INTRODUCTION: Abdominal and neural angiostrongyliasis caused by Angiostrongylus costaricensis and A. cantonensis, respectively, are zoonotic diseases involving snails as intermediate hosts. Colombia has already reported human cases, and the increasing distribution of Lissachatina fulica and Cornu aspersum raises public health concerns due to the potential risk of disease transmission in areas where parasites and hosts coexist. OBJECTIVE: To identify the presence of Angiostrongylus spp. in snail species L. fulica and C. aspersum in Antioquia, Colombia. MATERIALS AND METHODS: This prospective cross-sectional study had a population of 5,855 L. fulica and C. aspersum snails captured in the ten towns of the Valle de Aburrá (Antioquia, Colombia), 169 samples were collected in 28 sampling points. Lung tissues of the collected snails were dissected and analyzed to detect Angiostrongylus spp. through molecular techniques. RESULTS: Angiostrongylus spp. were identified in both L. fulica and C. aspersum. Angiostrongylus costaricensis was detected in 18 pooled prevalence of 30% (95% CI = 19.2-43.3), and Medellín was the municipality with the highest number of positive samples (33.3%). Seventy-two-point-two percent of the positive places reported the presence of rodents. None of the tests were positive for A. cantonensis. CONCLUSION: Our findings provide important insights into the epidemiology and distribution of Angiostrongylus spp. in Antioquia, Colombia. The identification of these parasitic nematodes in L. fulica and C. aspersum highlights the potential role of these snails as intermediate hosts in the transmission of Angiostrongylus spp. infections in the Valle de Aburrá, with implications for human and veterinary health.

INTRODUCTION: Postpartum anxiety after childbirth is a common condition among pregnant women due to reasons such as the uncertainty of experiencing pregnancy and childbirth for the first time, or previous negative experiences. Fear of childbirth can affect the mother's baby care process. OBJECTIVE: This study was conducted analytically with a single-subject design to determine the effects of maternal concerns about childbirth and the postpartum period on obsessive and compulsive behaviors related to baby care. MATERIALS AND METHODS: The study was conducted with 260 mothers. Data were collected using a descriptive information form, and the scales 'Fear of Childbirth and Postpartum Period', and 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care'. The data were analyzed using the SPSS™ software to calculate percentages, mean values, t tests, ANOVA, Pearson's correlation, and simple linear regression analysis. RESULTS: A statistically significant and positive correlation was found between participant scores of the 'Fear of Childbirth and Postpartum Period' and the 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care' scales (p < 0.01). The regression model showed that 18.0% of the total variance in the obsessive and compulsive behaviors of mothers in the postpartum was explained by the fear of childbirth and the postpartum period (corrected R2 = 0.180). CONCLUSIONS: Fear of childbirth and the postpartum period were moderate. However, as the fear of women regarding childbirth and the postpartum period increased, their postpartum obsessive and compulsive behaviors about baby care also increased.

INTRODUCTION: Due to the cross-reactivity between SARS-CoV-2 and common human coronaviruses, previous infections with these viruses could contribute to serological or cellular cross-protection against severe COVID-19. However, protective immunity may not develop, or pre-existing immunity could increase COVID-19 severity. OBJECTIVE: To determine the seroprevalence of IgG antibodies against HCoV-NL63 and HCoV-HKU1 and correlate previous exposure with COVID-19 signs in patients from Villavicencio. MATERIALS AND METHODS: A cross-sectional retrospective study was conducted. ELISA technique was used to search for IgG antibodies against HCoV-NL3 and HCoV-HKU1 in patients with positive RT-qPCR results for SARS-CoV-2. Patients were grouped according to COVID-19 clinical characteristics in four groups: group 1: asymptomatic (n = 23); group 2: hospitalized (n = 24); group 3: intensive care units (n = 24), and group 4: dead (n = 22). RESULTS: The overall seroprevalence of IgG antibodies against HCoV was 74.2% (n = 69; 95% CI: 65.3-83.1), with 66.7% of HCoV-NL63 (n = 62; 95% CI: 57,1-76,2), and 25.8% of HCoV-HKU1 (n = 24; 95% CI: 16,9-34,7). Based on crosstab analysis, prior exposure to HCoV-NL63 was associated with protection against severe COVID-19 (p = 0.042; adjusted OR = 0.159; 95% CI: 0.027-0.938), and previous coinfection of HCoV-NL63 and HCoVHKU1 was considered a positive association to severe COVID-19 (p = 0.048; adjusted OR = 16.704; 95% CI: 1.020 - 273.670). CONCLUSION: To our knowledge, this is the first study addressing seroprevalence of HCoV IgG antibodies in Colombia and Latin America. Previous exposure to HCoV-NL63 could protect against severe COVID-19, whereas patients with underlying HCoV-NL63 and HCoVHKU1 coinfection could be hospitalized with severe signs of COVID-19.

Introduction. Proper management of multidrug-resistant tuberculosis is a prioritized strategy for tuberculosis control worldwide. Objective. To evaluate differences concerning demographic and clinical characteristics and programmatic indicators of Buenaventura patient cohort with confirmed diagnosis of multidrug-resistant tuberculosis, compared to those of the other municipalities from Valle del Cauca, Colombia, 2013-2016. Materials and methods. We conducted an analytical cohort study to compare records of patients older than 15 years with multidrug-resistant tuberculosis included in the Programa de Tuberculosis de Buenaventura (with para-aminosalicylic acid) versus the other municipalities of Valle del Cauca (without para-aminosalicylic). Results. Ninety-nine cases were recorded with a median age of 40 years (IQR = 26 - 53); in Buenaventura, 56% of the patients were women, while in the other municipalities, men predominated with 67%; 95% had health insurance. The most common comorbidity was diabetes (14%). Adverse reactions to antituberculosis medications in Buenaventura were 1.3 times more frequent than in the other municipalities (OR = 2.3; 95% CI = 0.993 - 5.568; p = 0.04). In Buenaventura, the mortality rate was 5% compared to the 15% reported in the other municipalities. Treatment failures were not reported in Buenaventura, but 35% did not continue with the follow-up. Treatment success was higher in Buenaventura (56 %). Conclusion. A strengthened program in Buenaventura presented better programmatic results than those from the other municipalities of Valle del Cauca. Access to molecular tests, availability of shortened treatments, and continuous monitoring to identify adverse reactions to antituberculosis medications are routes for all other control programs.

INTRODUCTION: Air quality is a matter of interest for public health due to its rapid deterioration in low- and middle-income countries and the effects of polluted air on the health of populations. OBJECTIVE: To explore the air quality conditions in which digital platform delivery workers carry out their work, evaluating the localities of Kennedy and Usaquén in Bogotá, 2021. MATERIALS AND METHODS: We developed a mixed parallel convergent study based on four sources of information: 1) Ethnographic observation in five commercial locations of the two localities; 2) Monitoring of PM10 and PM2.5 in 56 delivery routes using a low-cost sensor; 3) Daily logs of the routes to support the device data interpretation, and 4) A semi-structured interview applied to the drivers to explore their danger perception during the routes. RESULTS: We identified elements causing environmental injustice among digital platform delivery workers between the two study locations. The routes made by the delivery drivers in the locality of Kennedy registered higher concentrations of PM10 and PM2.5, compared to the values observed in Usaquén. The sources of air pollution identified by the delivery drivers through ethnographic observation and the router logbook showed the worst parameters in Kennedy. CONCLUSIONS: We evidenced that air quality, urban equipment, road infrastructure, mobile sources, and geospatial location are elements that mark the presence of environmental injustice for the digital platform delivery drivers in the studied localities. To reduce this inequity, it is necessary for digital delivery platforms and the district government to implement strategies that reduce the exposure and emission of air pollutants to protect the health of digital platform delivery workers.

INTRODUCTION: Data on the prevalence of fungal coinfections/superinfections in patients with COVID-19 are limited. OBJECTIVE: To describe the prevalence of fungal coinfections/superinfections in patients with COVID-19, as well as risk factors and demographic, clinical, and microbiological characteristics. MATERIAL AND METHODS: We included patients with a confirmed COVID-19 diagnosis and a confirmed fungal infection hospitalized in the ICU from March 2020 to December 2021. We collected data on age, sex, comorbidities, hospital length of stay (days), laboratory (ferritin) and microbiological results, treatment for COVID-19, antifungal therapy, and outcomes obtained from the clinical records. RESULTS: Only 11 out of 740 patients met the inclusion criteria. The coinfection rate was 0.3% and the superinfection was 1.2%. The most affected population was male adults. The coinfections/superinfections diagnosed were candiduria and candidemia, caused by Candida albicans, C. tropicalis, C. glabrata, C. lusitaniae, and Kluyveromyces marxianus (C. kefyr). In addition, tracheobronchitis due to Aspergillus fumigatus was found. The most used antifungals were fluconazole and caspofungin. The lethality in patients with fungal coinfections was 50% and superinfections, 22%. The length of hospital stay was 11-65 days. Eight patients required mechanical ventilation and six received corticosteroids. The main comorbidity was diabetes mellitus (81.8%). CONCLUSIONS: The rate of fungal coinfections/superinfections in COVID-19 patients was low, but the lethality found urges for routine fungal screening in patients with severe COVID-19 to timely detect fungal infections that may further compromise the patient’s life.

The national transplant law in Colombia, Law 1805 of 2016, modified the Colombian legislation regarding how a person accesses an organ transplant, but above all, it changed the donor figure, establishing the term derived from the presumptive consent right. This term implies a person’s hypothetical willingness to be an organ donor as a manifestation of solidarity and charity towards another person in a situation of need and vulnerability concerning his/her health and the dimensions that define it. In the following text, seven moments are considered fundamental facts when constructing a culture about the value of healthcare in the national transplant policy in Colombia.

Introducción. El parto prematuro es un problema médico, social y económico importante, causa gran mortalidad y morbilidad neonatal, tiene un impacto importante en el sistema de salud y afecta la calidad de vida de las familias. El peso de los recién nacidos de madres con enfermedad periodontal es significativamente menor en comparación con los de madres no afectadas por esta enfermedad bucal. Este resultado adverso se considera un problema de salud pública global según los datos epidemiológicos. Objetivo. Determinar la asociación entre la prevalencia de parto prematuro y la enfermedad periodontal en Bolivia, Chile y Colombia entre el 2000 y el 2020. Materiales y métodos. Este estudio ecológico consideró las poblaciones de mujeres de Bolivia, Chile y Colombia, y la prevalencia de partos prematuros y enfermedad periodontal, discriminadas por grupos de edad. El estudio abarcó el período entre el 2000 y el 2020. La estrategia de búsqueda con la herramienta de investigación del Institute for Health Metrics and Evaluation incluyó prevalencia, grupos de edad, años entre 2000 y 2020, causas de parto prematuro y enfermedad periodontal, contexto y ubicaciones, mujeres y tasas. El análisis estadístico incluyó una regresión lineal simple entre parto prematuro y enfermedad periodontal para cada grupo de edad dentro de cada país. Resultados. Las tasas de partos prematuros fueron mayores en el grupo de 15 a 19 años (Bolivia: 697.563, Chile: 844.864, Colombia: 804.126). La prevalencia de la enfermedad periodontal aumentó con la edad, particularmente en el grupo de 45 a 49 años (Bolivia: 22'077.854, Chile: 34'297.901, Colombia: 32'032,830). Según los grupos de edad, la regresión lineal fue estadísticamente significativa (p < 0,001) para todos los grupos evaluados de la población boliviana, en los grupos mayores de 30 años para las colombianas y solo en el grupo de 15 a 19 años para las mujeres chilenas. Conclusión. Se encontró asociación entre el parto prematuro y la enfermedad periodontal en todos los grupos de edad en Bolivia, solo en el grupo de 15 a 19 años en Chile, y de 30 años y más en Colombia en el período evaluado de 20 años.

In Salmonella enterica serovar Typhimurium (Typhimurium), multidrug resistance is associated with integrons carrying resistance genes dispersed by mobile genetic elements. This exploratory systematic review sought to identify integron types and their resistance genes in multidrug resistance Typhimurium isolates. We used Medline, PubMed, SciELO, ScienceDirect, Redalyc, and Google Scholar as motor searchers for articles in Spanish or English published between 2012 and 2020, including the keywords “integrons”, “antibiotic resistance”, and “Salmonella Typhimurium”. We included 38 articles reporting multidrug resistance up to five antibiotic families. Class 1 integrons with aadA2 and blaPSE-1 gene cassettes were predominant, some probably related to the Salmonella genomic island 1. We did not find studies detailing class 1 and 2 integrons in the same isolate, nor class 3 integrons reported. The presence of integrons largely explains the resistance profiles found in isolates from different sources in 15 countries.

INTRODUCTION: High-grade gliomas are the most common primary brain tumors in adults, and they usually have a quick fatal course. Average survival is 18 months, mainly, because of tumor resistance to Stupp protocol. OBJECTIVE: To determine high-grade glioma patient survival and the effect of persuasion variables on survival. MATERIALS AND METHODS: We conducted a longitudinal descriptive study in which 80 untreated recently diagnosed high-grade glioma patients participated. A survey was conducted regarding their exposure to some risk factors, degree of genetic instability in peripheral blood using micronucleus quantification on binuclear lymphocytes, micronuclei in reticulocytes and sister-chromatid exchanges in lymphocytes. In the statistical analysis, this study constructed life tables, used the Kaplan-Meier, and the log-rank test, and in the multivariate analysis, a Cox proportional hazards model was constructed. RESULTS: Eighty patients' clinical, demographic and lifestyle characteristics were analyzed, as well as their survival rates and the average survival time is 784 days (interquartile range: 928). Factors like age, exposure at work to polycyclic hydrocarbons and the number of sister-chromatid exchanges in lymphocytes in the first sampling was significantly survivalrelated in the multivariate analysis. CONCLUSION: We determined that only three of the analyzed variables have an important effect on survival time when it comes to high-grade glioma patients.

Introduction. El Alférez, a village in Los Montes de María (Bolívar, Colombia) and a macro-focus of leishmaniasis, recorded its first case in 2018, evidencing changes in the distribution and eco-epidemiology of the disease, although interactions between vectors and local fauna remain unknown. Objective. To evaluate the diversity of sandflies and their blood meal sources in the community of El Alférez in the municipality of El Carmen de Bolívar (Bolívar, Colombia). Materials and methods. In 2018, sandflies were collected using LED-based light traps in domestic, peridomestic, and sylvatic ecotopes and identified at the species level. Multiplex polymerase chain reaction targeting the mitochondrial cytochrome B gene was used to analyze blood from the digestive tract. Results. Lutzomyia evansi was the most abundant species (71.85%; n = 485/675), followed by Lu. panamensis, Lu. gomezi, Lu. trinidadensis, Lu. dubitans, Lu. abonnenci, and Lu.aclydifera. Twenty-five percent of the species had blood meals from Canis familiaris (36.00%; n = 9/25), Ovis aries (36.00%; n=9:/25), Bos taurus (24.00%; n = 6/25), Sus scrofa (20.00%; n = 5/25), and Homo sapiens (8.00%; n = 2/25). Lutzomyia evansi registered the highest feeding frequency (68.00%; n = 17/25), predominantly on a single (44.00%; n = 11/25) or multiple species (24.00%; n = 6/25). Conclusion. Results indicate a eclectic feeding behavior in Lu. evansi, implying potential reservoir hosts for Leishmania spp. and increasing transmission risk. This study is a first step towards understanding the diversity of mammalian blood sources used by sandflies, that may be crucial for vector identification and formulation of effective control measures.

INTRODUCTION: Medications are a fundamental part of the treatment of multiple pathologies. However, despite their benefits, some are considered potentially inappropriate medications for older people given their safety profile. Epidemiological data differences related to potentially inappropriate medications make it difficult to determine their effects on elderly people. OBJECTIVE: To estimate the prevalence and types of potentially inappropriate medications using the 2019 Beers Criteria® in a cohort of adults older than 65 years. MATERIALS AND METHODS: We performed an observational, multicenter, retrospective, longitudinal study of a four-year follow-up of potentially inappropriate medications in community-dwelling older adults. RESULTS: We followed 820 participants from five cities for four years (2012-2016) and evaluated them in three different moments (m1 = 2012, m2 = 2014, and m3 = 2016). The average age was 69.07 years, and 50.9% were women. The potentially inappropriate medication prevalence in the participants was 40.24%. The potentially inappropriate medications' mean among the studied subjects in the first moment was 1.65 (SD = 0.963), in the second was 1.73 (SD = 1.032), and in the third was 1.62 (SD = 0.915). There were no statistical differences between measurements (Friedman test, value = 0.204). The most frequent potentially inappropriate medications categories were gastrointestinal (39.4%), analgesics (18.8%), delirium-related drugs (15.4%), benzodiazepines (15.2%), and cardiovascular (14.2%). CONCLUSIONS: About half of the population of the community-dwelling older adults had prescriptions of potentially inappropriate medications in a sustained manner and without significant variability over time. Mainly potentially inappropriate medications were gastrointestinal and cardiovascular drugs, analgesics, delirium-related drugs, and benzodiazepines.

INTRODUCTION: The gag reflex is a protection mechanism that prevents food and unwanted agents from entering the lower airways. It is usually part of the physical examination of swallowing to detect oropharyngeal dysphagia, but it is a potentially ambiguous sign. OBJECTIVE: To evaluate the diagnostic value of the gag reflex in patients with neurogenic oropharyngeal dysphagia and adults without it. MATERIALS AND METHODS: We conducted an analytical observational study in patients with neurogenic oropharyngeal dysphagia (cases) and patients without dysphagia (controls). We evaluated the absence or presence of the reflex bilaterally, by direct visualization, and adjusted it according to sex, age, and other interaction variables. RESULTS: We included 86 patients with neurogenic oropharyngeal dysphagia and 80 control subjects. The gag reflex on swallowing physical examination showed a positive relationship with the patients (right side: OR = 3.97; 95 % CI: 2.01-7.84; left side: OR = 4.84; 95 % CI: 2.41-9.72), but a negative association with the control group. In both groups, neither sex, nor age, nor other interaction variables modified the gag reflex. CONCLUSIONS: The gag reflex absence or presence does not confirm or exclude the existence of oropharyngeal dysphagia due to neurological and neuromuscular causes. Therefore, health professionals must not rely on this reflex. Clinicians must go beyond a simple reflex revision, even in neurological patients where it is supposed to be absent.

Mucormycosis is a rare fungal infection caused by fungi of the Mucorales order that occurs in immunocompromised individuals or with loss of skin or mucosa barrier integrity. This report presents four cases of rhinocerebral mucormycosis attended at a third-level hospital in Cali (Colombia) during a period of three years. All patients had different case histories and times of evolution. All four had a previous or de novo diagnosis of type 2 diabetes mellitus, with glycated hemoglobin higher than 10% on admission. We ruled out other possible pathologies that could explain their immunocompromised condition. Mucormycosis diagnosis was made with direct visualization of hyaline coenocytic hyphae on biopsies. The basis of treatment was liposomal amphotericin B and surgical debridement. Two patients presented bacterial coinfection. One asked for voluntary discharge without having completed the treatment, and another one died. The remaining two have attended controls and had an adequate evolution.

Introduction. Sexual violence against adolescents is a global problem that affects young people around the world. The ecological model examines its forms and determinants through interconnected levels. Objective. To determine the frequency, characteristics, and predictors of sexual violence in adolescents attending school in Perú. Materials and methods. This was a cross-sectional study that secondarily analyzed data from the Encuesta Nacional de Relaciones Sociales (2019). A stratified probabilistic sample involved 1,579 youth aged 12-17 from 93 schools. The questionnaire evaluated physical, psychological, and sexual violence in the family and at school. Models were estimated using logistic regression analysis, calculating odds ratio (OR). Results. Eighteen point sixty eight per cent (95% CI: 16.80-20.60) suffered some type of sexual assault. In addition, 9.75% (95% CI: 8.28-11.21) reported having been touched in some part of the body and 1.84% (95% CI: 1.17-2.50) reported that was a victim of rape. Age was identified as a risk factor in the microsystem (OR = 1.48) (95% CI: 1.26-1.74), while the age of the first experienced sexual violence acted as a protective factor (OR = 0.61) (95% CI: 0.54-0.69). In addition, in the macrosystem, the perception that violence occurs mainly outside the home increased the risk (OR = 2.06) (95% CI: 1.01-4.19). Conclusions. Approximately two out of ten respondents reported having experienced some type of sexual violence, with verbal harassment and invasive personal contact being the most common. No single level or factor can fully explain adolescent sexual violence without considering its ecological interconnectedness.

Introduction. Asthma is a chronic disease affecting millions of people around the world. Air quality is a major factor in triggering asthma symptoms. Objective. To analyze air quality and asthma in high-altitude residents of La Paz, Bolivia. Materials and methods. In this analytical, descriptive, and retrospective study, we collected data from patients diagnosed with asthma at the Instituto Nacional del Tórax and the Instituto Boliviano de Biología de Altura. In addition, air quality monitoring of particulate matter was carried out at the stations of the Red de Monitoreo de la Calidad del Aire. Results. Women represented 56.9% of cases at the Instituto Nacional del Tórax and the Instituto Boliviano de Biología de Altura. In both institutions, the average age was 47 years and patients were overweight or obese. Increases in PM2.5 were recorded in autumn, winter and spring from 2014, 2016 to 2019 and 2015 in all four seasons. PM10 showed increases in autumn and winter from 2014 to 2020 within the established limits. We observed a positive and significant association between PM2,5 concentration and the spirometry parameters of forced vital capacity, peak expiratory flow, and “reversibility percentage” or “bronchodilator response percentage”. The association of PM10 and forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow, was also statistically significant. Conclusion. Asthma cases occur on average at 47 years of age in overweight or obese people. We observed a positive association between particles PM2,5 and PM10 with spirometric parameters, stronger with particulate matter PM2,5.

INTRODUCTION: The Mycobacterium chelonae species and the M. avium and M. abscessus complexes are emerging pathogens that cause mycobacteriosis. Treatment depends on the species and subspecies identified. The drugs of choice are macrolides and aminoglycosides. However, due to the resistance identified to these drugs, determining the microbe’s sensitivity profile will allow clinicians to improve the understanding of the prognosis and evolution of these pathologies. OBJECTIVE: To describe the macrolide and aminoglycoside susceptibility profile of cultures identified by Colombia’s Laboratorio Nacional de Referencia de Mycobacteria from 2018 to 2022, as Mycobacterium avium complex, M. abscessus complex, and M. chelonae. Materials and methods. This descriptive study exposes the susceptibility profile to macrolides and aminoglycosides of cultures identified as M. avium complex, M. abscessus complex, and M. chelonae using the GenoType® NTM-DR method. MATERIALS AND METHODS: This descriptive study exposes the susceptibility profile to macrolides and aminoglycosides of cultures identified as M. avium complex, M. abscessus complex, and M. chelonae using the GenoType® NTM-DR method. RESULTS: We identified 159 (47.3 %) cultures as M. avium complex, of which 154 (96.9 %) were sensitive to macrolides, and 5 (3.1 %) were resistant; all were sensitive to aminoglycosides. From the 125 (37.2 %) cultures identified as M. abscessus complex, 68 (54.4 %) were sensitive to macrolides, 57 (45.6 %) were resistant to aminoglycosides, and just one (0.8 %) showed resistance to aminoglycosides. The 52 cultures (15.5 %) identified as M. chelonae were sensitive to macrolides and aminoglycosides. CONCLUSIONS: The three studied species of mycobacteria have the least resistance to Amikacin. Subspecies identification and their susceptibility profiles allow the establishment of appropriate treatment schemes, especially against M. abscessus.

Introduction. Colombia is home to 2 million indigenous people who live in conditions of poverty and with health deficiencies, making them vulnerable to contracting hepatitis B (HBV). Amazonas has a high virus prevalence, and there are barriers to accessing vaccination; thus, part of the population is susceptible to infection. Objective. To identify factors associated with HBV in Colombian indigenous people. Materials and Methods. A case-control study of people over 18 years from four departments of Colombia. Cases were identified through the national hepatitis B notification registry (2015-2022). Controls were selected and matched to cases (2:1) by age, sex, ethnicity, and department. Sociodemographic characteristics, factors associated with contact with body fluids, cultural practices, and vaccination history were identified by means of a survey. The ethics committee of the Universidad de Antioquia approved the project. Results. Seventy five cases and 150 controls from 13 ethnic groups were surveyed. Amazonas contributed 49% of participants, 83% were women, and the median age of cases was 30 years (IQ range: 27-37). The associated factors were a family history of hepatitis B [adjusted OR: 2.61 (95% CI: 1.09-6.27)] and, in women, the number of pregnancies [adjusted OR: 1.61 (95% CI 1.02- 2.54)]. The vaccination history showed a protective effect, but the association was not significant. Conclusion. Aspects associated with family life and unprotected sexual relations seem to be responsible for the potential transmission of the virus. It was not possible to identify associated cultural practices. Innovative and differential strategies are required for indigenous people to achieve a reduction of HBV.
