How robust are estimates of key parameters in standard viral dynamic models?

PLoS Comput Biol

April 2024

Theoretical Biology and Biophysics Group, Theoretical Division, Los Alamos National Laboratory, Los Alamos, New Mexico.

Article Synopsis
  • - Mathematical models for viral infections, such as HIV and hepatitis, are useful for understanding disease progression, but often lack important early data due to the timing of symptom onset and peak viral load.
  • - Missing early viral load data complicates estimating key model parameters like time of infection and cell infection rates, but additional information like time to peak viral load can enhance the accuracy of these estimates.
  • - The study shows that while missing early data can lead to underestimations in time to peak viral load, using known values for certain parameters can still yield reliable estimates for the remaining parameters when early data is not available.
