Zoonotic Sporotrichosis outbreak: Emerging public health threat in the Amazon State, Brazil.

BACKGROUND: Sporotrichosis is the most common subcutaneous mycosis caused by Sporothrix spp. Traditionally, it is transmitted through injuries involving plant debris. However, over the past few decades, there has been an epidemic increase in human cases resulting from contact with infected animals, particularly cats, in various regions of Brazil. In this report, we report a notable increase in both human and animal cases within the Brazilian Amazon state. METHODOLOGY/PRINCIPAL FINDINGS: An ecological study was conducted by analyzing official records of human and animal sporotrichosis diagnosed in the state of Amazon from 2020 to 2023. Data including patient demographics, clinical manifestations, mycological examination results, and species identification through PCR confirmation were evaluated. During this period, a total of 950 human cases and 2,823 animal cases of sporotrichosis were reported at an exponential rate, since no human cases were registered in 2020. The spatial and temporal dispersion of human sporotrichosis followed that of animal cases, moving from downtown areas to the periphery. Contact with infected animals was reported in 77.7% of cases, with cats being the most commonly implicated (73.5%). Only 66.7% of individuals underwent mycological examination. Among the positive cultures for Sporothrix spp., 65.4% were identified as S. brasiliensis. All patients were treated with systemic antifungals. CONCLUSIONS/SIGNIFICANCE: This study highlights a rising incidence of sporotrichosis among animals and humans in the Brazilian Amazon region over the past four years, with S. brasiliensis being the predominant agent. Collaborative efforts involving healthcare professionals, veterinarians, and public health authorities are crucial to implement effective control measures, educate populations at risk, and promote responsible guidance for pet guardians. These measures are essential to mitigate the burden of epidemic sporotrichosis in Brazil.

Leprosy among schoolchildren in the Amazon region: A cross-sectional study of active search and possible source of infection by contact tracing.

BACKGROUND: The high rate of leprosy cases among children under 15 years of age in Brazil indicates ongoing transmission within the community. The identification of the new leprosy cases among contacts can help identify the source of infection and interrupt the transmission chain. This study aims to determine the detection rate of previously undiagnosed cases of leprosy among schoolchildren who are under 15 years of age living in Manaus, Amazonas, Brazil, and their possible source of infection by contact tracing. METHODOLOGY/PRINCIPAL FINDINGS: This was a school-based, cross-sectional study in which the identification of active leprosy cases was conducted in 277 out of 622 randomly selected public schools in Manaus, Amazonas, Brazil. Suspected cases of leprosy were referred to the Alfredo da Matta Foundation, a reference center for leprosy in Manaus. A total of 34,547 schoolchildren were examined, and 40 new leprosy cases were diagnosed. Among new cases, 57.5% were males, and 80.0% demonstrated paucibacillary leprosy. A total of 196 of 206 registered contacts were screened, and 52.5% of the newly diagnosed children's cases had at least one positive household contact. In these contacts, grandparents (52.4%) were the most common co-prevalent cases, while 14.3% were uncles, 9.5% were parents and 9.5% were granduncles. Seven contacts (5.0%), including four siblings of child patients were newly diagnosed. Our data indicate that the prevalence is 11.58 per 10,000, which is 17 times higher than the registered rate. CONCLUSIONS/SIGNIFICANCE: This study suggests that the detection rate of leprosy among schoolchildren may have remained unchanged over the past thirty years. It also indicates that that active case finding is necessary for reaching the World Health Organization's goals of zero detection among children, especially in endemic areas where the prevalence of leprosy is obscure. Moreover, we assert that all children must have their household contacts examined in order to identify the possible source of infection and interrupt the disease's transmission. Novel strategies to reinforce contact tracing associated with large-scale strategies of chemo- and immune-prophylaxis should be expanded to prevent the perpetuation of the disease cycle.

A historical overview of leprosy epidemiology and control activities in Amazonas, Brazil.

Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC), which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

Leprosy decline in Amazonas State, Brazil.

OBJECTIVE: To analyse the leprosy case detection rates in Amazonas State, Brazil, by age group from 1980 to 2009. METHOD: The historical data series of leprosy cases by age group from 1980 to 2009 were fitted as a function of time using Poisson regression models. Relative annual reduction in the detection rate (RAR) by age group was estimated as one minus the exponential of the estimated regression coefficient for time. To compare the regression coefficients, we used their 95% confidence interval. RESULTS: The relative annual reduction varied from 9% in the age group of 0-4 years to 1% in the age group of 60-69 years. There was a declining trend of the RAR in the younger age groups that disappeared after 29 years of age. The detection rate in people >29 years old declined very little over time, with no statistically significant difference between age groups. CONCLUSION: Our findings show a reduction in the infection risk in the last 30 years and a birth cohort effect: cohorts born in more recent years faced smaller risks of leprosy infection than older cohorts.

Nosological profile in a dermatology referral center in the state of Amazonas -Brazil.

BACKGROUNDS: Fundaments: Skin diseases are associated wih high morbidity, low mortality and low rate of hospitalization. However, they can cause considerable interference in physical and emotional well-being of the individual. Several of them reach large population, requiring specific interventions for their control. OBJECTIVE: To describe the frequency of skin disease diagnosed in the dermatology service in Manaus, capital of Amazonas State. METHODS: We collected data on registered sex, age, origin and diagnostics for the first consultation of patients attended between January 2000 and December 2007. RESULTS: Of the 56.024 recorded visits, we obtained 56.720 cases of dermatological diagnoses, being the most common sexually transmitted diseases (25,12%), allergic skin disesases (14,03%), unspecified dermatoses (13,01%), leprosy (6,34%) and acne, seborrhea and related diseases (5,05%). The frequency was similar for both sexes, aged 20-29 years predominated and Manaus the origin most reported. CONCLUSIONS: The pattern of skin diseases identified in this study may serve as a baseline to managers of health system in the region develop strategies for prevention and control of dermatoses, with emphasis on sexually transmitted diseases, allergic skin diseases, leprosy and acne.

Perfil nosológico de centro de referência em dermatologia no estado do Amazonas - Brasil / Nosological profile in a dermatology referral center in the state of Amazonas -Brazil

FUNDAMENTOS: As doenças de pele estão associadas a alta morbidade, baixa mortalidade e baixa proporção de hospitalização. Entretanto, podem causar considerável interferência no bem-estar físico e emocional do indivíduo. Várias delas atingem grandes contingentes populacionais, havendo necessidade de intervenções específicas para seu controle. OBJETIVO: Descrever a frequência das dermatoses diagnosticadas em serviço de dermatologia na cidade de Manaus, capital do estado do Amazonas. MÉTODOS: Coletaram-se dados registrados sobre sexo, idade, procedência e diagnósticos referentes à primeira consulta dos pacientes atendidos entre janeiro de 2000 e dezembro de 2007. RESULTADOS: Das 56.024 consultas registradas, obtiveram-se 56.720 diagnósticos dermatológicos, sendo mais comuns as doenças sexualmente transmissíveis (25,12 por cento), as dermatoses alérgicas (14,03 por cento), as dermatoses não especificadas (13,01 por cento), a hanseníase (6,34 por cento) e acne, seborreia e afins (5,05 por cento). A frequência foi semelhante para ambos os sexos, a faixa etária de 20-29 anos foi predominante e Manaus foi a procedência mais referida. CONCLUSÕES: O padrão das doenças cutâneas identificadas neste estudo pode servir como linha de base para que gestores do sistema de saúde da região desenvolvam estratégias de prevenção e controle das dermatoses mais comuns, com ênfase nas doenças sexualmente transmissíveis, doenças cutâneas alérgicas, hanseníase e acne.

DST e suas determinantes: quatro anos de vigilância em um centro sentinela no estado do Amazonas - Brasil / Sexually transmitted diseases and its determinants: four years of sentinel surveillance in a medical center in the state of Amazonas - Brazil

Introdução: apesar da enorme magnitude e transcendência, a informação disponível sobre as DST diferentes do HIV/aids é muito limitada na maior parte dos países, por isso há necessidade de buscar informações em centros sentinelas de vigilância ou obtê-las mediante inquéritos de prevalência. Apresenta--se a experiência de 4 anos de um centro sentinela de vigilância epidemiológica. Objetivo: descrever o perfil epidemiológico das principais doenças sexualmente transmissíveis em um serviço especializado. Métodos: estudo de corte transversal com componente analítico utilizando dados secundários da base SIVADST. O estudo incluiu 14.338 pessoas que foram atendidas na Fundação Alfredo da Matta entre 2005-2008, e avaliadas utilizando-se a abordagem sindrômica e etiológica para nove das DST mais frequentes. Os diagnósticos de condiloma acuminado e herpes genital foram realizados mediante exame clínico. Todos realizaram teste de VDRL e foi oferecido o teste para HIV. Resultados: receberam diagnóstico de pelo menos uma DST, 9.346 indivíduos.Os homens predominaram (58,5%). O condiloma foi a DST mais frequente (41,2%) e as virais representaram 73%. As tendências foram descendentes paragonorreia, cancro mole e tricomoníase; estável para sífilis, condiloma e herpes e incrementou-se para HIV. Os preditores principais foram: adolescência,ser homem, pele parda e não residir em Manaus. Conclusão: destaca-se a importância de investir nestas atividades, para se dispor de informação confiável sobre a situação das DST, da carga que elas representam para os serviços de saúde e necessidades de resposta para sua prevenção e controle.

Introduction: although they achieve enormous magnitude and transcendence, the information about STD other than HIV/aids available is very limited in most countries, so, one needs to seek information in sentinel surveillance centers or get them through prevalence surveys. Presents the experience of 4 years of a sentinel surveillance center. Objective: the aim of this study was to describe the epidemiological profile of the main sexually transmitted diseases in a sentinel surveillance center. Methods: cross-sectional study using a secondary analytical component of the database SIVADST. The study included 14,338 people who were seen at Fundação Alfredo da Matta between 2005-2008, and evaluated using the syndromic approach to etiology and to the nine most common STD. The diagnosis of genital warts and genital herpes were performed by clinical examination. All patients underwent testing VDRL and HIVtesting was offered. Results: 9,346 individuals were diagnosed with at least one STD. Men predominated (58.5%). Genital warts were the most commonSTD (41.2%) and viral infections accounted for 73%. The trend was downward for gonorrhea, chancroid and trichomoniasis; stable for syphilis, herpes andwarts and increased to HIV. The main predictors were: adolescence, being male, brown skin and not residing in Manaus. Conclusion: the study highlights the importance of investing these activities, to have reliable information about STD, the load they present to health services and needs in response to its prevention and control.

Prevalência da infecção por clamídia e gonococo em mulheres atendidas na clínica de DST da fundação Alfredo da Matta, Manaus, Amazonas / Prevalence of chlamydia and gonococcal infection in women assisted in the STI clinic of Alfredo da Matta foundation, Manaus, Amazon

A pouca correspondência entre a queixa de corrimento vaginal ou cervical e a positividade da infecção gonocócica ou por clamídia tem sido amplamente divulgada na literatura, por isso é necessário continuar buscando novos elementos que permitam melhorar o seu diagnóstico. Objetivo: estimara prevalência e os fatores de risco associados à infecção gonocócica e por clamídia em população feminina sintomática ou não, atendida por demanda espontânea em uma clínica especializada em DST, e avaliar a utilidade do emprego da definição, atualmente em uso no Brasil, para escore de risco emmulheres com corrimento vaginal. Métodos: foram incluídas 239 mulheres, atendidas na clínica de DST da Fundação Alfredo da Matta, na cidade deManaus, Amazonas, em 2008, e que realizaram exames para clamídia e gonorreia. Resultados: a prevalência por clamídia e gonococo foi de 18,4% e acoinfecção, de 12,9%; a prevalência da infecção por clamídia (captura híbrida) foi de 13,0% e a de cervicite gonocócica (Thayer Martin), 7,1%. As maiores prevalências foram encontradas entre adolescentes e mulheres com antecedentes de ter parceiro com corrimento uretral, porém só a última foi um preditorsignificativo na análise multivariada para a infecção gonocócica [OR = 4,8 (2,2-10,5)]. As mulheres com corrimento e escore de risco positivo (> 2) tiveram prevalência significativamente maior só para infecção gonocócica (p < 0,001). Os resultados de sensibilidade, especificidade e VPP para a definição de risco tiveram valores baixos e não conseguiram evitar uma elevada taxa de tratamentos desnecessários. Conclusão: a infecção cervical por clamídia foi a mais frequente e dentre as pacientes, 58% eram assintomáticas. Ter parceiro com corrimento uretral foi a única variável independente significativa para infecção gonocócica e para aquelas com coinfecção, porém não foi para infecção somente por clamídia. A definição atual do escore de risco tem sensibilidade eespecificidade muito baixas para o diagnóstico de infecção cervical por clamídia, gonorreia ou ambas.

The weak correspondence between the syndrome of vaginal or cervical discharge and gonococcal or chlamydial infection has been widely reported. Therefore it is necessary to find new elements permitting to improve the diagnostic. Objectives: to estimate prevalence and risk factors associated with gonococcal and chlamydial infection in symptomatic and asymptomatic women who sought care in a STI clinic and to evaluate the performance of risk assessment score for vaginal discharge, actually used in Brazil. Methodology: in 2008, 239 women, symptomatic and asymptomatic for vaginal discharge,were recruited in the STI clinic of Fundação Alfredo da Matta in Manaus, State of Amazon, and tested for Chlamydia trachomatis e Neisseria gonorrhoeae.Results: prevalence for chlamydial infection (DNA hybridization) was 13.0%, for gonococcal cervical infection 7.1% (Thayer Martin), for coinfection12.9% and 18.4% to have either one of them. Highest prevalence were found in adolescents and women who had a partner presenting urethral dischargein the past, this being the only significant predictor in multivariate analysis for gonococcal infection [OR = 4.8 (2.2-10.5)]. Symptomatic women with apositive risk score (> 2) showed only significantly higher prevalence for gonococcal infection (p < 0.001). Evaluation of sensibility, specificity and PPV for the Brazilian risk assessment score showed low values and therefore not contribute to decrease the proportion of unnecessary treatments. Conclusion:chlamydia is the most prevalent infection among the women seeking for care at the STI clinic, and 58% of them were asymptomatic cases. Having a partner with urethral discharge represents the only independent variable for gonococcal infection or for those with coinfection, but not specifically for chlamydial infection. The risk assessment score showed insufficient sensitivity and specificity to detect cervical infection with chlamydia and gonorrhea or both.

Desigualdade social, crescimento urbano e hanseníase em Manaus: abordagem espacial / Desigualdad social, crecimiento urbano y hanseníasis en Manaus (Norte de Brasil): abordaje espacial / Social inequality, urban growth and leprosy in Manaus: a spatial approach

OBJETIVO: Analisar a epidemiologia de hanseníase segundo a distribuição espacial e condições de vida da população. MÉTODOS: Estudo ecológico baseado na espacialização da hanseníase em Manaus (AM), entre 1998 e 2004. Os 4.104 casos obtidos do Sistema de Informações de Agravos de Notificação foram georreferenciados de acordo com a localização dos endereços em 1.536 setores censitários urbanos, por meio de quatro técnicas: correios (73,7 por cento dos endereços encontrados); Programa de Cadastro de Logradouros (7,3 por cento); Programa Saúde da Família (2,1 por cento) e folhas de coleta do Instituto Brasileiro de Geografia e Estatística (1,5 por cento). Para cálculo do coeficiente de detecção utilizou a população de 2001. Na análise espacial foi aplicado o método bayesiano empírico local para produzir uma estimativa do risco da hanseníase, suavizando o efeito da flutuação das taxas, quando calculadas para pequenas áreas. Para análise da associação entre espacialização e fatores de risco empregou-se a regressão logística, tendo como variáveis explicativas a ocorrência de casos em menores de 15 anos (indicador de gravidade) e o Índice de Carência Social construído a partir das variáveis do Censo 2000. RESULTADOS: O coeficiente de detecção apresentou-se hiperendêmico em 34,0 por cento dos setores e muito alto em 26,7 por cento. A medida de associação (odds ratio) referente às variáveis explicativas foi significativa. A combinação de baixa condição de vida e ocorrência em menores de 15 anos foi adotada para identificar as áreas prioritárias para intervenção. CONCLUSÕES: A análise espacial da hanseníase mostrou que a distribuição da doença é heterogênea, atingindo mais intensamente as regiões habitadas por grupos em situação de maior vulnerabilidade.

Social inequality, urban growth and leprosy in Manaus: a spatial approach.

OBJECTIVE: To analyze the epidemiology of leprosy according to spatial distribution and living conditions of the population. METHODS: Ecological study based on the spatial distribution of leprosy in the municipality of Manaus, Northern Brazil, from 1998 to 2004. The 4,104 cases identified in the Sistema de Informações de Agravos de Notificação (Sinan -National Notification System) were georeferenced according to the addresses in the 1,536 urban census tracts through four different sources: postal service (73.7% of addresses found), Property Registration Program (7.3%), Family Health Program (2.1%), and Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics) data sheet (1.5%). Calculation of detection coefficient was performed based on the 2001 population. Local empirical Bayesian method was used for the spatial distribution analysis, in order to estimate leprosy risk, making rate variation shorter when they were calculated for small areas. Logistic regression was employed to analyze the association between geographical distribution and risk factors. The incidence of cases in children under 15 (severity indicator) and Social Need Index built from variables of the 2000 census were adopted as explicative variables. RESULTS: The mean coefficient of detection was hyperendemic in 34.0% of the census tracts, and very high in 26.7%. Odds ratio was obtained for explicative variables and proved to be significant. Low-income and incidence in children under 15 were combined to identify priority areas for intervention. CONCLUSIONS: Spatial analysis of leprosy showed that the distribution of the disease is heterogeneous and is more strongly present in regions inhabited by more vulnerable groups.

Perfil epidemiológico da hanseníase em menores de quinze anos de idade, Manaus (AM), 1998-2005 / Perfil epidemiológico de la hanseniasis en menores de quince años de edad, Manaus (Norte de Brasil), 1998-2005 / Epidemiological profile of leprosy in children under 15 in Manaus (Northern Brazil), 1998-2005

OBJETIVO: Analisar a situação epidemiológica da hanseníase em crianças, em zona urbana. MÉTODOS: Foram estudados 474 casos de hanseníase, em menores de 15 anos, detectados na zona urbana de Manaus (AM), de 1998 a 2005. A partir dos dados do Sistema de Informações de Agravos de Notificação foram analisados o perfil da endemia e a qualidade do atendimento nos serviços de saúde, utilizando os indicadores epidemiológicos e operacionais Programa Nacional de Eliminação da Hanseníase. RESULTADOS: Os casos de hanseníase em menores de 15 anos corresponderam a 10,4 por cento do total de casos detectados no período. O coeficiente de detecção nessa faixa etária manteve-se no nível hiperendêmico entre 1998 e 2003, reduzindo a partir do ano de 2004 mas mantendo endemicidade muito alta. A forma clínica mais freqüente foi a tuberculóide, seguida da dimorfa. As formas paucibacilares corresponderam a 70,7 por cento dos casos e no momento do diagnóstico, o grau de incapacidades foi avaliado em 94,7 por cento dos pacientes, dos quais 2,9 por cento apresentaram incapacidades físicas. A maioria dos casos (99,4 por cento) foi tratada com o esquema poliquimioterápico da Organização Mundial da Saúde. CONCLUSÕES: Apesar de seu decréscimo, o coeficiente de detecção da hanseníase nas crianças em Manaus mantém nível de endemicidade muito alto.

Epidemiological profile of leprosy in children under 15 in Manaus (Northern Brazil), 1998-2005.

OBJECTIVE: To describe the epidemiological status of leprosy in children living in a metropolitan area. METHODS: There were studied 474 leprosy cases detected in children under 15 living in the metropolitan area of the city of Manaus, Northern Brazil, between 1998 and 2005. The endemic profile and quality of care services were assessed based on data from the Notifiable Diseases Information System using epidemiological and operational indicators of the National Leprosy Elimination Program. RESULTS: Of all leprosy cases detected in the period studied, 10.4% were found in children under 15. The detection rates in this age group remained at hyperendemic levels between 1998 and 2003, and decreased from 2004 onwards but keeping on very high endemic levels. The most common clinical form was tuberculoid followed by dimorphous. Paucibacillary forms were seen in 70.7% of the cases. The level of disability at the time of diagnosis was assessed in 94.7% of patients and 2.9% of them had physical disabilities. Most children (99.4%) were treated with the multiple drug regimen recommended by the World Health Organization. CONCLUSIONS: Despite its decrease, detection rate of leprosy in children in the city of Manaus remains at a very high endemic level.

Intervenção de base comunitária para a prevenção das DST/Aids na região amazônica, Brasil / Community-based intervention to control STD/AIDS in the Amazon region, Brazil / Community-based intervention to control STD/AIDS in the Amazon region, Brazil

OBJETIVO: Descrever estudo de caso de intervenção de base comunitária, desenvolvido na perspectiva construcionista-emancipatória, para o controle das DST/Aids. MÉTODOS: Estudo descritivo desenvolvido no município de Manacapuru, Amazonas, de 1997-2004, sobre a utilização de procedimentos desenhados em colaboração com agentes governamentais, profissionais de saúde e comunidade. Foram levantados dados sobre a dinâmica da prostituição e a venda de preservativos na cidade, características comportamentais, avaliação do processo e da assistência às DST/Aids. Sincronicamente, estabeleceram-se ações de prevenção e assistência na rede pública de saúde às DST, centro de testagem, sistema de vigilância epidemiológica, e capacitação de trabalhadoras do sexo. RESULTADOS: Observou-se o fortalecimento das trabalhadoras do sexo como multiplicadoras e sua legitimação como cidadãs e agentes de saúde em projetos com travestis, homossexuais e escolares. Houve incremento da venda de preservativos na cidade, da utilização de preservativos entre trabalhadoras do sexo, redução das DST bacterianas e estabilização da ocorrência de infecção pelo HIV/Aids e sífilis congênita. A sustentabilidade do programa de intervenção estudado, organizado no âmbito do Sistema Único de Saude, foi estimulada pela pactuação política garantindo sede e orçamento regulamentado em lei municipal, e pelo debate permanente dos resultados do processo e programa. CONCLUSÕES: O estudo fortaleceu a noção de que o controle efetivo das DST/Aids depende de uma abordagem sinérgica que combine intervenções no plano individual (biológica-comportamental), sociocultural e programático.

OBJECTIVE: To describe a case study of community-based intervention, developed in a constructionist-emancipatory framework to control STD/AIDS. METHODS: Descriptive study developed in the town of Manacapuru, in the state of Amazonas, from 1997 to 2004, focusing on procedures designed in collaboration with government agents, health professionals and the community. Data on the dynamics of prostitution and condom sales in this town, preventive practices and STD/AIDS care and process assessment were collected. Actions targeting STD prevention and care in the public healthcare system, a testing center, an epidemiological surveillance system and sex workers' qualification were established concomitantly. RESULTS: It was observed the strengthening of sex workers as peer educators and their legitimization as citizens and health agents in projects involving transvestites, homosexuals and students. There was an increase in condom sales in town, as well as in condom use among sex workers; reduction in bacterial STD; and stabilization of the incidence of HIV/AIDS infections and congenital syphilis. The sustainability of the intervention program studied, organized within the sphere of action of the Sistema Único de Saúde (National Health System), was promoted by a political pact, which guaranteed headquarters and municipal law-regulated budget, as well as by the constant debate over the process and program results. CONCLUSIONS: The study strengthened the notion that effective control of STD/AIDS depends on a synergic approach that combines interventions on individual (biological-behavioral), sociocultural and programmatic levels.
