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 ra...
Background and purpose: Influenza A is an infectious disease caused by RNA viruses of the influenza viruses. Influenza viruses spread around the world in seasonal epidemics. It is estimated to affect %5-%15 of the global population and causing about 250000 to 500000 yearly deaths, rising to millions in some pandemic years. The aim of this study was an epidemiological survey of influenza A v...

Methods: In this cross sectional and questionnaire based study 276 of shiraz general hospitals' personnel were selected b...
respiratory virus infection is a major cause of asthma exacerbation. however, the underlying mechanisms of this exacerbation are unknown. therefore, to determine the mechanisms, we examined the effect of influenza infection in a murine model of asthma.mice were divided into four groups: the phosphate-buffered saline (pbs), house dust mite (hdm), influenza, and hdm/influenza groups. the inf...

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...
Background: Timely response to influenza outbreaks using Influenza like illness (ILI) data is one of the most important priorities for public health authorities. The aim of this study was to evaluate the performance of the Exponentially Weighted Moving Average (EWMA) for timely detection of influenza outbreaks in Iran using simulated approaches from January 2010 to December 2015.

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...
