Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...

  Background and purpose: Recently, due to the reduction of hepatitis A in Iran there are people with low or no Hepatitis A Virus- Antibody (HAV-Ab), therefore, people at Arbaeen Pilgrimage are at risk for hepatitis A. This study aimed at examining HAV-Ab in pilgrims traveling from Mazandaran province, Iran to Karbala in 2018. Materials and methods: This cross-sectional study was performed in...
