"Quarantine" refers to a period during which individuals (people or animals) are kept isolated to prevent the spread of infectious disease.
This term became widely known during health emergencies like the COVID-19 pandemic.
Examples:
- "The dog was kept in quarantine for 10 days after a bite incident."
- "Travelers had to undergo quarantine upon arrival."
Why other options are wrong:
- "Quarter": means a portion or 25%, not related to isolation.
- "Imprisonment": forced confinement as punishment by law.
- "Custody": being kept or detained, but not specifically for disease control.
