By Julie Steenhuysen and Bhanvi Satija (Reuters) -A New Mexico resident who has died, tested positive for measles, the state health department said on Thursday, marking the second measles-related death in the United States in more than a decade.

An unvaccinated New Mexico man tested positive for measles after death, becoming what health officials say could be the second death reported in the ongoing outbreak that has infected over 160 people in at least nine states.

The New Mexico resident didn't seek medical care before dying, but the person tested positive for measles, state health officials said.
