Maine is now the 25th state to report a measles case in 2019, reports The Hill.
Four things to know:
1. Health officials confirmed the measles infection May 20, which marks Maine's first case since 2017.
2. The infection occurred in a school-age child who was vaccinated and has since recovered from the illness.
3. State CDC officials said Maine has one of the lowest vaccination rates among kindergarten-age students, which puts the state at higher risk of a measles outbreak.
4. As of May 17, the CDC has confirmed a record 880 measles cases nationwide.
