Effects of migration on vector-borne diseases with forward and backward stage progression. (arXiv:1810.06777v1 [q-bio.PE])
来源于:arXiv
Is it possible to break the host-vector chain of transmission when there is
an influx of infectious hosts into a na\"{i}ve population and competent vector?
To address this question, a class of vector-borne disease models with an
arbitrary number of infectious stages that account for immigration of infective
individuals is formulated. The proposed model accounts for forward and backward
progression, capturing the mitigation and aggravation to and from any stages of
the infection, respectively. The model has a rich dynamic, which depends on the
patterns of infected immigrant influx into the host population and connectivity
of the transfer between infectious classes. We provide conditions under which
the answer of the initial question is positive. 查看全文>>
