BACKGROUND The US Army Medical Research Unit-Kenya (USAMRU-K) conducts surveillance for influenza-like illness (ILI) in Kenya. We describe the temporal and geographic progression of A(H1N1)pdm09 as it emerged in Kenya and characterize the outpatient population with A(H1N1)pdm09 infection. METHODS We included patients with ILI aged 2 months to 18 years enrolled during June 2009-August 2010. Re...
Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. Objective: In this study we aim to measure,...
Cell-mediated immunity to influenza A/USSR (H1N1) virus was assessed by measuring transformation response and interferon production by Ficoll-Hypaque-purified peripheral blood lymphocytes from children and adults. Lymphocyte transformation was found to be related to the individual's previous experience with H1N1 influenza virus. Lymphocyte cultures, obtained from adults who had their last conta...
The neuraminidase (NA) of influenza virus is the target of anti-flu drugs oseltamivir and zanamivir. Clinical practices showed that oseltamivir was effective to treat the 2009-H1N1 influenza but failed to the 2006-H5N1 avian influenza. To perform an in-depth analysis on such a drug-resistance problem, the 2009-H1N1-NA structure was developed. To compare it with the crystal 2006-H5N1-NA structur...
Introduction: According to marked advances in bioinformatics studies, development of influenza vaccines has been greatly modified in many studies. In this study, we have designed a multi-epitope recombinant protein, consisting of several conserved epitopes from Hemagglutinin protein of the H1N1 and H5N1 strains of Influenza virus by immunoinformatics approaches. Materials and Methods: The regis...
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...
