Window Rock, Ariz. • Navajo Nation health officials have reported 19 new confirmed cases of COVID-19 and three additional deaths.

That brings the total number of people infected to 9,519 with the known death toll at 487 as of Thursday.

Navajo Department of Health officials said 90,304 people have been tested for the coronavirus and 6,996 have recovered.

The Navajo Nation lifted its stay-at-home order last Sunday, but is encouraging residents to leave their homes only for emergencies or essential activities.

Much of the Navajo Nation has been closed since March as the coronavirus swept through the reservation that extends into New Mexico, Utah and Arizona.

The majority of people who are diagnosed with COVID-19 recover. For some people it causes mild or moderate symptoms, such as fever and cough.

But for others who contract the virus, especially those who are older or have underlying health conditions, it can cause more severe illness and death.
