Homeless people are usually prone to be infected with multiple infectious diseases such as human immunodeficiency virus, hepatitis B virus, and hepatitis C virus, as well as syphilis. In this cross-sectional study, using a questionnaire and enzyme-linked immunosorbant assay, we evaluated the seroprevalance of hepatitis B and C viruses, human immunodeficiency virus, and syphilis, as well as thei...

BACKGROUND Viral hepatitis with various forms of acute and chronic liver disease as potential and ultimately fatal sequelae presents a public health problem worldwide. METHODS Recent published reports on the global epidemiology and prophylaxis of viral hepatitis were reviewed. RESULTS With the advances in novel technologies, eight distinct types of hepatitis virus have been described: Hepat...

Reprinted with permission from CME August 2005 Vol. 23 No. 8 M any viruses can infect the liver, but are usually not able to enter hepatocytes due to certain barriers such as the activity of Kupffer cells. Viruses such as Epstein-Barr virus and cytomegalovirus frequently cause hepatitis as part of a systemic illness, but this is seldom the main symptom. The typical hepatitis virus is able to en...

results the results of this study indicated that the overall hepatitis b vaccine acceptance rate was acceptably high. among all, 53.5% correctly identified that a vaccine to prevent hepatitis b virus infection had been available, 15% had a negative opinion, and 31.5% were neutral. the rations of all three doses of vaccination were 69.3%. conclusions among the respondents, 87% were currently mar...

In the early 1990’s, occasional incidents of transmission of enveloped viruses (hepatitis B (HBV) and C viruses (HCV)) and other blood-borne viruses, including hepatitis A virus (HAV) occurred with plasma-derived medicinal products. As a result, the effectiveness of processes for inactivation/ removal of enveloped viruses was increased. In addition, the Committee on Proprietary Medicinal Produc...

WHY IMMUNE ESCAPE IS IMPORTANT Knowledge of the molecular virology of the hepatitis viruses and the responses they elicit has emphasised the importance of host immunity in resolving infection and mediating liver damage. Many viruses cause cytolytic infections in which viral replication occurs at the expense of host cell viability. However this is a shortsighted strategy for the virus as it prov...

results analyzing of collected data resulted in the wrapping up the hepatitis virus detection methods in separate sections including 1) immunological methods such as enzyme immunoassay (eia), radio-immunoassay (ria) immuno-chromatographic assay (ica), and immuno-chemiluminescence 2) molecular approaches including non-amplification and amplification based methods, and finally 3) advanced biosens...

Knowledge about hepatotropic viruses is crucial for pediatricians because of the high prevalence of viral hepatitis during childhood. The multiplicity of hepatotropic viruses, the spectrum of acute and chronic infections, and the sequels of viral hepatitis result in a need for physicians to better understand the clinical and epidemiological context of patients with viral hepatitis, as well as t...

BACKGROUND Injecting drug users are at high risk of acquiring blood-borne infections. Ireland has had a harm reduction policy of methadone maintenance and needle exchange since 1992. AIM To estimate prevalence of hepatitis B, hepatitis C and HIV infection and appropriate uptake of hepatitis B vaccine in methadone attendees and to make recommendations for a simple record-based surveillance sys...
