Abstract:

Objective: 2009 H1N1 influenza was first detected in the Northern Hemisphere in April 2009. National data have suggested that the novel influenza virus disproportionately causes severe illness in children and young adults, a somewhat different presentation from traditional seasonal flu which normally strikes hardest in the very young and older adults. This may or may not be the case in Virginia, which, if it is different, may suggest a need to alter flu prevention messages and vaccine policy as the outbreak continues through the fall 2009-10 influenza season. This report examined the early pr

Abstract:

The swine-origin H1N1 influenza A pandemic virus (A(H1N1)pdm09) was detected in the human population in March 2009. Due to its antigenic novelty, the majority of individuals were susceptible to the virus and the pandemic quickly disseminated around the globe. Rapid characterization of the epidemic was required in order to help inform interventions and determine the risk posed to public health. Widespread sampling and sequencing of virus isolates enabled early characterization of the virus using phylogenetic analysis and continued surveillance over the subsequent three years of global circulati

Abstract:

Influenza is a highly contagious and acute respiratory infection caused by influenza virus in the mucosa of the respiratory tract. Both seasonal and pandemic influenza continue to cause substantial morbidity and mortality in humans. The 2009 pandemic H1N1 (pH1N1) influenza and the potential of a highly pathogenic avian H5N1 (aH5N1) pandemic highlighted the need for effective preventative strategies. Understanding the development of natural immunity following the pH1N1 pandemic may provide important information on host protective immunity in humans, which could inform future more effective vacc

Abstract:

Avian H5N1 viruses have perpetuated in poultry and caused sporadic human transmission since 1997. Vaccine candidates for the potential pandemic caused by H5N1 viruses have been continuously updated by World Health Organization. Multiple genetic lineages of H5N1 viruses which co-circulate and rapidly evolve in different regions, together with periodic population replacement of newly emerged genetic and antigenic variants in the field, pose great challenge for H5N1 vaccine candidate selection. The complexity of avian H5N1 viruses evolution raises an important issue for studying antigenic proper

Abstract:

Neuraminidase (NA) inhibitors are one of two classes of antiviral compounds available for the control of influenza infections. The H275Y NA mutation confers resistance to the NA inhibitor oseltamivir carboxylate among the N1 influenza subtype and has been identified from resistant variants with distinct epidemiological outcomes in human. Specifically, dominance of oseltamivir-resistant variant of the A/Brisbane/59/2007-like viruses was reported during the 2008 to 2009 influenza season, until it was replaced by the 2009 pandemic H1N1 virus [A(H1N1)pdm09].

The spread of pandemic influenza A (2009 H1N1 influenza) virus resulted in a global influenza pandemic in 2009. During the early stages of the pandemic, population surveillance was crucial. However, officials around the world realized that many of our surveillance and reporting systems were not prepared to respond in a coordinated, integrated way, which made informed public health decision-making very difficult.

Abstract:

The theme of my thesis is the issue of the new strain of influenza A (H1N1 Pandemic 2009) and the associated awareness of vaccination amongst the elderly. The work is divided into two parts, a theoretical and practical part. In the theoretical part, I tried to comprehensively process the available knowledge on the origins, epidemiology and prevention of influenza with particular emphasis on vaccination, oriented towards the elderly. The practical part is focused on mapping the awareness of the elderly of the issue of vaccination against influenza and analysis of results from a research explora

學校停課在世界各國的流感大流行應對方案中常被列為一項社區緩疫措施，而這項措施亦在2009年H1N1流感大流行中被廣泛地使用。然而，這項緩疫措施經常被質疑是否恰當，原因是因為停課會對教育構成重大的影響，而且過往的流行病學硏究亦表示這項緩疫措施不一定有效。本論文硏究學校停課對2009年H1N1流感大流行在香港首5個月疫情中降低大流行流感傳播的效能。<br>在香港，在該大流行流感病毒於2009年4月在美國被發現後，香港政府實施了控疫措施(containment phase measures)，並開始對該流感大流行進行監測。為了判定大流行是否已在香港內蔓延，衛生防護中心設定了一個報告準則來讓本地醫生報告疑似大流行流感感染個案，並為每個懷疑個案作確診測試及為每個確診個案追溯感染源頭。當大流行流感在6月開始在香港內蔓延時，香港政府實施了緩疫措施(mitigation phase measures)。在緩疫措施底下，帶有流感病症的病人求診於指定流感診所和公共醫院急症室會被測試是否感染大流行流感，而停課措施亦在此時開始實行去減低大流行流感的傳播。停課措施一直維持至7月直至暑假開始，並經修改後於9月開學時繼續實行。在9月，鑑於已不再需要對流感大流行進行監測，對懷疑感染個案進行確診測試的政策止於該月下旬。確診個案中記錄了的病人資料，與及由學校停課和暑假所引起的學期變化，為這課題提供了一個理想硏究的機會

HA is the major viral surface glycoprotein that binds to specific sialylated glycan receptors in the respiratory tract and allows the virus to enter the cell. It has been recognized as the key antigen in the host immune response to influenza virus in both natural infection and vaccination. We have shown that HA with a single N-linked N-acetylglucosamine (GlcNAc) at each glycosylation sites (monoglycosylated

In March and early April 2009, a novel influenza A virus H1N1 emerged in the United States and Mexico, which was named pandemic H1N1 2009 influenza A virus (2009 H1N1). Tracing its phylogeny, scientists found its genome was reassorted from human, avain and swine flu. The viral protein PB1-F2 is another translated product which ribosome possesses a leaky scanning when it is scanning on the open reading frame (ORF) of PB1. Its length is about 87~90 a.a. PB1-F2 had multiple functions w

Influenza viruses infect cells through the interaction between hemagglutinin (HA) and sialic acid on cell membrane. The antibody is useful in prophylaxis, therapy, vaccine design and diagnosis. In this study the trimeric HA protein from A/Texas/05/2009 expressed by a baculovirus-insect expression system was intraperitoneally inoculated into Balb/c mice to produce antibodies. The GCN4 peptide derived from yeast transcription factor in the recombinant HA protein is to form t

Abstract:

An influenza is an illness annually affecting 5-15 percent of the world population. During the influenza pandemy 40-50 percent of world population can be affected and millions of people can die.The measures resulting from the pandemic plans help to limit the influenza virus spreading, to reduce morbidity and mortality. In April 2009 the first cases of the flue pandemic caused by Pandemic A (H1N1) 2009 virus occurred on the American continent, in the Czech Republic there was the first case registered in May, in the Pilsen region in July. Based on these facts I decided to assess the pandemic pla

Because of the great change of antigenicity, the reassorted viruses have the potential to cause global pandemic such as 2009 pandemic H1N1. As the reports of the increase of human infection by the newly-reassorted swine influenza viruses subtype H3N2 carrying genes from 2009 pandemic H1N1 were observed, it is crucial to understand the antibody cross-reactivity between swin

Influenza virus belongs to the Orthomyxovirus family of viruses that causes respiratory infection in humans, leading to morbidity and mortality. The mature influenza A virion has an envelope that contains two major surface glycoproteins proteins – hemagglutinin (HA) and neuraminidase (NA). HA is a highly antigenic molecules and is responsible binding to host cell surface receptors (Sialic acid), and membrane fusion between the viral membrane and the host endosomal membrane. Most of the antibody response generated against influenza virus either by vaccination or by natural infection is directed
