Formulation of a vector SIS malaria model in a patchy environment with two age classes.
MetadataShow full item record
We formulate an SIS model describing transmission of highland malaria in Western Kenya, the host population is classified as children, age 1- 5 years and adults, above 5 years. The susceptibility and infectivity of an individual depends on age class and residence. The large scale system with 6n equations is reduced into a compact form of 3n equations by a change of variables. Then 3n equations are vectorialized using matrix theory to get a one dimension, compact form of the system, equation in ]R3n. Using Vidyasagar theorem , the graph of the reduced system is shown to be strongly connected and....................
