Blood tests reveal broad extent of Zika infection

A new study shows that nearly half of the population of Managua, Nicaragua, has been infected with the Zika virus. Previous infection with the Zika virus imparts immunity to the disease and can help quell future outbreaks.

Study details how dengue infection hits harder second time around

One of the most vexing challenges in the battle against dengue virus, a potentially fatal mosquito-borne virus, is that getting infected once can put people at greater risk for a more severe infection down the road. A new study with UC Berkeley researchers details how the interaction between a person’s immune response and a subsequent dengue infection could mean the difference between getting a mild fever and going into a fatal circulatory failure.

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.

As jurisdictions plan reopening while COVID-19 still presents a threat, antibody testing to see the extent of exposure and possible immunity will be critical, but studies can and have been found to be flawed, so it's important to get the testing right. Dr. Eva Harris, a public health professor specializing in infectious diseases and vaccinology, is co-leading an extensive study of the Bay Area's exposure to the virus over time. Noting that not all so-called seroprevalence studies are created equal, she says it's important to be clear about that when discussing the implications of different studies' findings. Her study will monitor how seroprevalence and the number of asymptomatic infections in the community respond to changes in COVID-19 mitigation strategies. "I think that it's really important that many places do seroprevalence studies -- I'm super supportive of that," she says. "I also think it's incredibly important that people understand the limitations" of individual studies, she adds. "The study design and the test used and the interpretation have to be transparent to the [scientific] community, and there has to be some way to communicate that to the public." Read more about her study at Berkeley's School of Public Health. Another story mentioning this study appeared in the San Francisco Chronicle.
