos de 4 regiones sanitarias, mediante un muestreo basado en el aseguramiento de la calidad de lote. Los resultados señalaron que el uso de la información fue de 25,8% y que la calidad de los datos fue de 75,6%. Presentaron bajo desempeño los procesos de recolección, presentación, retroalimentación y análisis de los datos. Entre los determinantes se identificó bajo desempeño en los siguientes factores: a) el nivel de conocimiento de los formularios y la capacidad de resolver problemas; b) uso de software; y c) gestión de datos. La promoción de la cultura de la información fue de 75,8%. Como conclusión se demuestra que la calidad no garantiza el uso de la información, que ésta no está vinculada a la toma de decisiones y que para revertir el bajo desempeño es necesario desarrollar capacidades e incidir sobre los determinantes identificados

The purpose of any routine health information system is the adequate and timely use of the information it produces to improve the health of the population. Its performance depends on processes determined by technical, organizational and behavioral factors. The objective of this study was to evaluate the performance of the routine HIV AIDS information system in the public health system of Paraguay. To this end, a descriptive cross-sectional study was carried out during 2016, applying a standard evaluation questionnaire according to the PRISM model. 154 health sector workers from 76 public health establishments in 4 health regions were included, through sampling based on batch quality assurance. The results indicated that the use of the information was 25.8% and that the quality of the data was 75.6%. The processes of collection, presentation, feedback and analysis of the data presented low performance. Among the determinants, low performance was identified in the following factors: a) the level of knowledge of the forms and the ability to solve problems; b) use of software; and c) data management. The promotion of the information culture was 75.8%. In conclusion, it is demonstrated that quality does not guarantee the use of information, that it is not linked to decision-making and that in order to revert low performance it is necessary to develop capacities and influence the identified determinants

Mortality Rate and Predictors in Children Under 15 Years Old Who Acquired HIV from Mother to Child Transmission in Paraguay.

We estimated mortality rate and predictors of death in children and adolescents who acquired HIV through mother-to-child transmission in Paraguay. In 2000-2014, we conducted a cohort study among children and adolescents aged < 15 years. We abstracted data from medical records and death certificates. We used the Cox proportional hazards model for the multivariable analysis of mortality predictors. A total of 302 subjects were included in the survey; 216 (71.5%) were younger than 5 years, 148 (51.0%) were male, and 214 (70.9%) resided in the Asunción metropolitan area. There were 52 (17.2%) deaths, resulting in an overall mortality rate of 2.06 deaths per 100 person-years. The children and adolescents with hemoglobin levels ≤ 9 g/dL at baseline had a 2-times higher hazard of death compared with those who had levels > 9 g/dL (HR 2.27, 95% CI 1.01-5.10). The mortality of HIV-infected children and adolescents in Paraguay is high, and anemia is associated with mortality. Improving prenatal screening to find cases earlier and improving pediatric follow-up are needed.

[Epidemiological characteristics of HIV infection in Paraguay during 2015]. / Características epidemiológicas de la infección por VIH en Paraguay durante el año 2015.

To characterize the epidemiology of HIV in Paraguay, from january to december, in 2015. The epidemic remains focused in those groups under risk, predominantly male. The characteristics of the study population shows that most of the affected were from the central area and from the capital city, and sexual transmission remains the most common pathway, with delayed diagnosis, which is reflected by the percentage of people presenting a low CD4 cell count.
