Social distancing
In public health, social distancing, also called physical distancing, is a set of non-pharmaceutical interventions or measures intended to prevent the spread of a contagious disease by maintaining a physical distance between people and reducing the number of times people come into close contact with each other. It usually involves keeping a certain distance from others (the distance specified differs from country to country and can change with time) and avoiding gathering together in larger groups.
By minimising the probability that a given uninfected person will come into physical contact with an infected person, the disease transmission can be suppressed, resulting in fewer deaths. The measures may be used in combination with other public health recommendations, such as good respiratory hygiene, use of face masks when necessary, and hand washing. To slow down the spread of infectious diseases and avoid overburdening healthcare systems, particularly during a pandemic, several social-distancing measures have been used, including the closing of schools and workplaces, isolation, quarantine, restricting the movement of people and the cancellation of mass gatherings. Drawbacks of social distancing can include loneliness, reduced productivity and the loss of other benefits associated with human interaction.
Social distancing measures are most effective when the infectious disease spreads via one or more of the following methods: droplet contact (coughing or sneezing), direct physical contact (including sexual contact), indirect physical contact (such as by touching a contaminated surface), and airborne transmission (if the microorganism can survive in the air for long periods). The measures are less effective when an infection is transmitted primarily via contaminated water or food or by vectors such as mosquitoes or other insects. Authorities have encouraged or mandated social distancing during the COVID-19 pandemic as it is an important method of preventing transmission of COVID-19.[citation needed] COVID-19 is much more likely to spread over short distances than long ones. COVID-19 can spread over distances longer than 2 m (6 ft) in enclosed, poorly ventilated places and with prolonged exposure.
The term "social distancing" was not introduced until 2003. Social distancing measures have been successfully implemented in several epidemics. In St. Louis, shortly after the first cases of influenza were detected in the city during the 1918 flu pandemic, authorities implemented school closures, bans on public gatherings and other social-distancing interventions. The influenza fatality rates in St. Louis were much less than in Philadelphia, which had fewer cases of influenza but allowed a mass parade to continue and did not introduce social distancing until more than two weeks after its first cases.
The World Health Organization (WHO) has suggested using the term "physical distancing" instead of "social distancing" because it is physical separation which prevents transmission; people can remain socially connected by meeting outdoors at a safe distance (when there is no stay-at-home order) and by meeting via technology.
The American Centers for Disease Control and Prevention (CDC) have described social distancing as a set of "methods for reducing frequency and closeness of contact between people in order to decrease the risk of transmission of disease". During the 2009 swine flu pandemic the WHO described social distancing as "keeping at least an arm's length distance from others, [and] minimizing gatherings". During the COVID-19 pandemic, the CDC defined social distancing as "remaining out of congregate settings, avoiding mass gatherings, and maintaining distance (approximately six feet or two meters) from others when possible".
Social distancing, combined with the use of face masks, good respiratory hygiene and hand washing, is considered the most feasible way to reduce or delay a pandemic.
Several social distancing measures are used to control the spread of contagious illnesses. Research indicates that measures must be applied rigorously and immediately in order to be effective.
