BACKGROUND The 2009 H1N1 influenza pandemic caused offseason peaks in temperate regions but coincided with the summer epidemic of seasonal influenza and other common respiratory viruses in subtropical Hong Kong. This study was aimed to investigate the impact of the pandemic on age-specific epidemic curves of other respiratory viruses. METHODS Weekly laboratory-confirmed cases of influenza A (...
BACKGROUND The 2009 pandemic H1N1 influenza virus emerged in March 2009 and spread rapidly, causing many thousands of deaths worldwide. A case-control study of 60 Mexican adults with H1N1 suggested that the seasonal influenza vaccine protected against H1N1 infection (odds ratio [OR], 0.27; 95% confidence interval [CI], 0.11-0.66), but subsequent studies have had varied results and few have addr...
Abstract Background and Objective: The emergence of a novel H1N1influenza A virus of animal origin with transmissibility from human to human poses pandemic concern. Current subtypes of Seasonal influenza A viruses spread in human are influenza A H1N1 influenza A H3N2 and influenza type B viruses. The aim of this study was to determine current strains of the H3N2 and new H1N1 subtypes of influe...
There is uncertainty whether the 2009 seasonal influenza vaccination influences the risk of infection with the 2009 pandemic influenza A(H1N1) virus. This issue was investigated in 548 healthcare workers from Capital and Coast District Health Board, Wellington, New Zealand, presenting with influenza-like illness during the influenza pandemic between June and August 2009. All workers completed a...
OBJECTIVE To compare the patient characteristics, clinical features and outcomes of adult patients hospitalised with pandemic (H1N1) 2009 influenza and seasonal influenza. DESIGN AND SETTING Retrospective medical record review of all patients admitted to Liverpool Hospital, Sydney, with laboratory-confirmed influenza from the initiation of the "PROTECT" phase of the pandemic response on 17 Ju...
background and aims: influenza a viruses are important pathogens for humans especially in pandemic episodes. two adamantane derivates, amantadine and rimantadine, are used for prophylaxis and treatment of influenza a virus infections. however, single amino acid substitutions in the m2 transmembrane domain which lead to amantadine resistance of these viruses occur at residues 26, 27, 30, 31 or 3...
A novel swine-origin H1N1 influenza A virus has been identified as the cause of the 2009 influenza pandemic in humans. Since then, infections with the pandemic (H1N1) 2009 influenza virus have been documented in a number of animal species. The first known cases of lethal respiratory disease associated with pandemic (H1N1) 2009 influenza virus infection in house pets occurred in domestic cats in...
On May 7, 2009, a national network was organized in the People's Republic of China for the surveillance, reporting, diagnosis, and treatment of influenza A pandemic (H1N1) 2009 virus infection (pandemic [H1N1] 2009). Persons with suspected cases are required to report to the Chinese Center for Disease Control and Prevention and the Ministry of Health within 24 hours; the patient's close contact...
BACKGROUND Between 5 and 25 April 2009, pandemic (H1N1) 2009 caused a substantial, severe outbreak in Mexico, and subsequently developed into the first global pandemic in 41 years. We determined the reproduction number of pandemic (H1N1) 2009 by analyzing the dynamics of the complete case series in Mexico City during this early period. METHODS We analyzed three mutually exclusive datasets fro...
The objective of this study is to describe the clinical and epidemiological characteristics of patients hospitalized in Lithuania who are infected with influenza A(H1N1)pdm09 and to compare pandemic A(H1N1) pdm09 infection with postpandemic. In total, 146 subjects hospitalized with influenza A(H1N1) pdm09 were identified from 2009-2011. There were 53 during the initial pandemic wave in the summ...
