After more than two months at home, librarian Lisa Fagundes misses managing her sci-fi book collection so much, she feels she’s in withdrawal, longing to see new books, touch them, smell them. “It’s like a disease,” she said, laughing.

Instead, she’s been learning to combat a different disease: COVID-19. While libraries are closed, Fagundes is one of dozens of librarians training to become a contact tracer, calling people who have been exposed to the coronavirus and asking them to self-quarantine at home so they don’t spread it further.

Librarians are an obvious choice for the job, said Fagundes, who usually works at the information desk of the San Francisco Main Library. They’re curious, they’re tech-savvy, and they’re really good at getting people they barely know to open up.

“Because, a lot of times, patrons come up to you and they’re like, ‘Uhh, I’m looking for a book —’ and they don’t really know what they’re looking for or they don’t know how to describe it,” Fagundes said.

Or they’re teens afraid to admit out loud that they’re looking for books about sex or queer identity. Fagundes is used to coaxing it out of them in an unflappable, nonjudgmental way. Similar skills are needed for contact tracing, which involves asking people about their health status and personal history.

“Talking about sensitive subjects is a natural thing for librarians,” she said. “It’s a lot of open-ended questions, trying to get people to feel that you’re listening to them and not trying to take advantage or put your own viewpoint on their story.”

Fagundes is part of the first team of contact tracers trained through a new virtual academy led by the University of California-San Francisco. California awarded the university an $8.7 million contract in May to expand the academy and train 20,000 new contact tracers throughout California by July — one of the nation’s largest such efforts.

Gov. Gavin Newsom says counties need 15 contact tracers for every 100,000 residents to adequately contain the virus after stay-at-home orders are lifted.

Smaller contact-tracing teams have been able to manage the workload in recent months, while most people have been staying home. Local health officials said each new person who tests positive for the coronavirus was in close contact with an average of four or five people while infectious — typically family members and neighbors.

But as counties begin allowing businesses to reopen, a person’s average contacts will rise to 40, and will be much harder to locate, necessitating a larger workforce to identify and call them.

“You have a four- or five-day window to find people and get them isolated, which is what we do instead of treat them, because we don’t have treatment for COVID,” said Dr. George Rutherford, a UCSF professor of epidemiology who is leading the training effort.

The new training program takes 20 hours over the course of five days to complete and involves lessons on epidemiology and motivational interviewing, and demonstrations of how to make contact-tracing phone calls. Right now, all contact tracers work from home while on paid furlough or working part time at their regular jobs.

In addition to librarians, San Francisco has asked government employees from the tax assessor and city attorney offices to help out, including financial analysts, paralegals and investigators. Some rural counties have been recruiting sheriff’s deputies for the job.

“In other states they love to pick up people who worked as airline reservation agents, because they’re used to talking to people all day long and trying to work things out for them,” Rutherford said.

Megan Elliott is a manager in the San Francisco Assessor’s Office, where she oversees the valuation of real estate to figure out how much tax to charge. She is used to having conversations where she has to tell people things they don’t want to hear.

“For residential properties, a lot of times it has to do with a property owner who believes that we unfairly valued their new construction project,” she said. “So my job is to communicate to the taxpayers in a way that they can better understand why we do what we do and to help them see the reason and rationale behind that.”

It takes similar finesse to tell people that they’ve been in contact with someone who tested positive for the coronavirus and that they can’t go to work for the next two weeks. Elliott explains the importance of protecting the community from the virus, or the difference between quarantine (staying home if you’ve been exposed but aren’t symptomatic) and isolation (avoiding family members within your home if you do know you are sick).

Investigators from the city attorney’s office have been applying their people-finding skills. Some people who become ill may be reluctant to share information about their close contacts, or, they just don’t know enough information about the people they’ve been in close quarters with.

“Let’s say you’re on a job site, working construction, and you had lunch with a guy, ‘Oh, it’s Bob, he’s a steamfitter,’” said Rutherford. “That’s the kind of thing that we’re facing, that we get partial locating information.”

City investigators are familiar with databases and electronic gumshoe strategies for finding Bob’s last name and phone number, so he can be notified and get tested.

The goal is to train enough contact tracers to serve all 58 counties in California, but the state is leaving it up to each county to roll out the program and handle the specifics, such as what kind of support services to offer people asked to self-quarantine.

In San Francisco, when people who may be infectious are asked to stay home, contact tracers refer them to get tested, offer them free cleaning supplies and help with grocery and medication deliveries. If they can’t isolate themselves safely from other family members at home, residents have the option of staying in a city-funded hotel room.

San Francisco also plans to launch a program to help replace two weeks of lost income, up to $1,200, for people who test positive but don’t have a job with paid sick leave or cannot access unemployment insurance benefits.

South of San Francisco, in Santa Clara County, where the first COVID-19 cases in the U.S. were identified, health officials have struggled to recruit enough librarians and other county employees to become contact tracers. Officials are now asking for 800 volunteers from the community to meet their goal of building a 1,000-person case investigation and contact tracing team, with an emphasis on volunteers who can speak other languages, particularly Spanish and Vietnamese.

In San Francisco, some staffers from the city attorney’s office have been told they will eventually go back to their regular jobs part time and continue doing contact tracing part time. Librarian Lisa Fagundes has been doing four four-hour contact tracing shifts per week.

“It’s something that I feel like I could do for the rest of the year, if needed, then when the library starts ramping up, I could do both,” she said. “But, I think that the library will not be ramping up to full service anytime soon, because it’s not an essential service — as much as we may disagree.”
