BACKGROUND In 2009, a pandemic (pdm) influenza A(H1N1) virus infection quickly circulated globally resulting in about 18,000 deaths around the world. In Japan, infected patients accounted for 16% of the total population. The possibility of human-to-human transmission of highly pathogenic novel influenza viruses is becoming a fear for human health and society. METHODOLOGY To address the clinic...
To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004-2005 and 2009-2012, respectively. Genetic and epidemiologic analyses of human and swine influenza viruses indicated 2 events of A(H1N1)pdm09 virus spillover from humans to pigs.
BACKGROUND During the 2009 H1N1 immunization campaign, electronic and hybrid (comprising both electronic and paper components) systems were employed to collect client-level vaccination data in clinics across Canada. Because different systems were used across the country, the 2009 immunization campaign offered an opportunity to study the usability of the various data collection methods. METHOD...
OBJECTIVE To describe clinical and epidemiologic features of 2009 novel influenza A(H1N1) in children. DESIGN Analysis of data obtained from standardized report forms and medical records. SETTING Statewide public health surveillance in California. PARTICIPANTS Three hundred forty-five children who were hospitalized with or died of 2009 novel influenza A(H1N1). MAIN EXPOSURE Laboratory-c...
Much information is available for the 2009 H1N1 influenza immunity response, but little is known about the antibody change in seasonal influenza before and during the novel influenza A pandemic. In this study, we conducted a cross-sectional serological survey of 4 types of major seasonal influenza in March and September 2009 on a full range of age groups, to investigate seasonal influenza immun...
The monthly mean percent positivites for B were 27%, 26%, 29%, and 49% for September, October, November, and December 2013, respectively. We observed 55% positivity for B in January 2014 and 58% for the first 2 weeks of February. Because these percentages were much greater than the national average of <4% [2], we compared the results obtained with the POCT to those obtained with the eSensor res...
Objectives: Influenza is one of the most important emerging and reemerging infectious diseases in the world. The aim of this study is molecular and phylogenetic analyses of the variations in circulating influenza A/H1N1 virus isolates during 2014-2015 in Iran and investigate on the drug resistance conditions in the related Iranian isolates. Material and Methods: Throat samples from Iranian pat...
Background and Objective: Adamantanes, amantadine, and rimantadine have been used for many years for prevention and treatment of influenza virus A infections. These drugs are influenza virus M2 protein inhibitors and some amino acids substitutions in transmembrane portion of this protein cause resistance to them. This study was done for survey of adamantane resistance related nucleotide sequenc...
T cell epitopes have been found to be shared by circulating, seasonal influenza virus strains and the novel pandemic H1N1 influenza infection, but the ability of these common epitopes to provide cross-protection is unknown. We have now directly tested this by examining the ability of live seasonal influenza vaccine (FluMist) to mediate protection against swine-origin H1N1 influenza virus infect...
