Window Rock, Ariz. • Navajo Nation health officials report 69 new confirmed cases of COVID-19 but no additional deaths.

The total number of people infected on the reservation now stands at 8,837 with 434 known deaths as of Saturday night.

Tribal health officials said 76,902 people have undergone testing and 6,525 have recovered from the virus.

The latest weekend lockdown that includes the closure of businesses began after sunset Friday and will end early Monday morning. The tribe also has implemented daily and nighttime curfews.

Residents of the vast reservation that extends into Arizona, New Mexico and Utah have also been under a mandate to wear masks when out in public.

For most people, the new coronavirus causes mild or moderate symptoms, 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.
