Covid-19 and contact tracing — an open source approach is vital

Excerpt from the article:

Matt Hancock has confirmed that a government contact tracing app will be trialled on the Isle of White from today. The app is designed to notify users that they have been in contact with actual or suspected cases of Covid-19, allowing them to follow enhanced social distancing and other appropriate actions like avoiding contact with people who are vulnerable. It then relies on the self-reporting of symptoms.
