REVIEW OF HIV SURVEILLANCE ACTIVITIES IN LATIN AMERICA AND THE CARIBBEAN Surveillance of key affected populations
TXEMA GARCÍA CALLEJA W O R L D H E A LT H O R G A N I Z AT I O N REVIEW PREPARED BY: JERRY O.JACOBSON
OBJECTIVES OF THE REVIEW To assess surveillance systems in LAC by: 1.Identifying types of surveillance activities and kinds of information available to inform understanding of the epidemic 2. Identifying whether plans and sufficient resources are in place for future surveillance in key affected populations
METHODS Data gathered July-Oct, 2012 on 33 countries Desk review: 2010 and 2012 country GARP reports Available materials cited in those reports
Country survey received from 29/33 countries for information unavailable in GARP: PAHO and UNAIDS focal points Surveillance partners, UVG/Tephinet/CDC
Themes based on WHO surveillance evaluation guidelines
THEMES FOR KAP’S 1. The review examined MSM, FSW, DU/IDU and male-tofemale Trans 2. Availability of selected bio-behavioral indicators: •
HIV prevalence & incidence, condom use, HIV testing, exposure to prevention
3. Ability to construct time trends 4. Size estimates 5. Planning and resources for future surveillance rounds
Recent data on MSM available. Except: - VEN, some OECS
Sources of HIV and/or behavioral estimates in KAP's in past 5 years MSM

Mesoamerica
FSW: - Less availability, especially in Andean & Carib. Trans: - Data from MSM subsamples in CA - Trans-specific studies in Andean - No data in Carib. Multiple sources for MSM, FSW, trans available, particularly in Mesoamerica. DU/IDU: Very limited*

ABILITY TO CONSTRUCT TIME TRENDS IN KAP’S
• Tracking trends over time is a principal aim of all surveillance systems.
• The review examined the availability of at least 2 recent “comparable” time points • Typically 3 time points are desired for constructing a trend
HIV prevalence trends (≥ 2 time points)

Greater availability in Mesoamerica and Caribbean for MSM and FSW, largely due to BSS studies (e.g., TRaC).

SIZE ESTIMATES

Few mapping estimates (the method most useful to inform prevention) Range of methods used impedes ability to conduct cross-country comparisons. Many countries must use international estimates to apply estimation/projection models.

PLANNING AND RESOURCES FOR SURVEILLANCE IN KAP’S •
Examined whether plans are currently in place for at least 1 future round of HIV prevalence studies and/or size estimates in MSM and FSW
•
And whether sufficient resources are currently allocated
• The minimum possible measure: does not reflect longterm sustainability
Planning and resources for a future HIV prevalence estimate Most countries do not have plans and sufficient resources in place.
Plans less common for FSW.

KEY FINDINGS: KAP’S Strengths
• Recent bio-behavioral data on MSM throughout LAC • Recent bio-behavioral data on FSW available, with exception of Andean sub-region • Recent studies in trans have revealed a higher risk group. • A small number of studies in DU have documented high prevalences beyond the IDU subgroup. • Time trends for MSM and FSW available in a small number of countries • Size estimates available for MSM and FSW in all sub-regions
KEY FINDINGS: KAP’S Areas for improvement
Limited recent data on FSW in Andean, trans in Caribbean Very limited ability to produce time trends: a need to focus on consistency in methods over time and sustainability. Current situation in DU/IDU largely unknown, no hard data to justify exclusion from surveillance efforts Several countries without size estimates, particularly in DU and trans; limited consistency in methods across countries Regular planning processes and resource allocation for KAP’s a challenge: Sustainability? Impact on ability to construct trends?
