The Indian Health Service has updated its coronavirus data, showing results through January 16, 2022.

According to the data, 359,264 tests have returned positive for COVID-19, the disease caused by the coronavirus. That represents an increase of about 5.2 percent from the 341,643 cases previously reported by the IHS on January 12.

The comparison, though, is based on cumulative tests. Based on the 7-day rolling positivity rates, the number of cases reported by the IHS has increased more than 251 percent since December 25, 2021, and 81.8 percent since January 1, 2022.

Altogether, 3,798,390 coronavirus tests have been administered within the IHS, the results show. That represents an increase of 1.4 percent from four days prior.

Since mid-October of 2020, the IHS has been providing additional information about the spread of the coronavirus within the system. 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 highest rates have been seen in five areas. Two of them include the state of Arizona, indicating a disproportionate toll of COVID-19 in the state:

• Navajo Area — 15.1 percent
• Phoenix Area — 14.0 percent
• Oklahoma City Area — 13.8 percent
• California Area — 10.4 percent
• Albuquerque Area — 10.0 percent

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

Based on the 7-day rolling average positivity, all 12 IHS areas are seeing high COVID-19 rates, continuing the post-Christmas holiday surge across every region of Indian Country. 

• Tucson Area — 42.0 percent
• Oklahoma City Area — 39.1 percent
• Nashville Area — 38.2 percent
• Phoenix Area — 33.6 percent
• Great Plains Area — 33.0 percent
• Bemidji Area — 30.3 percent
• Navajo Area — 29.0 percent
• Portland Area — 25.2 percent
• Albuquerque Area — 23.9 percent
• California Area — 22.8 percent
• Alaska Area — 17.8 percent
• Billings Area — 16.0 percent

Overall, 10.1 percent of IHS tests have been positive since the onset of the pandemic, the data shows. Meanwhile, the 7-day positivity rate has dramatically jumped to 32.0 percent following a short period of declining rates. High rates, yet still far below the current 7-day rate, were seen in Indian Country starting in the summer of 2021.

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.

Beginning June 7, 2021, the IHS began updating its coronavirus data on a weekly basis. But as the number of COVID-19 cases grows again, the agency is updating results on Mondays and Thursdays. During the height of the pandemic throughout 2020 and the first half of 2021, results were provided by the IHS every day.
