Epidemiological Models For Mutating Pathogens With Temporary Immunity
… we develop an SIR model with variable infection age for the transmission of a pathogen that can mutate in the host to produce a second infectious mutant strain. We assume that there is a period of temporary immunity in the model. A temporary immunity period along with variable infection …

Study of Behaviour Change and Impact on Infectious Disease Dynamics by Mathematical Models
… present a novel perspective on understanding the infection force, incorporating human protection behaviours. This view explains many existing infection force functions and motivates new forms of infection force functions. We demonstrate an SIRS model with time delay, considering disease …

Molecular detection and factors associated with selected tickbone zoonoses in dogs in Chilanga district in Zambia
… of vector-borne zoonoses. Among some of these infections are pathogens transmitted by ticks which are currently considered to be second only to mosquitoes as vectors of human infectious diseases in the world. Tick-borne zoonoses are not considered a priority due to resource constraints and …

Structured deterministic models applied to malaria and other endemic diseases
… Some of the compartments have a continuous age-structure, which is necessary for studying the specific biological questions under investigation.^ In Chapter 2 a chronological-age structured deterministic model for malaria is presented. The model includes the human and mosquito populations …

Human Immunodeficiency Virus/Human Papillomavirus co-infection and host molecular genetics of cervical carcinoma
… of the number of absolute CD4 count. During infection, viral peptides are recognized by the host immune system. It is reasonable to propose that the development of viral-associated cancers, like cervical cancer, requires interference with specific immune-response genes. This thesis …
