Introduction: This study aimed to evaluate the clinical profile and outcomes of adult patients screened and diagnosed with H1N1 influenza infection at a tertiary care hospital in India. Materials and Methods: This retrospective study was conducted on all adult patients suspected of H1N1 influenza admitted at a teaching hospital during the epidemic period of January-March 2015. Patients were sc...
The pandemic H1N1 virus of 2009 (2009 H1N1) produced a spectrum of disease ranging from mild illness to severe illness and death. Respiratory symptoms were frequently associated with virus infection, with relatively high rate of gastrointestinal symptoms reported. To better understand 2009 H1N1 virus pathogenesis in humans, we studied virus and host responses following infection of two cell typ...
In 2015, a novel influenza A(H1N1) virus was isolated from a boy in China who had severe pneumonia. The virus was a genetic reassortant of Eurasian avian-like influenza A(H1N1) (EA-H1N1) virus. The hemagglutinin, neuraminidase, and matrix genes of the reassortant virus were highly similar to genes in EA-H1N1 swine influenza viruses, the polybasic 1 and 2, polymerase acidic, and nucleoprotein ge...
Among the influenza A viruses (IAVs) in wild aquatic birds, only H1, H2, and H3 subtypes have caused epidemics in humans. H1N1 viruses of avian origin have also caused 3 of 5 pandemics. To understand the reappearance of H1N1 in the context of pandemic emergence, we investigated whether avian H1N1 IAVs have contributed to the evolution of human, swine, and 2009 pandemic H1N1 IAVs. On the basis o...
چکیده زمینه و هدف: ظهور آنفولانزای a جدید h1n1 با منشأ حیوانی که توانایی انتقال از انسان به انسان را داشته باشد، یکی از عوامل ایجاد نگرانی در رابطه با همه گیری آن شده است. در حال حاضر، ویروس های آنفولانزایی که فصلی میان انسان ها منتشر می شوند ویروس آنفولانزای a و زیرمجموعه هایh1n1,h3n2 و نیز ویروس آنفولانزای b می باشند. هدف از این مطالعه شناسایی زیرمجموعه h3n2 و نوع جدید h1n1 (فصلی)از بیماران ...
Influenza A virus (H1N1) 2009, a new swine-origin influenza A virus, has been spread worldwidely and caused great public fear. High-throughput transcriptomics and proteomics methods are now being used to identify H1N1 and H1N1-host interaction. This article reviews recent transcriptomics and proteomics research in H1N1 diagnosis, treatment, and H1N1 virus-host interaction, to offer some help fo...
The pandemic influenza virus (2009 H1N1) was recently introduced into the human population. The hemagglutinin (HA) gene of 2009 H1N1 is derived from "classical swine H1N1" virus, which likely shares a common ancestor with the human H1N1 virus that caused the pandemic in 1918, whose descendant viruses are still circulating in the human population with highly altered antigenicity of HA. However, ...
Levels of preexisting antibodies to the hemagglutinin of pandemic influenza A(H1N1) 2009 (hereafter pandemic H1N1) virus positively correlate with age. The impact of contemporary seasonal influenza vaccines on establishing immunity to other pandemic H1N1 proteins is unknown. We measured serum antibodies to the neuraminidase (NA) of pandemic H1N1 in adults prior to and after vaccination with sea...
influenza h1n1 infection leading to cardiac tamponade in a previously healthy patient: a case report
conclusions this case highlights the potential severity of h1n1 infections and the utility of considering cardiac tamponade in patients presenting with influenza symptoms and circulatory collapse. case presentation we describe a case of a young female with no prior cardiovascular history who presents with a pericardial effusion and shock secondary to cardiac tamponade from pericarditis due to h...
Pandemic H1N1/2009 influenza virus, derived from a reassortment of avian, human, and swine influenza viruses, possesses a unique gene segment combination that had not been detected previously in animal and human populations. Whether such a gene combination could result in the pathogenicity and transmission as H1N1/2009 virus remains unclear. In the present study, we used reverse genetics to con...
