00:01 Viral hepatitis. 00:02 We’ll go through the important causes of viral hepatitis or hepatites. 00:08 In general, self-limited acute – A, acute, give yourself an example – viral hepatitis A. 00:17 E, we’ll talk about in a little bit. 00:19 And then we'll talk about viruses that usually affect the liver in an acute nature – EBV, CMV, HSV. 00:28 Chronic hepatitis, more so dealing with your B, C and D. 00:39 Begin by looking at our hepatitis A. 00:42 Acute, A. 00:44 Transmission: feco-oral transmission. 00:47 Incubation period, about two to six weeks. 00:50 Presents with nausea and vomiting – n/v. 00:54 And think about where your liver is, RUQ, right upper quadrant pain, with jaundice. 00:59 Remember that jaundice, mixed picture. 01:01 All depends as to how much damage has taken place to liver. 01:04 What kind of clues are they going to give you on your board, so that you know as to – wow, liver might be affected?

IV drug abusers or IV drug users. 01:55 Homosexuals, remember feco-oral is your route. 02:00 Patients with chronic liver disease. 02:02 And the reason for that, remember, A will not cause chronicity. 02:06 However, if there's a pre-existing liver disease, then hepatitis A will only make it worse and allow the patient to go into fulminant hepatitis. 02:16 Vaccinate, close contact of a case in which maybe perhaps there is something with close encounters that might have taken place. 02:26 For example, think about prisoners and convicts. 02:29 Immunoglobulin useful for passive immunity for suspected exposure if used within two weeks. 02:36 Prevention becomes important here with hepatitis A. 02:39 This is where your focus should be, approximately two weeks.
