BACKGROUND A global pandemic mortality study found prominent regional mortality variations in 2009 for Influenza A(H1N1)pdm09. Our study attempts to identify factors that explain why the pandemic mortality burden was high in some countries and low in others. METHODS As a starting point, we identified possible risk factors worth investigating for Influenza A(H1N1)pdm09 mortality through a targ...

PROBLEM Improving pandemic planning and preparedness is a challenge in Europe, a diverse region whose regional bodies (the Regional Office for Europe of the World Health Organization [WHO], the European Commission and the European Centre for Disease Prevention and Control) have overlapping roles and responsibilities. APPROACH European pandemic preparedness indicators were used to develop an a...

BACKGROUND A novel influenza virus has emerged to produce a global pandemic four times in the past one hundred years, resulting in millions of infections, hospitalizations and deaths. There is substantial uncertainty about when, where and how the next influenza pandemic will occur. METHODS We developed a novel mathematical model to chart the evolution of an influenza pandemic. We estimate the...

OBJECTIVES The pandemic of novel influenza A (H1N1) virus has required decision-makers to act in the face of the substantial uncertainties. In this study, we evaluated the potential impact of the pandemic response strategies in the Republic of Korea using a mathematical model. METHODS We developed a deterministic model of a pandemic (H1N1) 2009 in a structured population using the demographic...

BACKGROUND Massive growth in human mobility has dramatically increased the risk and rate of pandemic spread. Macro-level descriptors of the topology of the World Airline Network (WAN) explains middle and late stage dynamics of pandemic spread mediated by this network, but necessarily regard early stage variation as stochastic. We propose that much of this early stage variation can be explained ...

The 2009 influenza A/H1N1 pandemic caused an increase in complications in pregnant women. To be well prepared for a next pandemic, we investigated the obstetric and maternal complications of this pandemic. In our national cohort of 59 pregnant women who were admitted to the hospital, no major complications apart from preterm birth and admission to the neonatal intensive care unit were observed....

Title: The age distribution of mortality due to influenza: pandemic and peri-pandemic Author's response to reviews: see over

By examining the origins, pathways, demographic impact and consequences for the public, the medical profession and governments, of the so-called “Spanish” influenza pandemic of 1918-1919, this article establishes the main contours of the worst pandemic in modern history, which killed some 50 million people worldwide in eighteen months. In doing so, it also recognizes how closely this pandemic w...

Challenges facing seasonal and pandemic influenza vaccination include: increasing the immunogenicity of seasonal vaccines for the most vulnerable, increasing vaccination coverage against seasonal influenza, and developing vaccines against pandemic strains that are immunogenic with very low quantities of antigen to maximize the number of people who can be vaccinated with a finite production capa...

In pandemic situations, primary care providers may be involved in a variety of roles related to disease surveillance, diagnosis and treatment, prevention, and patient education. This commentary describes the contextual factors that may influence primary care providers' perspectives on their pandemic roles and responsibilities. These factors include the natural evolution of the pandemic situatio...
