The '''COVID-19 pandemic''' (also known as the '''coronavirus pandemic''' and '''COVID pandemic'''), caused by severe acute respiratory syndrome coronavirus 2 ([[SARS-CoV-2]]), began with an [[disease outbreak|outbreak]] of [[COVID-19]] in [[Wuhan]], China, in December 2019. It spread to other areas of Asia, and [[COVID-19 pandemic by country and territory|then worldwide]] in early 2020. The [[World Health Organization]] (WHO) declared the outbreak a [[public health emergency of international concern]] (PHEIC) on 30 January 2020, and assessed the outbreak as having become a [[pandemic]] on 11 March.<ref name=start/>

[[COVID-19 symptoms]] range from [[asymptomatic]] to deadly, but most commonly include fever, [[sore throat]], [[nocturnal cough]], and fatigue. [[Transmission of COVID-19|Transmission of the virus]] is often [[airborne transmission|through airborne particle]]s. Mutations have [[variants of SARS-CoV-2|produced many strain]]s (variants) with varying degrees of infectivity and [[virulence]].<ref>{{#invoke:cite web ||title=Clinical questions about COVID-19: Questions and answers |url=https://stacks.cdc.gov/view/cdc/89817 |website=CDC Stacks |date=25 June 2020 |access-date=26 May 2023}}</ref> [[COVID-19 vaccine]]s were developed rapidly and [[deployment of COVID-19 vaccines|deployed]] to the general public beginning in December 2020, made available through government and [[International organization|international]] programs such as [[COVAX]], aiming to provide [[vaccine equity]]. [[Treatment and management of COVID-19|Treatment]]s include [[COVID-19 drug development|novel antiviral drug]]s and symptom control. Common mitigation measures during the public health emergency included [[travel restrictions related to the COVID-19 pandemic|travel restriction]]s, [[COVID-19 lockdowns|lockdown]]s, business restrictions and closures, [[workplace hazard controls for COVID-19|workplace hazard control]]s, [[face masks during the COVID-19 pandemic|mask mandate]]s, quarantines, [[COVID-19 testing|testing]] systems, and [[contact tracing]] of the infected.

The pandemic caused severe [[social impact of the COVID-19 pandemic|social]] and [[economic impact of the COVID-19 pandemic|economic disruption]] around the world, including [[COVID-19 recession|the largest global recession]] since the [[Great Depression]].<ref name="RFXoH">{{#invoke:cite web || url=https://blogs.imf.org/2020/04/14/the-great-lockdown-worst-economic-downturn-since-the-great-depression/ | vauthors  = Gita G |title=The Great Lockdown: Worst Economic Downturn Since the Great Depression|website=IMF Blog|date=14 April 2020 |access-date=23 April 2020}}</ref> [[Shortages related to the COVID-19 pandemic|Widespread supply shortage]]s, including [[food security during the COVID-19 pandemic|food shortage]]s, were caused by [[2021–2022 global supply chain crisis|supply chain disruption]]s and [[panic buying]]. Reduced human activity led to an [[impact of the COVID-19 pandemic on the environment|unprecedented temporary decrease in pollution]]. [[Impact of the COVID-19 pandemic on education|Educational institution]]s and public areas were partially or fully closed in many jurisdictions, and many events were cancelled or postponed during 2020 and 2021. [[Remote work|Telework]] became much more common for [[white-collar worker]]s as the pandemic evolved. [[COVID-19 misinformation|Misinformation circulated]] through [[impact of the COVID-19 pandemic on social media|social media]] and [[media coverage of the COVID-19 pandemic|mass media]], and [[political impact of the COVID-19 pandemic|political tensions intensified]]. The pandemic raised issues of [[xenophobia and racism related to the COVID-19 pandemic|racial and geographic discrimination]], [[health equity]], and the balance between [[public health]] imperatives and [[individual and group rights|individual rights]].

The WHO ended the PHEIC for COVID-19 on 5 May 2023.<ref name=reuters/> The disease has continued to circulate, but as of 2024, experts were uncertain as to whether it was still a pandemic.<ref name=timemarch2024/><ref>{{#invoke:cite news ||last1=Colarossi |first1=Jessica |title=Is COVID-19 Still a Pandemic? |url=https://www.bu.edu/articles/2024/is-covid-19-still-a-pandemic/ |access-date=9 June 2024 |work=The Brink |publisher=Boston University |date=5 March 2024 |language=en |archive-date=15 May 2024 |archive-url=https://web.archive.org/web/20240515084249/https://www.bu.edu/articles/2024/is-covid-19-still-a-pandemic/ |url-status=live }}</ref> Pandemics and their ends are not well-defined, and whether or not one has ended differs according to the definition used.<ref name=timemarch2024/><ref name=charters2021/> As of {{COVID-19 data/Date|format=j F Y}}, COVID-19 has caused {{COVID-19 data/Text|XW|deaths}} confirmed deaths.

=== Pandemic ===
In [[epidemiology]], a [[pandemic]] is defined as "an epidemic occurring over a very wide area, crossing international boundaries, and usually affecting a large number of people". During the COVID-19 pandemic, as with other pandemics, the meaning of this term has been challenged.<ref>{{#invoke:cite journal ||vauthors=Doraiswamy S, Mamtani R, Cheema S |title=An in-depth analysis of 10 epidemiological terminologies used in the context of COVID-19 |journal=Scand J Public Health |volume=50 |issue=6 |pages=819–826 |date=August 2022 |pmid=34903120 |pmc=9361413 |doi=10.1177/14034948211057736 |url=}}</ref>

The end of a pandemic or other epidemic only rarely involves the total disappearance of a disease, and historically, much less attention has been given to defining the ends of epidemics than their beginnings. The ends of particular epidemics have been defined in a variety of ways, differing according to academic field, and differently based on location and social group. An epidemic's end can be considered a social phenomenon, not just a biological one.<ref name=charters2021/>

[[Time (magazine)|''Time'']] reported in March 2024 that expert opinions differ on whether or not COVID-19 is considered endemic or pandemic, and that the WHO continued to call the disease a pandemic on its website.<ref name=timemarch2024/>

One measure that public health officials and policymakers have used to monitor the pandemic and guide decision-making is the test positivity rate ("percent positive"). According to Johns Hopkins in 2020, one benchmark for a "too high" per cent positive is 5%, which was used by the WHO in the past.<ref>{{#invoke:Cite web ||date=10 August 2020 |title=COVID-19 Testing: Understanding the "Percent Positive" |url=https://publichealth.jhu.edu/2020/covid-19-testing-understanding-the-percent-positive |access-date=26 September 2024 |website=Johns Hopkins {{!}} Bloomberg School of Public Health |language=en}}</ref>

=== Containment ===

Containment is undertaken to stop an outbreak from spreading into the general population. Infected individuals are isolated while they are infectious. The people they have interacted with are contacted and isolated for long enough to ensure that they are either not infected or no longer contagious. Screening is the starting point for containment. Screening is done by checking for symptoms to identify infected individuals, who can then be isolated or offered treatment.<ref name="f4SpW">{{#invoke:cite news||title=Fever Screening|url=https://intellisec.co.za/fever-screening/|website=IntelliSEC &#124; Durban, Johannesburg, Cape Town}}</ref> The zero-COVID strategy involves using public health measures such as [[contact tracing]], [[COVID-19 testing|mass testing]], [[travel during the COVID-19 pandemic|border quarantine]], [[COVID-19 lockdowns|lockdown]]s, and [[use and development of software for COVID-19 pandemic mitigation|mitigation software]] to stop [[transmission of COVID-19|community transmission]] of COVID-19 as soon as it is detected, with the goal of getting the area back to zero detected infections and resuming normal economic and social activities.<ref name=Barcelona /><ref name="Lancet-Li-2020">{{#invoke:cite journal || vauthors = Li Z, Chen Q, Feng L, Rodewald L, Xia Y, Yu H, Zhang R, An Z, Yin W, Chen W, Qin Y, Peng Z, Zhang T, Ni D, Cui J, Wang Q, Yang X, Zhang M, Ren X, Wu D, Sun X, Li Y, Zhou L, Qi X, Song T, Gao GF, Feng Z | title = Active case finding with case management: the key to tackling the COVID-19 pandemic | journal = Lancet | volume = 396 | issue = 10243 | pages = 63–70 | date = July 2020 | pmid = 32505220 | pmc = 7272157 | doi = 10.1016/S0140-6736(20)31278-2 }}</ref> Successful containment or suppression reduces [[basic reproduction number#Effective reproduction number|Rt]] to less than 1.<ref name="ImpCollege16mar2020" />

[[File:04.02 總統視察「中央流行疫情指揮中心」 49726568957 66543b616e o.jpg|thumb|The CDC and WHO advise that masks (such as worn here by Taiwanese President [[Tsai Ing-wen]]) reduce the spread of SARS-CoV-2.]]
[[Non-pharmaceutical intervention]]s that may reduce spread include personal actions such as wearing [[face masks during the COVID-19 pandemic|face mask]]s, self-quarantine, and [[hand washing|hand hygiene]]; community measures aimed at reducing interpersonal contacts such as closing workplaces and schools and cancelling large gatherings; community engagement to encourage acceptance and participation in such interventions; as well as environmental measures such as surface cleaning.<ref name="community mitigation" />

==== Other measures ====
More drastic actions, such as quarantining entire populations and strict travel bans have been attempted in various jurisdictions.<ref name="RwmYm" /> The [[Chinese government response to COVID-19|Chinese]] and [[COVID-19 pandemic in Australia#Responses|Australian government approach]]es have included many lockdowns and are widely considered the most strict. The [[New Zealand government response to the COVID-19 pandemic|New Zealand government response]] included the most severe travel restrictions. As part of its [[K-Quarantine]] program, South Korea introduced mass screening and localised quarantines, and issued alerts on the movements of infected individuals. The [[COVID-19 pandemic in Singapore#Government response|Singaporean government's response]] included so-called "[[2020 Singapore circuit breaker measures|circuit breaker lockdown]]s" and financial support for those affected while also imposing large fines for those who broke quarantine.<ref name="shZdf" />

==== Contact tracing ====
{{See also|Use and development of software for COVID-19 pandemic mitigation|Public health mitigation of COVID-19#Information technology}}
[[Contact tracing]] attempts to identify recent contacts of newly infected individuals, and to screen them for infection; the traditional approach is to request a list of contacts from infectees, and then telephone or visit the contacts.<ref name="web" /> Contact tracing was widely used during the [[Western African Ebola virus epidemic]] in 2014.<ref>{{#invoke:cite journal || vauthors = Webb G, Browne C, Huo X, Seydi O, Seydi M, Magal P |title=A model of the 2014 ebola epidemic in west Africa with contact tracing |journal=PLOS Currents |date=30 January 2015 |volume=7 |pages=ecurrents.outbreaks.846b2a31ef37018b7d1126a9c8adf22a | doi = 10.1371/currents.outbreaks.846b2a31ef37018b7d1126a9c8adf22a | doi-broken-date = 1 November 2024 | doi-access = free |url=https://currents.plos.org/outbreaks/article/a-model-of-the-2014-ebola-epidemic-in-west-africa-with-contact-tracing-2/ |pmid=25685636 |pmc=4323422 |issn=2157-3999}}</ref>

In November 2023, in response to viral mutations and changing characteristics of infection, the WHO adjusted its treatment guidelines.

In 2020, a worldwide study on mammalian wildlife responses to human presence during COVID lockdowns found complex patterns of animal behaviour. Carnivores were generally less active when humans were around, while herbivores in developed areas were more active.

[[Ageism|Age-based discrimination]] against older adults increased during the pandemic.

In June 2023, [[Hans Kluge]], director of the WHO in Europe, commented that "While the international public health emergency may have ended, the pandemic certainly has not".

== Long-term effects ==
=== Economic ===
Despite strong economic rebounds following the initial lockdowns in early 2020, towards the latter phases of the pandemic, many countries began to experience long-term economic effects. Several countries saw high [[inflation rate]]s which had global impacts, particularly in developing countries.<ref>{{#invoke:Cite web ||date=16 May 2023 |title=Post-pandemic world economy still feeling COVID-19's sting |url=https://news.un.org/en/story/2023/05/1136727 |access-date=30 July 2023 |website=UN News }}</ref> Some economic impacts such as [[supply chain]] and trade operations were seen as more permanent as the pandemic exposed major weaknesses in these systems.<ref>{{#invoke:Cite news ||date=23 June 2023 |title=Not Everything Is Getting Back to Normal In the Post-Pandemic Economy |work=Bloomberg.com |url=https://www.bloomberg.com/news/articles/2023-06-23/podcast-not-everything-is-getting-back-to-normal-in-the-post-pandemic-economy |access-date=30 July 2023}}</ref>

During the pandemic, a large percentage of workers in Canada came to prefer working from home, which had an impact on the traditional work model. Some corporations made efforts to force workers to return to work on-site, while some embraced the idea.<ref>{{#invoke:Cite web || vauthors = Granja AD, Champagne E, Choinière O |date=27 April 2023 |title=Post-pandemic work in the public sector: A new way forward or a return to the past? |url=http://theconversation.com/post-pandemic-work-in-the-public-sector-a-new-way-forward-or-a-return-to-the-past-204008 |access-date=30 July 2023 |website=The Conversation }}</ref>

=== Travel ===
There was a "travel boom" causing air travel to recover at rates faster than anticipated, and the aviation industry became profitable in 2023 for the first time since 2019, before the pandemic.<ref>{{#invoke:Cite web ||date=5 June 2023 |title=IATA says airline industry is rapidly returning to profitability |url=https://www.euronews.com/2023/06/05/iata-says-air-passenger-numbers-have-almost-recovered-to-pre-covid-19-levels |access-date=30 July 2023 |website=euronews }}</ref> However, economic issues meant some predicted that the boom would begin to slow down.<ref>{{#invoke:Cite web || vauthors = Sutherland B |date=28 July 2023 |title=Post-pandemic travel boom is running out of steam |url=https://www.japantimes.co.jp/commentary/2023/07/28/world/covid-travel-boom/ |access-date=30 July 2023 |website=The Japan Times }}</ref> Business travel on airlines was still below pre-pandemic levels and is predicted not to recover.<ref>{{#invoke:Cite news || vauthors = Sugiura E, Wright R |date=7 July 2023 |title=Can the post-pandemic travel boom endure? |work=Financial Times |url=https://www.ft.com/content/f9cb24f5-8da8-4956-966b-a1348b79e151 |access-date=30 July 2023}}</ref>

=== Health ===
An increase in excess deaths from underlying causes not related to COVID-19 has been largely blamed on systematic issues causing delays in health care and screening during the pandemic, which has resulted in an increase of non-COVID-19 related deaths.<ref>{{#invoke:Cite web ||title='Excess' Deaths Surging, but Why? |url=https://www.medscape.com/viewarticle/989530 |access-date=30 July 2023 |website=Medscape }}</ref>

=== Immunizations ===
During the pandemic, millions of children missed out on vaccinations as countries focused efforts on combating COVID-19. Efforts were made to increase vaccination rates among children in [[low-income countries]]. These efforts were successful in increasing vaccination rates for some diseases, though the UN noted that post-pandemic [[measles vaccination]]s were still falling behind.<ref>{{#invoke:Cite web ||date=17 July 2023 |title=Global immunisation rates show sign of post-pandemic rebound |url=https://news.un.org/en/story/2023/07/1138767 |access-date=30 July 2023 |website=UN News }}</ref>

Some of the decrease in immunisation was driven by an increase in mistrust of public health officials. This was seen in both low-income and high-income countries. Several [[African countries]] saw a decline in vaccinations due to misinformation around the pandemic flowing into other areas.<ref>{{#invoke:Cite web ||title=COVID pandemic created immunisation gaps in Africa.
