Resumo: Real-world estimates of seasonal influenza vaccine effectiveness (VE) are important for early detection of vaccine failure. We developed a method for evaluating real-time in-season vaccine effectiveness (IVE) and overall seasonal VE. In a retrospective, register-based, cohort study including all two million individuals in Stockholm County, Sweden, during the influenza seasons from 2011/12 to 2014/15, vaccination status was obtained from Stockholm's vaccine register. Main outcomes were hospi (mais)

Influenza und ambulant erworbene Pneumonie in hausärztlich tätigen Arztpraxen in Deutschland./ [Influenza and community acquired pneumonia in German primary care].

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27695937
Resumo: Influenza and community-acquired pneumonia (CAP) impose a considerable annual burden on the German primary care system. Yet there is a lack of epidemiological data from the country's outpatient sector on groups at risk as well as on the complications of these diseases.The Robert Koch Institute (RKI) initiated the study to identify population groups at increased risk for influenza or CAP as well as related comorbidities and sequelae. We present the methodology of the study and the descript (mais)

Autor(es): Salzberger, Bernd; Schmidt, Barbara

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27701689
Resumo: The burden of disease of influenza in Germany has been dominated by high rates of complications in elderly patients in years with high circulation of H3N2 viruses after the introduction of the new H1N1 strain in 2009. Human infections with avian influenza viruses occur mostly in China. Due to the potential of reassortment with human strains these cases are monitored closely. The efficacy of neuraminidase inhibitors (NI) has been newly rated. In randomized studies effects on reduction of com (mais)

Resumo: The 2014/15 influenza season in Japan was characterised by predominant influenza A(H3N2) activity; 99% of influenza A viruses detected were A(H3N2). Subclade 3C.2a viruses were the major epidemic A(H3N2) viruses, and were genetically distinct from A/New York/39/2012(H3N2) of 2014/15 vaccine strain in Japan, which was classified as clade 3C.1. We assessed vaccine effectiveness (VE) of inactivated influenza vaccine (IIV) in children aged 6 months to 15 years by test-negative case-control desi (mais)

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27277013
Resumo: We estimated whether previous episodes of influenza and trivalent influenza vaccination prevented laboratory-confirmed influenza in Navarre, Spain, in season 2013/14. Patients with medically-attended influenza-like illness (MA-ILI) in hospitals (n = 645) and primary healthcare (n = 525) were included. We compared 589 influenza cases and 581 negative controls. MA-ILI related to a specific virus subtype in the previous five seasons was defined as a laboratory-confirmed influenza infection wit (mais)

Resumo: During the 2015-16 influenza season (October 4, 2015-May 21, 2016) in the United States, influenza activity* was lower and peaked later compared with the previous three seasons (2012-13, 2013-14, and 2014-15). Activity remained low from October 2015 until late December 2015 and peaked in mid-March 2016. During the most recent 18 influenza seasons (including this season), only two other seasons have peaked in March (2011-12 and 2005-06). Overall influenza activity was moderate this season, w (mais)

Resumo: INTRODUCTION: Pregnancy is a risk factor for severe influenza. However, data on influenza incidence during pregnancy are scarce. Likewise, no data are available on influenza vaccine coverage in France since national recommendation in 2012. We aimed to assess these points using a novel nationwide web-based surveillance system, G-GrippeNet. METHODS: During the 2014/2015 influenza season, pregnant women living in metropolitan France were enrolled through a web platform (https://www.grippenet.f (mais)

Fonte: Mil Med;181(4): 364-8, 2016 Apr.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27046183
Resumo: In this report, we describe and analyze a periodic pattern in influenza-like illness within active military populations, derived from the Defense Medical Surveillance System data set. We find that there is a well-defined pattern with peak incidence on Monday, decaying to Friday, and remaining roughly constant over the weekend. Moreover, we find that the pattern systematically changes in response to public holidays. We quantitatively describe the effect of this modulation, and show how these (mais)

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27108224
Resumo: BACKGROUND: Early detection of emergent influenza strains is a global health priority. However, maintaining active surveillance is economically and logistically challenging. While community-based surveillance is an attractive alternative, design and operation of an effective epidemiological surveillance program requires community engagement that can be linked to public health reporting and response. We report the results of a study in rural Guatemalan communities aimed at identifying opport (mais)
