The clinical course of HDV infection depends upon the type of infection:
c____infection with HBV or s__infection in a patient who is already infected with
In coinfection, there is a simultaneous acute H__ infection in conjunction with an
acute H__ infection.
A superinfection of HDV in a hepatitis B chronic carrier produces (little) (severe)
damage. It may cause f____t hepatitis. Many superinfected carriers go on to
develop (acute) (chronic) delta infections.
The identification and classification of the infectious agent for hepatitis NANB is
the focus of intense r____h.
Concerning mode of transmission, hepatitis non-A, non-B is believed to be
capable of both p____l and e___c transmission. However, there is strong
evidence that the (parenteral) (enteric) route is predominant since hepatitis NANB
accounts for 80-90% of all post-t___n hepatitis cases in the U.S. and is a major
source of hepatitis among d___s patients. Proposed nomenclature for blood-
borne hepatitis NANB is hepatitis _ (HCV).
Enteric (epidemic) NANB has been responsible for several large, well-documented
w___borne outbreaks of hepatitis. Most cases have been reported in d__ing
countries or among travelers who have recently returned from areas in which the
disease is known to be e___c. Proposed nomenclature for enteric hepatitis NANB
is hepatitis _ (HEV).
Regarding NANB immunological assays, promising r___h has provided for a
possible immunological assay in the near future. Presently a diagnosis of NANB is
made through c___l symptoms, patient h___y, elevated liver e___s, and the
exclusion of the other types of hepatitis through i_____l assays.
