New antiviral drugs offer hope for treating HIV and hepatitis B virus infections. Mathematical models help understand viral dynamics, immune response, drug resistance, and potential cures.

Area of Science:

  • Virology
  • Mathematical Biology
  • Immunology

Background:

  • Potent antiviral drugs have been developed for human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infections.
  • These drugs provide quantitative insights into in vivo viral dynamics.
  • Mathematical models are crucial for interpreting experimental data on virus-host interactions.

Purpose of the Study:

  • To discuss the current understanding of virus population dynamics.
  • To explore the role of the immune system in controlling viral load.
  • To examine the emergence and dynamics of viral drug resistance.
  • To address the possibility of eliminating viral infections through drug treatment.

Main Methods:

  • Utilizing mathematical models to describe nonlinear interactions between virus and host cell populations.
