Viral hepatitis refers
to
inflamma-
tion of
liver
cells.
lt
is
caused
by
at least
seven pathogens, hepatitis A virus
(HAV), hepatitis
B
virus
(HBV), hepati-
tis
C
virus
(HCV), hepatitis
D
virus
(HDV), hepatitis
E
virus
(HEV), hepati-
tis
F
Virus
(HFV)
and
hepatitis G
virus
(HGV),
and
possibly by other unidenti-
fied
viruses.
Laboratory diagnosis
of
viral
hepatitis
is
confirmed
by
the
detection
of
the
relevant
viral antigen(s)
/
antibody
in blood or other body
fluids.
Some-
times
detection
of viral
DNA
or
RNA
may be useful in the diagnosis
and
management of
viral
hepatitis.
Viral
hepatitis causes
liver
damage.
Some
types of chronic
viral
hepatitis,
e.g. hepatitis
B or
C, if
left
unattended, may cause chirrosis
or
even liver cancer in some
patients.
Therefore,
early
detection followed
by
proper treatment and management can
be considered as
the
best approach
to
protect our
health
against viral hepatitis.
