Silver nanoparticles have demonstrated efficient inhibitory activities against human immunodeficiency virus (HIV) and hepatitis B virus (HBV). However, the effects of silver nanoparticles against H1N1 influenza A virus remain unexplored. In this study, the interaction of silver nanoparticles with H1N1 influenza A virus was investigated. Silver nanoparticles with mean particle diameters of 10nm ...
Background and Objective: Novel H1N1 influenza virus is a unique type of influenza virus which has developed due to abrupt structural alterations (Shift and Drift). This virus can lead to a pandemic disease. Since manifestations and severity of this disease may be affected by environmental, cultural and economic factors, therefore this epidemiological and regional study was carried out to revea...
The novel influenza A (H1N1) virus is now rapidly spreading across the world. Early detection is one of the most effective measures to prevent further transmission of the virus. 4 sets of proprietary primers and probes designed for detection of influenza A viruses (InfA), human and swine H1N1 viruses (SH1), the novel H1N1 viruses (NH1) and RNaseP gene (RP) respectively were pooled together in a...
BACKGROUND We compared the clinical effectiveness of oseltamivir and zanamivir in children with influenza A (H1N1) virus, influenza A (H3N2) virus, and influenza B virus infections. METHODS Total febrile period and the duration of fever after the start of treatment were compared between an oseltamivir-treated group (mean age, 8.9 years; range, 4.0-15.9 years) and a zanamivir-treated group (me...
Background and Aims: Influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. Vaccination is one of the best ways to prevent infections including influenza. Influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (RNP). A vi...
CONTEXT Preventing nosocomial transmission of influenza is essential to reduce the morbidity and mortality associated with this infection. In October 2009, an outbreak of the 2009 influenza A (H1N1) virus occurred in a hematology ward of a children's hospital over a 21-day period and involved two patients and four healthcare workers. OBJECTIVE To investigate nosocomial transmission of the 200...
Pandemic H1N1/2009 influenza virus, derived from a reassortment of avian, human, and swine influenza viruses, possesses a unique gene segment combination that had not been detected previously in animal and human populations. Whether such a gene combination could result in the pathogenicity and transmission as H1N1/2009 virus remains unclear. In the present study, we used reverse genetics to con...
BACKGROUND Acute respiratory infections are a leading cause of morbidity and mortality worldwide. Starting in 2009, pandemic influenza A(H1N1) 2009 virus has become one of the leading respiratory pathogens worldwide. However, the overall impact of this virus as a cause of mortality has not been clearly defined. OBJECTIVES To determine the impact of pandemic influenza A(H1N1) 2009 on mortality...
Simple and rapid diagnosis of influenza is useful for making treatment decisions in the clinical setting. Although many influenza rapid diagnostic tests (IRDTs) are available for the detection of seasonal influenza virus infections, their sensitivity for other viruses, such as H5N1 viruses and the recently emerged swine origin pandemic (H1N1) 2009 virus, remains largely unknown. Here, we examin...
Since the beginning of January 2008 sporadic cases of infections in humans caused by influenza A (H1N1) virusresistant to available anti-influenza drugs have been reported worldwide [1,2]. The World Health Organization (WHO) in its report published on 18 March 2009 indicated that during weeks 1-4 (28 December 08-24 January 09), the level of overall influenza activity in the world increased. Dur...
