Disease vectors are well understood from the theoretical point of view, but rely on variables that can only be explained by sociological and anthropological notions that are not only extremely difficult to quantify, but also that can change dynamically as societies react in response to pandemics. Physical models may be extremely complex but physical constants do not change unpredictably over time.
