background and aims: hepatitis d virus (hdv) can infect human population either as a superinfection or concurrent hepatitis b virus (hbv) infection. it is expected that presence of hdv infection is more prevalent in endemic hbv areas. overall 5% of iranian general populations are chronic hbv carriers. the aim of this study was to determine the seroprevalence of hdv and its clinical impact in a ...

background china is a country with a high prevalence of hepatitis b. as a special population, migrant workers are more vulnerable to hepatitis b. objectives the present study was conducted to gain insight into the prevalence of hepatitis b and knowledge about hepatitis b among migrant workers in shandong province, china, as well as to explore a series of strategies for preventing and controllin...

Hepatitis B is a global acute and chronic life-threatening liver infection caused by the hepatitis virus. During cadaveric dissection, clinical rotations, autopsy posting, medical students get exposed to patients’ blood body fluids, which increases risk of infection. can be prevented vaccines that are safe, easily available, effective, however many still unvaccinated. This results in need for a...

conclusions in this city, a great proportion of children are susceptible to hepatitis a and it’s complications at an older age. this decrease in seropositivity may be caused by elevated hygien level. according to our results hepatitis a vaccination is recommended at early childhood such as that of other regions where low prevalence of hepatitis a infection is found. patients and methods this cr...

BACKGROUND AND AIMS Recent studies have shown that the age-specific seroprevalence of H pylori infection parallels hepatitis A (HAV), suggesting similar modes of transmission. The aim of this study was to investigate the seroepidemiology of H pylori and HAV in the same setting. PATIENTS A sample of 705 resident subjects (273 men, age range 1-87 years, median 50) who attended the outpatient me...

Background and Aims: Co-infection of hepatitis E virus (HEV) in chronic hepatitis C virus (HCV) infected patients can develop and increase liver disease and hepatic complications in the world. The purpose of this study was to assess the prevalence of HEV infection in patients suffering from chronic HCV infection. Materials and Methods: Cross-sectional study testing anti-HEV antibodies in serum...

‎Hepatitis B virus (HBV) infection is a major public health problem in the world today‎. ‎A mathematical model is formulated to describe the spread of hepatitis B‎, ‎which can be controlled by vaccination as well as treatment‎. ‎We study the dynamical behavior of the system with fixed control for both vaccination and treatment‎. ‎The results shows that the dynamics of the model is completely de...

objective: occult hepatitis b infection is a form of hepatitis in which despite of absence of detectable hbsag, hbv-dna is present in peripheral blood of patients. this clinical form of b hepatitis creates some problems for the iranian blood transfusion services. therefore, the aim of this study was the evaluation of status of occult hepatitis b infection in the rafsanjanese blood donors. mate...
