A stay-at-home order (North America) or a movement control order (Southeast Asia) is an order from a government authority to restrict movements of a population as a mass quarantine strategy for suppressing, or mitigating, an epidemic, or pandemic, by ordering residents to stay home except for essential tasks or to work in essential businesses. In many cases, outdoor activities are allowed. Nonessential businesses are either closed or adapted to working from home. In some regions, it has been implemented as a round-the-clock curfew or called a shelter-in-place order, but it is not to be confused with a shelter in place situation. Similar measures have been used around the world, but the term lockdown is used instead. Some officials have a concern that the word lockdown may send a wrong message for people to incorrectly think that it includes door-to-door searching for infected people to be forced into quarantines similar to the Hubei lockdown.
