| The mathematical model described by Dye (1996) condemned the epidemiological canine visceral leishma-niasis control campaign, considering it non-efficient. Using this model, we mathematically demonstrate that the control is not efficient, only at low values (rate at which latent and infectious dogs are lost by the destruction program) which match the canine seropositivity observed in the field by the immunofluorescency (IF) blood eluates analysis. With higher k values, corresponding to IF (k = 0.07) or ELISA ( k = 0.25) results in sera samples, the number of infectious dogs declines to a Ro =1 or Ro =0, respectively, interrupting the transmission and the advancement of epidemics. We also experimentally demonstrate that the dog removal, following the... |
