Tribal health officials said the latest figures bring the total number of cases since the pandemic started to 30,095 with the known death toll remaining at 1,247.
The number of infections is thought to be far higher than reported because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick.
The Navajo Nation reservation covers parts of Arizona, New Mexico and Utah.
Tribal president Jonathan Nez said in a statement that federal medical officials continue to caution against lifting restrictions too soon.
"We know of at least one variant on the Navajo Nation, but this should not discourage us at all," Nez said. "Instead it should serve to motivate us to do better and to keep taking all precautions. The safest place to be is at home here."
In order to protect yourself from a possible infection, the CDC recommends:
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth.
- Stay home when you are sick.
- Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
- Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
- Cover your mouth and nose with a cloth face cover when around others
- Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
- Monitor your health daily
Coronavirus in Arizona: Latest case numbers
Symptoms for coronavirus COVID-19 include fever, coughing, and shortness of breath. These, of course, are similar to the common cold and flu.
Expect a common cold to start out with a sore or scratchy throat, cough, runny and/or stuffy nose. Flu symptoms are more intense and usually come on suddenly, and can include a high fever.
Symptoms of COVID-19 may appear more slowly. They usually include fever, a dry cough and noticeable shortness of breath, according to the World Health Organization. A minority of cases develop pneumonia, and the disease is especially worrisome for the elderly and those with other medical problems such as high blood pressure, obesity, diabetes or heart conditions.
To protect yourself, wash your hands well and often, keep them away from your face, and avoid crowds and standing close to people.
And if you do find yourself showing any of these flu or coronavirus symptoms - don't go straight to your doctor's office. That just risks making more people sick, officials urge. Call ahead, and ask if you need to be seen and where.
