Occult infection with hepatitis B virus (HBV) is a type of chronic HBV infection that is characterized by the absence of a detectable hepatitis B surface antigen in the blood and by very low levels of HBV DNA in the blood and liver. The mechanisms leading to occult HBV infection remain poorly understood but include possible genetic mutations and deletions. Recently, it has been shown that HBV has CpG islands that are methylated, raising the possibility that epigenetic changes may also be important.
