Scientists build a better math model for how viruses replicate inside cells

Scientists built a new math model to track how viruses grow inside individual cells. This model accounts for the random timing of different replication stages, which older models often ignored.

Old models of viral growth often assumed that each step in a virus's life cycle took a fixed amount of time. This new model shows that the random nature of these steps actually changes how a virus population grows. It gives researchers a more accurate way to understand how infections spread at a very small scale.
