Strategies implemented to prevent transmission of infections by blood transfusion have been very successful. Despite this, the risk of infectious donations entering the blood supply and transmitting infection to the recipients of blood components and blood products is continually under scrutiny. In order to assess the risks and consequences of transfusion transmitted infections the characterist...

Infection transmission systems circulate infection through complex contact patterns related to both contact patterns and patterns of factors that affect the risk of transmission given contact. The nonlinear dynamics of infection transmission cause these patterns to make big differences in population infection levels. A science of infection transmission system analysis is needed to focus on thos...

We report the pregnancy outcome and clinical and laboratory findings in infants born to women with chikungunya infection during pregnancy. There was evidence of vertical transmission and poor pregnancy outcome in some cases.

Mass antibiotic treatment and facial cleanliness are central to WHO's strategy for the elimination of blindness caused by trachoma. Recent studies have highlighted the heterogeneous response of communities to mass treatment and the complex relation between infection with Chlamydia trachomatis and clinical disease. It is important to be able to explain these findings to predict and maximise the ...

the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

OBJECTIVES HIV 'treatment as prevention' (TasP) describes early treatment of HIV-infected patients intended to reduce viral load and transmission. Crucial assumptions for estimating TasP's effectiveness are the underlying estimates of transmission risk. We aimed to determine transmission risk during primary infection, and describe the relation of HIV transmission risk to viral load. DESIGN A ...

800x600 background : hepatitis b and c infections have remained major global health burdens during the most recent century. the viral agents responsible for these diseases share common modes of transmission with human immunodeficiency virus (hiv) such as needle-sharing in iv drug abusers. coinfection of hepatitis b or c with hiv increases the rate of progression of chronic liver disease. given ...
