Survey: Most Americans aren't answering the phone to avoid robocalls
Zoom out: State health departments across the U.S. use calls to perform contact tracing, which aims to help slow the spread of the coronavirus by encouraging quarantines and other precautions.
By the numbers: 4 billion robocalls targeted Americans in January alone, according to call-blocking company YouMail.
- That's 1,500 robocalls every second, or 12.2 calls for every person.
What's new: Pandemic-specific scams have been added to standard swindles about Social Security, auto warranties and credit cards.
