Health officials confirmed another 41 measles cases last week, the Centers for Disease Control and Prevention said Monday, bringing the total to 880 for 2019, already the worst year for the disease since 1994.

The CDC said it has now confirmed measles in 24 states this year. While the total number continued to rise, the pace appears to be slowing down — although the agency will need to see if the trend continues before it can officially say the spread is slowing, a spokesman said.
