There is a volunteer opportunity for helping the COVID-19 response. In order to help systematically investigate and respond to localized outbreaks, a tool for visualizing these transmission clusters is needed. This work would involve programming and ideally experience with data visualization. You would work with epidemiologists involved in current outbreak responses. Right now clusters are being plotted manually but an automated tool could speed up their processes and improve quality. To get a sense of what the desired output looks like, see Fig 1c of https://www.medrxiv.org/content/10.1101/2020.03.18.20034561v1.full.pdf or Fig 1 of https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30273-5/f... Ideally the output would be in a format, like powerpoint, that could be further edited by the epidemiologists. The level of work is hard to predict because it depends in part on what related software already exists, e.g. for phylogenetic trees, and how easy this is to adapt. A first version of a tool would ideally be usable within 1-2 weeks. For more information, please contact Aram Harrow <aram@mit.edu<mailto:aram@mit.edu>>.
