Optimal control analysis of Ebola disease with control strategies of quarantine and vaccination

Metrics details. Ebola virus disease EVD is a severe infection with an extremely high fatality rate spread through direct and indirect contacts. We study the spread of EVD through a two-patch model. We determine the basic reproduction number, the disease-free equilibrium, two boundary equilibria and the endemic equilibrium when the disease persists in the two sub-populations for specific conditions. Further, we introduce time-dependent controls into our proposed model.

Dynamical analysis and control strategies in modelling Ebola virus disease

Amira Rachah, Delfim F. The Ebola virus is currently one of the most virulent pathogens for humans. The latest major outbreak occurred in Guinea, Sierra Leone, and Liberia in With the aim of understanding the spread of infection in the affected countries, it is crucial to modelize the virus and simulate it. In this paper, we begin by studying a simple mathematical model that describes the Ebola outbreak in Liberia. Then, we use numerical simulations and available data provided by the World Health Organization to validate the obtained mathematical model. Moreover, we develop a new mathematical model including vaccination of individuals.

Zotero Mendeley EndNote. By using mathematical modeling and analysis, thelatest major outbreak of Ebola virus in West Africa is described. Our aim is tostudy and discuss the properties of SEIR models with respect to Ebola virus,the information they provide, and when the models make sense. Numerical simulations con…rm the theoretical analysis. The control of the propagation of the virus through vaccination is investigatedand the case study of Liberia is discussed in detail.

Dynamical Models of Tuberculosis and Their Applications

Metrics details. The Ebola epidemic is the largest in history, affecting multiple countries in West Africa. Some isolated cases were also observed in other regions of the world. In this paper, we introduce a deterministic SEIR type model with additional hospitalization, quarantine and vaccination components in order to understand the disease dynamics. Optimal control strategies, both in the case of hospitalization with and without quarantine and vaccination are used to predict the possible future outcome in terms of resource utilization for disease control and the effectiveness of vaccination on sick populations.

In this paper, a non-linear mathematical model for the dynamics of Ebola virus diseases is formulated and analysed. The model has five classes namely susceptible human, exposed human, infected human, treated human and recovered human. Invariant region and positivity solution of the model are determined.

Ebola virus is very challenging problem of the world. The main purpose of this work is to study fractional Ebola virus model. An efficient computational method based on iterative scheme is proposed to solve fractional Ebola model numerically. Stability of proposed method is also discussed. Efficiency of proposed method is shown by listing CPU time. Proposed computational method will work for long time domain. Numerical results are presented graphically.

Она поймала себя на мысли, что глаза ее смотрят в пустоту. Прижавшись лицом к стеклу, Мидж вдруг почувствовала страх - безотчетный, как в раннем детстве. За окном не было ничего, кроме беспросветного мрака. Шифровалка исчезла. ГЛАВА 57 В туалетных комнатах шифровалки не было окон, и Сьюзан Флетчер оказалась в полной темноте.

На крыше главного служебного здания АНБ вырос лес из более чем пятисот антенн, среди которых были две большие антенны, закрытые обтекателями, похожими на громадные мячи для гольфа. Само здание также было гигантских размеров - его площадь составляла более двух миллионов квадратных футов, вдвое больше площади штаб-квартиры ЦРУ. Внутри было протянуто восемь миллионов футов телефонного кабеля, общая площадь постоянно закрытых окон составляла восемьдесят тысяч квадратных футов. Сьюзан рассказала Дэвиду про КОМИ НТ, подразделение глобальной разведки, в распоряжении которого находилось немыслимое количество постов прослушивания, спутников-шпионов и подслушивающих устройств по всему земному шару. Ежедневно тысячи сообщений и разговоров перехватывались и посылались экспертам АНБ для дешифровки. Разведданные, поставляемые агентством, влияли на процесс принятия решений ФБР, ЦРУ, а также внешнеполитическими советниками правительства США. Беккер был потрясен.

 - Он откашлялся.  - Он нацелен на фильтры безопасности. Фонтейн побледнел. Он, конечно, понял, чем это грозит: червь сожрет фильтры, содержащие информацию в тайне, и без них она станет доступна всем без исключения.

Мысли его перенеслись назад, в детство. Родители… Сьюзан. О Боже… Сьюзан.

 Не знаете, как его зовут. Клушар на мгновение задумался и покачал головой: - Понятия не имею.  - Он поморщился от боли и откинулся на подушки.
