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...
Pandemic influenza A (H1N1) 2009 (pandemic H1N1) is spreading throughout the planet. It has become the dominant strain in the Southern Hemisphere, where the influenza season has now ended. Here, on the basis of reported case clusters in the United States, we estimated the household secondary attack rate for pandemic H1N1 to be 27.3% [95% confidence interval (CI) from 12.2% to 50.5%]. From a sch...
In this report, we describe the occurrence of two novel swine influenza viruses (SIVs) in pigs in Argentina. These viruses are the result of two independent reassortment events between the H1N1 pandemic influenza virus (H1N1pdm) and human-like SIVs, showing the constant evolution of influenza viruses at the human-swine interface and the potential health risk of H1N1pdm as it appears to be maint...
The purpose of this study was to understand the geographic extent, risk factors, and attack rate of the 2009 pandemic influenza A (H1N1) virus [A(H1N1)pdm09] infection in Shandong Province, China and to identify the influencing factors. A randomized serological survey of A(H1N1)pdm09 infection was carried out in August and September 2010. A total of 4,549 participants involved in the survey ...
The H1N1 virus is one of the highly contagious strains that leads to epidemic influenza every year in winter. In this outbreak sometimes rare complications of this infection occur. This report presents a rare case of encephalitis caused by H1N1 virus in a 52-year old man. After a day fever and flu like symptoms the patient was admitted in hospital due to decreased level of consciousness. ...
Background: Respiratory virus infections represent a major public health problem because of their worldwide occurrence, ease of spread in the community and considerable morbidity and mortality. They are one of the most common reasons for hospitalization of children under the age of six. In some cases, infection with two different viruses increase the severity of disease which lead to the h...
background: a new pandemic influenza a (h1n1) emerged in april 2009, causing considerable morbidity and mortality. since mutations in the haemagglutinin (ha) may influence the antigenicity and pathogenicity of the virus, continued epidemiological and molecular characterization for the effective control of pandemic flu and developing of more appropriate vaccine is crucial. objective: to monitor ...
eMJA RAPID ONLINE PUBLICATION UPDATED 13 AUGUST 2009 inc inf an S e the initial reports of H1N1 influenza (human swine luenza; caused by influenza A/2009/H1N1/swl) in Mexico d the United States in mid April 2009, many thousands of cases have been reported worldwide. At the time of writing, community transmission is becoming established in many areas in Australia, but the number of reported case...
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...
conclusions the prevalence of pandemic influenza viruses in recent years has caused financial losses as well as mortalities around the world. this shows the importance of the rapid diagnosis of common serotypes in our society. using real-time rt-pcr is recommended for the early diagnosis and the rapid identification of the individuals infected with pandemic influenza virus. background timely di...
