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...
To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004-2005 and 2009-2012, respectively. Genetic and epidemiologic analyses of human and swine influenza viruses indicated 2 events of A(H1N1)pdm09 virus spillover from humans to pigs.
BACKGROUND During the 2009 H1N1 immunization campaign, electronic and hybrid (comprising both electronic and paper components) systems were employed to collect client-level vaccination data in clinics across Canada. Because different systems were used across the country, the 2009 immunization campaign offered an opportunity to study the usability of the various data collection methods. METHOD...
The monthly mean percent positivites for B were 27%, 26%, 29%, and 49% for September, October, November, and December 2013, respectively. We observed 55% positivity for B in January 2014 and 58% for the first 2 weeks of February. Because these percentages were much greater than the national average of <4% [2], we compared the results obtained with the POCT to those obtained with the eSensor res...
Objectives: Influenza is one of the most important emerging and reemerging infectious diseases in the world. The aim of this study is molecular and phylogenetic analyses of the variations in circulating influenza A/H1N1 virus isolates during 2014-2015 in Iran and investigate on the drug resistance conditions in the related Iranian isolates. Material and Methods: Throat samples from Iranian pat...
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...
OBJECTIVE To evaluate ascertainment of the onset of community transmission of influenza A/H1N1 2009 (swine flu) in England during the earliest phase of the epidemic through comparing data from two surveillance systems. DESIGN Cross sectional opportunistic survey. STUDY SAMPLES Results from self samples by consenting patients who had called the NHS Direct telephone health line with cold or f...
BACKGROUND We set out to identify the level of previous exposure to influenza A (H1N1) in unvaccinated healthcare workers (HCWs) at the peak of the pandemic outbreak in the UK, with control samples collected prior to the outbreak. METHODS Cross-sectional study (seroprevalence assessed before and at pandemic peak, with questionnaire data collected at peak of outbreak) in HCWs in Scotland. RE...
