RESUMEN
INTRODUCTION: Dengue disease represents a large and growing global threat to public health, accounting for a significant burden to health systems of endemic countries. The World Health Organization's (WHO) Strategic Advisory Group of Experts (SAGE) and the European Medicines Agency (EMA) currently recommend the use of TAK-003 dengue vaccine in high dengue burden and transmission settings for countries considering vaccination as part of their integrated management strategy for prevention and control of Dengue. AREAS COVERED: This paper describes the main conclusions of a workshop held by the Arbovirus Committee of the Latin American Society of Pediatric Infectious Diseases (SLIPE) in November 2024, to generate consensus recommendations on the introduction of this new vaccine in the region. Considerations were made regarding the molecular epidemiology of dengue infection in the Americas and the need for more precise phylogenetic classification and correlation with clinical outcome and disease severity. EXPERT OPINION: Introduction of dengue vaccine should be considered as an strategy for health entities in the region, with participation of social sectors, scientific societies, and ministries of health that could be able to create a successful vaccination program.
RESUMEN
Introducción: Las desigualdades amenazan el progreso del país hacia la equidad y la cobertura de vacunación infantil. Siendo la cobertura inferior a la meta del 90% de la Organización Mundial de la Salud. Objetivo: Identificar los determinantes sociales y las desigualdades en el estado de vacunación infantil en República Dominicana, 2019. Métodos: Se realiza un análisis basado en la Encuesta de Indicadores Múltiples por Conglomerados. Incluyendo una muestra ponderada de 1674 niños de 12-23 meses. Se calcula la regresión logística multinomial para identificar factores asociados a la vacunación. Adoptando p<0,05 para significación estadística. Utilizando una razón de probabilidades ajustada con intervalo de confianza del 95%. Empleando HEAT 4.0 para medir desigualdades y SPSS.23 para gestión y análisis de datos. Resultados: La edad media de los niños fue 17,4±3,5 meses. El 33% de ellos estaban completamente vacunados. La cobertura fue significativamente menor entre hijos de madre sin educación [AOR= 7,27; IC95%= 2,9817,74]. La mayor cobertura se concentra en niños con altos niveles de educación y riqueza. Conclusión: Para lograr una cobertura de vacunación completa y equitativa, las intervenciones de salud pública deben diseñarse para satisfacer las necesidades de grupos de alto riesgo.
Introduction: In the Dominican Republic, inequalities threaten progress towards childhood vaccination equity and coverage, the latter being inferior to the World Health Organization's 90% goal. Objective: Identify the social determinants and inequalities in the state of childhood vaccination in the Dominican Republic, 2019. Methods: An analysis based on the Multiple Indicator Cluster Surveys is conducted. Including a weighted sample of 1674 children aged 12-23 months. The multinomial logistic regression is calculated to identify factors associated with vaccination. Using p<0,05 for statistical significance and an adjusted probability ratio with a 95% confidence interval. Employing HEAT 4.0 to measure inequalities and SPSS.23 for data management and analysis. Results: The children's mean age was 17,4±3,5 months. 33% of them were completely vaccinated. Coverage was significantly lower in children of mothers without education [AOR= 7,27; CI95%= 2,9817,74]. Coverage was the highest in kids with high levels of education and wealth. Conclusion: To achieve complete and equitable vaccine coverage, public health interventions should be designed to satisfy the needs of high-risk groups.

While the first 1,000 days of life are a critical period in child's development, limited information on the main determinants affecting this period in the Latin America and the Caribbean (LAC) region is available. Therefore, the Latin American Pediatric Infectious Diseases Society (SLIPE) held an ad hoc workshop in May 2022 with an expert panel designed to analyze the main factors impacting the development of childhood in the region during this period and the main causes of maternal infant morbimortality. The aim was to identify priorities, generate recommendations, and advise practical actions to improve this situation. Considerations were made about the challenges involved in bridging the gap that separates the region from more developed countries regarding an optimal early childhood and maternal care. Extensive discussion was conducted to reach consensus recommendations on general strategies intended to reduce maternal and infant mortality associated with infections and immune-preventable diseases during the first 1,000 days of life in LAC.
RESUMEN
Resumen Introducción: Centroamérica experimenta una alta carga de la enfermedad por dengue aportando cerca de 8% de todos los casos del continente. Este trabajo reporta la epidemiología del dengue en la subregión en un período de 10 años. Objetivos: Documentar la epidemiología del dengue en Centro América y República Dominicana. Material y Métodos: Período de estudio: años 2005-2014. Se recopilaron y analizaron los datos de casos y muertes por dengue de los países de Centro América y República Dominicana, reportados por los Ministerios de Salud y se corroboró con los datos publicados en los boletines en línea y la base de datos interactiva de la Organización Panamericana de la Salud (OPS). Se obtuvieron estadísticas poblacionales de los Institutos Nacionales de Estadística y Censo de cada país. Resultados: Durante el período de estudio fueron notificados 1.118.464 casos de dengue. Reportados 32.431 casos graves, 888 personas fallecidas. La letalidad por caso de dengue fue en promedio 0,08%. Los cuatro serotipos de dengue circularon durante el decenio estudiado. Discusión: La información clínica y epidemiológica, indica tasas de incidencia alta, que han fluctuado en los últimos años, con co-circulación significativa de varios serotipos a la vez. Conclusiones: Se identificaron diferencias notorias en la recolección de datos de la vigilancia entre países. Se determinó un patrón epidemiológico heterogéneo.
Background: Central America experiences a high burden of dengue reporting about 8% of all cases in the continent. This work reports the epidemiology of dengue in the sub region in a 10 years period. Aim: To describe the epidemiology of dengue in Central America and the Dominican Republic. Methods: Study period from 2005 to 2014. The data on dengue cases and deaths of the countries of Central America and the Dominican Republic, reported by the Ministries of Health, were compiled and analyzed and corroborated with the data published in the online bulletins and the interactive database of the Pan American Health Organization (PAHO). Population statistics were obtained from the National Statistics and Census Institutes of each country. Results: During the study period, 1,118,464 cases of dengue were notified. There were 32,431 serious cases reported, 888 people died. The lethality per case of dengue was on average 0.08%. The four dengue serotypes circulated during the decade analyzed. Discussion: Clinical and epidemiological information indicates high incidence rates, which have fluctuated in recent years, with significant co-circulation of several serotypes at the same time. Conclusions: Notorious surveillance data collection differences were identified between countries, determining a heterologous epidemiological pattern.

Given that the last notified case of poliomyelitis due to wild poliovirus type 2 was in 1999, in 2012, the Strategic Advisory Group of Experts on Immunization (SAGE) of the World Health Organization (WHO) recommended the withdrawal of the type 2 component of oral polio vaccine (OPV) and the introduction of a bivalent OPV (bOPV) in all countries by 2016. WHO recommended also that the withdrawal should be preceded by the introduction of at least one dose of inactivated poliovirus vaccine (IPV) in routine immunization schedules. The introduction of IPV prior to the change of the bOPV in 2016 to trivalent OPV (tOPV) was based on the concept of ensuring that a substantial proportion of the population would be protected against type 2 polio after the removal of the type 2 OPV. However, the world's two producers of IPV (Bilthoven Biologicals and Sanofi) have faced problems in the production of this vaccine and therefore reported a reduction of the global supply of IPV. In response to the potential shortage of IPV, at a meeting held on March 10 2017, the SAGE and Technical Advisory Group (TAG) of the Pan American Health Organization (PAHO) urged the countries in the Latin American region to replace the routine administration of the full doses of inactivated polio vaccine (IPV-C) in the immunization schedule (administered by intramuscular route), administering a fraction of the full dose in two intradermal shots (IPV-f). The possibility of this strategy was analyzed by opinion leaders convened by the Paraguayan Society of Pediatrics with the support of the Latin American Society of Pediatric Infectious Diseases (SLIPE) and Latin American Association of Pediatrics (ALAPE). This document presents the results of the discussion.

Even though we have already covered 99% of the path to eradicate poliomyelitis from the world, this disease is still causing paralysis in children. Its eradication means not only the end of wild poliovirus circulation, but vaccine-derived poliovirus circulation as well. Taking into account different factors such as: current epidemiological data, adverse events of the attenuated oral poliomyelitis vaccine (OPV), the availability of an injectable inactivated vaccine (IPV) without the potential of causing the severe adverse events of the oral vaccine (OPV), the efficacy and effectiveness of the IPV in several countries of the world where it has been used for several years, the rationale of changing the vaccination schedule in different Latin American countries; the Latin American Society of Pediatric Infectious Diseases (SLIPE) announces its recommendation of switching to IPV in Latin America, by this Declaration, with an Action Plan for 2014-2015 period as regards vaccination against polio policies in Latin America. 1. The optimal proposed schedule consists of four IPV doses (three doses in the primary schedule plus a booster dose), whether IPV is combined or not with other indicated vaccines in the immunization program of the country. During the OPV to IPV transition phase, an alternative schedule is acceptable; 2. Countries should set optimal strategies in order to maintain and improve vaccination coverage, and implement a nominal immunization registry; 3. Improving the Epidemiological Surveillance of Acute Flaccid Paralysis (AFP) and setting up an environmental surveillance program; 4. Setting up strategies for introducing IPV in National Immunization Programs, such as communicating properly with the population, among others; 5. Bringing scientific societies closer to decision makers; 6. Ensuring optimal supply and prices for IPV introduction; 7. Training vaccination teams; 8. Enhancing the distribution and storing logistics of vaccines. In addition to the scientific evidence, the countries that have not yet decided to switch to IPV should consider the implications of equity and social justice.

Kawasaki disease is the leading cause of acquired cardiac disease in children. Although the epidemiology of the disease has been well described in Japan, other Asian countries, Europe, Australia and North America, the epidemiology and disease burden in Latin American children is unknown. For this reason, the idea of establishing a research network on Kawasaki disease in children from Latin America was born, becoming this the largest Kawasaki disease international multinational research network and in which 20 countries of the region will be integrated.

La enfermedad de Kawasaki representa la causa más común de cardiopatía adquirida en niños. Si bien es cierto que la epidemiología de la enfermedad ha sido muy bien descrita en Japón y otros países de Asia, Europa, Australia y Norte América, se desconoce la epidemiología y carga de enfermedad en niños de América Latina. Por esta razón nació la idea de establecer una red de investigación de enfermedad de Kawasaki en niños de América Latina, constituyéndose ésta en la red internacional multinacional más grande de investigación de la epidemiología de la enfermedad y donde se integran 20 países de la región.
