Mortality Burden Of The 2009 A/H1n1 Influenza Pandemic In France: Comparison To Seasonal Influenza And The A/H3n2 Pandemic, Magali Lematire, Fabrice Carrat, Gregoire Rey, Mark A. Miller, Lone Simonsen, Cecile Viboud

Global Health Faculty Publications

Background

The mortality burden of the 2009 A/H1N1 pandemic remains unclear in many countries due to delays in reporting of death statistics. We estimate the age- and cause-specific excess mortality impact of the pandemic in France, relative to that of other countries and past epidemic and pandemic seasons.

Methods

We applied Serfling and Poisson excess mortality approaches to model weekly age- and cause-specific mortality rates from June 1969 through May 2010 in France. Indicators of influenza activity, time trends, and seasonal terms were included in the models. We also reviewed the literature for country-specific estimates of 2009 pandemic excess mortality …

How To Minimize The Attack Rate During Multiple Influenza Outbreaks In A Heterogeneous Population, Isaac Chun-Hai Fung, Rustom Antia, Andreas Handel

Isaac Chun-Hai Fung

Background: If repeated interventions against multiple outbreaks are not feasible, there is an optimal level of control during the first outbreak. Any control measures above that optimal level will lead to an outcome that may be as sub-optimal as that achieved by an intervention that is too weak. We studied this scenario in more detail.
Method: An age-stratified ordinary-differential-equation model was constructed to study infectious disease outbreaks and control in a population made up of two groups, adults and children. The model was parameterized using influenza as an example. This model was used to simulate two consecutive outbreaks of the …

Influenza Immunization Status Among African Americans: Factors Influencing Vaccine Decisions, Chandra Russell Story

Doctoral Dissertations

A disproportionate number of African American adults are susceptible to influenza- related morbidity due to chronic health conditions. The purpose of this study was to examine factors influencing influenza vaccination decisions among African American adults ages 18 and older in Blount County, Tennessee. Factors included constructs of social influence, access, vaccine safety, doctor recommendations, and sources of knowledge regarding the flu vaccine. Research questions were formulated to specifically address factors influencing one’s decision to be immunized for influenza. The theory of planned behavior served as the framework for developing the study.

A survey based on national phone surveys was modified …

Variables Associated With Critical Illness Among Clark County Residence Hospitalized With H1n1 Influenza A Virus During The 2009 Influenza Season., Jonathan P. Hyatt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background:In 2009, a novel H1N1 Influenza A virus was detected in the population. Because it can potentially affect a different population than the influenza strains circulating for the past 35 years, it is critical for physicians, practitioners and public health organizations to understand who is susceptible to this disease, and which sub-populations are most likely to suffer critical illness. The objective of this study was to examine the factors unique to 2009 H1N1 infection, with the goal of finding the variables associated with ICU admission (Critical Illness) in the Clark County 2009 H1N1 patient.

Methods:Factors that were assessed in this …

Tetanus Toxoid, Reduced Diphtheria Toxoid And Acellular Pertussis Vaccination And Influenza Vaccination Of Pregnant And Postpartum Women, Colleen M. Mccormick

Master of Public Health Program Student Publications

Introduction: Infants ≤2 months are at greatest risk for morbidity/mortality from pertussis. Tdap vaccines given in late pregnancy or postpartum can protect infants from pertussis. Pregnancy increases risks for maternal and perinatal complications. Influenza vaccine (FLUV) given in pregnancy can protect women and newborns.

Objectives: To determine Tdap and FLUV rates in pregnant and postpartum patients and identify factors associated with vaccination.

Methods: Miami Valley Hospital delivery records from 01/2009-12/2011 were retrospectively reviewed. Data reviewed included age, insurance, race/ethnicity, and county of residence. Descriptive statistics analyzed prevalence of immunization, timing, and demographics. Chi-square and odds ratios detected differences between characteristics. …

Constrained Optimal Control For A Multi-Group Discrete Time Influenza Model, Paula Andrea Gonzalez Parra

Open Access Theses & Dissertations

During the last decades, mathematical epidemiological models have been used to understand the dynamics of infectious diseases and guide public health policy. In particular, several continuous models have been considered to study single in uenza outbreaks and the impact of dierent control policies. In this dissertation, a discrete time model is introduced in order to study optimal control strategies for in uenza transmission; since epidemiological data is collected on discrete units of time, a discrete formulation is more ecient. From a mathematical point of view, continuous time model are easier to analyze, however, the numerical solution of discrete-time models is …

Patent Landscape Of Influenza A Virus Prophylactic Vaccines And Related Technologies, Jon R. Cavicchi, Stanley P. Kowalski, David L. Pflugh, Jeremy Barton, Jeffrey Janovetz, John Schroeder

Law Faculty Scholarship

Executive Summary: This report focuses on patent landscape analysis of technologies related to prophylactic vaccines targeting pandemic strains of influenza. These technologies include methods of formulating vaccine, methods of producing of viruses or viral subunits, the composition of complete vaccines, and other technologies that have the potential to aid in a global response to this pathogen. The purpose of this patent landscape study was to search, identify, and categorize patent documents that are relevant to the development of vaccines that can efficiently promote the development of protective immunity against pandemic influenza virus strains.

The search strategy used keywords which the …

Influenza In The 21st Century : Assessment Of The 2009 H1n1 Pandemic Severity, Enhanced Surveillance Methods, And Pediatric Influenza-Associated Deaths, Dina M. Hoefer

Legacy Theses & Dissertations (2009 - 2024)

Influenza is among the most important of the endemic, epidemic, and pandemic diseases infecting humans. In June 2009, the World Health Organization raised the worldwide pandemic alert level to Phase 6 in response to the ongoing global spread of 2009 pandemic influenza A (H1N1) virus (pH1N1).1 The 2009 H1N1 influenza pandemic presented a unique opportunity and provided resources to monitor and study influenza in a way that would and could not be supported during a `typical' influenza season. Research objectives included: 1) characterizing the severity of illness among hospitalized patients infected with pH1N1; 2) assessing the utility of hospital discharge …
