Area of Science:

  • Epidemiology
  • Mathematical Biology
  • Biostatistics

Background:

  • Predicting individual epidemic trajectories requires understanding variability around the mean.
  • The general stochastic epidemic model provides a framework for studying disease spread.

Purpose of the Study:

  • To investigate methods for estimating the variability of epidemic realizations.
  • To extend these methods to complex models of HIV/AIDS transmission.

Main Methods:

  • Utilizing a multivariate normal approximation based on an asymptotic Gaussian diffusion process.
  • Employing an approximating linear stochastic process.

Main Results:

  • Developed approximate estimation methods for epidemic variability.
  • Demonstrated the applicability of these methods to stochastic epidemic models.

Conclusions:

  • The investigated methods provide valuable tools for quantifying epidemic variability.
  • These approaches can be extended to analyze the dynamics of HIV/AIDS transmission.
