Window Rock, Ariz. • Navajo Nation health officials on Monday reported 30 new confirmed cases of COVID-19 and six more deaths.

The latest numbers bring the total number of cases to 10,728 including two additional cases that was previously unreported due to delayed reporting. The known death toll now is at 571.

Tribal health officials said 112,648 people on the vast reservation that covers parts of Arizona, New Mexico and Utah have been tested for COVID-19 since the pandemic started and 7,343 have recovered.

A shelter-in-place order, mask mandate, daily curfews and weekend lockdowns remain in effect on the Navajo Nation.

Most people experience mild or moderate symptoms with the coronavirus, such as fever and cough that clear up in two to three weeks.

But for some — especially older adults and people with existing health problems — it can cause more severe illness, including pneumonia and death.
