Strained health agencies push do-it-yourself contact tracing

When Eileen Carroll’s daught er te sted positive for the coronavirus, Rhode Island health officials called with the results, then told her to notify anyone her daughter might have been around. Contact tracers, she was told, were simply too overwhelmed to do it.

That’s also why tracers didn’t call to warn the family that it had been exposed in the first place, said Carroll, of Warwick, Rhode Island. Luckily, she said, the relative with COVID-19 they had been around at Thanksgiving already alerted them.

“They said, ‘ We have 500 people a day and we cannot keep up with this,’” Carroll said.

It’s the same story across the U. S., as state and local health departments ask people who test positive to warn friends, family and co-workers themselves because a catastrophic surge in infections has made it difficult or impossible to keep up with the calls considered critical to controlling outbreaks.

Health officials say do-ityourself tracing is not ideal, but as infections and hospitalizations soar, it’s likely the most effective way to reach people who may be at risk.

Over 16.5 million people in the U. S. have been infected and more than 300,000 have died, and officials fear transmission will only get worse as people gather for the holidays.

Some health depar tments aren’t being informed of infections for several days, making it impossible to call at least 75% of a person’s contacts within 24 hours of a positive test, which experts say is necessary to control outbreaks. What’s more, many people won’t pick up the phone or refuse to answer questions when tracers call. Sometimes, there are simply too many positive tests to call everyone.

“If you don’t have the bandwidth to keep up, then you have to make strategic decisions ... and I think it’s a smart move,” Emily Gurley, an infectious disease epidemiologist at the Johns Hopkins Bloomberg School of Public Health, said of asking people to warn their own contacts.
