ABSTRACT

SARS-CoV-2, the virus that caused the COVID-19 pandemic, is genomically similar to a SARS-like beta-coronavirus found in Asian rhinolophid bats. This evolutionary relationship impressed the global media, which then emphasised bats as key actors in the spillover that resulted in the pandemic. In this study, we highlight changes in the traditional and new media coverage of bats and in Internet search volumes that occurred since the beginning of the COVID-19 pandemic in 2020.We analysed Google and Wikipedia searches for bats and coronaviruses in 21 countries and eight languages, as well as television broadcasts in the USA, some of which have global coverage, between January 2016 and December 2020. In January 2020, the amount of television news about bats boomed, and news associated with the term 'bat' shifted to COVID-19-related topics. A nearly identical pattern was observed in Google searches during 2020 at the global scale. The daily time series of television coverage and Internet search volumes on bats and coronavirus in the USA covaried in the first quarter of 2020, in line with the existence of a media bubble. Time-series analysis revealed that both the Google Trends index and visits to Wikipedia pages about bats boomed in early 2020, despite the fact that this time of year is usually characterised by low search volumes.Media coverage emphasised, correctly or not, the role of bats in the COVID-19 pandemic and amplified public interest in bats worldwide. The public image of these mammals, in many cases threatened and important ecosystem service providers, was seriously compromised. We therefore recommend that policymakers and journalists prioritise scientifically accurate communication campaigns about bats, which would help counteract the surge in bat persecution, and leverage interest towards positive human-bat interactions.


SARS­CoV­2, el virus causante de la pandemia COVID­19, es genómicamente símil al SARS­tipo beta­coronavirus encontrado en los murciélagos rinolófidos asiáticos. Esta relación evolutiva impresionó a los medios mundialmente, hasta tal punto que se ha enfatizado el papel de los murciélagos como uno de los principales vectores en la expansión de la pandemia. En este estudio, se resaltan los cambios producidos en la percepción de los murciélagos por los medios de comunicación (nuevos y tradicionales), y en las búsquedas en Internet que ocurrieron desde el inicio de la pandemia COVID­19 en 2020.Para ello se han analizado las búsquedas del término 'murciélago' en Google y Wikipedia en 21 países y ocho lenguas, así como las retransmisiones televisivas en EE.UU. (algunas de las cuales con cobertura global) entre enero 2016 y diciembre 2020. En enero 2020, la cantidad de noticias televisadas sobre murciélagos se disparó, y el número de noticias previamente asociadas con el término 'murciélago' cambiaron por temáticas relacionadas con el COVID­19. Un patrón idéntico puede ser observado a escala global en las búsquedas de Google durante el 2020. La serie temporal de cobertura televisiva y búsquedas en internet sobre murciélagos y coronavirus en EE.UU. covaría durante el primer cuarto del 2020, en líneo con la existencia de la burbuja mediática. El análisis de la cobertura diaria televisiva revela que tanto el índice Google Trend como las visitas a páginas de Wikipedia sobre murciélagos incrementaron al comienzo del 2020, a pesar de que esta época del año suele caracterizarse por bajos volúmenes de búsqueda.La cobertura mediática enfatizó, correctamente o no, el papel de los murciélagos en la propagación de la pandemia COVID­19, ampliando el interés público a lo largo del globo. La imagen pública de estos mamíferos, en muchos casos especies amenazadas o proveedoras de importantes funciones ecosistémicas, ha sido seriamente comprometida. Por lo tanto, se recomienda a periodistas y responsables políticos la priorización de campañas de comunicación científicamente fundamentadas que ayuden a contrarrestar este aumento en la persecución de los murciélagos aprovechando el interés actual para concienciar al público de sus interacciones positivas con el hombre.

ABSTRACT

In recent years, viruses similar to those that cause serious disease in humans and other mammals have been detected in apparently healthy bats. These include filoviruses, paramyxoviruses, and coronaviruses that cause severe diseases such as Ebola virus disease, Marburg haemorrhagic fever and severe acute respiratory syndrome (SARS) in humans. The evolution of flight in bats seem to have selected for a unique set of antiviral immune responses that control virus propagation, while limiting self-damaging inflammatory responses. Here, we summarize our current understanding of antiviral immune responses in bats and discuss their ability to co-exist with emerging viruses that cause serious disease in other mammals. We highlight how this knowledge may help us to predict viral spillovers into new hosts and discuss future directions for the field.
