public health risk
Threat to populations
A public health risk is a condition, behavior, or agent that threatens the health of a population rather than just individuals.
Contaminated water supplies, infectious disease outbreaks, and environmental toxins qualify as public health risks.
The term often appears in official declarations that trigger government intervention: Officials declared the outbreak a public health risk.
Something labeled a public health risk warrants collective action—quarantines, recalls, or policy changes.
