Abstract Background and objectives: Influenza virus is the sixth cause of death in the world. We cannot differentiate it from other respiratory viruses upon clinical signs alone. This study was aimed at determining the frequency of influenza A&B antigen in pharyngeal secretion of children with upper Respiratory Infection (URI). Materials and methods: This cross sectional -descriptive study was ...
Background: Both influenza A virus (IAV) and respiratory syncytial virus (RSV) cause acute respiratory infection (ARI) in infants and young children. This study was conducted to determine Influenza A virus and its co infection with RSV among the hospitalized children with ARI. Methods: A total of 153 throat samples of the hospitalized young children aged between below one year and 5 years with...
Introduction: Influenza is an infectious and severe respiratory disease. It is one of the major problems of public health. In order to determine the spatial distribution and areas with over-expected of a disease including influenza, it can be effective in identifying environmental hazards and fair distribution of health services. In this study, the geographical distribution of the influenza and...
Background: Influenza viruses are one of the most important etiological agents of res-piratory disease in humans and cause epidemics and pandemics with substantial mor-bidity and mortality worldwide. Vaccination and antiviral treatments are the sole and essential way for the prevention and control of influenza infection. During an influenza epidemic before the production of effective vaccine, a...
abstract : avian influenza virus (aiv) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. although the risk of infection with avian influenza virus (aiv) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the rapid ide...
background: both influenza a virus (iav) and respiratory syncytial virus (rsv) cause acute respiratory infection (ari) in infants and young children. this study was conducted to determine influenza a virus and its co infection with rsv among the hospitalized children with ari. methods: a total of 153 throat samples of the hospitalized young children aged between below one year and 5 years with ...
background emergence of a novel swine-origin influenza a (h1n1) pandemic since 2009 attracted the attention of scientists to characterize epidemiological features and clinical manifestations of this disease in comparison to seasonal flu in different parts of the world. objectives the goal of this investigation was to compare these features in confirmed cases of swine-origin influenza a (h1n1) a...
Background and purpose: Influenza is a respiratory infection that annually affects 5-15% of the global population. Influenza A/H1N1 is the most virulent human pathogens that results in a more severe disease and was first reported in 2009. The aim of this study was to investigate the epidemiology of influenza A/H1N1 in patients referring to several hospitals in North of Iran during 2009-2011. ...
Background: Influenza virus is a major infectious pathogen of the respiratory system causing a high degree of morbidity and mortality annually. The worldwide vaccines are decided and produced annually by World Health Organization and licensed companies based on the samples collected from all over the world. The aim of this study was to determine phylogenecity and heterogenecity of the circulati...
Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...
