Boston Children’s Hospital and Harvard Medical School have set up a website to track COVID-19 information called “Covid Near You,” which was recently mentioned on Morning Edition on NPR. The site’s about section says it was created by epidemiologists and software developers at Harvard, Boston Children’s Hospital and a group of volunteers from across the technology industry. The site uses crowdsourced data to visualize maps to help citizens and public health agencies identify current and potential hotspots for the recent pandemic coronavirus, COVID-19. The website is a sister tool of Flu Near You, created by Ending Pandemics and Boston Children’s Hospital in 2012 and maintained by the Boston Children’s Hospital team.
Provision of data is voluntary, and you don’t need to provide any information to view their maps. At this writing, there have been no reports to them of anyone with symptoms on the island. Here’s a link: https://www.covidnearyou.org.
