1

hep a caused by blank

picornaviridae

2

hep b caused by blank

hepadnaviridae

3

hep c caused by blank

flaviviridae

4

hep d caused by

not sure

5

most hep has blank genomes

ssRNA

6

only hep virus with dsDNA genome

B

7

only hep viruses that arent sexual and are fecal oral instead

A, E

8

most deadly hepatitis

B then C

9

most chronic hepatitis

C then B

10

hep blank infects like 15 million people but only causes problems in those who already have hep B

D

11

this hep is an acute infection that replicates in intestinal cells

A

12

two phases of hep A infection

pre ecteric, icteric

13

icteric means blank

jaundice

14

fever, lack of energy, anorexia, vomiting phase

pre icteric

15

icteric phase has blank inflammation and necrosis, dark urine, blank is excreted into blood, most patients recover after 1-2 weeks

liver, bilirubin

16

this appears 1-2 months after infection and lasts for a lifetime so wont be infected again

igG

17

this appears at the same time as IgG but is short lived and can be used for diagnosis of recent infection

igM

18

there is a blank for hep A

vaccine

19

infectious hep B particle

dane particle

20

3 forms of surface antigens of hep B

filamentous particles, spherical particles, dane particles

21

onset of hep B is blank compared to A

slow

22

most people blank from hep B

recover

23

two types of hep B

fulminant, chronic

24

fulminant is if hep D is developed with hep B.... blank is very high

mortality

25

hep b vaccine involves blank cells and needs blank doses for being max effective

yeast, 3

26

advantage of blank vaccine is that you cant get sick from it

sick

27

drugs for chronic hep B

alpha interferon, lamivudine, baraclude

28

drugs for chronic hep c

alpha interferon, pegylated alpha interferon, ribavirin + alpha interferon (best treatment)

29

there is no fda approved blank for hep c

vaccine

30

new antivirals for hep c virus are very effective but blank

very expensive

31

hep D is diagnosed by presence of blank

igM antibodies

32

hep e causes blank infection like hep A

acute
