Quarantine

Similar to lockdown, quarantine is a period of isolation that prevents the movement of people to slow the spread of the coronavirus (COVID-19). Some areas of northern Italy were placed into quarantine early on in the pandemic in an attempt to contain COVID-19. 

Quarantine is also sometimes used to refer to the period of self-isolation that people must undergo when returning from abroad. If a person returns to the UK from a country that is not on the list of exempt countries, they must self-isolate for 14 days.
