Transmission category definitions

• Multiple imputation was used to re-distribute transmission category where missing

• MSM = Male to male sexual contact• IDU = Injection drug use• MSM/IDU = Male to male sexual contact and injection drug

use• HET = Heterosexual contact with a person known to have, or

to be at high risk for, HIV infection• Other = hemophilia, blood transfusion, perinatal exposure,

and risk factor not reported or not identified

The HIV Care Continuum can help us…

• Focus our efforts for linkage, retention and viral suppression.• Identify groups at increased risk for dropping out of each

step in the continuum.• Monitor our progress in improvement of linkage, retention,

and viral suppression.• Identify disparities not only in prevalence but in care• Evaluate efforts addressing specific populations with low

viral suppression.• Monitor efforts in improving viral suppression in specific

counties, census tracts, zip codes and some specific facilities• Encourage improvement in surveillance data completeness

(race, sex, transmission category)

Stage of HIV disease at diagnosis

• Stage at diagnosis is defined by the first CD4 done within 3 months of diagnosis

Stage 1 = CD4 >=500Stage 2 = CD4 200-499Stage 3 = CD4 <200 or OI

• Stage at diagnosis is unknown if no CD4 done within 3 months of diagnosis

Limitations

• Incomplete reporting • Missing data for race/ethnicity, sex, and complete

address at diagnosis• Lack of transmission category information• Estimation using multiple imputation to

redistribute risk when missing• Definition of heterosexual transmission (sexual

contact with a known HIV infected partner or person with increased risk, i.e., MSM or IDU)

• Missing laboratory reports• CD4 within 3 and 12 months of diagnosis yields

high unknown stage in Georgia

Uncertainties

• Populations for which data are missing may be fundamentally different

• How to obtain data for transgender category• How to improve completeness of reporting• Data on ART use• Understanding barriers to ART adherence• Prioritizing further research
