On April 7, Facebook launched new tools that use "aggregated" and "anonymised" data on population movement, collected from users, that can show whether social distancing measures are working or when outbreaks are most likely to occur next.

The social connectedness index shows friendships across states and countries, which can help epidemiologists forecast the likelihood of disease spread, as well as where areas hardest hit by COVID-19 may need support.
