| changing epidemiological characteristics of acute viral hepatitis in greece. | we have studied the epidemiological characteristics of acute viral hepatitis (avh) in adult patients admitted to the infectious diseases hospital of athens in 1980. commercially available radioimmunoassays were used for the detection of the hepatitis b surface antigen, its antibody, the antibody to the core of the hepatitis b virus (hbv) and the igg and igm antibody to the hepatitis a virus (hav). hbv was responsible for 59.9%, hav for 20.4% and hepatitis non-a, non-b virus for the remaining 19. ... | 1982 | 6802765 |
| medical and nursing students with suboptimal protective immunity against vaccine-preventable diseases. | medical and nursing students (hereafter referred to as "healthcare students") are at risk of contracting and transmitting infectious diseases in a hospital setting. the aim of our study was to evaluate the vaccination history of healthcare students and their serologic immunity against vaccine-preventable diseases. | 2009 | 19708792 |
| are municipal solid waste collectors at increased risk of hepatitis a virus infection? a greek cross-sectional study. | municipal solid waste collectors are reportedly at risk for hepatitis a virus infection (hav) as an occupational hazard. we aimed to investigate the prevalence and possible risk factors of hav infection among solid waste collectors in a municipality of the broader region of attica, greece. a cross-sectional sero-prevalence study was conducted. fifty (n=50) waste collectors participated in the study (response rate: 95%). the group of municipal waste collectors was compared to a convenient sample ... | 2016 | 28011965 |
