Enhanced Perinatal Surveillance (EPS)
Purpose: Monitor and reduce perinatal HIV
transmission in Texas.
How is EPS data used?

Determine reasons for prevention failures
Evaluate adverse outcomes from ART use
EPS Data Collection
Instrument Basic demographics for both mother and
child Maternal information
