About Lockdown in brief

Summary LockdownA lockdown is a requirement for people to stay where they are, usually due to specific risks to themselves or to others if they can move freely. Lockdowns can also be used to protect people inside a facility or, for example, a computing system, from a threat or other external event. Lockdown procedures vary by site and country. By early April 2020, 3.9 billion people worldwide were under some form of lockdown—more than half the world’s population. Nearly 300 million people, or about 90 per cent of the population, were under lockdown in the United States, and 1.3 billion people in India. In prisons, the term can be defined as a lockdown to control the movement of inmates. Confining all prisoners, except workers, to their cells until the end of the day is an example of a lockdown. In the U.S., the term lockdown is used when all prisoners are locked in their cells to prevent prison riots from spreading or during an emergency.

The term is also used for a prison protocol that usually prevents people, information or objects from leaving an area. In buildings doors leading outside are usually locked so that no person may enter or exit. In some locations, windows are covered, and students stand at the back of the classroom or away from windows. Some schools direct teachers to continue standard procedures while some recommend an active approach against threats. In US guidelines, preventing entry into a hospital may include preventing power failure, earthquake, flooding, fire, and active shooter. Occasions for both external and internal disturbance may include: contamination, civil disturbance and abduction of a child.
