Health officials in Maryland have confirmed the state's first measles case for the year amid expanding outbreaks in Texas and New Mexico. The Maryland Department of Health said in a statement Sunday that a Howard County resident with recent international travel history has tested positive for the highly contagious disease.

Nearly 230 measles cases have been identified in outbreaks in West Texas and a nearby New Mexico county. One hundred ninety-eight measles cases have been reported in the West Texas outbreak, the Texas Department of State Health Services said in an update Friday — 39 more confirmed cases since an update on Tuesday.

A historic measles outbreak in West Texas is just short of 200 cases, Texas state health officials said Friday, while the number of cases in neighboring New Mexico tripled to 30. Most of the cases across both states are in people younger than 18 and people who are unvaccinated or have an unknown vaccination status.
