According to HHS, to Isolation and quarantine, are public health practices used to protect the public by preventing exposure to people who have or may have a contagious disease.
Isolation separates sick people with a contagious disease from people who are not sick.

Officially, the definition of “quarantine” is very specific: It’s the seclusion of a person potentially exposed to a disease for a period of time to see if they become infected. A person under quarantine typically stays in one place to avoid nearly all contact with the outside world. When such quarantine is ordered by the government, it’s illegal to violate them: Breaking a federal quarantine is punishable by a fine or imprisonment, according to the Centers for Disease Control and Prevention. An individual found violating a federal quarantine order could face a fine of up to $100,000, a year in jail, or both, according to a report from the Congressional Research Service.
Many states also have their own punishments for violating quarantine, though they vary widely.
