The aim of the study was to determine the prevalence of hepatitis E virus (HEV) infection among individuals at high risk of transmission of non-A, non-B hepatitis or sexually transmitted diseases (STDs), and to evaluate whether they have an increased risk of exposure to HEV. Serum samples from 125 thalassemia patients, 300 intravenous drug users, 420(More)

Water contaminated with hexavalent chromium is a worldwide problem, making this a question of significant public health importance. METHODS We conducted an ecological mortality study within the Oinofita region of(More)
In this article, three alternative Bayesian hierarchical latent factor models are described for spatially and temporally correlated multivariate health data. The fundamentals of factor analysis with ideas of space- time disease mapping to provide a flexible framework for the joint analysis of multiple-related diseases in space and time with a view to(More)
BACKGROUND/AIMS The aim of this study was to determine the frequency of hepatitis E virus infection in a cohort of patients with acute non-A, non-B hepatitis in Greece. METHODS Serial serum samples of 198 patients with acute non-A, non-B hepatitis and a single serum specimen from 316 healthy subjects were tested for IgG and IgM antibodies to hepatitis E(More)
in Mexico (6) and the United States (7). In the United States, several pregnant women died, and the hospitalization rate for pregnant women was 4× higher than for the general population (8). Despite a fairly high birth rate on Reunion Island (19 births/1,000 population), our small series does not support these fi ndings. During the epidemic (July 20–(More)
BACKGROUND The aim of this study was to determine the prevalence of hepatitis E virus (HEV) infection among patients undergoing haemodialysis (HD) and to evaluate whether chronic haemodialysis is associated with an increased risk of HEV infection. METHODS Serum samples from 420 HD patients and 316 healthy volunteers were tested for IgG and IgM antibodies(More)
