TheOne - 09-25-06 13:03 Explanation: The correct answer is E. Hepatitis B infection can produce a wide variety of clinical outcomes. The most common outcome (60% to 65%), however, turns out to be subclinical disease followed by complete recovery. The other choices listed show other possible outcomes, and their statistical impact is considered with the discussions of individual choices. Approximately 20% to 25% of infected persons develop acute hepatitis (choice A), which is followed in 99% of these cases by recovery and in about 1% of cases by fulminant hepatitis. Approximately 5% to 10% of cases become "healthy" carriers (choice B). Approximately 4% of cases develop persistent infection, 67% to 90% of which then recover (choice C) and 10% to 33% of which have chronic hepatitis (choice D).

babbu5508 - 06-21-10 14:38 E. Subclinical disease followed by recovery because this seems to be the most common outcome of hepatitis b infection in general..
