Are there some examples of theoretical models that discuss pandemics? I am looking for some papers/references that showcase theoretical economic models that incorporate pandemics. Most work seem to be purely empirical. Does anyone know of some papers that try to model effect of pandemics on economy/economic behavior analytically?

Update:
Some of the theoretical papers that I managed to find with helpful suggestion of kurtosis to include SIR &amp; SEIR in search include:
Daron Acemoglu et al (2020), Optimal Targeted Lockdowns In A Multi-Group SIR Model
Eichenbaum, Martin S., Sergio Rebelo, and Mathias Trabandt. The macroeconomics of epidemics.
Any further suggestions are still welcome
