(Reuters) - The U.S. Centers for Disease Control and Prevention on Friday reported that weekly measles cases had jumped to 93 from 14 earlier, mainly driven by an outbreak in Texas. Your trusted source for the latest news delivered weekdays from the team at U.S. News and World Report.

According to the CDC, if you were born after 1957, one dose is considered sufficient to be considered protected from measles. Some adults may need a second dose. The CDC says adults who are going to be in high-risk settings for transmission should make sure they’ve had two doses at least 28 days apart.

As Texas continues to battle a growing measles outbreak largely among its unvaccinated children, six other states have confirmed cases, as well.
