This study introduces a conditional likelihood method to estimate human immunodeficiency virus (HIV) infections using acquired immunodeficiency syndrome (AIDS) incidence data. The approach provides reliable estimates and projections for HIV/AIDS epidemic trends.

Area of Science:

  • Epidemiology
  • Biostatistics
  • Public Health

Background:

  • Accurate estimation of human immunodeficiency virus (HIV) infections is crucial for understanding the acquired immunodeficiency syndrome (AIDS) epidemic.
  • Traditional back-calculation methods provide estimates but can be refined for improved statistical rigor.

Purpose of the Study:

  • To develop and evaluate a conditional likelihood approach for estimating HIV incidence from AIDS incidence data.
  • To project future AIDS incidence based on these improved HIV infection estimates.
  • To assess the statistical properties and computational advantages of the proposed method.

Main Methods:

  • Employed a conditional likelihood framework for estimating HIV infections and epidemic parameters.
  • Utilized asymptotic theory to establish the properties of the estimators.

  • Computed standard deviations for HIV incidence estimates and projected AIDS incidence using multinomial distributions.

    • Main Results:

    • The conditional likelihood method is asymptotically equivalent to standard likelihood approaches.
    • The method facilitates the computation of confidence intervals for HIV incidence estimates.
    • Demonstrated the application of the methods using real-world AIDS data from the United States.

    Conclusions:

    • The conditional likelihood approach offers a statistically sound and computationally feasible method for HIV/AIDS epidemiological analysis.
    • This method enhances the accuracy of HIV infection estimation and AIDS incidence projection.
    • The findings support the use of this technique for informing public health strategies.
