WINDOW ROCK, Ariz. (AP) — The Navajo Nation has reported 12 new COVID-19 cases and one additional death.

Tribal health officials said the latest numbers released Saturday night push the total number of cases since the pandemic began more than a year ago to 30,590 on the vast reservation that covers parts of Arizona, New Mexico and Utah.

The known death toll now is at 1,284.

Navajo Nation President Jonathan Nez said more than half of the reservation’s adult population has been vaccinated, but people still need to stay home as much as possible, wear masks and avoid large gatherings.

The Navajo Department of Health recently loosened some virus-driven restrictions and transition to “yellow status.”

Restaurants are allowed to have in-door dining at 25% capacity and outdoor dining at 50% capacity and parks are permitted to open at 25% capacity but only for residents and employees.

Navajo casinos are open at 50% capacity, but only for residents and staff.
