according to the Centers for Disease Control and Prevention.
That weekly increase of 41 cases is the smallest since the week ending March 14, when the total rose by 40. The largest 1-week rise of the year came during the week ending April 11, when there were 90 new cases, CDC data show.
A case that has been reported by the media in the last week but not officially through the CDC would make New Mexico the 25th state with a measles case this year. The state’s health department has confirmed measles in a 1-year-old from Sierra County, which is New Mexico’s first case since 2014, the Las Cruces Sun News reported, adding that 4,441 school-aged children had an exemption for vaccination filed with the state in 2018.
Making a return appearance to the CDC’s list of outbreaks is Washington State, which reported six new cases last week in three Puget Sound counties (King, Pierce, and Snohomish). The most likely location and date of exposure was at Seattle-Tacoma International Airport on April 25, the Washington State Department of Health said. In February and March, there were 71 cases in Clark County on the state’s border with Oregon.
The ongoing outbreak in Michigan had been quiet since April, but the state’s Department of Health and Human Services confirmed a measles case in St. Clair County on May 17, bringing the total to 44 for the year. The new case, which is not related to an earlier outbreak that occurred mainly in Oakland County, involves an international traveler visiting Michigan.
