Survey data could help track future COVID-19 hot spots

WASHINGTON (AP) — Cameron Karosis usually strives to protect his personal information. But a scary bout of COVID-19 that began last month with headaches and fevers, progressed to breathing problems and led to a hospital visit has now left him eager to disclose as much as possible to help halt the virus’ spread.

Karosis has already shared personal details with Massachusetts health investigators. And if he was asked to comply with a disease-tracking phone app that monitored his whereabouts but didn’t publicly reveal his name and Cambridge street address, he said he’d do that, too.
