D. Persistent infection progressing to chronic hepatitis
i guess that as HBV infection can be transmitted by one drop of infected blood

E. Subclinical disease followed by recovery
HBV is more easily transmitted than HIV by needle stick injury but usually causes subclinical disease with recovery.

Theoritically, the health worker would be infected although according to CDC based retrospective research chance of infection is 0.42% (ref : www.Uptodate.com).
So once infected.....either B or D could be the consequence of the HBV.

hey guys ...its ..
.E. Subclinical disease followed by recovery
and explanation given is
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)
