We would like to discuss the recent publication titled “Fulminant myocarditis associated with the H1N1 influenza virus: case report and literature review.”(1) In this report, Lobo et al. noted that “the H1N1 influenza virus should be considered an etiologic agent of myocarditis”(1) and concluded that “the use of extracorporeal membrane oxygenation therapy appears promising but has not yet been ...

Objectives: Influenza is one of the most important emerging and reemerging infectious diseases in the world. The aim of this study is molecular and phylogenetic analyses of the variations in circulating influenza A/H1N1 virus isolates during 2014-2015 in Iran and investigate on the drug resistance conditions in the related Iranian isolates. Material and Methods: Throat samples from Iranian pat...

Pre-existing immunity is an important factor countering the pandemic potential of an emerging influenza virus strain. Thus, studying of pre-existing immunity to the 2009 pandemic H1N1 virus (2009 H1N1) will advance our understanding of the pathogenesis and epidemiology of this emerging pathogen. In the present study, sera were collected from 486 individuals in a hospital in Shanghai, China, bef...

This work presents the results of studies on extract obtained from root Ferula kuhistanica Korov, in relation to 2 strains influenza virus: A/Vlad/2/09(H1N1) and A/Almaty/8/98(H3N2). It has been shown that F. Korov exhibits selective antiviral activity primarily acts virus strain A/Vlad/2/09(H1N1), not showing an inhibitory effect against another antigenic variant this – A/ Almaty/8/98(H3N2). T...

In March of 2009, a flu epidemic began in Mexico. Shortly thereafter, similar cases appeared in other countries, alerting authorities to the risk of a pandemic. This article details the principal signs and symptoms of infection with the swine-origin Influenza A (H1N1) virus. In addition, the measures to be taken in suspected or confirmed cases are addressed, as are the procedures to follow in r...

BACKGROUND Influenza pandemics are usually caused by the re-assortment of several influenza viruses, results in the emergence of new influenza virus strains that can infect the entire population. These pandemic strains, as well as seasonal influenza viruses, are subjected to extensive antigenic change that has, so far, prevented the generation of a universal vaccine. METHODS Samples of patien...

During an influenza pandemic, information about the industry and occupation (I&O) of persons likely to be infected with influenza virus is important to guide key policy decisions regarding vaccine prioritization and exposure-control measures. Health-care personnel (HCP) might have increased opportunity for exposure to influenza infection, and they have been prioritized for influenza vaccination...

Comparisons of the clinical characteristics of contemporaneous pandemic (H1N1) 2009 influenza A virus (A(H1N1)pdm09)- and seasonal influenza viruses-infected patients are important for both clinical management and epidemiological studies. A prospective multicenter observational study was conducted using a preestablished sentinel surveillance system in Guangzhou, China during 2009. In this s...

background and aims: each year, the influenza virus causes moderate to severe infections with a high prevalence throughout the world. accordingly, an influenza vaccine that ensures protection with only a single dose would be a much more cost effective approach to influenza prophylaxis. generation of influenza non-replicating virus-like particles (vlp) in baculoviral expression system is an attr...
