Hepatitis B – serum hepatitis

Hepatitis B (also called serum hepatitis) is caused by the hepatitis B virus (HBV). HBV can cause a wide spectrum of symptoms ranging from general malaise to chronic liver disease that can lead to liver cancer.

The hepatitis B virus spreads through:

Hepatitis B infected body fluids, such as blood, saliva, semen, vaginal fluids, tears, and urine
a contaminated blood transfusion (uncommon in the United States)
shared contaminated needles or syringes for injecting drugs
sexual activity with an HBV-infected person
transmission from HBV-infected mothers to their newborn babies
