Relatively little is known about the burden of influenza in tropical countries. The seroprevalence of pandemic influenza A (H1N1) 2009, seasonal H1N1 and H3N2 was determined in Kuala Lumpur, Malaysia. Pre- and post-pandemic residual laboratory sera were tested by hemagglutination-inhibition. The seroprevalence of A(H1N1)pdm09 increased from 3.7% pre-pandemic to 21.9% post-pandemic, giving an ov...
The study aimed to determine factors influencing the uptake of 2009 H1N1 influenza vaccine in a multiethnic Asian population. Population-based, cross-sectional survey was conducted between October and December 2009. Approximately 70% of overall participants indicated willingness to be vaccinated against the 2009 H1N1 influenza. Participants who indicated positive intention to vaccinate against ...
BACKGROUND The sensitivity of rapid influenza diagnostic test (RIDT) of children with influenza-like illness (ILI) remains low. OBJECTIVE We compare the parameters between pandemic A(H1N1) 2009 influenza with negative RIDT and ILI not H1N1 for improving the low sensitivity of RIDT for children with ILI. METHODS In a cohort of consecutive laboratory-confirmed H1N1 influenza, we identified 15...
سابقه و هدف: آنفلوآنزای (a (h1n1 اولین جهانگیری آنفلوآنزا در قرن حاضر می باشد که کشور ایران را نیز در برگرفت و اولین مورد آن در کاشان اواخر تیر ماه 1388 اتفاق افتاد. این پژوهش با هدف توصیف گام های گسترش بیماری آنفلوانزای (a (h1n1 در شهرستان های کاشان و آران و بیدگل، در سال 1388، و تشریح مشخصات موارد بروز و فوت انجام شد. مواد و روش ها: این مطالعه از نوع بررسی مجموعه موارد قطعی آنفلوآنزای (a (h1n...
Influenza A H1N1/2009 virus that emerged from swine rapidly replaced the previous seasonal H1N1 virus. Although the early emergence and diversification of H1N1/2009 is well characterized, the ongoing evolutionary and global transmission dynamics of the virus remain poorly investigated. To address this we analyse >3,000 H1N1/2009 genomes, including 214 full genomes generated from our surveillanc...
(H1N1) became resistant to both oseltamivir and amantadine in a short span of 1 month. Oseltamivir-resistant A/Brisbane/59/2007-like clade 2B virus that had reassorted with A/Hong Kong/2652/2006-like clade 2C virus had apparently spread in the community and to other regions of the world. The possibility of reassortment with pandemic (H1N1) 2009 virus is a major concern. Resistance to oseltamivi...
The spring of 2009 witnessed the emergence of a novel influenza A(H1N1) virus resulting in the first influenza pandemic since 1968. In autumn of 2010, the 2009 novel H1N1 influenza strain re-emerged. We performed a retrospective time-series analysis of all patients with laboratory-confirmed H1N1 influenza who presented to our institution during 2009. Cases of influenza were assembled into 3-day...
H1N1 viruses in which all gene segments are of avian origin are the most frequent cause of influenza pandemics in humans; therefore, we examined the disease-causing potential of 31 avian H1N1 isolates of American lineage in DBA/2J mice. Thirty of 31 isolates were very virulent, causing respiratory tract infection; 22 of 31 resulted in fecal shedding; and 10 of 31 were as pathogenic as the pande...
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...
مقدمه: ضایعات خاموش مغزی که در ام آر آی مغزی دیده می شوند نه تنها در افرادی که برای اولین بار دچار سکته می شوند یافت می گردند بلکه در افراد مسن سالم نیز دیده می شوند. برخی از مطالعات بر نقش احتمالی ضایعات خاموش ساب کورتیکال در موارد سکته مغزی ایسکمیک تأکید می کنند. هدف از این مطالعه تعیین فراوانی این ضایعات در بیمارانی که برای اولین بار دچار سکته مغزی ایسکمیک شده بودند، می باشد. روش کار: در این...
