BOSTON (AP) — Four more people in Massachusetts have died from COVID-19, the illness caused by the coronavirus, bringing the state total to nine.

Charlie Baker has ordered all nonessential businesses to close at noon on Tuesday and remain closed until at least April 7 in an effort to slow down the spread of the coronavirus.
