Quarantine helps prevent the spread of contagious diseases, such as COVID-19, by restricting close contact between people who are healthy and those who could transmit SARS-CoV-2, the virus that causes the disease.
Anyone who may have come into close contact with SARS-CoV-2 or someone with COVID-19 must quarantine. They will need to remain in quarantine or isolation until they know whether they have contracted the virus or not.
The Centers for Disease Control and Prevention (CDC) define close contact as:
•providing care for someone with COVID-19
•sharing drinking cups or eating utensils with someone with COVID-19
•exposure to droplets from a sneeze, cough, or another source from someone with COVID-19
People with COVID-19 symptoms who can safely recover at home must self-isolate. People who test positive for COVID-19 but have no symptoms also need to self-isolate.
Self-isolation involves staying at home and keeping away from other people. The CDC recommends people take the following steps to self-isolate properly:
•Stay at home except to seek medical care.
•If people need medical care, call a local health authority or hotline first for advice.
•Try to remain in one “sick” room or area and avoid sharing a washroom or kitchen with others, if possible.
•Avoid contact with other household members and pets.
Federal authority for isolation and quarantine comes from the Commerce Clause of the U.S. Constitution.
The U.S. Secretary of Health and Human Services has the authority to prevent the entry and spread of contagious diseases into the U.S. and between states.
The CDC is responsible for carrying out daily actions to limit contagious diseases. The 42 Code of Federal Regulations gives the CDC authority to:
•detain, medically examine, and release persons entering the U.S. or traveling between states who may be carrying a contagious disease
•regularly monitor persons entering U.S. land border crossings and other ports of entry for symptoms and signs of disease
A pilot or captain of a ship can also report passengers or crew members that may be sick to the CDC before they arrive.
Quarantine and isolation both reduce the spread of contagious diseases.
Quarantine restricts the movement of people who have had exposure to a contagious disease to see if they develop the illness.
Isolation separates someone who has contracted a contagious disease from others.
People exposed to someone with COVID-19 or infected respiratory droplets should practice quarantine for 14 days.
