What does ASC mean in medicine?

Asymptomatic carriers of hepatitis B virus ~

Asymptomatic carriers of hepatitis B virus (ASC) are mainly caused by blood contact. They feel that they have no symptoms and signs of hepatitis and all liver function tests are normal. After more than half a year's observation, there is no abnormal change. Because hepatitis B virus will not spread to others through respiratory tract or normal digestive tract, ASC will not cause spread harm to others in daily life and social interaction. They should have the obligation and right to work, study, live and socialize as usual.
