Stochastic dynamics of dengue epidemics.
We use a stochastic Markovian dynamics approach to describe the spreading of vector-transmitted diseases, such as dengue, and the threshold of the disease. The coexistence space is composed of two structures representing the human and mosquito populations. The human population follows a susceptible-infected-recovered (SIR) type dynamics and the mosquito population follows a susceptible-infected...
متن کاملDynamics of Dengue epidemics using optimal control
We present an application of optimal control theory to Dengue epidemics. This epidemiologic disease is an important theme in tropical countries due to the growing number of infected individuals. The dynamic model is described by a set of nonlinear ordinary differential equations, that depend on the dynamic of the Dengue mosquito, the number of infected individuals, and the people’s motivation t...
متن کاملSpatiotemporal Dynamics of Dengue Epidemics, Southern Vietnam
An improved understanding of heterogeneities in dengue virus transmission might provide insights into biological and ecologic drivers and facilitate predictions of the magnitude, timing, and location of future dengue epidemics. To investigate dengue dynamics in urban Ho Chi Minh City and neighboring rural provinces in Vietnam, we analyzed a 10-year monthly time series of dengue surveillance dat...
متن کاملModelling the dynamics of dengue real epidemics.
In this work, we use a mathematical model for dengue transmission with the aim of analysing and comparing two dengue epidemics that occurred in Salvador, Brazil, in 1995-1996 and 2002. Using real data, we obtain the force of infection, Λ, and the basic reproductive number, R(0), for both epidemics. We also obtain the time evolution of the effective reproduction number, R(t), which results in a ...
متن کامل[Cultural conceptions on dengue in urban contexts in Mexico].
OBJECTIVE To explore the conceptual dimensions of dengue in the urban context, aiming at creating hypotheses about community attitudes toward prevention campaigns. METHODS An exploratory cross-sectional study was carried out between March and April 2003 comprising 130 people selected by proposition sampling in three municipalities with different dengue prevalences in Mexico. Semi-structured i...
