![عکس صفحه اول مقاله: The role of sexually abstained groups in two-sex demographic and epidemic logistic models with non-linear mortality The role of sexually abstained groups in two-sex demographic and epidemic logistic models with non-linear mortality](/preview/png/4497995.png)
We describe several gender structured population models governed by logistic growth with non-linear death rate. We extend these models to include groups of people isolated from sexual activity and individuals exposed to a mild and long-lasting sexually transmitted disease, i.e. without disease-induced mortality and recovery. The transmission of the disease is modeled through formation/separation of heterosexual couples assuming that one infected individual automatically infects his/her partner. We are interested in how the non-reproductive class may change the demographic tendencies in the general population and whether they can curb the growth of the infected group while keeping the healthy one at acceptable levels. A comparison of the equilibrium total population size in the presence and the absence of the isolated class is also provided.
