WINDOW ROCK, Ariz. – The Navajo Nation on Wednesday reported 80 more COVID-19 cases, but no coronavirus-related deaths for the 23rd time in the past 35 days.

The latest numbers pushed the tribe’s totals to 37,043 confirmed COVID-19 cases from the virus since the pandemic began more than a year ago.

The known death toll remains at 1,487.

Based on cases from Oct. 15-28, the Navajo Department of Health issued an advisory for 58 communities because of uncontrolled spread of COVID-19.

“With many of our students back in the classrooms, we strongly encourage all families to get their children vaccinated,” tribal President Jonathan Nez said in a statement. “The vaccines should be available at all health care facilities in the next few days … We are in this together and we need more of our people to get vaccinated to reduce the spread of COVID-19.”

The tribe’s reservation is the country’s largest at 27,000 square miles and covers parts of Arizona, New Mexico and Utah.
