Control of the transmission of chikungunya fever epidemic through the use of adulticide

Abstract

Problem statement: Another newly emerging disease, chikungunya fever, has appeared in various places such as the Island of Réunion, Thailand and other India. To control an epidemic of disease once it has been established, the use of adulticide is proposed. Approach: To simulate the effects of different control measurement, a mathematical model incorporating the specific features of this disease has been proposed. Using the standard methods for analyzing the dynamical stability of the system, the role of the efficacy of the adulticide on the basic reproduction number of the disease is studied. Results and Conclusion: It was found that below a particular value of the efficacy which depends on the values of the parameters used in the model, adulticide would not be effective at controlling the epidemic. © 2011 Science Publications.
