In the latest New York Times dispatch about the COVID-19 experience in California by students at Berkeley's Graduate School of Journalism, Max Brimelow, Julie Chang, Pedro Cota, Kristen Hwang and Alex Matthews write about new COVID-19 testing initiatives "led by health experts at California's top public and private universities," including a couple of Berkeley projects. They write: "The university health experts leading these efforts said they acted to fill a void. Eva Harris, an infectious disease specialist at the University of California, Berkeley, said that watching the virus spread around the world while bickering government leaders hesitated to act was like witnessing the Titanic speeding toward the iceberg. 'We finally just said, "OK, it hit," and still nothing happened, so we need to get involved,' she said. ... One of the most aggressive efforts currently underway to examine the extent of infection in homeless encampments is being led by the Innovative Genomics Institute, a biochemistry lab at the University of California, Berkeley, best known for its work at the forefront of the CRISPR gene-editing process, and Lifelong Medical Care, a community health center also based in Berkeley. The two have begun expanding testing to low-income and homeless populations in Alameda County. ... 'If we can't help the vulnerable, what are we doing?' asked Fyodor Urnov, the institute's scientific director for technology and translation. Not far from Dr. Urnov's office on the Berkeley campus, two professors in the School of Public Health have teamed up for a different kind of study. Dr. Harris, the infectious disease expert, and Lisa Barcellos, a genetic epidemiologist, are investigating the infection's spread throughout the Bay Area. ... They are testing thousands of residents to look for the presence of active Covid-19 virus as well as antibodies in the blood. This could reveal patients who were exposed but never showed symptoms, and it could also shed light on how widespread the disease truly is in California."

Dr. Eva Harris, a public health professor specializing in infectious diseases and vaccinology and Dr. Lisa Barcellos, a public health professor specializing in epidemiology and biostatistics, are co-leading an extensive study of the Bay Area's exposure to the virus to see how widespread it has been and for how long. On this program, they discuss their strategy, which includes a mailed questionnaire, followed up with testing. Dr. Harris says they've mailed 307,000 invitations to participate in the study to "every single home, every household in the census track in 11 cities." Dr. Barcellos says: "We're asking all about current symptoms, past symptoms and going back as far as December. We're asking about travel histories. We're asking about who's in the household and what they've been exposed to." From the respondents, 5,000 to 6,000 will be selected randomly to participate in the testing phase. "The in-home collection kits include all the materials that someone needs to collect saliva, as well as an oral and nasal swab," Dr. Barcellos says. "It's really very straightforward and doesn't hurt at all," Dr. Harris adds. Link to video. Read more about the study at Berkeley's School of Public Health.

A new Berkeley initiative, set to begin in early May and possibly continuing through the year, will test a large and representative sample of healthy East Bay residents to see if they have been exposed to the COVID-19 coronavirus. The tests will solicit saliva, swab and blood samples from volunteers between the ages of 18 and 60. The initiative addresses one of the key challenges faced in lifting physical distancing policies, since it's critical to know the full extent of viral spread with a disease that may be carried and spread by infected people without symptoms. "We're very excited about this ... We're going to follow people over time," says Dr. Eva Harris, a public health professor specializing in infectious diseases and vaccinology who is co-leading the project. Dr. Lisa Barcellos, a public health professor specializing in epidemiology and biostatistics, is co-leading the team. She says: "Our research is the first study in the Bay Area to identify and test a large, representative population of asymptomatic individuals, which will provide much-needed insight into transmission dynamics, the true extent of the community spread, and risk factors for infection beyond those tested for COVID-19 at hospitals and clinics."
