Certain areas of the Navajo nation surpass even New York City in the number of cases per 100,000 in these areas

The Kayenta and Chinle service areas have been the hardest hit, with more than 400  cases per every 10,000 residents as of Thursday evening.

In Kayenta, the rate per 10,000 residents is more than 500, which outpaces even the worst-hit ZIP codes in New York City. New York ZIP codes have far more COVID-19 deaths.
