hepadnavirus
what is the virus in hep C
flavivirus
what is the virus in hep E
calicivirus
what is the virus in hep G
flavivirus
which heps result in no chronic infection
A and E
which heps can be prevented by immunisation
A,B,D
what is the mode of transmission for hep A
fecal oral
what is the mode of transmission for hep E
fecal oral
what can cause hep A
feces. water and raw food, travel
incubation time of hep B
45-180 days (6 months)
transmission hep B
sexual, parenteral, perinatal
antigen markers hep B
HBs- Ag, HBe-Ag, anti HBs, anti HBc, anti HBc IgM, anti HBe
what does HBs-AG indicate
early, active infection
what does HBe-AG indicate
replication marker, bad prognosis
what indicator would rise when vaccinated
anti-HBs
lab diagnostics of Hep B
PCR, serology
how does Hep D exist
only alongside hep B- satellite virus
what does HBV and HDV together mean
severe acute hep,decreased risk of chronic.
what is the transmission of hep C
IV drugs, unclear, sexual
which is more likely to develop into hepatocellular carcinoma from Hep C and B
Hep C
incubation time for hep c
2-26 weeks (6 months)
what is hep G associated with
not liver disease, benign, replicates in lymphocytes
what is the presentation of hep A
fever, malaise, anorexia, nausea, arthralgia, jaundice
what is the presentation of hepB
similar to hep A but arthralgia and urticarial commoner
