Arizona health officials say they are tracking the state’s first travel-associated case of Clade I mpox. The case involves an Arizona resident who contracted the strain while traveling outside the country.

The Arizona Department of Health Services was notified this month and publicly announced the case on Wednesday. Officials described it as a unique mpox strain, marking a notable development for state health monitoring.

The update indicates the infection was linked to travel rather than local transmission inside Arizona. That distinction is important as health authorities follow the case and continue their response efforts.

The report adds Arizona to the list of places watching for mpox cases tied to international travel. State health officials are continuing to track the situation as more information becomes available.
