Is Viral Hepatitis Contagious?
Transmission of Viral Hepatitis from Person to Person
Viral Hepatitis is considered to be contagious between people.
Generally the infectious agent may be transmitted by saliva, air, cough, fecal-oral route,
surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc.
Viral Hepatitis, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
The contagious disease, Viral Hepatitis, can be transmitted:
- by sexual conduct between people.
- from person to person by blood.
- from the mother to her fetus.
- from person to person by saliva, air, coughing, contact, surfaces, fecal-oral route, etc.
Discussion about Contagion of Viral Hepatitis:
There are four different types of infectious hepatitis viruses, but
only three of them can spread to uninfected people: they are HBV, HCV, and
HDV and can be spread in the following ways (Delta hepatitis, spread by
HDV, is spread only when HBV is present through the same ways listed
below):
-
Having sexual intercourse with an infected person without
using a condom.
-
Sharing drug needles among users of injected street
drugs.
-
Needle-stick accidents among health-care workers.
-
Mother-to-child transmission of HBV during birth.
-
Transfusions. Until recently, blood transfusions were the
most frequent cause of hepatitis C. Blood banks in the United States now
screen donated blood for HBV and HCV and discard any blood that appears
to be infected. Therefore, the risk of acquiring hepatitis from these
viruses is very low in the U.S. and in other countries where blood is
similarly tested. Tests to screen blood for HBV will also screen out
HDV.
-
Personal contact with an infected person. HBV, HCV, and
HDV sometimes spread when household members unknowingly come in contact
with virus-infected blood or body fluids--most probably through cuts and
scrapes or by sharing personal items such as razors and toothbrushes.
While it is possible to become infected by contact with saliva, blood
and semen remain the major sources of infection.

About contagion and contagiousness:
Contagion and contagiousness refers to how easily
the spread of Viral Hepatitis is possible from one person to another.
Other words for contagion include "infection", "infectiousness",
"transmission" or "transmissability".
Contagiousness has nothing to do with genetics
or inheriting diseases from parents.
