Resumen
A SIR-type deterministic mathematical model for three hosts is applied to analyze the transmission process for American tegumentary leishmaniasis in Río Blanco and Las Carmelitas, located in northeastern Salta Province, Argentina, and to derive the expression for the baseline reproducibility number Ro. The model is implemented in the MATLAB environment, and based on data from endemic areas, simulations are performed and numerical estimations of Ro are obtained. Río Blanco shows Ro = 4.689 and Las Carmelitas Ro = 1.948. By studying the model numerically, we also estimate the force of infection, namely 0.239 and 0.171 (unit 1/year), respectively. The simulations show that in Río Blanco, the endemic phase was more sustained than the inter-epidemic phase in Las Carmelitas. The estimations of these epidemiological parameters indicate where the Ministry of Health and Provincial Health Department will experience greater difficulty in controlling and eradicating the disease. 23 11 2663 2671 Marco, J.D., Barroso, P.A., Calvopiña, M., Kumasawa, H., Furuya, M., Korenaga, M., Species assignation of Leishmania from human and canine ATL cases by multilocus enzyme electrophoresis in North Argentina (2005) Am J Trop Med Hyg, 72, pp. 606-611 Salomón, O.D., Sosa-Estani, S., Canini, L., Cordoba, E., Leishmaniasis tegumentaria en un área con niveles epidémicos de transmisión, Salta, Argentina, 1998 (2001) Medicina (B.
