Oct 16 (Reuters) – The US CDC on Friday reported 4,410 measles cases nationwide as of October 15, an increase of 330 ​from its last update a week ‌ago, as an outbreak of the highly contagious disease continues.

• Pennsylvania has reported 1,260 measles ​cases this year as of October 16, with 238 disease-related hospitalizations, according to state ⁠health department data
