Hepatitis B prevalence, risk factors, infection awareness and disease knowledge among inmates: a cross-sectional study in Switzerland's largest pre-trial prison

Abstract

Hepatitis B virus (HBV) is a major health concern in prison, but data are scarce in European prisons. This study aims to measure the prevalence of HBV infection, risk factors, awareness about infection, and HBV knowledge among inmates in Switzerland's largest pre-trial prison. Serological blood tests (HBsAg, anti-HBs, and anti-HBc) and a standardized socio-demographic and sexual health survey were offered to consenting prisoners in 2009 and 2011. HBV knowledge was assessed using a standardized questionnaire among participants recruited in 2009. A total of 273 male participants were included in the study (116 participants answered the HBV knowledge survey), with 38.1% originating from Eastern Europe, 28.2% from sub-Saharan Africa, 14.3% from North Africa, and 9.5% from Latin America. The prevalence of anti-HBc (resolved/chronic infection) was 38.2% and the prevalence of HBsAg (chronic infection) was 5.9%; 14% of participants had vaccine-acquired immunity (anti-HBs positive/anti-HBc negative). We estimated that 15.5% of people living in Geneva having chronic infection go through the Geneva's prison. Region of origin was significantly associated with chronic/resolved HBV infection (P < 0.001): 72.2% of participants from sub-Sahara...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
