Thoughts

what’s unspecified and / or inconsistent:

once in a million (of what?) patients (all? dead?) or simulations?
change state != only one rule can be applied. diabetes
monster rule is applied even after another rule

a few ways of handling deadly rule first:

manual ordering
apply all rules. easiest to extend, computationally most expensive
runtime fail fast (as a result expect not state but wrapper that throws exception when gets DEAD state)
static: remove dead from state enum. none programmer will ever make a mistake but requires a bit more complex architecture

possible DSL

Healthy.with(Insulin, Antibiotic).becomes(Fever)
when(Healthy).gets(Insulin, Antibiotic).becomes(Fever)
when(Diabetes).gets(Insulin).becomes(Diabetes).otherwise(Dead)

possible improvements

debugging. each rule could have a label / description so that it’s easier to trace which rule kicked in
