Boston Mayor Marty Walsh on Wednesday extended the city's coronavirus-related curfew to May 18.
The city's curfew began on April 6.
At least 8,613 cases of coronavirus have been reported in Boston, the mayor said. At least 333 people have died.
Walsh urged runners and cyclists to wear face coverings outside.
"This is not considerate to the people around you and I understand why it's making people angry. It's sending the message that you're not necessarily concerned about them in the community," he said.
