Spatial‐temporal basic reproduction number and dynamics for a dengue disease diffusion model

Abstract: A reaction‐diffusion system with free boundary is proposed to describe the transmission of the dengue disease from mosquitoes to humans. In addition to the classical basic reproduction number R0, the spatial‐temporal basic reproduction number R0Ffalse(tfalse) is introduced to determine the persistence and eradication of the disease. Some sufficient conditions for the disease vanishing or spreading are obtained. The disease will go extinct under one of the conditions: the classical basic reproduction number R0… Show more

“…In fact, free boundary value problems have attracted extensive research efforts and remarkable successes have been achieved. They were used to describe spreading phenomena in many fields, such as, wound healing [5], ice melting [22], the transmission of diseases [1,17,32] and species interaction [6,7,15,29,26,28].…”

“…Additionally, many vector-borne disease models with spatial structure employ Eq. (1) as a local description of population dynamics, where the emergence and death rates can take on spatial dependence and X(t) is considered to be a spatially-varying population density [28,29]. Our results will also apply this class of model, provided when controls are allowed to take on spatial dependence and are defined at the local level.…”

“…The long run behavior of system (13) Figure 6 depicts the solutions of model (13) when P = 0 (ie with homogeneity in host's distribution), while Figures 7,8,9,and 10 show the solutions of model (13) in a landscape with heterogeneity in hosts distribution (P > 0). Although mosquito population persists over time, its distribution in the domain is not the same.…”

“…To investigate the spatial heterogeneity effect on the mosquito dynamics, we take the variation of human distribution. Figures 8,9,and 10 show the influence of the spatial heterogeneity of hosts on the dynamics of female mosquitoes. From these figures, one observes that spatial distribution of females in gonotrophic cycle is strongly influenced by the hosts density.…”
