BACKGROUND AND OBJECTIVES We conducted a longitudinal prospective study to assess the eligibility to blood donation of donors with 'minor' risk factors (i.e. minor surgery, professional exposure, cohabitation with 'high risk' people, occasional use of light drugs) or 'medium' risk factors for human immuno-deficiency virus (HIV) infection (i.e. casual sexual relationship, multiple heterosexual e...

OBJECTIVES To identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM), focusing on potential sexual, nosocomial, and other non-sexual determinants. BACKGROUND Outbreaks of hepatitis C virus (HCV) infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV p...

BACKGROUND AND AIMS A better understanding of the relationship of homocysteine with cardiovascular risk factors is needed. The objectives of this study were to assess the serum level of homocysteine in HIV-infected patients and to analyse the possible association of increased levels of the amino acid with cardiovascular risk factors, demographic and clinical characteristics of participants. M...

BACKGROUND Infant immunization against hepatitis B began in Uganda in 2002. OBJECTIVE To determine the baseline prevalence of hepatitis B virus (HBV) infection and explore risk factors. METHODS A hepatitis B prevalence study was nested in the 2005 national HIV/AIDS serobehavioural survey. Demographic characteristics and risk factors were explored by questionnaire. One third of blood specime...

OBJECTIVE To estimate the prevalence of HIV, HCV, HBV and co-infection with 2 or 3 viruses and evaluate risk factors among injecting drug users (IDUs) in Yunnan province, China. METHODS 2080 IDUs were recruited from 5 regions of Yunnan Province, China to detect the infection status of HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV). Statistical analysis was performed to evaluate risk...

OBJECTIVES Biological and behavioural surveillance of HIV and sexually transmitted infections (STIs) among populations at highest risk have been used to monitor trends in prevalence and in risk behaviours. Sex work in Panama is regulated through registration with the Social Hygiene Programme, Ministry of Health. We estimated prevalence of HIV and STIs, and factors associated with active syphili...

introduction : regular blood transfusions for patients with thalassemia major have improved their overall survival, but carry a definite risk of being infected with blood born viruses especially hepatitis b and c. nowadays, it has remained as main health concern about these patients. in this study, we tried to define the prevalence rate of hepatitis b and c and survey the related risk factors a...

conclusions the risk of symptomatic hav infection is considerable in adolescents of all studied provinces; thus, universal hav vaccination is recommended for all adolescents, regardless of their socioeconomic level. however, the risk is higher in some provinces, which seem to be transitioning from intermediate to low endemicity. results the weighted prevalence of hav varied significantly across...

Occupational exposure to a range of pathogens represents a serious risk to anaesthetists. The risk of transmission of blood-borne pathogens, such as human immunodeficiency virus (HIV) and hepatitis B and C, are well known, but occupational exposure also includes airborne pathogens such as tuberculosis. The risk of occupational infection with a blood-borne pathogen is proportional to three factors:
