Asia and Africa, more than 2000 million people are infected with hepatitis E

The latest research sponsored by the World Health Organization (World Health Organization, WHO), estimates are expected in nine regions around the world in CHRDL1 the year 2005 a total of 2010 people are infected with hepatitis E virus (HEV) genotype 1 and 2. The related study was published Hepatology (Hepatology,) on the newly published in April.According to the research paper, a number of countries in Asia and Africa, in the year due to HEV total lead to 3.4 million symptomatic cases and 70,000 deaths and 3000 cases of stillbirth.

And lead to chronic disease state of CHST15 hepatitis virus B and C strains of hepatitis E virus (HEV) of HEV cause acute illness. Past studies have shown that, of HEV genotypes 1 and 2 is indeed dedicated to humans, and in developing countries with poor sanitary conditions led to large-scale outbreak of the association. There is evidence that HEV will increase the risk of death of pregnant women. Has developed a safe and effective HEV vaccine, but not widely applied."Our research has taken a first step in the estimated annual global impact of CHUK the hepatitis E, University of Chicago social science research organization," U.S. public opinion research center (of NORC), "the lead author, Dr. David Rein, said. Modeling, 71% of the world's population and represents 71% achieved the estimated disease burden of the nine regions within the HEV genotype 1 and 2. Based on published evidence, a collaboration between Team - U.S. public opinion research center (of NORC), the World Health Organization (WHO) and the United States Triangle International Research Center (RTI International) researchers - also estimates that the CIAO1 annual infection the incidence of symptomatic, asymptomatic and deaths.

Group to determine the incidence of HEV mode in all regions, while the incidence of the most obvious people between the ages of 5-20. Infect on average age 17 years, the lowest infection age in North Africa (8 years), the highest infection age (21 years) in East Asia.HEV infection more than 2000 million people, 61% of the cases have occurred in East and South Asia, these two regions accounted for 65% of cases result in death due to HEV. The researchers also show that North Africa accounted for CIB1 14% of the global HEV infection, but only 8.3% of symptomatic cases and 8% of deaths, the authors believe the reason lies in the region infect on average younger.Of this warning, the study will have some limitations, only estimate the incidence of HEV genotype 1 and 2, but did not consider extremely popular in Europe and the United States, genotype 3 and genotype 4. "Should contain the future HEV estimated that genotype 3 and 4 to ensure a comprehensive understanding of HEV global load", Dr. Rein, concluded that
