Notes to Accompany Virginia HIV/AIDS Trends

• All data is reported as of December 31st, 2005
  unless otherwise indicated.
• HIV and AIDS reporting
• Virginia regulations require reporting of HIV and
  AIDS cases separately. As a result, a person can
• be listed as either a Virginia HIV case, a
  Virginia AIDS case, or as both (HIV and AIDS). A
  person
• first diagnosed with HIV infection with no AIDS
  defining events will always be an HIV case. If at
  a
• later time, the patient is diagnosed as AIDS the
  person will be listed as both an HIV and AIDS
• case. If a patient's initial diagnosis of HIV
  infection is accompanied with an AIDS defining
  event,
• the person will be listed as only an AIDS case.
• Unduplicated
• As a result of Virginia reporting regulations for
  HIV and AIDS (see note above), an individual
• could be reported twice, once as an HIV case and
  once as an AIDS case. An unduplicated report
• will count this individual only once. In the case
  of both HIV and AIDS diagnoses for one
  individual,
• age and place of residence at the time of
  diagnosis will derive from the HIV report.
  Unduplicated counts
• will be indicated.
• Living

Notes to Accompany Virginia HIV/AIDS Trends
Geography All location information is based on
the address that is reported to the Division at
the time of report. Report Date vs. Diagnosis
Date Time frames are selected based on either the
date of report or date of diagnosis. The report
date is the date the morbidity is entered into
the database. Diagnosis date is the date the
disease was diagnosed by a health professional.
Statistical reports prepared based on diagnosis
dates are likely to change over time, given that
disease reports sometimes involve time lags of
varying degrees. AIDS Case Definition Change On
January 1, 1993, the AIDS surveillance case
definition for adolescents and adults was
expanded to include three additional clinical
conditions (pulmonary tuberculosis, recurrent
pneumonia, and invasive cervical cancer) as well
as a laboratory marker of severe immunosuppression
in HIV-infected persons
