Maternal antiviral treatment in highly viremic women can reduce the risk of IF. While hepatitis A and hepatitis B both affect the liver and have similar symptoms, they are different viruses. The hepatitis C virus can live outside the body in some circumstances, but it is unusual to contract the virus this way. Hepatitis B virus (HBV) infects more than 300 million people worldwide and is a common cause of liver disease and liver cancer. Maternal HBV DNA quantification during pregnancy allows the assessment of the risk of newborn immunoprophylaxis failure (IF). A sexually transmitted infection (STI) is defined as an infection that results from transmission of a pathogenic organism by sexual contact (i.e. The risk of MTCT is dramatically reduced by timely neonatal HBV vaccination and the administration of hepatitis B immunoglobulin after birth in high-risk infants. In chronically infected patients, an elevated serum hepatitis B virus DNA concentration is the main risk factor. Vaccination effectively prevents infection and chronic hepatitis B virus carriage. It is acquired at birth or later via person-to-person transmission. Mother-to-child transmission (MTCT) during pregnancy is the leading form of transmission in endemic populations, and its interruption is thus crucial as the initial step in the elimination of HBV infection, notwithstanding the availability of potent antiviral medications. Chronic hepatitis B virus infection is a global public health threat that causes considerable liver-related morbidity and mortality. Approximately 30 of people newly infected with HBV do not know how they contracted. Therefore, HCV infections may be acquired via the following means: Intravenous drug. The truth is that transmission of HBV can sometimes occur in unusual ways. Patients with end-stage renal disease are at risk for contracting hepatitis B virus (HBV) because of their exposure to blood products and compromised immune status. Hepatitis B virus (HBV) infection is the commonest cause of chronic hepatitis, with an estimated global prevalence of 3.5%, and which leads to significant morbidity and mortality. HCV is largely transmitted parenterally, i.e. ![]()
