Californians reported slightly lower rates for always wearing a face mask when leaving their homes during the month of May, before the Delta variant caused a sharp rise in coronavirus infections, according to data released this week from UCLA’s 2021 California Health Interview Survey (CHIS).

The latest update to the 2021 CHIS Preliminary COVID-19 Estimates Dashboard, which includes data collected from March through May, has questions on risk reduction behaviors—frequency of wearing face masks, hand washing or sanitizing, maintaining physical distancing, gathering with individuals outside of the household, and following safety guidelines during those times—as well as on views of the vaccine, testing and treatment.

The March and April estimates were released last month.

The results showed that 79.1 percent of adults statewide said they “always” wore a face covering, compared to 84.8 percent during March and April. Meanwhile, 65.8 percent of adults who didn’t plan on getting the vaccine reported “always” wearing a face covering when leaving their homes.

Californians also reported higher rates of gathering with people outside of their household in the past 30 days. The report showed that 58.7 percent of adults said they gathered with people outside of their household, compared to 53.1 percent in March and April.

A little over 61 percent of individuals who had received at least one dose of the vaccine gathered with people outside of their homes, compared with 56.8 percent of adults who did not plan to get vaccinated, according to the survey.

As for attitudes about the vaccine, the data showed that fewer people reported that they would not get the vaccine—10.3 percent said they did not plan on getting the vaccine in May compared to 12 percent in March/April.

“We want the 2021 CHIS data to provide a clearer picture to help various groups in the state to safely navigate out of the pandemic as well as help individuals who are most in need of medical, personal, and financial support,” said Todd Hughes, CHIS director. “The data we’re compiling sheds light on areas and groups that need help, and how to assist them.”
