The Maine CDC has identified another four measles cases as it launches a new dashboard for tracking cases.

The cases announced on Tuesday are all in Penobscot County and were detected in people who were not vaccinated.

Health officials say there are no new exposure locations or risks to the public because the new cases are linked to the first case reported in early February.

The Maine CDC says the new cases aren’t considered an outbreak, which is defined as three or more cases in unrelated households.

The Maine CDC said it was launching a measles dashboard at its website, but the link did not yet appear to be active as of Tuesday.
