The type of limiting factor involved in the typhoid outbreak that occurred in Ithaca is a density-dependent factor.

Factors that are dependent on population density can have a positive or negative relationship with population size.

Disease, competition, and predation are all density-dependent factors.

These limiting factors, which have a positive relationship with population size, increase with population size and limit growth as population size grows.
