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=June 25, 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/>

=== Virus names ===

==== Test positivity rate ====
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” percent positive is 5%, which was used by the WHO in the past.<ref>{{#invoke:Cite web ||date=2020-08-10 |title=COVID-19 Testing: Understanding the "Percent Positive" |url=https://publichealth.jhu.edu/2020/covid-19-testing-understanding-the-percent-positive |access-date=2024-09-26 |website=Johns Hopkins {{!}} Bloomberg School of Public Health |language=en}}</ref>

Many countries attempted to slow or stop the spread of COVID-19 by recommending, mandating or prohibiting behaviour changes, while others relied primarily on providing information.

=== Containment ===
{{further|Zero-COVID}}
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" />

Should containment fail, efforts focus on mitigation: measures taken to slow the spread and limit its effects on the healthcare system and society.
Successful mitigation delays and decreases the epidemic peak, known as "flattening the [[epidemic curve]]".<ref name="Lancet2020Flatten" /> This decreases the risk of overwhelming health services and provides more time for developing vaccines and treatments.<ref name="Lancet2020Flatten" /> Individual behaviour changed in many jurisdictions.

Carnivores were generally less active when humans were around, while herbivores in developed areas were more active.

Similarly, limited digital literacy left the elderly more vulnerable to isolation, depression, and loneliness.<ref>{{#invoke:cite journal || vauthors = Silva MF, Silva DS, Bacurau AG, Francisco PM, Assumpção D, Neri AL, Borim FS | title = Ageism against older adults in the context of the COVID-19 pandemic: an integrative review | journal = Revista de Saúde Pública | volume = 55 | page = 4 | year = 2021 | pmid = 33886953 | pmc = 8023321 | doi = 10.11606/s1518-8787.2021055003082 }}</ref>

In January 2022, [[Amnesty International]] urged [[COVID-19 pandemic in Italy|Italy]] to change their anti-COVID-19 restrictions to avoid discrimination against unvaccinated people, saying that "the government must continue to ensure that the entire population can enjoy its fundamental rights." The restrictions included mandatory vaccination over the age of 50, and mandatory vaccination to use public transport.<ref>{{#invoke:cite news || url=https://www.reuters.com/world/europe/dont-discriminate-against-unvaccinated-amnesty-international-tells-italy-2022-01-16/ | title=Don't discriminate against the unvaccinated, Amnesty International tells Italy | newspaper=Reuters | date=16 January 2022 }}</ref>

A March 2022 review declared a transition to endemic status to be "inevitable".<ref>{{#invoke:Cite journal || vauthors = Koelle K, Martin MA, Antia R, Lopman B, Dean NE |date=11 March 2022 |title=The changing epidemiology of SARS-CoV-2 |journal=Science |volume=375 |issue=6585 |pages=1116–1121 |doi=10.1126/science.abm4915 |issn=1095-9203 |pmc=9009722 |pmid=35271324|bibcode=2022Sci...375.1116K }}</ref> In June 2022, an article in ''[[Human Genome Organisation|Human Genomics]]'' said that the pandemic was still "raging", but that "now is the time to explore the transition from the pandemic to the endemic phase."<ref>{{#invoke:cite journal||doi=10.1186/s40246-022-00392-1|title=COVID-19 2022 update: Transition of the pandemic to the endemic phase|year=2022| vauthors = Biancolella M, Colona VL, Mehrian-Shai R, Watt JL, Luzzatto L, Novelli G, Reichardt JK |journal=Human Genomics|volume=16|issue=1|page=19|pmid=35650595|pmc=9156835|s2cid=249274308 |doi-access=free}}</ref> Another review that month predicted that the virus that causes COVID-19 would become the fifth endemic seasonal coronavirus, alongside four other [[HCoV|human coronavirus]]es.<ref>{{#invoke:cite journal || vauthors = Cohen LE, Spiro DJ, Viboud C |date=30 June 2022 |title=Projecting the SARS-CoV-2 transition from pandemicity to endemicity: Epidemiological and immunological considerations |journal=PLOS Pathogens |volume=18 |issue=6 |pages=e1010591 |doi=10.1371/journal.ppat.1010591 |issn=1553-7374 |pmid=35771775 |pmc=9246171 |doi-access=free }}</ref>

On 5 May 2023, the WHO declared that the pandemic was no longer a [[public health emergency of international concern]].<ref>{{#invoke:cite web||title=WHO declares end to Covid global health emergency|url=https://www.nbcnews.com/health/health-news/who-ends-covid-global-health-emergency-rcna83046|access-date=6 May 2023|website=NBC News|date=5 May 2023}}</ref> This led several media outlets to incorrectly report that this meant the pandemic was "over". The WHO commented to [[Full Fact]] that it was unlikely to declare the pandemic over "in the near future" and mentioned [[cholera]], which it considers to have been a [[seventh cholera pandemic|pandemic since 1961]] (i.e., continuously for the last {{Time ago|1961-05|ago=}}).<ref name="ff">{{#invoke:cite web ||publisher=FullFact.org |date=12 May 2023 |url=https://fullfact.org/health/who-covid-pandemic-over/ | vauthors = Brown F |title=The WHO has not declared the Covid-19 pandemic over}}</ref> The WHO does not have an official category for pandemics or make declarations of when pandemics start or end.<ref name="reuters" /><ref name="guardian" /><ref>{{#invoke:cite news || vauthors = Nebehay S |title=WHO says it no longer uses 'pandemic' category, but virus still emergency |url=https://www.reuters.com/article/uk-china-health-who-idUKKCN20I0PD |access-date=5 August 2023 |work=Reuters |date=24 February 2020 |quote="There is no official category (for a pandemic)," WHO spokesman Tarik Jasarevic said.}}</ref><ref name=timemarch2024/>

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". The WHO in Europe launched a transition plan to manage the public health response to COVID-19 in the coming years and prepare for possible future emergencies.<ref name="kluge">{{#invoke:cite web ||date=12 June 2023 |title=With the international public health emergency ending, WHO/Europe launches its transition plan for COVID-19 |url=https://www.who.int/europe/news/item/12-06-2023-with-the-international-public-health-emergency-ending--who-europe-launches-its-transition-plan-for-covid-19 |publisher=World Health Organization}}</ref>

== 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>

In Australia, the pandemic caused an increase in [[occupational burnout]] in 2022.<ref>{{#invoke:Cite web || vauthors = Churchill B, Bissell D, Ruppanner L |date=19 March 2023 |title=The 'great resignation' didn't happen in Australia, but the 'great burnout' did |url=http://theconversation.com/the-great-resignation-didnt-happen-in-australia-but-the-great-burnout-did-201173 |access-date=30 July 2023 |website=The Conversation }}</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 immunization 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.
