isolation vs quarantine

美风在楼下made a good point about isolation vs quarantine.  Here is some information from CDC:

You quarantine when you might have been exposed to the virus and may or may not have been infected.

 

What to do

•         Stay home for 14 days after your last contact with a person who has COVID-19.
•         Watch for fever (100.4?F), cough, shortness of breath, or other symptoms of COVID-19.
•         If possible, stay away from people you live with, especially people who are at higher risk for getting very sick from COVID-19.

 

You isolate when you have been infected with the virus, even if you don’t have symptoms.

 

What to do

•         Monitor your symptoms. If you have an emergency warning sign (including trouble breathing), seek emergency medical care immediately.
•         Stay in a separate room from other household members, if possible.
•         Use a separate bathroom, if possible.
•         Avoid contact with other members of the household and pets.
•         Don’t share personal household items, like cups, towels, and utensils.
•         Wear a mask when around other people if able.
