the serious influenza-associated complications among immunodeficient individuals such as those who are infected with human immunodeficiency virus (hiv), highlights the importance of influenza vaccination in these people. therefore, the current study aimed to investigate the antibody responses to influenza vaccine in this group. two hundred subjects were recruited, during autumn 2010 and 2011, t...

objective this is the first report of cns involvement by the new influenza virus (influenza a [h1n1]) in iran. the patient was a 10-year-old boy with chief complaints of fever, malaise, and cranial nerve involvement, resulting in respiratory muscle paralysis and intubation. this shows that the new influenza virus, as well as the seasonal flu, can cause neurologic complications; however, the sev...

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...

We describe the burden of influenza B infections in Italy over a 12-year study period. Influenza A and B viruses co-circulated throughout the period, with numbers of influenza B cases approaching or exceeding those of influenza A during three influenza seasons. Influenza B virus infections led to fewer admissions to an intensive care unit (ICU) and a lower mortality rate than influenza A from 2...

background and aims: infectious bronchitis virus (ibv) causes an acute, highly contagious respiratory and kidney disease of chickens which results in significant economic losses in commercial broilers, layers and breeders. rapid identification of ibv serotypes involved in respiratory complex is a problem in the differential diagnosis. materials and methods: in this study, a single and multiplex...

This report describes the clinical evaluation of a novel fluorescent immunoassay (FIA), Sofia Influenza A+B FIA (Quidel, San Diego, CA), for the rapid detection and differentiation of influenza A and B viruses. A total of 2,047 subjects provided nasal swabs and nasopharyngeal swabs or aspirates. The overall sensitivity and specificity for influenza A virus vs virus culture were 94% and 95%, res...

The burden of human infections with influenza A and B viruses is substantial, and the impact of influenza B virus infections can exceed that of influenza A virus infections in some seasons. Over the past few decades, viruses of two influenza B virus lineages (Victoria and Yamagata) have circulated in humans, and both lineages are now represented in influenza vaccines, as recommended by the Worl...

Acute encephalitis and postinfectious encephalopathy have been reported infrequently in association with influenza A and B virus infections. We report herein a case of a 6-year-old girl with acute influenza B virus encephalitis resulting in neurological sequelae. The diagnosis was made by isolation of influenza B virus from the nasopharynx, seroconversion to influenza B, and reverse transcripti...

Background: Respiratory infections, especially viral infections, are the most prevalent infection affecting Hajj pilgrims. Commonly 3 major human influenza viruses (A/H1N1, A/H3N2, and B) are responsible for these morbidities. The present study was conducted to develop a statistical report on human influenza in Hajj pilgrims.    Methods: Nasal and throat samples were collected from 2...
