BACKGROUND West Nile virus is a mosquito transmitted virus that can cause disease in humans and horses. A majority of people infected with WNV will have no symptoms or may only experience mild symptoms, such as headaches. About 20% of infected humans develop a flu-like illness characterized by fever; while in the elderly and immunocompromised West Nile virus can cause a more serious neurologic ...

Background & objectives Transfusion-transmitted infections (TTIs) are the major problem associated with blood transfusion. Accurate estimates of risk of TTIs are essential for monitoring the safety of blood supply. The present study was undertaken to determine the percentage of voluntary donors (VDs) and replacement donors (RDs) and also, to estimate and compare the seroprevalence and changing ...

West Nile virus (WNV) is transmitted to humans primarily by infected mosquitoes. However, WNV also can be transmitted through infected blood products or solid organs (1). Since 2003, the U.S. blood supply has been routinely screened for WNV RNA. The Food and Drug Administration (FDA) recommends that blood collection agencies perform WNV nucleic acid testing (NAT) year-round on all blood donatio...

introduction and aims: tt virus (ttv) is a dna virus and is proposed as a potential cause of non-a to e hepatitis. we aimed to investigate, for the first time, the prevalence of ttv in iranian healthy blood donors. materials and methods: three hundred and twelve healthy iranian blood donors were randomly selected and tested for ttv dna by the seminested polymerase chain reaction method. serum a...

objective: in recent years, humman papilomaviruses (hpv) infection is the most common type of sexual trasmitted diseases (std) in majority of countries. it's a significant source of morbidity and mortality worldwide. in this study, we aimed to compare the history of reproductive disease between two groups of iranian women with and without hpv infection through colposcopy precedure. materials an...

Over the past decades, the incidence of transfusion-transmitted diseases has been dramatically reduced. These reductions have been due to a multifocal approach to the collection, processing, and release of blood components. The estimated risks of transfusion-transmitted hepatitis viruses are now extremely small, but the possibility of infections with emerging pathogens always exists because pre...

normal 0 false false false en-us x-none ar-sa background: hepatitis c virus (hcv) is the main causative agent of post-transfusion hepatitis. the virus is distributed worldwide with varying prevalence in different countries, which could easily lead to chronic infections, cirrhosis, and even hepatocellular carcinoma. the aim of this study was to investigate prevalence of hcv infection and its tre...

Blood donations saves the lives of millions of people worldwide, and blood transfusion is essential to the effectiveness of the health care system by supporting modern medicine as its pivotal role in patient interventions (1, 2). new, more sophisticated medical and surgical procedures such as transplant, heart surgery, and trauma or cancer treatment depend highly on blood transfusions in each c...
