The following advice is from the Maine CDC site and here is their link https://www.maine.gov/dhhs/mecdc/infectious-disease/epi/airborne/coronavirus.shtml

The Maine CDC is preparing for the potential spread in Maine of the respiratory illness called COVID-19, caused by a novel (new) coronavirus. We urge Maine people to practice good hand hygiene, cover coughs and sneezes, and stay home if you are sick. If you are concerned that you have been exposed to COVID-19, call your health care provider, who will determine whether you should be tested and, as appropriate, submit a sample for testing.
