The COVID-19 pandemic and the fake news: a literature review

Tiago Rosa Maria Célia Delduque Sandra Mara Campos Alves About the authors

Abstract

This article presents the results of the narrative review on fake news that occurred during the most critical period of the COVID-19 pandemic. A word search was carried out in the BVSMS, BVSalud, and Scielo databases, using the expression fake news AND COVID-19, notícia falsa AND COVID-19, and desinformación AND COVID-19, since these expressions addressed the two languages selected for the review: Portuguese and Spanish. The inclusion criterion favored articles that used the web as a source of research, published between 2020 and 2022. A total of 24 articles were analyzed, 14 written in Portuguese and 10 in Spanish. The year 2022 concentrated the largest number of publications (n=11), and we concluded that social networks are the vehicles for the greatest dissemination of this type of information. The spread of fake news during the second year of the COVID-19 pandemic was as worrying as the disease itself, but the literature has not explored sufficiently the phenomenon that still follows the pandemic still underway. Most of the analyzed texts advised to the use of the news dissemination strategy to disseminate useful information about health, concluding that the analyzed studies demonstrated that the false news were incomplete or misleading, but most were unintentional.

Keywords:
Pandemic; Disinformation.COVID-19; Health Communication.

Introduction

On January 30, 2020, the World Health Organization (WHO) declared that the coronavirus outbreak was a Public Health Emergency of International Concern (PHEIC), considered by the International Health Regulations (IHR) to be the highest level of alert. On March 11, 2020, the WHO recognized the spread of COVID-19 as a pandemic (WHO, 2020WHO - WORLD HEALTH ORGANIZATION. Coronavirus disease 2019 (COVID-19) - Situation Report 56. Geneve: WHO, 2020.; WHO, 2023aWHO - WORLD HEALTH ORGANIZATION. Declaración sobre la tercera reunión del Comité de Emergencia del Reglamento Sanitario Internacional (2005) sobre el brote de la enfermedad por coronavirus (COVID-19). Organización Mundial de la Salud, [s. l.], 2023.

Acesso em: 9 ago. 2023.

). In the same period, and due to the high circulation of journalistic and non-journalistic information on the internet, the term “infodemic” was coined to refer to “an overabundance of information-some accurate and some not-that makes it hard for people to find trustworthy sources and reliable guidance when they need it” (WHO, 2023b)WHO - WORLD HEALTH ORGANIZATION. Infodemic. World Health Organization, [s.l.], 2023b. Disponível em: <Disponível em: https://www.who.int/health-topics/infodemic#tab=tab_1 >. Acesso em: 23 jun. 2022.

.

Infodemic differs from so-called fake news in that, in the former, the information comes from various sources, reliable or not, while fake news are characterized as news articles that are intentionally and verifiably false, and could mislead readers (Ross et al., 2021ROSS, J. R. et al. Fake News e Infodemia em tempos de covid-19 no Brasil: indicadores do Ministério da Saúde. Revista Mineira de Enfermagem, v. 25, e1381, 2021. DOI: 10.5935/1415.2762.20210029
https://doi.org/10.5935/1415.2762.202100...
).

Far from being a novelty, the inaccuracy of information during the uncontrollable spread of a disease-causing virus is part of any pandemic scenario. The Spanish flu, for example, emerged during World War I and, due to the conflict scenario during the spread of the disease, the affected countries hid their health statistics from the international community, leading to the incorrect circulation of information, favoring the spread of the disease (Goulart, 2005GOULART, A. C. Revisitando a espanhola: a gripe pandêmica de 1918 no Rio de Janeiro. História, Ciências, Saúde, Rio de Janeiro, v. 12, n. 1, p. 101-142, 2005. DOI: 10.1590/S0104-59702005000100006
https://doi.org/10.1590/S0104-5970200500...
). In Brazil, the reaction to the Spanish flu was accompanied by misinformation and ignorance on the part of society, especially fueled by the press, increasing the population’s fear: the press alarmed the people even more, informing that the Spanish flu nurtured a much bigger danger and that the virus was an invention of the Germans, as a war tactic (Goulart, 2005)GOULART, A. C. Revisitando a espanhola: a gripe pandêmica de 1918 no Rio de Janeiro. História, Ciências, Saúde, Rio de Janeiro, v. 12, n. 1, p. 101-142, 2005. DOI: 10.1590/S0104-59702005000100006

Quandt et al. (2019)QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6. systematized fake news (Figure 1), clarifying that a basic differentiation considered: (1) the core content of the information (including textual information, images, audio elements, etc.); (2) meta-information (headlines, author information, tags, and keywords); and (3) contextual aspects (positioning, references to other articles, framing). All these elements can be subject to levels of falsehood, with discrepancies in factuality ranging from (1) misleading (but factually correct) information; (2) addition or exclusion of information (enrichment of facts by misleading or erroneous information or change of meaning by omission or exclusion of relevant information); to (3) complete fabrications without any factual basis. The systematization by Quandt et al. (2019)QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6. is also associated with the concept that these phenomena can originate from the negligence of the issuer of the news, intentionally or by accident.

However, the problem becomes even more complex because the dissemination of fake news protects the sender with a cloak of invisibility and unknowingness and preserves the identity of the replicators, hindering its control and correction.

Figure 1
Systematization of fake news

The frequent use of the term as a label to discredit news and challenge the discourse of the mainstream media or independent journalists, especially any displeasing news, becomes an additional complication. The indiscriminate use of the term can serve as a rhetorical means to cast doubt on a particular story, report, or news item or to undermine the trust in the entire communication system (Jack, 2017JACK, C. Lexicon of lies: terms for problematic information. New York: Data & Society Research Institute, 2017.).

Marwick and Lewis (2018MARWICK, A.; LEWIS, R. Media manipulation and disinformation online. New York: Data & Society Research Institute, 2018.) criticize the inflammatory use of the term “fake news” and point that the allegation of fake news is mainly aimed at casting doubt on unfavorable information.

Mata, Grigoleto, and Lousada (2020MATA, M. L.; GRIGOLETO, M. C.; LOUSADA, M. Dimensões da competência em informação: reflexões frente aos movimentos de infodemia e desinformação na pandemia da covid-19. Liinc em Revista, Brasília, DF, v. 16, n. 2, e5340, 2020. DOI: RoR
https://doi.org/RoR...
) state that in critical periods, such as pandemics, due to the large amount and rapid flow of information, the problem becomes more complex, since the information is not always accurate and access to reliable sources is difficult. Moreover, in the 21st century, fake news have an apparatus in their favor, with enormous power of dissemination, transmitting information at planetary speed and reach: the internet.

The World Wide Web enables the horizontality of voices that has democratized the emission of opinions, while also stimulating the impregnation of common sense, often creating fertile ground for adventurers and “lay experts” in fields that they do not formally master, almost all of whom are online (Mata; Grigoleto; Lousada; 2020MATA, M. L.; GRIGOLETO, M. C.; LOUSADA, M. Dimensões da competência em informação: reflexões frente aos movimentos de infodemia e desinformação na pandemia da covid-19. Liinc em Revista, Brasília, DF, v. 16, n. 2, e5340, 2020. DOI: RoR
https://doi.org/RoR...
). Finding “Google doctors,” “political scientists,” and experts who are exclusively informed by the mainstream media is effortless, making academic credentials superfluous to talk about any specific area in the information environment of the web, contributing to the spread of fake news. In fact, the so-called experts linked to the large media conglomerates are now being questioned by new sources of information, often by experts who are not preferred by the large media companies, even though they have the credentials to do so.

Moretzsohn (2017MORETZSOHN, S. D. “Uma legião de imbecis”: hiperinformação, alienação e o fetichismo da tecnologia libertária. Liinc em Revista, Brasília, DF, v. 13, n. 2, p. 294-306, 2017. DOI: 10.18617/liinc.v13i2.4088
https://doi.org/10.18617/liinc.v13i2.408...
) warns of the immediate duality of the leveling of knowledge behind the idea of horizontality on the web, which may suggest an obvious communication-a space where everyone has a voice-but which makes voices that do not hold a certain knowledge become a threat:

Apparently democratic and inclusive, the defense of this leveling of knowledge ends up resulting in the praise of ignorance, with the perverse result of disqualifying, as authoritarian, the voice of those who have developed the ability to argue. This disqualification leads to the loss of references that could contribute to public enlightenment. Politically, the result is usually disastrous. (Moretzsohn, 2017MORETZSOHN, S. D. “Uma legião de imbecis”: hiperinformação, alienação e o fetichismo da tecnologia libertária. Liinc em Revista, Brasília, DF, v. 13, n. 2, p. 294-306, 2017. DOI: 10.18617/liinc.v13i2.4088
https://doi.org/10.18617/liinc.v13i2.408...
, p. 302, our translation)

The concern about fake news in all areas of life in society is so great that Brazil created the National Network to Combat Disinformation (Rede Nacional de Combate à Desinformação - RNCD), a virtual space created and maintained by the Federal University of Rio de Janeiro (UFRJ) and other universities, agencies, communication networks, research groups, etc., which gathers information about disinformation on the web, denouncing and combating fake news.

Therefore, this study conducted a narrative review to understand the state of the art of fake news in relation to the COVID-19 pandemic, aiming to identify what has been researched and published on the topic.

Methodology

This is a qualitative study of a narrative literature review, suitable for discussing the state of the art of a given topic. It consists of an analysis of the literature without a rigorous and replicable methodology in terms of data reproduction and quantitative answers to specific questions, in line with Vosgerau and Romanowski (2014VOSGERAU, D. S. A. R.; ROMANOWSKI, J. P. Estudos de revisão: implicações conceituais e metodológicas. Revista de Diálogo Educacional, Curitiba, v. 14, n. 41, p. 165-189, 2014. DOI: 10.7213/dialogo.educ.14.041.DS08
https://doi.org/10.7213/dialogo.educ.14....
). This type of study is essential for updating human knowledge on a specific topic, highlighting new ideas, methods, and sub-themes that have received greater or lesser emphasis in the selected literature (Elias et al., 2012ELIAS, C. S. R. et al. Quando chega o fim? uma revisão narrativa sobre terminalidade do período escolar para alunos deficientes mentais. Revista Eletrônica Saúde Mental Álcool e Drogas, São Paulo, v. 8, n. 1, p. 48-53, 2012. DOI: 10.11606/issn.1806-6976.v8i1p48-53
https://doi.org/10.11606/issn.1806-6976....
).

Since this is a literature review on fake news and the COVID-19 pandemic, original articles in Portuguese and Spanish were retrieved, indexed in the databases of the Virtual Health Library of the Ministry of Health (BVSMS), the Virtual Health Library (BVSalud), and the Scientific Electronic Library Online (Scielo). The articles were selected from September to December 2022, using the first three years of the pandemic as a reference period.

The following Health Sciences Descriptors (DeCs) were used: “notícias falsas” AND “COVID-19”; “desinformación” AND “COVID-19”; and “fake news” AND “COVID-19,” as these expressions met the languages considered in this review. The terms were used in isolation and in combination, delimiting the established time interval.

The criteria used to include the publications were that the search terms were explicit in the abstract and that the methodology used any web channel to obtain data. Reviews, essays, communications, and documents other than the type chosen for this study were not considered. The articles were selected first by their abstracts and then by reading the entire content, excluding publications outside the scope of the review.

Flow of the selection process for articles on fake news and COVID-19 from 2020 to 2022

Results

Among the selected publications, articles in Portuguese prevailed, with 16 articles and only eight in Spanish. In 2022, more articles were published than in previous years. Chart 1 shows the particularities of the studies on fake news and COVID-19 selected in the databases chosen for the review.

Nieves-Cuervo et al. (2021)NIEVES-CUERVO, G. M. et al. Infodemia: noticias falsas y tendencias de mortalidad por covid-19 en seis países de América Latina. Revista Panamericana de Salud Publica, Washington, DC, v. 45, e44, 2021. DOI: 10.26633/RPSP.2021.44
https://doi.org/10.26633/RPSP.2021.44...
found that countries with a lower rate of internet use as the sole source of information also had lower mortality rates, showing that low digital inclusion, at least in the case of the spread of fake news about COVID-19, is advantageous. The situation described by the authors denies, to a certain extent, the systematization by Quandt et al. (2019QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6.) due to the lack of provision for non-information, which is different from disinformation. The lack of information has safeguarded mortality rates by COVID-19.

Barcelos et al. (2021BARCELOS, T. N. et al. Análise de fake news veiculadas durante a pandemia de covid-19 no Brasil. Revista Panamericana de Saúde Pública, Washington, DC, v. 45, e65, 2021. DOI: 10.26633/RPSP.2021.65
https://doi.org/10.26633/RPSP.2021.65...
) identified that fake news in the pandemic period were spread mainly via WhatsApp and Facebook, with Google Trends showing a 34.3% increase in searches using the term “fake news.” In the study by Moreno-Fleitas (2020)MORENO FLEITAS, O. E. La divulgación de la información en la encrucijada de la crisis del COVID-19 en Paraguay. Reacciones y trasmisión de datos falsos y científicos a través de las redes sociales y los medios masivos. Revista de la Sociedad Científica del Paraguay, Asunción, v. 25, n. 1, p. 58-85, 2020. DOI: 10.32480/rscp.2020-25-1.58-85
https://doi.org/10.32480/rscp.2020-25-1....
, the main source of news about the COVID-19 pandemic in Paraguay, leading to false information about the disease, was Facebook, confirming the result obtained by the study by García-Marín et al. (2022)GARCÍA-MARÍN, D.; MERINO-ORTEGO, M. Desinformación anticientífica sobre la covid-19 difundida en Twitter en Hispanoamérica. Cuadernos.info, Santiago, n. 52, p. 24-46, 2022. DOI: 10.7764/cdi.52.42795

.

Analyzing the phenomenon in Spain and Italy, Ascacíbar, Malumbres, and Zanni (2021)ASCACÍBAR, G. P.; MALUMBRES, E. B.; ZANNI, S. Fact checking durante la covid-19: análisis comparativo de la verificación de contenidos falsos en España e Italia. Revista de Comunicación, Piura, v. 20, n. 1, p. 197-215, 2021. DOI: 10.26441/RC20.1-2021-A11
https://doi.org/10.26441/RC20.1-2021-A11...
showed that in Spain, in 2021, the website evaluated included 365 cases, of which 14% were false alerts, 34% misinformation, 43% lying manipulations, and 9% others. In Italy, the authors identified 225 cases, with 9% categorized as false alarms, 37% as misinformation, 51% as lying manipulations, and 3% in the “other” category.

Social networks and their algorithms prioritize the engagement of certain people, which can facilitate the spread of fake news, since this information generates emotional reactions and shares. Quandt et al. (2019)QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6., when systematizing the level of falsehood in studies, placed the intentionality of the dissemination of misleading information as the apex of the dissemination of lies, and the 2021 study in Spain and Italy by Ascacíbar, Malumbres, and Zanni (2021)ASCACÍBAR, G. P.; MALUMBRES, E. B.; ZANNI, S. Fact checking durante la covid-19: análisis comparativo de la verificación de contenidos falsos en España e Italia. Revista de Comunicación, Piura, v. 20, n. 1, p. 197-215, 2021. DOI: 10.26441/RC20.1-2021-A11
https://doi.org/10.26441/RC20.1-2021-A11...
clearly showed that this peak was reached. Moreover, the lack of media literacy, with low ability to critically evaluate information and sources, causes the spread of fake news.

Ribeiro et al. (2022)RIBEIRO, T. S. et al. Comunicação em saúde sobre covid-19 e diabetes mellitus em mídias sociais: verdadeiro e falso. Revista da Escola Anna Nery, Rio de Janeiro, v. 26, n. spe, e20210358, 2022. DOI: 10.1590/2177-9465-EAN-2021-0358
https://doi.org/10.1590/2177-9465-EAN-20...
, based on media channels, searched for news about diabetes mellitus and its relationship with COVID-19, showing a concern about whether the news were based on scientific evidence or not. After a survey on Twitter, they found that 80% of the news broadcasts were false and without sources of consultation, with emphasis on the indication of foods that could prevent contamination by the virus, such as lemon tea with bicarbonate, recipes with coconut oil, cannabidiol oil, etc. In conclusion, they highlight the need to transpose the “language of science” to the community as a better way of communicating health.

Pereira Neto et al. (2022)PEREIRA NETO, A. et al Avaliação da qualidade da informação de sites sobre Covid-19: uma alternativa de combate às fakenews. Saúde em Debate, Rio de Janeiro, v. 46, n. 132, p. 30-46, 2022. DOI: 10.1590/0103-1104202213202

argue that evidence-based online health information can reduce the use of health services with an impact on self-care practices, self-management, and adherence to treatment. However, in their research on four official Mato Grosso government websites, the information in the health area was of poor quality and essential data on COVID-19 were missing, such as the use of masks, hand washing, and the use of alcohol gel. Thus, aware of the fight against fake news, the government websites of the studied state were deficient and did not meet the minimum quality criteria, presenting incorrect, outdated, incomplete, and illegible information on the topic of health in general and COVID-19, in particular. In the systematization by Quandt et al. (2019)QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6., disinformation disseminated unintentionally is not the most serious level of fake news, although we agree that any disinformation-in this case, omission of information-may harm patients.

conducted a descriptive study on the use of the WHO’s massive open online course (MOOC), which in Brazil was offered by the Lumina platform of the Federal University of Rio Grande do Sul (UFRGS), as a powerful strategy for communication, scientific dissemination, and confronting the infodemic and fake news about COVID-19. These efforts highlight the importance of media literacy education to reduce the spread of fake news.

https://doi.org/10.1590/1413-81232022275...
, in their quantitative empirical study, checked a sample of 253 reports on vaccines and COVID-19, using the Eu Fiscalizo app. The study found that the Coronavac vaccine, produced by the Butantan Institute in partnership with the Sinovac company, was the immunizer with the most fake news about adverse effects, and at least 70% of Brazilian municipalities recorded cases of people who wanted to choose the brand of vaccines, refusing Coronavac. Cinelli et al. (2020CINELLI, M.; QUATTROCIOCCHI, W.; GALEAZZI A. The covid-19 social media infodemic. Scientific Report, v. 10, n. 1, e1698, 2020. DOI: 10.1038/s41598-020-73510-5
https://doi.org/10.1038/s41598-020-73510...
), analyzing the role of social media, confirmed the conclusion of the study, stating that misinformation spreads faster and is more resistant to correction than information.

present important data, such as the Digital Report 2021 (Global Overview Report), which showed that 75% of the Brazilian population uses the internet, corresponding to 158 million Brazilians connected to the network in 2019, with an average connection time of nine hours per day. From the analysis of a fact-checking agency, the authors highlight that fake news about COVID-19 is not only a problem in the field of communication or public and collective health: they include aspects that involve automation, the use of algorithms, and social bots, but have as background aspects related to the growth of digital networks and hyperpoliticization. They suggest that adequate public policies are needed to confront this phenomenon and that artificial intelligence and automation-the same “weapons”-can also be used as dissemination strategies.

https://doi.org/10.1590/1981-5271v46.2-2...
, after analyzing 107 occurrences, listed fake news attributed to fact-checking services, such as Fato ou Fake, Farsas.com, and Boatos.org, and on the WHO and Ministry of Health websites. They found 41 news items, all indicating unproven medications, and highlighted that disinformation influencers have been presented as an association between agents and platforms. The agents are governments, politicians, companies, journalists, YouTubers, bloggers, social bots, conservative religious groups, artists, scientists, and even health workers. The platforms that spread disinformation are Amazon, Apple, Google, Facebook, blogs, Pinterest, YouTube, WhatsApp, Twitter, Instagram, and Telegram, besides conventional media such as television, radio, and part of the press.

In line with Quandt et al. (2019)QUANDT, T. et al. Fake News. In: VOS, T. P.; HANUSCH, Folker. The International Encyclopedia of Journalism Studies. Hoboken: John Wiley & Sons, 2019. p. 1-6., this review showed that meta-information, along with the core content of the messages observed, is disclosed in an incomplete and even misleading manner. However, we did not prove the intentionality of the spread of false news, leading to believe that the phenomenon points more to a negligent posture of news disseminators, due to the lack of mechanisms for immediate verification of published statements. In the European Union, on the other hand, Ascacíbar, Malumbres and Zanni (2021ASCACÍBAR, G. P.; MALUMBRES, E. B.; ZANNI, S. Fact checking durante la covid-19: análisis comparativo de la verificación de contenidos falsos en España e Italia. Revista de Comunicación, Piura, v. 20, n. 1, p. 197-215, 2021. DOI: 10.26441/RC20.1-2021-A11
https://doi.org/10.26441/RC20.1-2021-A11...
) identified in Spain and Italy the disclosure of lies and notably malicious news about COVID-19.

Final considerations

The sample used in this study is not representative of all intellectual production, since most articles are in English, a language not included in the methodology. Moreover, a review does not provide the exact dimension of a problem, especially if it is of recent occurrence. Longitudinal studies are needed to confirm the temporal and causal relationships of the phenomenon.

The topic of fake news and COVID-19 is little addressed in the academic and scientific world, although it has been explored intensively on social networks and the mainstream media. Thus, more academic studies on the topic were expected. From the conclusions of the studies selected for this review, the concern with the phenomenon that affected and is still affecting the health policy sector was unanimous; nevertheless, many studies recognize and recommend an effort to use virtual means of communication as new ways of contact between the health sector and the population. Illustrating this position, Ferreira et al. (2022FERREIRA, F. V. et al. Uso de Python para detecção de fake news sobre a covid-19: desafios e possibilidades. Revista Eletrônica de Comunicação, Informação & Inovação em Saúde, [S. l.], v. 16, n. 2, p. 266-280, 2022. DOI: 10.29397/reciis.v16i2.3253.
https://doi.org/10.29397/reciis.v16i2.32...
) coined the expression “use the same weapons” as fake news, for the dissemination of useful and beneficial information for the health of the population.

Most of the news that circulated during the first three years of the pandemic, according to the review, were marked by unintentional disinformation, both in Brazil and in Latin American countries, unlike countries in the European Union, where deliberate lies circulated abundantly.

The pandemic ended, according to the World Health Organization, on May 5, 2023, but the corresponding disinformation is still ongoing, forcing the population, and especially health professionals, to be on permanent alert to neutralize this type of news.
