According to a survey published Wednesday, just 37% of Americans say they are bothered when people around them don't wear masks.
The proportion of people who said they were bothered when others didn't mask in public fell from 45% in November 2020 to 18% in May 2022.
In November 2020 the proportion of Americans who were bothered by businesses requiring masking shifted from 28% to 32%, but in May it went back up to 32%.
The proportion of Americans who wore masks all or most of the time in businesses plummeted from 61% in January to 30% in May, reflecting a dramatic decline in Covid-19 hospitalizations and deaths.
Since the initial surge subsided, mask-wearing has fallen among both Republicans and Democrats.
A majority of US adults think masks should be required on planes and public transport, including 80% of Democrats and 29% of Republicans.
The survey was done from May 2-8.
According to a poll published last month, just 46% of Americans support an airplane mask mandate, indicating that the public may be close to evenly divided on the issue. 80% of Democratic respondents said planes should have mask mandates, compared to only 4% of Republican respondents.
Americans have relaxed their attitudes toward Covid-19 response measures since the emergence of the less severe omicron variant and the decline in Covid-19 hospitalizations and deaths. The Transport Security Administration reported a 50% increase in Covid-19 infections among its workers in just two weeks after a federal judge struck down the federal government's mask mandate. The seven-day average of Covid-19 infections has risen by 152% over the past month, and Dr. Deborah Birx has warned of a spike in infections. There was a surge in Covid-19 in the US in April of 2021, followed by a surge in August and September of the same year.
The judge declared the federal public transportation mask mandate to be illegal.
