Second-generation HIV surveillance other than providing core
basic serosurveillance activities also collects and integrates data reported
from various sources, such as behavioural and sexually transmitted infection
(STI) surveillance, HIV/AIDS case reporting and death registration.
Second-generation HIV surveillance helps provide a better
understanding of trends over time and of behaviours driving the epidemic in a
country. It helps focus on subpopulations that are at highest risk for
infection and has the flexibility to change with the state of the epidemic.
Second-generation
surveillance in the WHO South-East Asia Region
All
countries in the WHO South-East Asia Region have established
second-generation HIV surveillance systems and several countries now have HIV
serosurveillance and behavioural data collected over a period of time. Data
on the size of high-risk populations, HIV prevalence among the youth, HIV
prevalence among TB patients, utilization of surveillance data for programme
planning and monitoring, as well as capacity to use available software for
producing reliable HIV estimates are proposed to be generated.
The WHO Regional Office for South-East Asia is focusing on
the following activities for countries in the Region.
1. Systematic
evaluation of the surveillance system
2. Documentation
of epidemiologic information
3. Estimation
of people living with HIV/AIDS and projections
Coordination with other agencies for providing coordinated technical
assistance.
