Circulation of Coronavirus Images: Helping Social Distancing?

As soon as the SARS-Cov2 disease was recognized by experts to potentially cause a serious pandemic, a three dimensional diagrammatic image of the virus, colored in strong red, conquered public media globally. This study confronts this iconic virus image with a historic image analysis of 33,000 biomedical articles on coronaviruses published between 1968-2020 and interviews with some of their authors. Only a small fraction of scientific virus publications entail images of the complete virus. Red as an alarm color is not used at all by scientists who don't aim for a non-scientific public. Circulation in this case concerns the movement of iconic images from a scientific context into a general public. On the basis of hps-studies on scientific diagrams and especially on color use in scientific diagrams to convey specific messages in public, the paper discusses the role of the claim of public corona-virus diagram as "scientific." It points at relevant differences between most frequent scientific corona-virus images and the diagrammatic image used in public. Both author- and readerships (in science and public) follow contrasting aims and values. Thus, the images meet non-expert readers for whom the images entail very different - and potentially unintended - meanings then to virus experts.
