MicroRNAs have been implicated in the regulation of gene expression of various biological processes in a post-transcriptional manner under physiological and pathological conditions including host responses to viral infections. The 2009 pandemic H1N1 influenza virus is an emerging reassortant strain of swine, human and bird influenza virus that can cause mild to severe illness and even death. To...

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...

Purpose. To provide an overview of the 2009 H1N1 influenza pandemic and antiviral treatment options for influenza. Summary. Influenza infection causes significant morbidity and mortality every year. The high mutation rate and segmented nature of influenza virus genome gives rise to high genetic variability which enables the virus to escape antiviral and vaccine interventions. A novel H1N1 strai...

As one of the most effective drugs for influenza virus infection, clinical application of zanamivir is restricted with the emergence of resistant influenza virus. It is crucial to manufacture novel pharmaceuticals against influenza virus infection. In recent years silver nanoparticles (AgNPs) have attracted wide attention in the antiviral field. In this study, we demonstrated surface decoration...

A novel swine-origin H1N1 influenza A virus has been identified as the cause of the 2009 influenza pandemic in humans. Since then, infections with the pandemic (H1N1) 2009 influenza virus have been documented in a number of animal species. The first known cases of lethal respiratory disease associated with pandemic (H1N1) 2009 influenza virus infection in house pets occurred in domestic cats in...

To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004-2005 and 2009-2012, respectively. Genetic and epidemiologic analyses of human and swine influenza viruses indicated 2 events of A(H1N1)pdm09 virus spillover from humans to pigs.

BACKGROUND During the 2009 H1N1 immunization campaign, electronic and hybrid (comprising both electronic and paper components) systems were employed to collect client-level vaccination data in clinics across Canada. Because different systems were used across the country, the 2009 immunization campaign offered an opportunity to study the usability of the various data collection methods. METHOD...

BACKGROUND Shedding of the pandemic virus during an influenza pandemic is thought to persist longer than shedding of influenza viruses during annual influenza seasons, because people have much less immunity against a pandemic influenza. A correlation is thought to exist between the length of virus shedding and the clinical severity of influenza illness. METHODS We compared the virus isolation...

We describe the clinical characteristics and outcomes of adults hospitalized with pneumonia during the pandemic (H1N1) 2009 outbreak. Patients admitted to a general hospital in San Luis Potosí, Mexico, from April 10 through May 11, 2009, suspected to have influenza virus-associated pneumonia were evaluated. We identified 50 patients with suspected influenza pneumonia; the presence of influenza ...

The monthly mean percent positivites for B were 27%, 26%, 29%, and 49% for September, October, November, and December 2013, respectively. We observed 55% positivity for B in January 2014 and 58% for the first 2 weeks of February. Because these percentages were much greater than the national average of <4% [2], we compared the results obtained with the POCT to those obtained with the eSensor res...
