Quiz Please

Hepatitis B should be considered a sexually transmitted disease.
 
  • Although Hepatitis B can be spread by blood and blood products, today the main method of dissemination is sexual contact.
  • Ms. JS's unfaithful boyfriend contracted it in one of his escapades.
  • He brought it home.
  • His flu-like illness 4 months back was, in fact, hepatitis.
  • Believe it or not, the majority of people who come down with Hepatitis B don't become jaundiced.
 
  • Ms. JS will recover, but not everyone is so lucky.
  • A small percentage will develop chronic hepatitis, where:
    • the virus persists for years, possibly the life of the person,
    • the continuously mounted T4 lymphocyte response results in destruction of the liver.
  • It becomes an autoimmune injury.
  • People who end up with chronic hepatitis, never develop an antibody to the surface antigen of Hepatitis B.       No surface antibody, no immunity.

So what's important with this case?                                                             Back
