Cost-effectiveness analysis is a mode of determining both the cost and economic health
outcomes of one or more control interventions. In this work, we have formulated a non …

Objectives To map travel policies implemented due to COVID-19 during 2020, and conduct
a mixed-methods systematic review of health effects of such policies, and related contextual …

In this paper, we proposed the optimal control for the dynamics of COVID‐19 with cost
effectiveness strategies. First, we showed that model solution is positive, and bounded in a …

Fractional order and fractal order are mathematical tools that can be used to model real-
world problems. In order to demonstrate the usefulness of these operators, we develop a …

In this article, we have studied the dynamics of the Ebola virus disease by means of
fractional differentiation combined with a fractal dimension. It has been shown explicitly that …

Maize streak virus disease, caused by the maize streak virus, has been identified as severe
vector-borne disease in Africa. In most regions of the continent, the disease is generally …

Typhoid fever is a potentially fatal illness that is caused by the bacteria Salmonella typhi. In
this study, a deterministic mathematical model was formulated to look into transmission …

In late 2019, a novel coronavirus, the SARS-CoV-2 outbreak was identified in Wuhan, China
and later spread to every corner of the globe. Whilst the number of infection-induced deaths …

In this article a deterministic model for Maize Streak Virus Disease (MSVD) using a fractional-
order differential equation with the Atangana-Baleanu Caputo-type operator is developed …

Vaccines are a highly effective intervention in mitigating the COVID-19 pandemic, but with
limited resources, an optimal vaccine allocation plan is essential for reducing the number of …
