background emergence of a novel swine-origin influenza a (h1n1) pandemic since 2009 attracted the attention of scientists to characterize epidemiological features and clinical manifestations of this disease in comparison to seasonal flu in different parts of the world. objectives the goal of this investigation was to compare these features in confirmed cases of swine-origin influenza a (h1n1) a...

conclusions: prevalence rate of h1n1 infection in the study region was higher compared to other part of iran; but, close to the expected rate. the h1n1-associated mortality rate was lower than the reported rates in iran and other parts of the world. background: khuzestan and other parts of iran were involved with influenza a (h1n1) pandemic in 2009. objectives: the aim of this study was to desc...

In this report, we describe the occurrence of two novel swine influenza viruses (SIVs) in pigs in Argentina. These viruses are the result of two independent reassortment events between the H1N1 pandemic influenza virus (H1N1pdm) and human-like SIVs, showing the constant evolution of influenza viruses at the human-swine interface and the potential health risk of H1N1pdm as it appears to be maint...

The purpose of this study was to understand the geographic extent, risk factors, and attack rate of the 2009 pandemic influenza A (H1N1) virus [A(H1N1)pdm09] infection in Shandong Province, China and to identify the influencing factors. A randomized serological survey of A(H1N1)pdm09 infection was carried out in August and September 2010. A total of 4,549 participants involved in the survey ...

background: the preventive measures against h1n1 influenza are vitally important. the aim of the present study was to assess the knowledge, attitude and performance of academic hospital staff about h1n1 influenza. methods: this study was carried out on ali-ebne-abiltaleb hospital staff in rafsanjan, iran. the data gathering tool was a researcher made questionnaire comprised of 38 questions on d...

We report here the complete genome sequence of a triple-reassortant H1N1 swine influenza virus strain, A/swine/Guangxi/BB1/2013 (H1N1) (GXBB1), isolated from a swine in the Guangxi Province of southern China in 2013. We obtained the complete genome sequence of the GXBB1 virus. Sequence analysis demonstrated that this H1N1 virus was a triple-reassortant swine influenza virus (SIV) whose genes or...

Background: A new pandemic influenza A (H1N1) emerged in April 2009, causing considerable morbidity and mortality. Since mutations in the haemagglutinin (HA) may influence the antigenicity and pathogenicity of the virus, continued epidemiological and molecular characterization for the effective control of pandemic flu and developing of more appropriate vaccine is crucial. Objective: To monitor ...

background: influenza a (h1n1) pandemic is recently threatening the health of world's population. non-pharmaceutical measures are important to prevent the spread of influenza a (h1n1) and to prevent a pandemic. effective influenza pandemic management requires understanding of the factors influencing preventive behavioral changes. this study determined the status of preventive behaviors regardin...

background: primary health care workers (phcw) are the front-liners in any infectious disease outbreaks. the recent outbreak of h1n1 influenza demonstrated that uptake of h1n1 vaccination remained low amongst pchw despite its proven effectiveness. this trend is worrying as phcw are the first point of contact in any emerging outbreak of future influenza epidemic. purpose: to investigate factors ...
