The U.S. Centers for Disease Control and Prevention (CDC) reported on Friday, October 23, that measles cases in the United States had risen to 4,588 as of October 22, up 178 from a week earlier, as the outbreak of the highly contagious disease continues (GSM, via Reuters).
Measles-related hospitalizations this year stand at 479, according to the CDC, up from the 451 reported when GSM last updated the figures on October 20, when the national case count stood at 4,410.
Children and teenagers aged 5 to 19 are the largest group affected, with 1,914 cases, or 42% of all reported cases, followed by adults aged 20 and older at 1,881 cases, or 41%, CDC data showed.
