Title: Visualizing the Ebola outbreak in maps and charts

The Ebola virus disease (EVD) outbreak, first identified in 1976 in what is now the Democratic Republic of Congo and South Sudan, has resulted in multiple epidemics with varying scales of impact. Data visualization tools, including maps and charts, are utilized to track the spread, intensity, and geographic distribution of the virus over time.

The World Health Organization (WHO) and other health agencies maintain databases recording confirmed, probable, and suspected cases, as well as fatalities. These datasets are essential for monitoring trends and allocating medical resources. For instance, the 2014–2016 West Africa epidemic was the largest and most complex Ebola outbreak since the virus's discovery, primarily affecting Guinea, Liberia, and Sierra Leone. This outbreak resulted in over 28,000 confirmed cases and approximately 11,000 deaths, according to WHO data.

Subsequent outbreaks have occurred in the Democratic Republic of Congo, Uganda, Gabon, and South Sudan. Visualizations of these events typically highlight specific regions with high incidence rates and track the timeline of case occurrences relative to public health interventions.

Charts often display case fatality rates, which have varied between outbreaks, generally ranging from 25% to 90% depending on the viral strain and the quality of healthcare infrastructure. Maps illustrate the cross-border transmission dynamics, showing how the virus moved between communities and countries.

Current surveillance efforts rely on real-time data feeds to update these visualizations, allowing public health officials to identify emerging hotspots and monitor the effectiveness of containment strategies. The integration of geographic information systems (GIS) with epidemiological data provides a comprehensive view of the disease's progression, aiding in the planning of vaccination campaigns and treatment center placements.
