Effects of education, vaccination and treatment on HIV transmission in homosexuals with genetic heterogeneity
(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 ...
A simple vaccination model with multiple endemic states
(Elsevier, 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. ...
Vector consumption and contact process saturation in sylvatic transmission of T. cruzi
(Taylor & Francis, 2006)
Recent research in the transmission of the protozoan parasite Trypanosoma cruzi,
some strains of which cause Chagas’ disease, suggests that consumption of vectors
by sylvatic hosts such as raccoons may play a role in ...
Vaccination strategies and backward bifurcation in age-since-infection structured model
(Elsevier, 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 ...
