What Happens When You Are Quarantined? Governments use quarantines to stop the spread of contagious diseases. Quarantines are for people or groups who don’t have symptoms but were exposed to the sickness. A quarantine keeps them away from others so they don’t unknowingly infect anyone. Quarantines may be used during:
Outbreaks: When there’s a sudden rise in the number of cases of a disease.
Epidemics: Similar to outbreaks, but generally considered larger and more widespread.
Pandemics: Larger than epidemics, generally global in nature and affect more people.
