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 …
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 …

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 …
