Facebook unveils county-level maps of people with coronavirus symptoms

• "Since experiencing symptoms is a precursor to going to the hospital or becoming more seriously ill, these maps could be an important tool for governments and public health officials to make decisions on how to allocate scarce resources like ventilators and PPE, and eventually when it's safe to start reopening society," Zuckerberg added.
• The company plans to begin running the surveys globally this week, with the first results soon.

Zuckerberg writes today in a Washington Post op-ed that, in contrast to past global pandemics, "we have a new superpower: the ability to gather and share data for good."

• "If we use it responsibly, I’m optimistic that data can help the world respond to this health crisis and get us started on the road to recovery."
