Your brother definitelyhas a type of hepatitis. If Type-B antigen is
negative and also C is negative, did the doctor say he may have Type-A
acute hepstitis ? Sometimes, in the early stages HbsAg will come back negative.
In the acute infection, if these other serological markers are positive, that
makes the diagnosis of Acute B Hepatitis. These are the following-
With the symptom of stomach ache, I would think ,he probably ate
some contaminated food and has developed Acute Hepatitis
level right now is not very high but may go higher before
coming down. If his fever
does not come down and he is not able to
keep anything in the stomach, he might need intravenous fluid support
and hospitalization to follow the enzyme and bilirubin levels. When once
they start to come down, then he can be cared for at home. Type A and
also Type B acute hepatitis, majority will recover completely without
permanent damage to the liver
. Hope you can discuss these with your doctor.
I wish him well.
