US measles cases jumped by a third over the past week, according to Centers for Disease Control and Prevention data, a worrying sign in the outbreak that’s already linked to two deaths.

• New Mexico’s health department listed Friday that an adult who had died and then tested positive for measles had succumbed to the disease, though the state’s medical examiner has yet to confirm the cause of death.
• If it was caused by measles, it would be New Mexico’s first such fatality in at least 40 years, according to the CDC.
• US cases since the beginning of the year rose by 58 to 222 across 12 states, the CDC reported, and 38, or 17% of those confirmed cases, have led to hospitalization.
