Feasibility study for the use of self-collected nasal swabs to identify pathogens among participants of a population-based surveillance system for acute respiratory infections (GrippeWeb-Plus)-Germany, 2016.

Influenza Other Respir Viruses 2019 Mar 29. Epub 2019 Mar 29.

Department of Infectious Disease Epidemiology, Robert Koch Institute, Berlin, Germany.

Background: Internet-based participatory surveillance systems, such as the German GrippeWeb, monitor the frequency of acute respiratory illnesses on population level. In order to interpret syndromic information better, we devised a microbiological feasibility study (GrippeWeb-Plus) to test whether self-collection of anterior nasal swabs is operationally possible, acceptable for participants and can yield valid data.

Methods: We recruited 103 GrippeWeb participants (73 adults and 30 children) and provided them with a kit, instructions and a questionnaire for each sample. Read More

Influenza A virus shedding reduction observed at 12 weeks post-vaccination when newborn pigs are administered live-attenuated influenza virus vaccine.

Influenza Other Respir Viruses 2019 May 6;13(3):274-278. Epub 2019 Mar 6.

Boehringer Ingelheim Vetmedica GmbH, Ingelheim, Germany.

Background: Influenza A virus in swine (IAV-S) causes an acute respiratory disease of swine which results in great economic losses. A bivalent H1N1 and H3N2, NS1-truncated live-attenuated IAV-S vaccine (LAIV, Ingelvac Provenza ) has recently become available.

Objective: Reduction of shedding during an outbreak in the nursery or finisher is an important parameter from an epidemiological control strategy; therefore, a laboratory efficacy study was conducted to evaluate nasal virus shedding when vaccinated pigs were challenged with either heterologous H1N2 or H3N2 strains 12 weeks post-vaccination.

Authors:
E Thomas Ewing

Influenza Other Respir Viruses 2019 May 12;13(3):279-287. Epub 2019 Feb 12.

Department of History, Virginia Tech, Blacksburg, Virginia.

Background: The Russian influenza, which began in late 1889, has long been recognized as a major global epidemic yet available statistical evidence for morbidity and mortality has not been fully examined using historical and epidemiological tools. This study of cases and deaths in Indiana during the extended time period associated with the Russian influenza is the first scholarly effort to determine the number of victims from this influenza outbreak across a broad regional case study in the US.

Influenza Other Respir Viruses 2019 Mar 9;13(2):115-122. Epub 2019 Jan 9.

Japan Physicians Association, Influenza Study Group, Tokyo, Japan.

Background: The large consumption of neuraminidase inhibitors (NAIs) for the treatment of influenza virus infections places Japan at risk of becoming the epicenter of the global spread of NAI-resistant viruses.

Objective: To clarify NA amino acid mutations of epidemic influenza viruses in Japan and their related NAI resistance.

Antigenic evolution of H3N2 influenza A viruses in swine in the United States from 2012 to 2016.

Influenza Other Respir Viruses 2019 Jan 7;13(1):83-90. Epub 2018 Oct 7.

Virus and Prion Research Unit, National Animal Disease Center, USDA-ARS, Ames, Iowa.

Background: Six amino acid positions (145, 155, 156, 158, 159, and 189, referred to as the antigenic motif; H3 numbering) in the globular head region of hemagglutinin (HA1 domain) play an important role in defining the antigenic phenotype of swine Clade IV (C-IV) H3N2 IAV, containing an H3 from a late 1990s human-to-swine introduction. We hypothesized that antigenicity of a swine C-IV H3 virus could be inferred based upon the antigenic motif if it matched a previously characterized antigen with the same motif. An increasing number of C-IV H3 genes encoding antigenic motifs that had not been previously characterized were observed in the U. Read More

Coenzyme Q10 in acute influenza.

Influenza Other Respir Viruses 2019 Jan 30;13(1):64-70. Epub 2018 Sep 30.

Department of Emergency Medicine, Beth Israel Deaconess Medical Center, Boston, Massachusetts.

Objectives: The goal of this investigation was to determine if acute influenza infection is associated with depletion of CoQ10 compared to healthy controls and to determine any associations between CoQ10 levels and illness severity and inflammatory biomarkers.

Patients And Methods: We analyzed serum CoQ10 concentrations of patients with acute influenza enrolled in a randomized clinical trial prior to study drug administration. Patients were enrolled at a single urban tertiary care center over 3 influenza seasons (December 27, 2013 to March 31, 2016). Read More

Mapping influenza activity in emergency departments in France using Bayesian model-based geostatistics.

Influenza Other Respir Viruses 2018 11 21;12(6):772-779. Epub 2018 Aug 21.

Mathematical Modelling of Infectious Diseases Unit, Institut Pasteur, Paris, France.

Background: Maps of influenza activity are important tools to monitor influenza epidemics and inform policymakers. In France, the availability of a high-quality data set from the Oscour surveillance network, covering 92% of hospital emergency department (ED) visits, offers new opportunities for disease mapping. Traditional geostatistical mapping methods such as Kriging ignore underlying population sizes, are not suited to non-Gaussian data and do not account for uncertainty in parameter estimates.

Department of Population Medicine, Harvard Pilgrim Health Care Institute, Boston, Massachusetts.

Electronic data collected from routine health care can be used for public health surveillance. To examine the Sentinel System, a distributed data network of health plans, as a source for influenza surveillance, we compared trends in outpatient prescription dispensings of influenza antivirals in Sentinel to trends in CDC's ILINet and NREVSS systems over five seasons. There were 2 102 885 dispensed prescriptions of oseltamivir capsules, 494 188 of oseltamivir powder, and 7955 of zanamivir. Read More

Influenza Other Respir Viruses 2019 Jan 20;13(1):10-17. Epub 2018 Nov 20.

Influenza Division, National Center for Immunization and Respiratory Diseases, U.S. Centers for Disease Control and Prevention, Atlanta, Georgia.

Background: Within-country differences in the timing of RSV and influenza epidemics have not been assessed in Argentina, the eighth largest country in the world by area.

Objective: We aimed to compare seasonality for RSV and influenza both nationally and in each of the five regions to inform Argentina's prevention and treatment guidelines.

Influenza forecast optimization when using different surveillance data types and geographic scale.

Influenza Other Respir Viruses 2018 11 21;12(6):755-764. Epub 2018 Aug 21.

Department of Environmental Health Sciences, Mailman School of Public Health, Columbia University, New York City, New York.

Background: Advance warning of influenza incidence levels from skillful forecasts could help public health officials and healthcare providers implement more timely preparedness and intervention measures to combat outbreaks. Compared to influenza predictions generated at regional and national levels, those generated at finer scales could offer greater value in determining locally appropriate measures; however, to date, the various influenza surveillance data that are collected by state and county departments of health have not been well utilized in influenza prediction.

Objectives: To assess whether an influenza forecast model system can be optimized to generate accurate forecasts using novel surveillance data streams. Read More
