Influenza viruses continue to be a major health threat in human and bird populations. The improvements in formulation and production level of the current influenza vaccines are not sufficient to afford complete protection. The continuous antigenic drifts and emergence of endemic and zoonotic strains make influenza vaccine planning difficult. Concern about the emergence of new influenza pandemic...
Background & Aims: Influenza viruses are important causes of mortality and morbidity in children. The aim of this study was to assess the presence of antibodies (IgG) against Influenza A in children in Kerman, Iran. Methods: In a cross-sectional study, 200 children aged 4-14 years referred to Besaat Clinic and Afzalipour hospital for diseases other than influenza were enrolled. Sera were tested...
Influenza is an acute respiratory disease caused by the influenza A or B virus. It often occurs in outbreaks and epidemics worldwide, mainly during the winter season. Significant numbers of influenza virus particles are present in the respiratory secretions of infected persons, so infection can be transmitted by sneezing and coughing via large particle droplets. The mean duration of influenza v...
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...
