WINDOW ROCK, Ariz. (AP) — The Navajo Nation has reported 183 additional COVID-19 cases with two deaths from the virus as of Sunday night.

The Navajo Nation is expecting 3,900 coronavirus vaccine doses to be delivered on Monday and Tuesday.

About 7,900 doses should arrive next week. Those vaccines will cover healthcare workers, emergency medical staff, traditional practitioners working in Indian Health Service facilities, and the staff and patients in long-term nursing facilities.

Tribal officials have said nearly all intensive care unit beds on the reservation are being used as COVID-19 cases surge.

The tribe has extended its stay-at-home order though Dec. 28 in an attempt to stop the spread of the virus.

In all, the tribe has reported more than 19,000 virus cases resulting in 720 deaths since the pandemic began.
