Hepatitis B “major tri-positive” or “minor tri-positive” is a common folk expression that indicates the body’s response to hepatitis B virus infection. A “major triple-positive” person has three positive indicators, namely HBsAg (+), HBeAg (+) and anti-HBc (+); a “minor triple-positive” person has three other positive indicators, namely HBsAg (+), anti-BeAg (+) and anti-HBc (+). Medically, it is the conversion between HBeAg and anti-HBe. With the fluctuation of the body’s immune function and the replication status of the virus itself, the “major triplet” or “minor triplet” can be cyclically expressed in the same person. So technically speaking whether it’s “big three yang” or “small three yang” is also contagious, the difference is only the strength of the infection.
