Instructor's
Note for Hepatitis Case
This
case is actually two separate cases that address viral hepatitis.
This format was selected because many of the clinical, diagnostic
and therapeutic parameters are very similar. The probability that
two members of the same household acquired two separate
forms of viral hepatitis is very small, but it does serve to
illustrate the key medical issues surrounding these prevalent and
infectious liver diseases.

The
Cases
For
the past several months, 22 year old Jon Green had been serving a
church mission in an area close to San Paulo, Brazil when he
began to exhibit several symptoms. Among them were increasing
fatigue, nausea with vomiting, and increasing
jaundice.
Jon also had intermittent periods of fever and chills.
Additionally, he complained of abdominal pain.

8. What are Jon's symptoms?
At
his parents request, the decision was made to send Jon back to
his home near Houston, TX.
In
the meantime, Jon’s sister, 20 year old Laura Green had
visited with relatives in late May near the San Francisco, CA
area where she and some friends attended a musical concert. After
the concert, and on a whim, Laura decided to have her navel
pierced. Although the pierced area was slightly inflamed and sore
for several days, it seemed to heal well and she returned home.
Now, nearly four months later during the last part of September,
Laura, usually active and full of energy, began to feel
increasingly tired and ate very little. As a result, she began to
lose weight and experienced intermittent episodes of vague aching
in the abdominal area.
