Abstract
Due to the fact that the dynamic medical material distribution is vital to the quick response to urgent demand when the Ebola virus occurs, the optimal distribution approach is explored according to the Ebola virus diffusion rule and different severity of the epidemic. First, we choose the more serious epidemic state of Sierra Leone in West Africa as the research object and the SIQR (susceptible, infected, quarantined, required) epidemic model with pulse vaccination is introduced to describe the Ebola diffusion rule and obtain the demanded vaccine and drug in each pulse. Based on the SIQR model, thirteen areas in Sierra Leone are classified into three emergency levels by clustering analysis. Then a dynamic medical material distribution model is formulated, with goals of both reducing the transportation cost and shortages. The results indicate that the proposed approach can make an outstanding contribution to fight against the Ebola virus.
Highlights
The deadly hemorrhagic fever Ebola was firstly discovered in 1976, and it has haunted in people’s mind for twenty years
According to the Ebola virus spreading rules and different severity of epidemic, how to distribute drugs reasonably in the affected areas with the limited resources and effectively fight against the Ebola virus will be the focus of this paper
We choose Sierra Leone in West Africa where the Ebola virus most seriously spreads as an example—7 distribution stations to deliver vaccine or drug to around 13 areas
Summary
The deadly hemorrhagic fever Ebola was firstly discovered in 1976, and it has haunted in people’s mind for twenty years. SHS Web of Conferences two aspects: how to describe the spread characteristics of the Ebola virus to predict the required number of vaccines or drugs? Due to the completely different severity of the epidemic, the outbreak of the Ebola virus in the West African countries and the emergency degrees of each epidemic are not the same. The severity of the epidemic should be taken into consideration as important factors on the distribution of materials. According to the Ebola virus spreading rules and different severity of epidemic, how to distribute drugs reasonably in the affected areas with the limited resources and effectively fight against the Ebola virus will be the focus of this paper
