Although several studies have reported attenuated influenza illness following vaccination, results been inconsistent and focused predominantly on adults in the USA. This study aimed to evaluate severity of by vaccination status a broad range vaccine target groups across multiple South American countries.We analysed data from four countries (Argentina, Brazil, Chile, Paraguay) participating REVELAC-i, multicentre, test-negative design, effectiveness network including 41 sentinel hospitals....
Abstract Background To better establish the value of vaccination against influenza viruses, we estimated vaccine-averted illnesses among young children and older adults in Chile, Guyana, Paraguay. Methods We gathered country- target population-specific data on monthly hospitalizations, vaccine coverage, effectiveness from surveillance records immunization registries during 2013-2018. applied a static compartmental model to estimate differences number influenza-associated respiratory disease...
We estimate annual viral influenza-associated mild-to-moderate illness, hospitalizations, and deaths in six South American countries (Argentina, Brazil, Chile, Ecuador, Paraguay, Uruguay) during the 2015-2019 influenza seasons as a first step evaluating full value of vaccination subregion. applied multiplier methodology using monthly hospital discharge vital statistics death records, surveillance data, population projections to deaths. estimated uncertainty bounds based on 2.5th 97.5th Monte...
Despite having influenza vaccination policies and programs, countries in the Americas underutilize seasonal vaccine, part because of insufficient evidence about severe burden. We aimed to estimate annual burden influenza-associated respiratory hospitalizations Americas.Thirty-five with national surveillance were invited provide monthly laboratory data hospital discharges for illness (International Classification Diseases 10th edition J codes 0-99) during 2010-2015. In three age-strata (<5,...
based on data up to 23 July 2023 In this update, in addition the influenza surveillance information, that of SARS-CoV-2 by Global Influenza Surveillance and Response System (GISRS) through its associated sentinel non-sentinel systems reported platform FluNet hosted RespiMART is included.Information respiratory syncytial virus (RSV) included where available. Summary▪ Countries are recommended monitor relative co-circulation viruses integrated report (FluNet FluID) directly or via regional...
To reduce influenza-associated morbidity and mortality, countries in South America recommend annual influenza vaccination for persons at high risk severe illness, including young children, with preexisting health conditions, older adults. Interim estimates of vaccine effectiveness (VE) from Southern Hemisphere can provide early information about the protective effects help guide Northern advance their season. Using data a multicountry network, investigators estimated interim VE against acute...
In 2013, the Pan American Health Organization established a multi-site, multi-country network to evaluate influenza vaccine effectiveness (VE). We pooled data from five consecutive seasons in countries conduct an analysis of southern hemisphere VE against laboratory-confirmed hospitalizations young children and older adults.We used test-negative design estimate hospitalized (aged 6─24 months) adults ≥60 years) Argentina, Brazil, Chile, Colombia, Paraguay. Following country-specific...
Vaccine effectiveness (VE) is essential to monitor the performance of vaccines and generate strategic information guide decision making. We pooled data from six Latin American countries estimate COVID-19 in preventing laboratory-confirmed SARS-CoV-2 hospitalisation during three different pandemic waves February 2021 September 2022.We used a test-negative case-control design hospitalised adults Chile, Costa Rica, Ecuador, Guatemala, Paraguay, Uruguay. estimated adjusted VE by age group (18-64...
Objective There are limited published data about the circulation of influenza B/Victoria and B/Yamagata in Latin America Caribbean (LAC) most countries have a vaccine policy that includes use trivalent vaccine. We analyzed surveillance to inform decision-making LAC prevention strategies, such as quadrivalent Methods total 28 reference laboratories National Influenza Centers conduct virologic according global standards, on weekly basis upload their open-access World Health Organization (WHO)...
Cervical cancer is a global health concern and ranks fourth among the most prevalent cancers in women worldwide. Human papillomavirus (HPV) infection known precursor of cervical preventive measures include prophylactic vaccines. This study focused on sexually active Paraguayan aged 18–25 years, exploring intersection HPV vaccination sexual behavior. Among 254 participants, 40.9% received Gardasil-4 vaccine, with no significant differences behavior between vaccinated unvaccinated groups....
Introducción: A nivel mundial, el cáncer de cuello uterino es cuarto más frecuente en la mujer. Objetivo: Describir las coberturas anuales vacunación contra VPH y ESAVI. Material Métodos: Estudio observacional descriptivo transversal, realizado Paraguay, periodo 2013-2023, variables analizadas: niñas 10 años, según esquema: 3 dosis (2013-2016), 2 (2017-2023), seguimiento a los 15 años (1ª Dosis Final), ESAVI grave no grave. Resultados: Los intervalos 1ª dosis: 55-73% (periodo pandémico),...
Una cepa triple reasortante del virus Influenza A emergió en al año 2009 dando origen a una pandemia que alcanzó Paraguay junio mismo año. Con el fin de investigar la evolución genética influenza (H1N1) pdm09 fueron analizadas las secuencias nucleotÃdicas Gen Hemaglutinina 20 cepas A(H1N1)pdm09, aisladas Centro Nacional entre los años y 2016, secuenciadas Colaborador OPS/OMS Atlanta USA. El análisis filogenético muestra circulación menos 5 grupos genéticos bien diferenciados...
Introducción: La pandemia de COVID-19 produjo una crisis sanitaria afectando las coberturas vacunación los países. Objetivo: Describir la cobertura biológicos trazadores durante el periodo prepandémico (2015- 2019) y pandémico (2020-2021) en Paraguay. Materiales Métodos: Estudio descriptivo observacional corte transverso, que comprendió a niños 0 5 años edad, 18 Regiones Sanitarias del País. Se analizaron Programa Ampliado Inmunización, (2015-2019) (2020-201). incluyeron trazadores: BCG,...
INTRODUCTION:The influenza surveillance system in Paraguay has shown a similar profile the viral etiology last years, until on September 26 th , 2013 when there was an alert due to suspected drug intoxications by antitussive syrups.Suspected patients were experiencing influenza-like Illnesses.Due high auto-medication rate among cases, Ministry of Public Health began massive communication campaign against and stimulated medical consultation.The objective this report is give interpretation ILI...
