Background and Aims: Influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. Vaccination is one of the best ways to prevent infections including influenza. Influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (RNP). A vi...
Abstract Background and Objective: Influenza is an acute respiratory infection caused by Influenza virus with three kinds of A, B and C . This virus spreads througout the world and produce some epidemics with different intensities . This study aimed to determine the prevalence of influenza B in patients reffering to health centers. Material an...
Background and Objective: Influenza is a global epidemic disease that always causes irreparable damage to individuals and countrieschr('39') health, and the amount of research in this area is increasing. The primary purpose this study is to discover the hidden patterns and emerging events of global influenza publications. Materials and Methods: This article is an applied type was done with an ...
background : avian influenza virus (aiv) infection is a major cause of bird and human morbidity and mortality. we aimed to evaluate a specific and sensitive multiplex rt-pcr that can simultaneously detect influenza type a viruses and differentiate the two most important subtypes of avian influenza viruses h7 and h9 subtypes. methods : a multiplex reverse transcriptase-polymerase chain reaction...
Background and Objectives: Iran, like most other countries in the world, is always threatened with global epidemics and pandemics of influenza. The purpose of this study was to review the influenza surveillance system in Iran. Methods: Data of this study were obtained from the surveillance system of the Center for Communicable Disease Control, the review of records, documents, books and pub...
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...
background influenza is a world-wide public health concern. it is one of the most important viral causes of acute respiratory illness, affecting all age groups, recurring several times during a lifetime. we assessed the antibody titers after vaccination against influenza among hiv-infected patients and health care workers (hcws). patients and methods during this before-after study, the antibody...
The spread of influenza viruses in multiple bird and mammalian species is a worldwide serious threat to human and animal populations' health and raise major concern for ongoing pandemic in humans. Direct transmission of the avian viruses which have sialic acid specific receptors similar to human influenza viruses are a warning to the emergence of a new mutant strain that is likely to share mole...
background and purpose: pregnant women are at a higher risk of influenza infection, and influenza vaccination is recommended for these women to reduce the associated complications. this study aimed to determine the knowledge and practice about influenza vaccination and identify the factors influencing compliance with influenza immunization among pregnant women. methods: this cross-sectional stu...
results out of 253 cases confirmed for influenza a (h1n1), 9 women and 11men had died. amongst these cases the minimum and maximum age was3.5 and90 years, respectively. also, from the 20 confirmed cases of influenza a (h1n1) that had died, 16 cases had at least one underlying disease. conclusions there was no significant association between mortality of confirmed cases of influenza a (h1n1) and...
