(CNN) About 40% of Asian and Black Americans say people have acted uncomfortable around them because of their race or ethnicity since the coronavirus pandemic began, according to a new report from the Pew Research Center.

For example, Ruiz said, 51% of Black adults said more people had expressed support for them because of their race or ethnicity during this period -- more than any other racial or ethnic group.

"About four-in-ten Black Americans (42%) and 36% of Asian Americans say they worry a great deal or a fair amount that other people might be suspicious of them because of their race or ethnicity if they wear a mask or face covering when in stores or other businesses.

"Despite these concerns, majorities of Black (69%) and Asian (80%) adults -- as well as white (62%) and Hispanic (74%) adults -- say they've worn a mask or a face covering all or most of the time in the past month when out in stores or other businesses."

And 30% of US adults think racist views about Black Americans are more common than before the pandemic.
