Neural posterior estimation (NPE) provides a simulation-based inference method for outbreak characteristics.
NPE can analyze data without manual selection of summary measurements.
Estimates from NPE closely matched those from established Bayesian methods.
The method allows for rapid generation of estimates after initial training.
Results depend on the accuracy of input data and underlying disease models.

Unreliable estimates may occur if observed data differ significantly from training simulations.

Not applicable; the method does not diagnose individual infections.

The framework is not a replacement for diagnostic testing or epidemiological investigation.

Careful evaluation of model selection and neural network design is essential.
Multiple phylogenetic trees should be used to account for uncertainty in reconstruction.
