Protect privacy, equality and fairness in digital contact tracing with these key questions.
Technologies to rapidly alert people when they have been in contact with someone carrying the coronavirus SARS-CoV-2 are part of a strategy to bring the pandemic under control. Currently, at least 47 contact-tracing apps are available globally (see go.nature.com/2zc1qhk). They are already in use in Australia, South Korea and Singapore, for instance. And many other governments are testing or considering them.
Not really research, but a topical discussion on big data, privacy, consent and respect for persons, which are of significance to research.
What do COVID-19 contact-tracing apps do? Running on a mobile phone, they inform people that they have spent time near someone with the virus. The contacts should then respond according to local rules, for example by isolating themselves. Prompt alerts are key because the incubation time of the virus is up to two weeks.
