BACKGROUND With the release of the H1N1 vaccine, there was much controversy surrounding its use despite strong encouragements to be vaccinated in the media. Though studies have examined factors influencing people's decision to be vaccinated, few have focused on how general beliefs about the world or where an individual gathers information might influence that decision. METHODOLOGY/PRINCIPAL F...
Pandemic influenza A (H1N1) 2009 virus spread rapidly around the world in 2009. We used multiple data sources from surveillance systems and specific investigations to characterize the transmission patterns of this virus in China during May-November 2009 and analyze the effectiveness of border entry screening and holiday-related school closures on transmission. In China, age distribution and tra...
background in 2009, a pandemic associated with a new type of influenza a virus (h1n1) affected many countries worldwide. after five years of silence, in 2015 we encountered another outbreak of h1n1 influenza a. objectives the present study aimed to study the epidemiological and clinical features of this disease in the cold and dry climate of qazvin province, iran in the last epidemic, during 20...
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...
Asia is considered an important source of influenza A virus (IAV) pandemics, owing to large, diverse viral reservoirs in poultry and swine. However, the zoonotic origins of the 2009 A/H1N1 influenza pandemic virus (pdmH1N1) remain unclear, due to conflicting evidence from swine and humans. There is strong evidence that the first human outbreak of pdmH1N1 occurred in Mexico in early 2009. Howeve...
ویروس آنفلوآنزا یکی از مهمترین عوامل عفونی ایجاد کننده مرگ ومیر در سراسر جهان است. واکسن تجاری آنفلوانزا که به طور سالیانه بر اساس ویروس غالب در گردش طراحی می شود تنها قادر به ایجاد حفاظت نسبی در بالغین سالم است. از این رو، ما به واکسن کارامدتری نیاز داریم که به تغییر هر ساله نیاز نداشته باشد. ژن نوکلئو پروتئین (np) ویروس آنفلوآنزا به دلیل جهش پایین در بین اعضای یک نوع از ویروس های آنفلوانزا مش...
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 and purpose: Influenza is a respiratory infection that annually affects 5-15% of the global population. Influenza A/H1N1 is the most virulent human pathogens that results in a more severe disease and was first reported in 2009. The aim of this study was to investigate the epidemiology of influenza A/H1N1 in patients referring to several hospitals in North of Iran during 2009-2011. ...
Background and purpose: Influenza viruses annually spread around the world in seasonal epidemics. The A/H1N1 virus causes more severe conditions compared to other types of Influenza A. This study is an epidemiological survey of influenza A/H1N1 virus in patients attending health care centers in north of Iran during 2013-2017. Materials and methods: Sampling was done in 3037 patients. Influenza...
