hot zones
High-risk regions
Hot zones are areas of intense danger, activity, or contamination.
The term gained prominence through epidemiology, where it designates regions with active outbreaks of deadly infectious diseases like Ebola.
Military and emergency response contexts use hot zone for combat areas or sites of hazardous material exposure where special protocols apply.
More loosely, any location experiencing concentrated activity or risk might be called a hot zone: The downtown area became a hot zone for protests.
