ABSTRACT
OBJECTIVE: Describe patterns in the dissemination of fake news in the context of COVID-19 mortality and infodemic management in six Latin American countries. METHODS: A descriptive ecological study explored the percentage of the population that is unable to recognize fake news, the percentage who trust social network content, and the percentage who use it as their sole news source in Argentina, Brazil, Chile, Colombia, Mexico, and Peru, up to 29 November 2020. Internet penetration rate, Facebook penetration rate, and COVID-19 mortality were calculated for each country. Information was obtained from literature searches and government and news portals in the selected countries, according to the World Health Organization's five proposed action areas: identifying evidence, translating knowledge and science, amplifying action, quantifying impact, and coordination and governance. RESULTS: Chile and Argentina were the countries with the greatest internet penetration rates (92.4% and 92.0%, respectively) and were also among the heaviest users of social media as their only means of obtaining news (32.0% and 28.0%, respectively). Brazil and Colombia showed intermediate behavior for both indicators. Mexico had the highest use of social networks, while Peru and Colombia had the highest indices of inability to recognize fake news. CONCLUSIONS: It was observed that in countries with less use of social networks as the sole means for obtaining information and less trust in social network content, mortality was also lower.
OBJETIVO: Descrever o comportamento da disseminação de notícias falsas no contexto da mortalidade por COVID-19 e controle da infodemia em seis países latino-americanos. MÉTODOS: Estudo ecológico descritivo que explora o percentual da população com dificuldade de identificar notícias falsas, o percentual de confiança no conteúdo das redes sociais e o percentual de uso das redes como única fonte de notícias na Argentina, Brasil, Chile, Colômbia, México e Peru até 29 de novembro de 2020. Foram calculados o índice de penetração da internet, o índice de penetração do Facebook e a taxa de mortalidade por COVID-19 em cada país. Os dados foram obtidos por meio de pesquisas bibliográficas e em sites do governo e de notícias dos países selecionados segundo as cinco áreas de ação propostas pela Organização Mundial da Saúde (OMS): identificar a evidência, transmitir ciência e conhecimento, amplificar ações, mensurar o impacto e coordenação e governança. RESULTADOS: O Chile e a Argentina foram os países com os maiores índices de penetração da internet (92,4% e 92,0%, respectivamente) e estão entre os países com maior uso das redes sociais como única fonte de notícias (32,0% e 28,0%, respectivamente). O Brasil e a Colômbia tiveram um comportamento intermediário em ambos os indicadores. O México tem o maior uso das redes sociais e o Peru e a Colômbia apresentaram os maiores índices de dificuldade de identificar notícias falsas. CONCLUSÕES: Observou-se que, nos países com menor uso das redes sociais como única fonte para obter informação e menor confiança no conteúdo das redes sociais, a taxa de mortalidade também foi menor.
ABSTRACT
Resumen Introducción. La pandemia de COVID es un desafío para la vigilancia en salud pública y una oportunidad para evaluar sus fortalezas y debilidades en aras de mejorar la respuesta. Objetivo. Evaluar el desempeño del sistema de vigilancia en salud pública colombiano durante los primeros 50 días de la pandemia de COVID-19 en el país. Materiales y métodos. Se analizaron los datos publicados entre el 6 de marzo y el 24 de abril de 2020 por el Instituto Nacional de Salud y la Organización Mundial de Salud (OMS). Se consideraron en la evaluación: i) la calidad de los datos según la ley de Benford y ii) la oportunidad de la información, medida como la diferencia en fechas entre los datos generados en el Instituto Nacional de Salud y los recogidos en el informe situacional de la OMS. La variabilidad en el cumplimiento de la ley de Benford se evaluó con los valores de p en las pruebas de razón del logaritmo de la verosimilitud, ji al cuadrado o exacta de Moreno. Resultados. Hasta el 24 de abril hubo 4.881 casos de COVID-19 en Colombia. En la mayoría de los primeros 50 días se cumplió la ley de Benford, excepto en los primeros días de la epidemia. La diferencia entre los informes del Instituto Nacional de Salud y la OMS ha dependido, en gran medida, de la diferencia en los horarios de cierre de la información. Conclusión. En general, el sistema de vigilancia en salud pública colombiano cumplió con la ley de Benford, lo cual sugiere que hubo calidad en los datos. En futuros estudios que comparen el desempeño de los departamentos y distritos se podrá mejorar el diagnóstico de la vigilancia en salud pública del país. Introduction: The COVID pandemic is a challenge for public health surveillance and an opportunity to assess its strengths and weaknesses to improve the response. Objective: To evaluate the performance of the Colombian public health surveillance system during the first 50 days of the COVID-19 pandemic in the country. Materials and methods: We analyzed the data published between March 6 and April 24, 2020, by the Instituto Nacional de Salud and the World Health Organization (WHO). We evaluated: i) the quality of the data according to the fulfillment of Benford's law, and ii) the timeliness of the information measured as the difference in dates between the data generated by the Instituto Nacional de Salud and WHO's situational reports. We assessed the fulfillment of Benford's law using the p values of the log-likelihood ratio, the chi square or Moreno's exact tests. Results: Until April 24 there were 4,881 cases of COVID-19 in Colombia. During most of the first 50 days of the pandemic, Benford's law was fulfilled except the first days of the epidemic. The difference between Instituto Nacional de Salud and WHO reports largely depends on the different reporting times. Conclusion: In general, the Colombian public health surveillance system fulfilled Benford's law suggesting that there was quality in the data. Future studies comparing the performance of the departments and districts will improve the diagnosis of the Colombian surveillance system.

ABSTRACT
Currently, the fast spread of COVID-19 is the cause of a sanitary emergency in Brazil. This situation is largely due to President Bolsonaro's denial and the uncoordinated actions between the federal and local governments. In addition, the Brazilian government has reported that it would change its method of sharing information about the pandemic. On June 6, 2020, the presentation of accumulated cases and deaths was stopped, and the Supreme Court of Brazil determined that the federal government should continue to consolidate and disseminate the accumulated figures of cases and deaths. However, doubt about the transparency of the data remained. We used data reported by the government from Situation Reports 38-209 of the World Health Organization to assess the Benford's law fulfillment as an indicator of data quality. This rapid evaluation of data quality during the ongoing COVID-19 pandemic in Brazil suggests that the Brazilian public health surveillance system had an acceptable performance at the beginning of the epidemic. Since the end of June, the quality of cumulative death data began to decrease and remains in that condition as of August 2020. A similar situation has existed since August, with the data of accumulated new cases.
