Lockdown has become a common term in the current times where governments around the world are implementing measures to slow the spread of the COVID-19 pandemic. However, there are several synonyms for the word lockdown that can be used. Quarantine refers to isolating people who have been exposed to a contagious disease. Shelter-in-place is another term used to describe staying at home during an emergency like a terrorist attack or natural disaster. Stay-at-home order is another synonym for lockdown that is used by several American states. Self-isolation and curfew are other words that refer to restrictions on movement and gatherings. Whatever the term may be, the goal remains the same - to prevent the spread of the disease.
