Public engagement and targeted health education directed at specific sub-populations play a vital role in reducing Ebola virus disease outbreaks. Mathematical analysis using a system of ordinary differential equations examines how behaviour changes induced by education influence transmission dynamics. Historical records from two Ebola outbreaks occurring three years apart in Sudan provide comparative data, as the second outbreak recorded significantly fewer infections after the population learned from the initial event. Parameter estimations derived from these historical cases inform simulations of potential future outbreaks. The model distinguishes between two groups of susceptible individuals, separating those with greater disease awareness from less informed members of the population. The simulated projections demonstrate that maintaining a more educated population substantially lowers total infection numbers, underscoring the critical necessity of sustained public health education campaigns.
Ebola virus disease causes severe outbreaks with high fatality rates. Understanding how community awareness shapes infection spread helps authorities design effective epidemic responses. By quantifying the protective impact of targeted health education, mathematical models show that informing communities proactively is a reliable strategy for reducing case numbers and preventing wide-scale transmission during future outbreaks.
This mathematical model serves as early-stage research that could inform decision-support software for public health agencies and non-governmental organisations planning epidemic interventions. Health authorities might use these computational simulations to guide resource allocation for educational campaigns ahead of future disease threats. However, the abstract indicates no software product or deployment pathway, keeping the work at a theoretical and early simulation stage.

Public involvement in Ebola Virus Disease (EVD) prevention efforts is key to reducing disease outbreaks. Targeted education through practical health information to particular groups and sub-populations is crucial to controlling the disease. In this paper, we study the dynamics of Ebola virus disease in the presence of public health education with the aim of assessing the role of behavior change induced by health education to the dynamics of an outbreak. The power of behavior change is evident in two outbreaks of EVD that took place in Sudan only 3 years apart. The first occurrence was the first documented outbreak of EVD and produced a significant number of infections. The second outbreak produced far fewer cases, presumably because the population in the region learned from the first outbreak. We derive a system of ordinary differential equations to model these two contrasting behaviors. Since the population in Sudan learned from the first outbreak of EVD and changed their behavior prior to the second outbreak, we use data from these two instances of EVD to estimate parameters relevant to two contrasting behaviors. We then simulate a future outbreak of EVD in Sudan using our model that contains two susceptible populations, one being more informed about EVD. Our finding show how a more educated population results in fewer cases of EVD and highlights the importance of ongoing public health education.
