OBJECTIVE To evaluate ascertainment of the onset of community transmission of influenza A/H1N1 2009 (swine flu) in England during the earliest phase of the epidemic through comparing data from two surveillance systems. DESIGN Cross sectional opportunistic survey. STUDY SAMPLES Results from self samples by consenting patients who had called the NHS Direct telephone health line with cold or f...
BACKGROUND We set out to identify the level of previous exposure to influenza A (H1N1) in unvaccinated healthcare workers (HCWs) at the peak of the pandemic outbreak in the UK, with control samples collected prior to the outbreak. METHODS Cross-sectional study (seroprevalence assessed before and at pandemic peak, with questionnaire data collected at peak of outbreak) in HCWs in Scotland. RE...
Numerous resources relevant to the 2009 pandemic influenza are available on-line . A casual search in google using the phrase "swine flu resources" yields 9,180,000 items making a time-bound search less fruitful for an average health care professional. This review has summarized the contents useful to practicing clinician available in 12 websites which were selected based on their relevance to ...
Neighborhood determinants of 2009 pandemic A/H1N1 influenza vaccination in Montreal, Quebec, Canada.
Neighborhood-level analyses of influenza vaccination can identify the characteristics of vulnerable neighborhoods, which can inform public health strategy for future pandemics. In this study, the authors analyzed rates of 2009 pandemic A/H1N1 influenza vaccination in Montreal, Quebec, Canada, using individual-level vaccination records from a vaccination registry with census, survey, and adminis...
Predicting vaccination using numerical and affective risk perceptions: the case of A/H1N1 influenza.
During the 2009 A/H1N1 flu pandemic, German health authorities recommended vaccination; however, the efficacy of such programs largely depends on individuals' risk perception. Risk perceptions are commonly determined through numerical-cognitive estimates such as the perceived likelihood and severity of the hazard. Instead, we argue that risk perceptions, which include more affect-related aspect...
background: influenza viruses are a significant cause of morbidity and mortality. the influenza virus pandemics, 1918, 1977, and especially the most recent one, a/h1n1/2009, made evident the need for generating recombinant influenza h1n1 antigens which are essential to develop both basic and applied research programs. among influenza virus proteins, haemagglutinin (ha) is a major surface antige...
an outbreak of H1N1 influenza A virus infection was detected in Mexico, with subsequent cases observed in several other countries including the United States (1, 2). Though limited information was available on the early pre-pandemic situation in Mexico, subsequent cases in the U.S. and Canada had a common travel history of returning from Mexico, the epicenter of the current outbreak. After that...
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...
A remarkable feature of the 2009 pandemic H1N1 influenza virus is its efficient transmissibility in humans compared to that of precursor strains from the triple-reassortant swine influenza virus lineage, which cause only sporadic infections in humans. The viral components essential for this phenotype have not been fully elucidated. In this study, we aimed to determine the viral factors critical...
Here we present a review of the literature of influenza modeling studies, and discuss how these models can provide insights into the future of the currently circulating novel strain of influenza A (H1N1), formerly known as swine flu. We discuss how the feasibility of controlling an epidemic critically depends on the value of the Basic Reproduction Number (R0). The R0 for novel influenza A (H1N1...
