    • Effects of education, vaccination and treatment on HIV transmission in homosexuals with genetic heterogeneity 

      Kribs, Christopher; Del Valle, Sara; Morales Evangelista, Arlene; Velasco, Maria Cristina; Hsu Schmitz, Shu-Fang (Department of Mathematics, University of Texas at Arlington, 2004)
      Genetic studies report the existence of a mutant allele Δ32 of CC R5 chemokine receptor gene at high allele frequencies ( 10%) in Caucasian populations. The presence of the allele is believed to provide partial or full ...

    • The impact of vaccination and boinfection on HPV and cervical cancer 

      Kribs, Christopher; Crawford, Britnee (American Institute of Mathematical SciencesMathematics Department, University of Texas at Arlington, 2009-09)
      Understanding the relationship between coinfection with multiple strains of human papillomavirus and cervical cancer may play a key role in vaccination strategies for the virus. In this article we formulate a model with ...

    • A simple vaccination model with multiple endemic states 

      Kribs, Christopher; Velasco-Hernandez, Jorge X. (ElsevierDepartment of Mathematics, University of Texas at Arlington, 2000)
      A simple two-dimensional SIS model with vaccination exhibits a backward bifurcation for some parameter values. A two-population version of the model leads to the consideration of vaccination policies in paired border towns. ...

    • Vaccination strategies and backward bifurcation in age-since-infection structured model 

      Kribs, Christopher; Martcheva, Maia (ElsevierDepartment of Mathematics, University of Texas at Arlington, 2002)
      We consider models for a disease with acute and chronic infective stages, and variable infectivity and recovery rates, within the context of a vaccination campaign. Models for SIRS and SIS disease cycles exhibit backward ...
