Methods This ecological-type epidemiological study analyzed data from the Health Ministries of both countries. The analysis included frequency measures, spatial autocorrelation, RR cluster analysis and map construction. Results A hyperendemic occurrence was identified in all study regions, in the state of Paraná 71.2% of the municipalities were hyperendemic and in Misiones, Argentina 41.2%. The GI* statistical analysis showed clusters of high incidence rates in the state of Paraná and low-risk clusters in much of the state of Rio Grande do Sul, both in Brazil. The analysis indicated an area with RR equal to 3.87 - (p < .0001) when considering the entire territory and an RR of 2.80 - (p < .0001) excluding the state of Paraná, with the number of departments of Misiones, Argentina included in...

During the study, one or more enteropathogens were identified in 73.9% of samples in children from Zaiman and in 58.3% of the samples from Las Dolores, being associated to diarrhoea in 70.5% and to asymptomatic infections in 65.7%. The number of diarrheic episodes was higher in Zaiman (15.45%) than in Las Dolores (12.35%), being more frequent in the spring-summer seasons. In Zaiman, the bacterial enteropathogen proportion was relevantly higher (p< 0.005) in children with diarrhoea, whereas the presence of parasites was more frequent in asymptomatic children (p< 0.01). Rotavirus had an even distribution within diarrheic and asymptomatic children. In Las Dolores, no relevant differences were found in the ...

O estudo compreendeu a Província de Misiones naArgentina e a Região Sul do Brasil. A população foi composta por 10.319 casos novos de hanseníase,diagnosticados entre 2010 e 2016.Resultados: o estado do Paraná foi o mais endêmico, representando 70,2% (n=7,247) doscasos. Houve predomínio da classificação operacional multibacilar (79,8%, n=8.233) e Grau 0de incapacidade física (50,6%, n=5.223). Em Misiones 18,9% utilizaram esquema de tratamentosubstitutivo. No período, notou-se uma situação hiperendêmica em 780 (65,5%) dos municípios/departamentos estudados.Conclusão: o estudo mostrou que as regiões estudadas apresentam alta endemicidade, transmissãoativa e diagnóstico tardio da hanseníase. Essas tendências entrelaçadas à força de morbidade e detransmissão recente e persistente da doença, ampli...

The urbanization of zoonotic visceral leishmaniasis (VL) has been observed in different South American countries, due to changes in demographic and ecological factors. In May 2006, VL was detected for the first time in the city of Posadas (Misiones, Argentina). This event encouraged us to conduct a clinical and parasitological pilot survey on domestic dogs from Posadas to identify their potential role as reservoirs for the disease. Methods: One hundred and ten dogs from the city of Posadas were included in the study. They were selected based on convenience and availability. All dogs underwent clinical examination. Symptomatology related to canine leishmaniasis was recorded, and peripheral blood and lymph node aspirates were collected. Anti-Leishmania antibodies were detected using rK39-immunocromatographic tests and IFAT. Parasite detection was based on peripheral blood an...

La sifilis transmitida de la madre al hijo fue la primera infeccion congenita reconocida y, hasta hace pocas decadas, la unica enfermedad transmitida por contacto sexual que afectaba al feto. La Organizacion Mundial de la Salud (OMS) destaca la amenaza importante que significa para la infancia, ya que si no es diagnosticada precozmente y tratada de forma adecuada puede tener consecuencias devastadoras para el nino. En Misiones, provincia de Argentina, la sifilis congenita es desde hace mas de una decada, una de las enfermedades de notificacion medica obligatoria denunciada con mayor frecuencia al Sistema Nacional de Vigilancia Epidemiologica (SINAVE) de Argentina. El Servicio de Neonatologia del Hospital Central Ramon Madariaga (HCRM) de la ciudad de Posadas en el Departamento Capital de Misiones registra el mayor numero de ingresos ...

The domestic dog is the main reservoir of zoonotic VL and a high prevalence of canine leishmaniasis (CanL) is associated with transmission of infection to humans. Here we describe the methodology used to obtain a rapid and representative sample of domestic dogs in the city of Posadas, Misiones, and compare the prevalence of Leishmania infection with a sample of shelter dogs.Methodology: We used the city land registry to make a random selection of homes and systematically recruited 349 domestic dogs from the selected properties. We also included all dogs from the main canine shelter within the city. Dogs were examined by two experienced veterinarians who recorded the presence of clinical signs common in CanL using a standardized protocol. We extracted a blood sample from each dog and performed four different serological tests to reveal the presence of anti-Leishmania antibodies.Resul...

Syphilis was confirmed in 26 (2.1%) women, and 15 cases (57.7%) of congenital syphilis were demonstrated in newborns one of whom was a stillborn. Of the syphilitic women 61.5% were 20 years old (average), 65.4% were single, 19.2% had a stable partner and 15.4% were married; 70% of them had finished elementary school (seven years), but despite this discrete level of instruction and that they were benefited with free health attention, 73% of them had not started or completed the pregnancy control. None of these women acted as sexual workers or were drug users; 57.7% were unemployed and the remainder worked as domestic servants or were still going to school. Menarca started at 13 (average) and the age of the first sexual activity was 15 (average). The distribution of the cases of syphilis within the city area shows four clusters that coincide ...

The urbanization of ZVL has been observed in different countries around the world, and there are a growing number of reports drawing attention to the emergence of this infection in new locations, as well as its increase in previously established areas of endemicity. In the city of Posadas, Misiones province, Northeastern Argentina, the transmission of ZVL associated with canines and Lutzomyia longipalpis was first reported in 2006. In the city of Puerto Iguazú, also in Misiones province, the first human case of ZVL was reported in February 2014. From 209 surveyed dogs, 15 (7.17%) were identified as positive by serological and/or parasitological methods. Amplification was observed in 14 samples and in all cases the species implicated was Leishmania infantum. To the authors’ knowledge, this is the first molecular characterization of L. infantum from dogs in this area.
