My first thought was some kind of two year life cycle of an organism... there are some strange life cycles out there, like cicadas (or similar) that have 17 year life cycles.
Perhaps this is something similar? Maybe a mosquito-borne parasite with a two year cycle?
- nonbel 7y agoThere really is no need for that. All you need is for the growth in number of susceptible people (usually roughly birthrate) be slow enough that the threshold for an outbreak isn't reached for a couple years. One reason for this could be a previous large outbreak so the growth is starting from a low baseline.
