Analysis of yellow fever prevention strategy from the perspective of mathematical model and cost-effectiveness analysis

Abstract: <abstract><p>We developed a new mathematical model for yellow fever under three types of intervention strategies: vaccination, hospitalization, and fumigation. Additionally, the side effects of the yellow fever vaccine were also considered in our model. To analyze the best intervention strategies, we constructed our model as an optimal control model. The stability of the equilibrium points and basic reproduction number of the model are presented. Our model indicates that when yellow fever becomes e… Show more

“…To conduct further analysis on the qualitative behaviour of our model, it is important to determine the related basic reproduction number of our proposed model. In many epidemiological models, basic reproduction number holds an important role in determining that the diseases die out or exist in the population [34][35][36][37][38]. Basic reproduction number is defined as the expected number of secondary cases caused by one primary case during infection period in a completely susceptible population [39,40].…”

“…In many epidemiological models, the basic reproduction number determines the existence or disappearance of the disease. In several epidemiological models [26][27][28][29][30], the disease has a chance to die out from the population if the basic reproduction number is less than one and always exists if the basic reproduction number is larger than one. Using the next-generation method [31], the basic reproduction number of System (1) will be calculated as follows.…”

“…Mathematical models have been used widely by researchers to understand how vector-borne diseases spread among the population [19][20][21][22][23]. For the dengue transmission model, many authors have used mathematical modeling to guide public health strategies to control the spread of dengue.…”
