A 2nd measles-linked death in New Mexico. How should we respond?

USA Today has this reporting:

An unvaccinated adult in New Mexico tested positive for measles after dying, state health officials announced Thursday.

The patient would be the second measles death in 2025 — and the second in the United States in a decade — following an unvaccinated school-age child who died in late February in nearby West Texas amid a growing outbreak of nearly 160 people identified as infected from the highly contagious disease. The outbreak, which is suspected to have spread to eastern New Mexico, is the nation's largest in six years.

The New Mexico resident didn't seek medical care before dying, but the person tested positive for measles, according to a state Department of Health news release. The person's cause of death is under investigation.

Why do you think measles cases are on the rise in the USA? How should this new government respond to a potential outbreak of this virus?
