The patient is a child who recently traveled internationally, and their vaccination status was not immediately known, according to county health officials.

The new cases in an unvaccinated adult and child come amid a statewide outbreak that has sickened almost 700 people since January, according to the Texas Department of State Health Services.

The Texas health department reported 683 cases of measles in the state today, an increase of 20 since April 29, as cases of the childhood disease surpass the 900-mark in one of the worst outbreaks in the country.
