The number of measles cases reported in the U.S. this year has reached a twenty-year high, according to the CDC.
288 cases of measles have been reported to the CDC through May 23.
A majority of the cases are in Ohio, where there’s an ongoing outbreak in an Amish community.
Nearly all of the cases are linked to importation.
In the Amish outbreak, members of the community had recently traveled to the Philippines and brought the illness back.
Many of the ill had not been vaccinated.
CDC officials say it is imperative to realize measles is still present in other parts of the world.
The CDC is also warning travelers to get vaccinated.
