Ebola

This term refers specifically to the disease caused by the virus, though in common usage, it is often used interchangeably with the name of the virus itself. Because it describes a specific medical condition, it is treated as an uncountable noun.

In a clinical or journalistic context, the word carries a heavy connotation of urgency, danger, and crisis. It is typically paired with terms related to containment, outbreaks, and public health emergencies rather than general illness.
