Author Information

Hypothesis
To propose a methodology to estimate the number of new HIV infections averted.
Conclusion
The study suggests that a disease modelling-based approach is preferable for estimating HIV infections averted compared to other methods.
Supporting Evidence
- The study discusses three approaches to estimate HIV infections averted: coverage-based, behaviour-based, and disease modelling-based.
- The disease modelling-based approach is preferred as it uses actual data from disease surveillance systems.
- Validation of results using empirical data from different countries is necessary once sufficient data become available.
Takeaway
This study is about figuring out how many new HIV infections we can prevent with different health programs. It shows that using real data from before and after these programs helps us understand their impact better.
Methodology
The study uses cohort-component population projections and disease modelling to compare observed and expected epidemiology of HIV after program initiation.
Potential Biases
The accuracy of data on AIDS cases and deaths has not substantially improved, which may affect the results.
Limitations
Insufficient sentinel surveillance data beyond 2004 hampers the methodology's feasibility.
