New estimates show unvaccinated adults least likely to wear a mask, engage in risk reduction behaviors

COVID-19 spurred lockdowns and mask mandates more than two years ago. However, data released today from the UCLA Center for Health Policy Research’s California Health Interview Survey (CHIS) show Californians were still taking precautions, such as wearing masks and avoiding large gatherings, in April 2022. About 2 in 5 (39%) California adults said they always wore a mask when leaving their home in the past week, 20% said usually, 24% said sometimes, and 16% said they never wore a mask.

With COVID-19 still raging, advice for parents on navigating back-to-school

With COVID-19 still very much present, Dr. Shira Shafir, UCLA Fielding School of Public Health associate professor of epidemiology and community health sciences, describes the start of the new school year in simple terms: “I think back-to-school is going to be a little funky.”

That description stems from her vast experience in epidemiology as well as being the mother of a boy who just turned 4.

"New studies say market is the only ‘plausible’ source of pandemic"

Not long after the World Health Organization and China released a report last year dismissing the possibility that the SARS-CoV-2 virus originated in a lab leak, scientists from major research institutions around the world noted the paucity of the published data, and advocated for a rigorous scientific investigation into the pandemic’s origins.

CNN interviewed Dr. Anne Rimoin, UCLA Fielding School of Public Health professor of epidemiology and the Gordon-Levin Endowed Chair in Infectious Diseases and Public Health, for a lengthy segment about the threats posed by COVID-19, monkeypox, Marburg, and other zoonotic infections.

"Most of U.S. population now in areas with high levels of COVID-19 subvariant BA.5"

More than half the U.S. population lives in counties where Covid-19 cases and hospitalizations are high enough that people should wear masks in indoor public settings, according to Centers for Disease Control and Prevention data.

The CDC’s latest assessment represents a significant jump from the week before, reflecting the added pressure that the easily spread Omicron BA.5 subvariant is putting on the U.S. since it became the dominant COVID-19 strain. Over a third of U.S. counties now fall into the CDC’s “high” category, up from one in five counties a week earlier.

UCLA researcher’s team finds COVID-19 tied to wildlife sales at Chinese market

An international team of researchers has confirmed that live animals sold at the Huanan Seafood Wholesale Market were the likely source of the COVID-19 pandemic that has claimed 6.4 million lives since it began nearly three years ago.

"China makes tweaks, but tough COVID policy still drags on economy"

 China has been tweaking its stringent COVID curbs but shows no sign of backing off from its "dynamic zero" policy, and has lagged in vaccination efforts that would enable it to do so, casting a heavy shadow over the world's second-largest economy.

The absence of a roadmap out of zero-COVID and expectations that it will persist well into 2023 leaves residents and businesses facing a prolonged period of uncertainty.

UCLA survey quantifies COVID-19 vaccine hesitancy among Californians

Despite the U.S. Food and Drug Administration's full approval of the COVID-19 vaccine, 58.8% of Californians who are not fully vaccinated are still worried about its side effects, according to a new UCLA survey.

"New Ultra-contagious Omicron Subvariants BA.4, BA.5"

The growing dominance of two new ultra-contagious Omicron subvariants is prolonging a wave of coronavirus cases in California and sparking growing concerns from health officials that coming weeks could see significant spread and increased hospitalizations.

BA.4 and BA.5 are now believed to be responsible for most new infections nationwide. The strains are of particular concern because they are not only especially contagious but also capable of reinfecting those who have survived earlier Omicron infection.

Jonah Stein exited the vaccination clinic in his father’s arms Tuesday afternoon, proud to show off his Band-Aid.

This “little booboo,” as the 2-year-old put it, was a long time coming. It marked the spot where he received his first dose of Moderna COVID-19 vaccine — much to the relief of his parents, who also have a 3-week-old at home.
