| Response from Dr. Rodriguez-Torres
The major viral hepatitis are A,B, and C.HAV is trasmitted by the oral fecal route.The virus is present in the feces of infected patients and can infect others tha ingest food or water that is contaminated with fecal material.It is more prevalent in less developed countries.There is a very effective vaccine available. HCV is a blood borne disease that is trasmitted by contact with blood only.Sexual trasmission is possible but is not frequent. It is very frequent in IV drug users,blood recipients before 1992.There is no vaccine. HBV is also a blood borne virus but also is very effectively transmitted by sexual contact.There is a vaccine that is very effective and mandatory since childhood in the U.S.
