Seroprevalence and risk assessment of viral hepatitis E infection in a group of exposed persons from Republic of Moldova.

Introduction: Viral hepatitis E is considered to be an important issue for public health in developing countries. The aim of the present study is to evaluate morbidity and risk factors in occupationally exposed groups such as people working on sausage production.

Methodology: Seroprevalence of HEV (hepatitis E virus) and risk factors to infection were determined in a cross-sectional study of two groups of populations: people working on sausage production (n = 70) and persons without occupational exposure (people working in the textile industry n = 70) in Moldova, a country without reported cases of hepatitis E.

Hepatitis B, C and D virus genotypes detected in HBsAg- or anti-HCV-positive people from the Republic of Moldova.

In the Republic of Moldova, little is known about hepatitis B, C and D virus (HBV, HCV, HDV) genotypes, although the genetic variant may influence the course and outcome of disease. For HBV genotyping, 301 hepatitis B surface antigen (HBsAg)-positive sera collected in 2010 and 2011 from drug users, prison inmates, commercial sex workers, and the general population in different geographical regions were investigated. The 31 HBsAg-positive sera collected in 2011 were also tested for HDV.

Epidemiology of hepatitis C in the Republic of Moldova: achievements and remaining challenges in prevention and control.

Viral hepatitis, especially those with parenteral and sexual transmission, still remain a major problem of public health, both globally and for the Republic of Moldova, due to wide spreading, endemicity, increased morbidity and mortality and high rate of invalidity following the chronization of infection, but usually neglected by population and public health authorities. This paper describes the epidemiology and preventive and control measures of hepatitis C in Moldova. Epidemiological analysis of the surveillance data on hepatitis C incidence in the Republic of Moldova was conducted.

Epidemiology of hepatitis B virus infection in the Republic of Moldova.

Background: The Republic of Moldova is considered a high endemic country with hepatitis B virus infection having a prevalence of AgHBs of 8% and higher. This paper describes the epidemic process and changes in the acute hepatitis B incidence in Moldova from 1966 until 2006. The objective was to evaluate the prophylactic measures that have led to the decline in the epidemic process of this infection.
