| Summary: | In this paper, a deterministic model for the transmission dynamics of measles infection with two doses of vaccination and isolation is studied. The disease-free equilibrium state and basic reproduction number,, of the model are computed. The sensitivity analysis of the model parameters is carried out using the Latin Hypercube Sampling (LHS) scheme in other to ascertain the crucial parameters that contribute to the spread of measles in the population. The result of the sensitivity analysis shown that transmission rates, vaccination rates and isolation of the infected persons in prodromal stage are significant parameters to be targeted for the eradication of measles infection. Based on the result of sensitivity analysis, the optimal control analysis is carried out using Pontryagin’s maximum principle to identify the optimal control strategies to be adopted by public health practitioners and policy health makers in curtailing the spread of measles infection. The result of the numerical simulations revealed that combined implementation of timely and correct administration of the two doses of vaccination, isolation of infected persons in prodromal stage and mass distribution of nutritional support will curtail the measles disease outbreak in the population. However, in a situation where there is limited facility to isolated the infected persons in prodromal stage, the combined implementation of mass distribution of nutritional support and administration of the two doses of vaccination will still eradicate measles infection in the population. |
