Introduction Literature on influenza focuses A, despite B having a large public health impact. The Global Influenza Study aims to collect information global epidemiology and burden of disease since 2000. Methods Twenty‐six countries in the Southern ( n = 5) Northern 7) hemispheres intertropical belt 14) provided virological epidemiological data. We calculated proportion cases due type Victoria Yamagata lineages each country season; tested correlation between maximum weekly influenza‐like...
We describe the epidemiological characteristics, pattern of circulation, and geographical distribution influenza B viruses its lineages using data from Global Influenza Study. included over 1.8 million cases occurred in thirty-one countries during 2000–2018. calculated proportion caused by lineages; determined timing A epidemics; compared age B/Victoria B/Yamagata cases; evaluated frequency lineage-level mismatch for trivalent vaccine. The median virus was 23.4%, with a tendency (borderline...
Influenza disease burden varies by age and this has important public health implications. We compared the proportional distribution of different influenza virus types within strata using surveillance data from twenty-nine countries during 1999-2014 (N=358,796 cases). For each virus, we calculated a Relative Illness Ratio (defined as ratio percentage cases in an group to country population same group) for young children (0-4 years), older (5-17 adults (18-39 (40-64 elderly (65+ years). used...
Introduction Determining the optimal time to vaccinate is important for influenza vaccination programmes. Here, we assessed temporal characteristics of epidemics in Northern and Southern hemispheres tropics, discuss their implications Methods This was a retrospective analysis surveillance data between 2000 2014 from Global Influenza B Study database. The seasonal peak defined as week with most reported cases (overall, A, B) season. duration activity using maximum proportion during three...
Introduction The increased availability of influenza surveillance data in recent years justifies an actual and more complete overview epidemiology Latin America. We compared the systems assessed A B, including spatio-temporal patterns epidemics, ten countries sub-national regions Methods aggregated by year country characteristics eighty-two were analysed. calculated median proportion laboratory-confirmed cases caused each virus strain, timing amplitude primary secondary peaks between...
During 2009 occurred the emergence and global spread of a novel influenza A (H1N1) virus. We describe clinical epidemiologic features hospitalized patients who survived died because pandemic infection reported in Santa Fe, Argentina, from May to July 2009.Using medical charts, we collected data on 242 were with confirmed laboratory results (defined as positive by specific PCR for H1N1).During study period, there cases hospitalization or death. Of 242, 46% admitted an intensive care unit...

Influenza Other Respiratory Viruses DOI: 10.1111/irv.12022. Background We estimated rates deaths Argentina, a country that recommends annual influenza vaccination for persons at high risk complications from illness. Methods identified hospitalized diagnosed with pneumonia (P&I, ICD‐10 codes J10‐J18) respiratory circulatory illness...
Introduction While there is much information about the burden of influenza A(H1N1)pdm09 in North America, little data exist on its South America. Methods During April to December 2009, we actively searched for persons with severe acute respiratory infection and influenza-like illness (ILI) three sentinel cities. A proportion case-patients provided swabs testing. We estimated number that would have tested positive by multiplying untested who positive. rates dividing census population after...
It is important to characterize the clinical and epidemiological pattern of influenza A (H1N1) pdm09 virus compare it with (H3N2) virus, as surveyed in just a few studies, order contribute implementation strengthening control prevention strategies. The aims this study were describe characteristics hospitalized patients, caused by (H1N1)pdm09 viruses during 2013, Santa Fe, Argentina. retrospective was conducted over 2013 among patients laboratory‐confirmed diagnosis. In contrast (20.5%),...
Epidemiologic and clinical characteristics of children with disease due toBordetella pertussis in Santa Fe, ArgentinaIntroduction: Pertussis, a vaccine-preventable respiratory disease, remains public health problem.Objective: The goal this study is to describe epidemiological patterns B. pertussis-caused infection over the period 2006-2010 Argentina.Methods: Inpatients outpatients < 14 years age, meeting case definition criteria were included.Household family contacts confirmed cases...
Objetivos. Descubrir el efecto de las epidemias influenza sobre la mortalidad y determinar criterio más apropiado para predecir magnitud ésta, a fin brindar un método que alerte precozmente gravedad una epidemia influenza. Métodos. El estudio se realizó en La Capital, departamento provincia Santa Fe, Argentina, durante período 1992-1999. Para lograr primer objetivo llevó cabo análisis retrospectivo los datos por neumonía e personas mayores 65 años, utilizando autorregresivo integrado...
Human rhinoviruses (HRVs) were historically considered upper airway pathogens. However, they have recently been proven to cause infections in the lower respiratory tract, resulting hospitalization of children with pneumonia, bronchiolitis, and chronic pulmonary obstruction. In this report, HRV frequency seasonality are described together patient clinical-epidemiological aspects. From a total 452 surveyed samples, nucleic acids was detected 172 (38.1%) found every month study year. 60%...
Influenza viruses have a relevant public health impact.To describe the activity of influenza and assess morbidity mortality impact during 2005 to 2010 in Santa Fe, Argentina.Epidemiological virological indicators were calculated based on sentinel surveillance. Mortality data from patients over under age 65 analyzed using integrated autoregressive moving average model an excess attributable was determined.The viral circulation effect measured through evolution proportion influenza-like...
A large proportion of acute respiratory tract infections (ARTI) remain without etiologic diagnosis, reason why new pathogens are investigated continuously. Human bocavirus (HBoV) was discovered in 2005, as a member Parvoviridae family and proposed to cause ARTI.To know the prevalence HBoV among pediatric populations hospitalized for ARTI two provinces Argentina: Santa Fe Tucuman; describe epidemiological clinical aspects associated its detection.We studied nasopharyn-geal aspirates patients...
En el contexto de la pandemia COVID-19, a partir 2020, Unidad Centinela Enfermedades Tipo Influenza (UC- ETI) (Santa Fe, Argentina) integró vigilancia clínica y por laboratorio SARS-CoV-2 rinovirus (HRV) habitual influenza otros virus respiratorios (OVR). El objetivo este estudio transversal retrospectivo fue describir las características clínico-epidemiológicas casos ETI ciudad Santa con diagnóstico HRV confirmado durante 2020-2021, en marco UC-ETI. Del total 600 cuyas muestras fueron...
