It is effective through March 27, but officials said it could be extended.

Gov. Steve Bullock issued a statewide order Friday. Various counties in Montana had enacted similar actionan earlier.

The state has launched a phone line at 1-888-333-0461 and Montanans can also email questions to covid19info@mt.gov.

The governor declared a state of emergency March 12, which he said allows him to mobilize state resources.

On March 15 Bullock closed public schools until March 27, which he said would give schools time to plan for all the services students need such as meals. And he restricted visits to nursing homes to protect a vulnerable population.

People are told to stay home when sick, stay away from others who are ill, cover coughs and sneezes with tissue or elbow, wash hands often with soap and water or using hand sanitizer and disinfect surfaces often.
