A cost-based comparison of quarantine strategies for new emerging diseases
(American Institute of Mathematical Sciences, 2010-07)
A classical epidemiological framework is used to provide a preliminary cost analysis of the effects of quarantine and isolation on the dynamics of infectious diseases for which no treatment or immediate diagnosis tools are ...
An epidemiological approach to the spread of political third parties
(American Insttitue of Mathematical Sciences, 2011-05)
Third political parties are influential in shaping American politics. In this work we study the spread of a third party ideology in a voting population where we assume that party members/activists are more influential in ...
The effect of the HIV/AIDS epidemic on Africa's truck drivers
(American Institute of Mathematical Sciences, 2005-10)
The AIDS epidemic is having a growing impact on the transport
sector of the economy of sub-Saharan Africa, where long-distance truck drivers
are at an increased risk of infection due to their frequent contacts with ...
Sharpness of saturation in harvesting and predation
(American Institute of Mathematical Sciences, 2009-10)
Harvesting and predation occur through contact processes in which the rate at which the managed (prey) population can be found depends on the population size, usually saturating at high densities. Many models incorporate ...
Alternative transmission modes for Trypanosoma cruzi
(American Institute of Mathematical Sciences, 2010-07)
The parasite Trypanosoma cruzi, which causes Chagas’ disease, is
typically transmitted through a cycle in which vectors become infected through
bloodmeals on infected hosts and then infect other hosts through defecation
at ...
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 ...
Modeling nosocomial transmission of rotavirus in pediatric wards
(Springer-Verlag, 2011)
Nosocomial transmission of viral and bacterial infections is a major problem worldwide, affecting millions of patients (and causing hundreds of thousands of deaths) per year. Rotavirus
infections affect most children ...
Am I too fat? Bulimia as an epidemic
(Elsevier, 2003)
For at least the past ten years, eating disorders have had a major impact in the
physical and mental health of women, particularly young women. Anorexia and bulimia
nervosa are closely linked eating disorders. Anorexia ...
