Journal ArticleDOI
Assays for the detection of recent infections with human immunodeficiency virus type 1.
TL;DR: Recommendations for laboratory quality systems that will improve the efficiency of STARHS testing, reproducibility of results and reliability of incidence estimates are outlined.
Journal ArticleDOI
Prevalence of, and risk factors for, HIV, hepatitis B and C infections among men who inject image and performance enhancing drugs: a cross-sectional study

TL;DR: HIV prevalence in this, the largest study of blood-borne viruses among IPED injectors, was similar to that among injectors of psychoactive drugs, indicating a need for targeted interventions.
Journal ArticleDOI
Factors associated with deaths due to COVID-19 versus other causes: population-based cohort analysis of UK primary care data and linked national death registrations within the OpenSAFELY platform

TL;DR: In this paper, the authors investigated how specific factors are differentially associated with COVID-19 mortality as compared to mortality from causes other than COVID19, and found that older age was more strongly associated with death than non-COVID death, as was male sex, deprivation, obesity, and some comorbidities.
Journal ArticleDOI
Measuring the incidence, prevalence and genetic relatedness of hepatitis C infections among a community recruited sample of injecting drug users, using dried blood spots.

TL;DR: Public health surveillance of HCV among IDUs could be enhanced through the collection of DBS samples with appropriate recruitment approaches, and would allow surveillance to inform development of harm reduction interventions, and the international evidence base for these.
Journal ArticleDOI
Role of viruses in febrile convulsions.
TL;DR: The results suggest that a febrile convulsion could be a response to invasion of the blood stream or central nervous system by a micro-organism which is usually a virus.
