Hepatisis A, B and C
Description
"Hepatitis is an inflammation of the liver. The condition can progress to fibrosis (scarring), cirrhosis or liver cancer.
Hepatitis viruses are the most common cause of hepatitis in the world but other infections, toxic substances (e.g. alcohol, certain drugs), and autoimmune diseases can also cause hepatitis. "
Hepatitis A virus (HAV) is present in the faeces of infected persons and is most often transmitted through consumption of contaminated water or food. Certain sex practices can also spread HAV.
Hepatitis B virus (HBV) is transmitted through exposure to infective blood, semen, and other body fluids.
HBV can be transmitted from infected mothers to infants at the time of birth or from family member to infant in early childhood.
Hepatitis C virus (HCV) is mostly transmitted through exposure to infective blood.
This may happen through transfusions of HCV-contaminated blood and blood products, contaminated injections during medical procedures, and through injection drug use.
Sexual transmission is also possible, but is much less common. There is no vaccine for HCV.
