A new study from the University of California, Davis, Genome Center and UC San Francisco shows no significant difference in viral load between vaccinated and unvaccinated people who tested positive for the delta variant of SARS-CoV-2. It also found no significant difference between infected people with or without symptoms.

The findings underscore the continuing need for masking and regular testing alongside vaccination, especially in areas of high prevalence, the authors wrote. The study is currently available online as a preprint from MedRxiv.

One-third of recovered COVID-19 patients reported new or continuing symptoms two months after their positive tests, according to a study by graduate students in epidemiology at the University of California, Davis, in collaboration with the Long Beach Department of Health and Human Services. Women, people over 39, people with preexisting conditions and Black/African American persons had enhanced rates of “long COVID” symptoms.

With more than 41.5 million cases and a year and a half after the first confirmed COVID-19 case in the U.S, the search for a safe and effective cure to coronavirus continues.

As the pandemic spread around the globe, researchers at  the School of Medicine partnered with drug developers and funding agencies to find and test potential therapies and vaccines to SARS-CoV-2, the virus that causes COVID-19.

19 months and nearly 43 million cases after the first confirmed COVID-19 infection in the U.S., the search for safe and effective treatments continues at the UC Davis School of Medicine.

As the pandemic spread around the globe, researchers at the School of Medicine partnered with drug developers and funding agencies to find and test potential therapies and vaccines to SARS-CoV-2, the virus that causes COVID-19.

At the beginning of the COVID-19 pandemic, community health clinics saw a significant drop in patient visits. Important screenings like those for the hepatitis B virus (HBV) were getting missed, which was a setback for a local program called END B to end the transmission of HBV—a leading risk factor for liver cancer.

A UC Davis Health retrospective study published recently in Infection Control and Hospital Epidemiology shows how quickly COVID-19 infections were reduced among health care workers when vaccines were first distributed late last year.

While a life-altering pandemic has caused a substantial uptick in anxiety and depression symptoms among adults and children alike, LGBTQ+ youth have turned to peers in anonymous online discussion forums for support. New research from the University of California, Davis, suggests these LGBTQ+ teenagers — who already experience disproportionate levels of psychological adversity — exhibited increased anxiety on the popular r/LGBTeens subreddit throughout 2020 and the start of 2021.

As COVID-19 booster shots begin for those with compromised immune systems, researchers at the UC Davis School of Medicine continue to collect data from clinical trial participants. The goal is to help federal health authorities decide whether to expand vaccine booster shots to more people. 

Although people in early 2020 hoarded toilet paper, washed their hands incessantly, and wouldn’t leave home, 11 months later the public pushed the envelope on COVID-19 safety precautions and ignored warnings as time went on, a new University of California, Davis, study suggests.

The Association of Public and Land-grant Universities, or APLU, has honored the University of California, Davis, for its response through Healthy Davis Together to the coronavirus pandemic.

UC Davis joined one other institution, the University of Illinois at Urbana-Champaign, as the inaugural winners of the APLU Research Response to a Community in Crisis Award, announced Thursday (July 1).

A new study by UC Davis researchers confirms the low likelihood that SARS-CoV-2 contamination on hospital surfaces is infectious. The study, published June 24 in PLOS ONE, is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs. 

A new study from the University of California, Davis, and the Icahn School of Medicine at Mount Sinai confirms that surgical masks effectively reduce outgoing airborne particles from talking or coughing, even after allowing for leakage around the edges of the mask. The results are published June 8 in Scientific Reports.

A partnership between UC Davis and Maurice J. Gallagher, Jr., chairman and CEO of Allegiant Travel Company, has led to a new rapid COVID-19 test.

A recent study published Nature Scientific Reports shows the novel method to be 98.3% accurate for positive COVID-19 tests and 96% for negative tests.  

More than one in four COVID-19 patients develop long-haul symptoms lasting for months – even if they had mild cases, according to a handful of studies that have emerged recently. 

Doctors have been estimating one-quarter to one-third of COVID-19 patients become long haulers, as many patients call themselves. Now, four studies published since February confirm that range. They show that 27% to nearly 33% of patients who had COVID-19 but did not need to be hospitalized later developed some form of long-haul COVID. 

It may be our longing for friends and family. It may be instinctive. It may be that we’re exhausted. Whatever the reasons, many of us see familiar people as less of a COVID-19 risk, psychologists say. 

This phenomenon is not about people inside your household. And it reaches beyond social pods – which heath experts say are often iffy. New studies show that we almost instinctively drop our guard with people we know although we often have no clue about their health protocols.
