Age-Structured Core Group Model and Its Impact on STD Dynamics

摘要: The recruitment of new suceptibles into a core group sexually-active individuals may depend on the current levels infection within population. We extend formalism Hadeler and Castillo-Chavez (1995), that includes prevalence dependent rates, to include age structure noncore populations. Some mathematical results are stated but only couple proofs included since our objetives highlight modeling process dynamic possibilities. This paper concludes with an example where endemic distributions can be supported when basic reproductive number R0 is less than one. Systems capable supporting multiple attractors more likely support disease re-emergence. model stable < 1.
