Trucks blaring sound — like ice cream trucks — will roll through Boston neighborhoods Sunday, playing public service announcements about stopping the spread of COVID-19.

Mayor Marty Walsh says the goal is to reach as many people as possible.

The trucks will be broadcasting the message in seven different languages — English, Spanish, Hatian Creole, Vietnamese, Somali, Arabic and Cape Verdean Creole.

"Mayor Walsh has declared a public health emergency in the city of Boston," the messages say. "Stay home as much as you can. Wash your hands often. Cover your face when out, and keep your distance from others."

The trucks will focus on areas where coronavirus cases are the highest, like Hyde Park, Mattapan, Dorchester, East Boston, Roxbury and Roslindale.
