HPVsim: Human Papillomavirus Simulator

Human papillomavirus simulator (HPVsim)

About HPVsim

HPVsim is a flexible agent-based model for simulation HPV transmission and progression through cervical disease to cancer. The model can be parameterized with country-specific vital dynamics, structured sexual networks, co-transmitting HPV genotypes, B- and T-cell mediated immunity, and high-resolution disease natural history. HPVsim is designed with a user-first lens: it is implemented in pure Python, has built-in tools for simulating commonly-used interventions, has been extensively tested and documented, and runs in a matter of seconds to minutes on a laptop.

In mid-2025, version 3.0 of HPVsim will be released, built on the Starsim Starsim modeling architecture. Since this represents a significant shift, version 3.0 and above will live in a separate repository. The code in this repository will be frozen after version 2.2, aside from any critical bugfixes.

Installation

The easiest way to install is simply via pip: pip install hpvsim. Alternatively, you can clone this repository, then run pip install -e . (don't forget the dot!) in this folder to install hpvsim and its dependencies. This will make hpvsim available on the Python path. The first time HPVsim is imported, it will automatically download the required data files (~30 MB). You can also download the data manually by running hpvsim-download-data from the terminal.

Usage and documentation

Documentation is available at https://docs.hpvsim.org. Additional usage examples are available in the tests folder.
