In the UK, the proportions of pregnant women who are newly screened positive for hepatitis B, syphilis, and HIV have remained constant since 2010 at about 0.4%, 0.14% and 0.15%, respectively. Estimated prevalence levels among pregnant women for hepatitis B and HIV, including previous diagnoses, were higher at 0.67% and 0.27%.
Pegylated interferon alfa-2a, sold under the brand name Pegasys among others, is medication used to treat hepatitis C and hepatitis B. [3] For hepatitis C it is typically used together with ribavirin and cure rates are between 24 and 92%. [3] [4] For hepatitis B it may be used alone. [5] It is given by injection under the skin.

Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV) that affects the liver; [1] [6] it is a type of viral hepatitis. [7] It can cause both acute and chronic infection . [ 1 ]
Entecavir, sold under the brand name Baraclude, is an antiviral medication used in the treatment of hepatitis B virus infection. [6] In those with both HIV/AIDS and hepatitis B virus antiretroviral medication should also be used. [6] Entecavir is taken by mouth as a tablet or solution. [6]
HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.

Lamivudine has been used for treatment of chronic hepatitis B at a lower dose than for treatment of HIV/AIDS. It improves the seroconversion of e-antigen positive hepatitis B and also improves histology staging of the liver. Long-term use of lamivudine leads to emergence of a resistant hepatitis B virus (YMDD) mutant. [11]
