The Indian Health Service has updated its coronavirus data, showing results as of October 22, 2020.

According to the data, 65,253 tests have returned positive for COVID-19, the disease caused by the coronavirus. That represents an increase of 1.6 percent from the 64,216 cases previously reported by the IHS.

Altogether, 1,056,242 coronavirus tests have been administered within the IHS through October 22, the data shows. That marks an increase of almost 1.1 percent from the day prior.

Since the release of data from October 14, the IHS has been providing additional information about the spread of the coronavirus. The cumulative percent positive column shows the historical COVID-19 infection rate, meaning the number of tests that have returned positive since the onset of the pandemic.

Based on the cumulative percent positive, the Phoenix Area, the Navajo Area and the Tucson Area continue to show the highest rates. All three regions include the state of Arizona, indicating a disproportionate toll of COVID-19 in the state.

The 7-day rolling average positivity column offers a contemporary look at the impact of the coronavirus. The data shows where COVID-19 cases have been increasing more recently.

Based on the 7-day rolling average positivity, the Billings Area, the Great Plains Area and the Oklahoma City Area have seen dramatic increases in COVID-19 cases. The 7-day rate for the Billings Area, which serves IHS patients in the state of Montana and Wyoming, is a shocking 18.2 percent, according to the data.

Overall, 6.6 percent of IHS tests have been positive since the onset of the pandemic. The 7-day average is slightly higher, at 8.2 percent.

The data, however, is incomplete. While 100 percent of facilities run directly by the IHS are reporting data, only 33 percent of tribally managed facilities and 44 percent of urban Indian organizations are doing the same, the agency has told Indianz.Com.

The agency also provided to Indianz.Com the service population for 2019: 2,562,290. Based on that figure, 41.2 percent of American Indians and Alaska Natives have been tested for the coronavirus since the IHS began reporting data in March.

The IHS user population, on the other hand, is a much smaller number. As of 2019, 1,662,834 American Indians and Alaska Natives have lived within a service delivery area and have received health care at an IHS or tribal facility during the previous three years.

Based on the user population, 63.5 percent of Native Americans have been tested for the coronavirus since the IHS began reporting data in March.
