The U.S. Centers for Disease Control and Prevention on Friday reported that measles cases so far this year had jumped to 93 from 14 a week ago, mainly driven by an outbreak in Texas.

In Texas, at least 90 cases of measles have been reported in recent weeks across the northwest part of that state.

The measles outbreak in Texas has escalated sharply to 90 cases as health officials worry about the spread to more communities.
