WINDOW ROCK, Ariz. – The Navajo Nation on Thursday reported 14 new confirmed COVID-19 cases and one additional death.

It was the first reported coronavirus-related death in four days.

Tribal health officials said the latest figures pushed the total number of cases since the pandemic began more than a year ago to 30,677 on the vast reservation that covers parts of Arizona, New Mexico and Utah.

The known death toll now is 1,286.

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.

Nez said health care facilities on the Navajo Nation have begun to vaccinate adolescents in the 12-to-15 age range and some large-scale drive-thru vaccination events will be held Saturday.

“Our goal is to have at least 5,000 adolescents vaccinated by this weekend,” said Nez, who accompanied his 13-year-old son to Gallup Indian Medical Center on Thursday to receive his first dose of the Pfizer vaccine.
