{{cs1 config|name-list-style=vanc}}
Pandemic prevention is the organization and management of preventive measures against pandemics. Those include measures to reduce causes of new infectious diseases and measures to prevent outbreaks and epidemics from becoming pandemics. It is not to be mistaken for pandemic preparedness or mitigation (e.g. against COVID-19) which largely seek to mitigate the magnitude of negative effects of pandemics, although the topics may overlap with pandemic prevention in some respects.
Pandemics typically arise naturally from interactions between humans and animals,{{Cite web |date=2019-05-07 |title=6 in 10 Infectious Diseases Come from Animals.

Pandemic prevention measures include early detection systems, international coordination with information sharing, laboratory biosafety protocols, oversight of gain-of-function research, restricting access to dual-use biotechnology, monitoring spillover risks in wild animal populations, regulating wildlife trade and wet markets, reducing intensive animal farming, protecting ecosystems, and strengthening public health care systems.

= 2002–2004 SARS outbreak =
During the 2002–2004 SARS outbreak, the SARS-CoV-1 virus was prevented from causing a pandemic of Severe acute respiratory syndrome (SARS). Rapid action by national and international health authorities such as the World Health Organization helped to slow transmission and eventually broke the chain of transmission, which ended the localized epidemics before they could become a pandemic. Human-to-human transmission of SARS may be considered eradicated, however, it could re-emerge as SARS-CoV-1 probably persists as a potential zoonotic threat in its original animal reservoir.{{cite journal | vauthors = Morens DM, Fauci AS | title = Emerging Pandemic Diseases: How We Got to COVID-19 | journal = Cell | volume = 182 | issue = 5 | pages = 1077–1092 | date = September 2020 | pmid = 32846157 | pmc = 7428724 | doi = 10.1016/j.cell.2020.08.021 }} This warrants monitoring and reporting of suspicious cases of atypical pneumonia.{{Cite web|url=https://www.who.int/mediacentre/news/releases/2003/pr56/en/|archive-url=https://web.archive.org/web/20040825184057/http://www.who.int/mediacentre/news/releases/2003/pr56/en/|archive-date=August 25, 2004|title=WHO | SARS outbreak contained worldwide|website=WHO|date=}} Effective isolation of patients was enough to control spread because infected individuals usually do not transmit the virus until several days after symptoms begin and are most infectious only after developing severe symptoms.{{cite web |title=SARS: How a global epidemic was stopped |url=https://iris.wpro.who.int/bitstream/handle/10665.1/5530/9290612134_eng.pdf |access-date=25 March 2020|date=}} Nevertheless several studies warned about the possible pandemic threat posed by coronaviruses.{{Cite journal |last1=Mahroum |first1=Naim |last2=Seida |first2=Imen |last3=Esirgün |first3=Serhat N. |last4=Bragazzi |first4=Nicolò L. |title=The COVID-19 pandemic - How many times were we warned before? |journal=European Journal of Internal Medicine |date=November 2022 |volume=105 |pages=8–14 |doi=10.1016/j.ejim.2022.07.009 |pmid=35864073 |pmc=9289047 |url=https://doi.org/10.1016/j.ejim.2022.07.009}}{{Cite book |last1=Turinici |first1=Gabriel |last2=Danchin |first2=Antoine |chapter=The SARS Case Study: An Alarm Clock? |editor-last=Tibayrenc |editor-first=Michel |editor-link=Michel Tibayrenc |title=Encyclopedia of Infectious Diseases |date=2007 |pages=151–162 |publisher=Wiley |doi=10.1002/9780470114209.ch9|isbn=978-0-471-65732-3 |url=https://hal.archives-ouvertes.fr/hal-00536581/file/sars_encyclopedia_turinici_danchin2007.pdf }}

In January 2022, Chinese scientists at the Wuhan University and other institutions reported in a preprint the detection of the closest MERS-CoV relative in bats to date, NeoCoV, and another virus, PDF-2180-CoV, that can efficiently use bats' ACE2 for cell entry. The study, now published in Nature found that one mutation could result in a theoretical 'MERS-CoV-2' that, like SARS-CoV-2, can use humans' ACE2 receptor. The theoretical virus could also have a high mortality burden, since MERS-CoV had a case fatality rate of around 35%.{{cite web |title=Middle East respiratory syndrome coronavirus (MERS-CoV) |url=https://www.who.int/news-room/fact-sheets/detail/middle-east-respiratory-syndrome-coronavirus-(mers-cov) |website=www.who.int |access-date=18 February 2022 |language=en}} This 'MERS-CoV-2' therefore represents a risk to biosafety and potential zoonotic spillover.{{cite journal | vauthors = Xiong Q, Cao L, Ma C, Tortorici MA, Liu C, Si J, Liu P, Gu M, Walls AC, Wang C, Shi L, Tong F, Huang M, Li J, Zhao C, Shen C, Chen Y, Zhao H, Lan K, Corti D, Veesler D, Wang X, Yan H | display-authors = 6 | title = Close relatives of MERS-CoV in bats use ACE2 as their functional receptors | journal = Nature | volume = 612 | issue = 7941 | pages = 748–757 | date = December 2022 | pmid = 36477529 | pmc = 9734910 | doi = 10.1038/s41586-022-05513-3 | doi-access = free | bibcode = 2022Natur.612..748X }}{{cite news |title=Scientists evaluate zoonotic potential of NeoCoV, a coronavirus related to MERS-CoV |url=https://www.news-medical.net/news/20220130/Scientists-evaluate-zoonotic-potential-of-NeoCoV-a-coronavirus-related-to-MERS-CoV.aspx |access-date=12 February 2022 |work=News-Medical.net |date=30 January 2022 |language=en}} The study emphasized the need for pathogen/spillover surveillance to further understand any possible threat from related viruses.{{cite news |title=Fact Check-NeoCov is not a new type of human transmissible coronavirus |url=https://www.reuters.com/article/factcheck-neocov-virus-idUSL1N2UC2MH |work=Reuters |date=1 February 2022 |language=en}} The WHO stated that further study is needed to find out "whether the virus detected in the study will pose a risk for humans".{{cite news |title=NeoCov's potential danger to humans requires further study — WHO |url=https://tass.com/society/1394163 |access-date=12 February 2022 |work=TASS}}{{additional citation needed|date=February 2023}}

Potential policies that support global biosafety could make use of various technologies, including but not limited to laboratory containment technologies – for example, tools could promote compliance with existing and novel biosecurity norms and standards. Proposals to increase biosafety in terms of laboratories, scientific field work and research and development-related activities include:
- limiting research on highly contagious biological agents to only trained researchers in well-protected environments and advanced biological safety systems and disposal of biohazards.

=== Risks of pandemic prevention ===
Efforts of pandemic prevention and related endeavors carry risks of triggering pandemics themselves. These risk include unwitting laboratory escape and accidents such as spillovers during field interventions like wildlife virus sampling,{{cite news | vauthors = Lerner S |title=The Virus Hunters: How the Pursuit of Unknown Viruses Risks Triggering the Next Pandemic |url=https://theintercept.com/2021/12/28/covid-pandemic-virus-hunters-ecohealth-alliance-peter-daszak-wuhan/ |access-date=12 February 2022 |work=The Intercept |date=28 December 2021}}{{cite journal | vauthors = Ali Al Shehri S, Al-Sulaiman AM, Azmi S, Alshehri SS | title = Bio-safety and bio-security: A major global concern for ongoing COVID-19 pandemic | journal = Saudi Journal of Biological Sciences | volume = 29 | issue = 1 | pages = 132–139 | date = January 2022 | pmid = 34483699 | pmc = 8404373 | doi = 10.1016/j.sjbs.2021.08.060 | bibcode = 2022SJBS...29..132A }} and misuse of its results due to e.g. insecure commercial sales of required equipment and/or materials and/or data. However, not engaging in any form of sampling also carries risks, as it could leave communities unprepared for future spillover events and unaware of future potential pathogens.{{cn|date=January 2025}}
One approach to mitigate risks from pandemic prevention is to "maintain a database with hashes of deadly and dangerous sequences" which don't contain data with a potential for danger (depending on various factors) and also "can't be reverse-engineered to learn the dangerous original sequence if you don't already know it". This would theoretically enable checking sequences against a database of recorded pathogens without maintaining a database of deadly sequences. Another approach is not building such databases or not collecting dangerous sequences in the first place. A 2014 study proposed safer "alternatives to experiments with novel potential pandemic pathogens" than some of the current methods.{{cite journal | vauthors = Lipsitch M, Galvani AP | title = Ethical alternatives to experiments with novel potential pandemic pathogens | journal = PLOS Medicine | volume = 11 | issue = 5 | pages = e1001646 | date = May 2014 | pmid = 24844931 | pmc = 4028196 | doi = 10.1371/journal.pmed.1001646 | doi-access = free }}

In a 2012 study it is claimed that "new mathematical modelling, diagnostic, communications, and informatics technologies can identify and report hitherto unknown microbes in other species, and thus new risk assessment approaches are needed to identify microbes most likely to cause human disease". The study investigates challenges in moving the global pandemic strategy from response to pre-emption.{{cite journal | vauthors = Morse SS, Mazet JA, Woolhouse M, Parrish CR, Carroll D, Karesh WB, Zambrana-Torrelio C, Lipkin WI, Daszak P | display-authors = 6 | title = Prediction and prevention of the next pandemic zoonosis | journal = Lancet | volume = 380 | issue = 9857 | pages = 1956–1965 | date = December 2012 | pmid = 23200504 | pmc = 3712877 | doi = 10.1016/S0140-6736(12)61684-5 }} Some scientists are screening blood samples from wildlife for new viruses.{{cite magazine | vauthors = Walsh B |title=Virus Hunter: How One Scientist Is Preventing the Next Pandemic |url=https://time.com/3782263/virus-hunter-how-one-scientist-is-preventing-the-next-pandemic |magazine=Time |access-date=26 March 2020 |language=en-us}} The international Global Virome Project (GVP) aims to identify the causes of fatal new diseases before emergence in human hosts by genetically characterizing viruses found in wild animals.{{cite web | vauthors = McKie R |title=Scientists aim to stop the devastation of Zika-like pandemics |url=https://www.theguardian.com/science/2018/jun/24/global-pandemic-prevented-map-animal-virus-ebola-sars-zika |website=The Observer |access-date=3 April 2020 |date=24 June 2018}} The project aims to enlist an international network of scientists to collect hundreds of thousands of viruses, map their genomes, characterize and risk-stratify them to identify which ones to pay attention to.

In March 2020 scientists of Stanford University presented a CRISPR-based system, called PAC-MAN (Prophylactic Antiviral Crispr in huMAN cells), that can find and destroy viruses in vitro. However, they weren't able to test PAC-MAN on the actual SARS-CoV-2, use a targeting-mechanism that uses only a very limited RNA-region, haven't developed a system to deliver it into human cells and would need a lot of time until another version of it or a potential successor system might pass clinical trials. In the study published as a preprint they write that it could be used prophylactically as well as therapeutically. The CRISPR-Cas13d-based system could be agnostic to which virus it's fighting so novel viruses would only require a small change.{{cite magazine | vauthors = Levy S |title=Could Crispr Be Humanity's Next Virus Killer? |url=https://www.wired.com/story/could-crispr-be-the-next-virus-killer/ |magazine=Wired |access-date=25 March 2020 |language=en}}{{cite bioRxiv | vauthors = Abbott TR, Dhamdhere G, Liu Y, Lin X, Goudy L, Zeng L, Chemparathy A, Chmura S, Heaton NS, Debs R, Pande T, Endy D, La Russa M, Lewis DB, Qi LS | display-authors = 6 |title=Development of CRISPR as a prophylactic strategy to combat novel coronavirus and influenza |date=14 March 2020 |biorxiv=10.1101/2020.03.13.991307}} In an editorial published in February 2020 another group of scientists claimed that they have implemented a flexible and efficient approach for targeting RNA with CRISPR-Cas13d which they have put under review and propose that the system can be used to also target SARS-CoV-2 in specific.{{cite journal | vauthors = Nguyen TM, Zhang Y, Pandolfi PP | title = Virus against virus: a potential treatment for 2019-nCov (SARS-CoV-2) and other RNA viruses | journal = Cell Research | volume = 30 | issue = 3 | pages = 189–190 | date = March 2020 | pmid = 32071427 | pmc = 7054296 | doi = 10.1038/s41422-020-0290-0 }} There have also been earlier successful efforts in fighting viruses with CRISPR-based technology in human cells.{{cite web | vauthors = Lewis T |title=Scientists Program CRISPR to Fight Viruses in Human Cells |url=https://www.scientificamerican.com/article/scientists-program-crispr-to-fight-viruses-in-human-cells/ |website=Scientific American |access-date=1 April 2020 |language=en |date=23 October 2019}}{{cite web |title=Combatting Viruses with RNA-Targeted CRISPR |url=https://www.the-scientist.com/daily-news/combatting-viruses-with-rna-targeted-crispr-35580 |website=The Scientist Magazine® |access-date=1 April 2020 |language=en}} In March 2020 researchers reported that they have developed a new kind of CRISPR-Cas13d screening platform for effective guide RNA design to target RNA.

===Syndromic surveillance and border control===
Expert on infectious diseases at the Johns Hopkins Center for Health Security, Amesh Adalja states that the most immediate way to predict a pandemic is with deeper surveillance of symptoms that fit the virus' profile. The scientific and technological ways of quickly detecting a spillover could be improved so that an outbreak can be isolated before it becomes an epidemic or pandemic. David Quammen states that he heard about the idea to develop technology to screen people at airport security points for whether or not they carry an infectious disease ten years ago and thought it was going to be done by now. Thermometers whose measurement data is directly shared via the Internet and medical guidance apps have been used to plot and map unusual fever levels to detect anomalous outbreaks.{{cite news | vauthors = Sharma S |title=We need an early-warning system to prevent pandemics like Covid-19: Inder Singh |url=https://economictimes.indiatimes.com/opinion/interviews/we-need-an-early-warning-system-to-prevent-pandemics-like-covid-19-inder-singh/articleshow/75687552.cms |website=The Economic Times |access-date=12 August 2021}} Various forms of data-sharing could be added to health care institutions such as hospitals so that e.g. anonymized data about symptoms and incidences found to be unusual or characteristic of a pandemic threat could enable high-resolution "syndromic surveillance" as an early warning system.

In December 2020 during the COVID-19 pandemic, national and international officials reported mutated variants of SARS-CoV-2, including some with higher transmissibility and worldwide spread. While mutations are common for viruses and the spread of some of the virus' mutations have been tracked earlier, mutations that make it more transmittable or severe can be problematic. Resources for disease surveillance have improved during the pandemic so that medical systems around the world are starting to be equipped to detect such mutations with genomic surveillance in a manner relevant to pandemic mitigation and the prevention of sub-pandemics of specific variants or types of variants. As of December 2020, contemporary measures such as COVID-19 vaccines and medications seem to be effective in the treatment of infections with the tracked mutated variants compared to earlier forms that are closer to the original virus/es.{{cite news | vauthors = Zimmer C, Carey B |title=The U.K. Coronavirus Variant: What We Know |url=https://www.nytimes.com/2020/12/21/health/new-covid-strain-uk.html |access-date=16 January 2021 |work=The New York Times |date=21 December 2020}}{{cite web |title=WHO {{!}} SARS-CoV-2 Variants |url=https://www.who.int/csr/don/31-december-2020-sars-cov2-variants/en/ |archive-url=https://web.archive.org/web/20201231181601/https://www.who.int/csr/don/31-december-2020-sars-cov2-variants/en/ |archive-date=December 31, 2020 |website=WHO |access-date=16 January 2021}}{{cite news |title=Update On Covid-19 (18th December 2020) - SA Corona Virus Online Portal |url=https://sacoronavirus.co.za/2020/12/18/update-on-covid-19-18th-december-2020/ |access-date=16 January 2021 |work=SA Corona Virus Online Portal |language=en-ZA}}{{cite web | vauthors = Carlson AM, Nicholas HB |title=The unlikely prospect of a COVID-19 variant that outsmarts vaccines 'keeps me up at night,' CDC Director Rochelle Walensky says in The EIC Interview |url=https://www.businessinsider.com/cdc-head-covid-escape-variant-keeps-me-up-at-night-2021-8 |website=Business Insider |access-date=12 August 2021}} Tools used in the pandemized outbreak of COVID-19 included PANGOLIN{{cite journal | vauthors = Hirotsu Y, Omata M | title = SARS-CoV-2 B.1.1.7 lineage rapidly spreads and replaces R.1 lineage in Japan: Serial and stationary observation in a community | journal = Infection, Genetics and Evolution | volume = 95 | pages = 105088 | date = November 2021 | pmid = 34560289 | pmc = 8454025 | doi = 10.1016/j.meegid.2021.105088 | bibcode = 2021InfGE..9505088H }} and Nextstrain.{{cite journal | vauthors = Mercatelli D, Holding AN, Giorgi FM | title = Web tools to fight pandemics: the COVID-19 experience | journal = Briefings in Bioinformatics | volume = 22 | issue = 2 | pages = 690–700 | date = March 2021 | pmid = 33057582 | pmc = 7665357 | doi = 10.1093/bib/bbaa261 | quote = The architecture of Nextstrain is well designed and responds to the need for a continual surveillance to prevent uncontrolled outbreaks. }}{{relevance inline|date=June 2022}} In July 2021, scientists reported the detection of anomalous unnamed unknown-host SARS-CoV-2 lineages via wastewater surveillance.{{cite news |title=Detecting novel SARS-CoV-2 variants in New York City wastewater |url=https://medicalxpress.com/news/2022-02-sars-cov-variants-york-city-wastewater.html |access-date=10 March 2022 |work=University of Missouri |language=en}}{{cite journal | vauthors = Smyth DS, Trujillo M, Gregory DA, Cheung K, Gao A, Graham M, Guan Y, Guldenpfennig C, Hoxie I, Kannoly S, Kubota N, Lyddon TD, Markman M, Rushford C, San KM, Sompanya G, Spagnolo F, Suarez R, Teixeiro E, Daniels M, Johnson MC, Dennehy JJ | display-authors = 6 | title = Tracking cryptic SARS-CoV-2 lineages detected in NYC wastewater | journal = Nature Communications | volume = 13 | issue = 1 | pages = 635 | date = February 2022 | pmid = 35115523 | pmc = 8813986 | doi = 10.1038/s41467-022-28246-3 | bibcode = 2022NatCo..13..635S }}

A problem with the surveillance for mutated variants during the COVID-19 pandemic was that entities don't have sufficient incentives (and/or requirements) to report such variants. A global treaty proposed by the E.U. includes such incentives. A further issue was that vaccines did not provide a high enduring protection against the variants. One approach to solve this problem are pan-virus vaccines that protect against many strains (in this case a pan-SARS-CoV-2-like/variant-coronavirus vaccine), possibly including variants that do not yet exist.{{cite news |title='This May Not Be The Big One': Army Scientists Warn of Deadlier Pandemics to Come |url=https://www.defenseone.com/technology/2021/06/may-not-be-big-one-army-scientists-warn-deadlier-pandemics-come/174853/ |access-date=6 June 2022 |work=Defense One |language=en}}

The increased pressure on ecosystems is being driven by the "exponential rise" in consumption and trade of commodities such as meat, palm oil, and metals, largely facilitated by developed nations, and by a growing human population. According to Peter Daszak, the chair of the group who produced the report, "there is no great mystery about the cause of the Covid-19 pandemic, or of any modern pandemic.

In a paywalled article, American scientists proposed policy-based measures to reduce large risks from life sciences research – including pandemics through accident or misapplication. Risk management measures may include novel international guidelines and standards of conduct, effective oversight, improvement of US policies to influence policies globally, and identification of gaps in biosecurity policies along with potential approaches to address them.{{cite web |title=Forschung an Krankheitserregern soll sicherer werden |url=https://www.sciencemediacenter.de/alle-angebote/research-in-context/details/news/forschung-an-krankheitserregern-soll-sicherer-werden/ |website=www.sciencemediacenter.de |access-date=17 January 2023 |language=en}}{{cite journal | vauthors = Pannu J, Palmer MJ, Cicero A, Relman DA, Lipsitch M, Inglesby T | title = Strengthen oversight of risky research on pathogens | journal = Science | volume = 378 | issue = 6625 | pages = 1170–1172 | date = December 2022 | pmid = 36480598 | doi = 10.1126/science.adf6020 | s2cid = 254998228 | doi-access = free | bibcode = 2022Sci...378.1170P }}

Some also caution that simple bans may force traders underground, where they may pay less attention to hygiene and some state that it's wild animals rather than farmed animals that are the natural hosts of many viruses. National Geographic's Jonathan Kolby cautions about the risks and vulnerabilities present in the massive legal wildlife trade.{{cite web |title=To prevent the next pandemic, it's the legal wildlife trade we should worry about |url=https://www.nationalgeographic.com/animals/2020/05/to-prevent-next-pandemic-focus-on-legal-wildlife-trade/ |archive-url=https://web.archive.org/web/20200507192031/https://www.nationalgeographic.com/animals/2020/05/to-prevent-next-pandemic-focus-on-legal-wildlife-trade/ |url-status=dead |archive-date=May 7, 2020 |website=NationalGeographic |access-date=5 June 2020 |language=en |date=7 May 2020}} Helping ensure people are provided with viable and profitable alternatives to the wildlife trade is also important.{{cite news | vauthors = Felbab-Brown V |title=Preventing pandemics through biodiversity conservation and smart wildlife trade regulation |url=https://www.brookings.edu/research/preventing-pandemics-through-biodiversity-conservation-and-smart-wildlife-trade-regulation/ |access-date=3 February 2023 |work=Brookings Institution |date=25 January 2021}}
Some traditional medicines (i.e. traditional African medicine, TCM) still use animal-based substances. Since these can trigger zoonosis,[https://www.ifpri.org/blog/africas-growing-risk-diseases-spread-animals-people Africa's growing risk of diseases that spread from animals to people ] a possible prevention could be changes to handbooks for practitioners of such traditional medicines (i.e. exclusion of animal-based substances). Senior adviser and veterinary epidemiologist at the National Food Institute at the Technical University of Denmark Ellis-Iversen states that in agricultural animal health "outbreaks of exotic disease in well-regulated countries rarely get big because we identify and control them right away". New York City's Bronx Zoo's head veterinarian Paul Calle states that usually emerging infectious diseases from animals are the result from wildlife consumption and distribution on a commercial scale rather than a lone person hunting to feed their family.{{additional citation needed|date=June 2020}}

John Davenport advises to abandon widespread libertarian ideology which, according to him, "denies the importance of public goods or refuses to recognize their scope".

A review suggests that feeding the future human population would require increases in crop and animal production, albeit it is unclear which diets (e.g. future levels of meat production) they project.

Measures could include reducing meat production (except for potential cultured meat), de-intensifying livestock farming, reducing the use of antimicrobials, improving health and health-monitoring of livestock, increasing livestock biodiversity, further understanding of the genetic and functional basis of host adaptation,{{cite journal | vauthors = Mourkas E, Taylor AJ, Méric G, Bayliss SC, Pascoe B, Mageiros L, Calland JK, Hitchings MD, Ridley A, Vidal A, Forbes KJ, Strachan NJ, Parker CT, Parkhill J, Jolley KA, Cody AJ, Maiden MC, Kelly DJ, Sheppard SK | display-authors = 6 | title = Agricultural intensification and the evolution of host specialism in the enteric pathogen Campylobacter jejuni | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 117 | issue = 20 | pages = 11018–11028 | date = May 2020 | pmid = 32366649 | pmc = 7245135 | doi = 10.1073/pnas.1917168117 | doi-access = free | bibcode = 2020PNAS..11711018M }} improving occupational hygiene and safety of farming and food processing/food{{cite journal | vauthors = Aiyar A, Pingali P | title = Pandemics and food systems - towards a proactive food safety approach to disease prevention & management | journal = Food Security | volume = 12 | issue = 4 | pages = 749–756 | date = 1 August 2020 | pmid = 32837645 | pmc = 7351553 | doi = 10.1007/s12571-020-01074-3 }} (see also: HACCP and COVID-19 software (including contact tracing)).
== Culling ==
Experts warned that depleting the numbers of species by culling to forestall human infections reduces genetic diversity and thereby puts future generations of the animals as well as people at risk while others contend that it's still the best, practical way to contain a virus of livestock.{{cite journal | vauthors = Waltz E | title = Pandemic prevention schemes threaten diversity, experts warn | journal = Nature Medicine | volume = 12 | issue = 6 | pages = 598 | date = June 2006 | pmid = 16760992 | doi = 10.1038/nm0606-598a | s2cid = 1145076 | doi-access = free }} There are also other problems with culling and there are alternatives to it, such as animal vaccination.{{cite journal | vauthors = Butler D | title = Vaccination will work better than culling, say bird flu experts | journal = Nature | volume = 434 | issue = 7035 | pages = 810 | date = April 2005 | pmid = 15829925 | doi = 10.1038/4344810a | s2cid = 4347170 | doi-access = free | bibcode = 2005Natur.434..810B }}{{additional citation needed|date=February 2022}} There are also problems with the forms of culling-implementation such as livestock producers and subsistence farmers who are unable to access compensation being motivated to conceal diseased animals rather than report them.{{cite web | vauthors = Blackburn CC, Natsios AS, Parker Jr GW, Katz R, Osterholm MT, Laine GA, Fair J |title=Global leadership at the crossroads: Are we prepared for the next pandemic? |url=https://oaktrust.library.tamu.edu/handle/1969.1/169477 |publisher=Scowcroft Institute of International Affairs (The Bush School) |date=May 2018}}
Prevention versus mitigation
{{See also|Preventive healthcare}}
Pandemic prevention seeks to prevent pandemics while mitigation of pandemics seeks to reduce their severity and negative impacts. Some have called for a shift from a treatment-oriented society to a prevention-oriented one.{{cite journal | vauthors = Manika D, Golden L |title=Self-efficacy, Threat, Knowledge, and Information Receptivity: Exploring Pandemic Prevention Behaviors to Enhance Societal Welfare |journal=Academy of Health Care Management Journal |date=2011 |url=https://eprint.ncl.ac.uk/249545 |access-date=25 March 2020 |language=en}} Authors of a 2010 study write that contemporary "global disease control focuses almost exclusively on responding to pandemics after they have already spread globally" and argue that the "wait-and-respond approach is not sufficient and that the development of systems to prevent novel pandemics before they are established should be considered imperative to human health".{{cite journal | vauthors = Pike BL, Saylors KE, Fair JN, Lebreton M, Tamoufe U, Djoko CF, Rimoin AW, Wolfe ND | display-authors = 6 | title = The origin and prevention of pandemics | journal = Clinical Infectious Diseases | volume = 50 | issue = 12 | pages = 1636–1640 | date = June 2010 | pmid = 20450416 | pmc = 2874076 | doi = 10.1086/652860 | doi-access = free }} Peter Daszak comments on the COVID-19 pandemic, saying "[t]he problem isn't that prevention was impossible, [i]t was very possible. But we didn't do it. Governments thought it was too expensive. Pharmaceutical companies operate for profit". The WHO reportedly had mostly neither the funding nor the power to enforce the large-scale global collaboration necessary to combat it.{{cite web | vauthors = Kahn J |title=How Scientists Could Stop the Next Pandemic Before It Starts |url=https://www.nytimes.com/2020/04/21/magazine/pandemic-vaccine.html |website=The New York Times |access-date=8 June 2020 |date=21 April 2020}} Nathan Wolfe criticizes that "our current global public health strategies are reminiscent of cardiology in the 1950s when doctors focused solely on responding to heart attacks and ignored the whole idea of prevention". Nevertheless, measures that improve pandemic mitigation capabilities and preparedness for mitigation are important – for example the development of novel far-ultraviolet light could make sterilization "easy, routine and effective".{{cite news |title=The potential of far-ultraviolet light for the next pandemic |url=https://physicsworld.com/a/the-potential-of-far-ultraviolet-light-for-the-next-pandemic/ |access-date=3 February 2023 |work=Physics World |date=19 May 2020}}{{cite news | vauthors = Anthony A |title=William MacAskill: 'There are 80 trillion people yet to come.
