For all the recent talk about using phone location data to track the progress of the coronavirus epidemic, experts say the data is more likely to bolster longer-term research than provide much immediate help, at least in the U.S.

Driving the news: A Washington Post report Monday suggested that talks between the federal government and Facebook, Google and other tech companies could harness location data anonymously to combat the virus. But any such efforts would face major technical, practical, legal and ethical hurdles.

The big picture: Disease mapping has been a fundamental technique of modern public health efforts dating back to the birth of the field, during efforts to stem a cholera epidemic in Victorian London. GPS-enabled smartphones potentially give contemporary researchers a level of granular detail their predecessors couldn't imagine.

The catches:

Testing — The U.S. initially failed to test widely for the novel coronavirus, and there are continued test shortages.

  • No amount of location data can make up for missing infection data.
  • Anonymized fever data drawn from an app that has a million smart thermometers in use in the U.S., as the New York Times reports, might prove more valuable.

Precision — Today, a strong GPS signal gets you to within 5 yards' accuracy.

  • That's plenty to tell researchers whether an individual is, for instance, leaving home to visit another location.
  • But it's not good enough to "track whether people are keeping one another at safe distances to stem the outbreak," as the Washington Post story said.
  • It can't determine whether people are staying the recommended six feet away from others in public.

Consent — In the U.S., app makers generally must ask users for consent if they want to use location data. But most users checked that box long ago for at least a handful of key services, like Google's and Apple's mapping tools.

  • The apps, in turn, won't hand personalized data over to government unless they receive a court order.
  • Services like Facebook and Google do share some anonymized data with researchers under a variety of different sets of rules.

Other countries, particularly those without strong civil liberties traditions, are taking more aggressive approaches.

  • In China, the powerful machinery of a surveillance state fed by networks of devices and guided by AI algorithms has been turned against the epidemic.
  • In Israel, the cabinet approved emergency powers for the government to use phone data to track people who are infected with the coronavirus.

Another effort in the U.S. is a project in which the government is teaming with Palantir, the data-mining giant, to model the coronavirus outbreak, according to the Wall Street Journal. Other ideas under discussion include efforts to use facial recognition systems to trace individuals who have come into contact with the virus.

Our thought bubble: Today's tech-driven communications networks surely have a role to play in tracking the coronavirus. But other kinds of technology — like testing kits, ventilators, and vaccine research — are what count most in this fight. Our fascination with the magical power of smartphone data smacks of "technological solutionism" — the idea that for every real-world problem, there's an app-based cure.

Florida smashes single-day record for new coronavirus cases

Data: Covid Tracking Project; Chart: Axios Visuals

Florida reported 15,299 confirmed coronavirus cases on Sunday — a new single-day record for any state, according to its health department.

The big picture: The figure shatters both Florida's previous record of 11,458 new cases and the single-state record of 11,694 set by California last week, according to AP. It also surpasses New York's daily peak of 11,571 new cases in April, and comes just a day after Disney World reopened in Orlando.

Pelosi: Trump is "messing with the health of our children" with push to open schools

House Speaker Nancy Pelosi said on CNN's "State of the Union" Sunday that Education Secretary Betsy DeVos' aggressive push to fully reopen schools this fall is "malfeasance and dereliction of duty," accusing the Trump administration of "messing with the health of our children."

Why it matters: Trump has demanded that schools reopen as part of his efforts to juice the economy by allowing parents to return to work, despite caution from health officials that little is known about how the virus impacts children.
