4-8 weeks: The incubation period of the hepatitis B virus to developing symptoms is 75 days on average, but can vary from 30 to 180 days. The virus may be detected 30 to 60 days after infection. In the setting of acute HBV infection, HBsAg typically becomes detectable 4 to 8 weeks after infection. Shortly thereafter, IgM anti-HBc appears in the blood. HBV DNA testing can potentially detect infection earlier
