WINDOW ROCK, Ariz. – Navajo Nation health officials are reporting 133 new COVID-19 cases and seven more deaths as a revised public health order is set to take effect.

The latest figures released Sunday bring the total reported coronavirus cases on the reservation to 27,484 with 973 known deaths.

Beginning Monday, the tribe is extending its stay-at-home order with a revised nightly curfew to limit the spread of COVID-19. The Navajo Nation is also lifting weekend lockdowns to allow more vaccination events.

The actions in the latest public health emergency order will run through at least Feb. 15.

The daily curfew will run daily from 9 p.m. to 5 a.m.

Tribal officials said more than 228,000 people on the vast reservation have been tested for COVID-19 and more than 14,000 have recovered.

The Navajo Nation extends into Arizona, New Mexico and Utah.

The number of infections is thought to be higher than reported because many people haven’t been tested.

Studies suggest people can be infected with the virus without feeling sick.
