The Indian Health Service has updated its coronavirus data, showing results through December 11, 2021.

According to the data, 295,454 tests have returned positive for COVID-19, the disease caused by the coronavirus. That represents an increase of 1.1 percent from the 292,114 cases previously reported by the IHS on December 5.

Altogether, 3,498,391 coronavirus tests have been administered within the IHS, the results show. That represents an increase of about 1.2 percent from six 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 — 13.9 percent
• Phoenix Area — 12.9 percent
• Oklahoma City Area — 12.1 percent
• California Area — 10.1 percent
• Albuquerque Area — 9.7 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, 9 out of 12 IHS areas are seeing high COVID-19 rates, marking yet another instance of surges across every region of Indian Country. The 📈 red graph symbol indicates the areas in which positivity rates are on the rise, with multiple symbols indicating notable increases:

• Phoenix Area — 13.6 percent
• Albuquerque Area —11.8 percent📈
• Navajo Area — 11.8 percent
• Tucson Area — 10.4 percent📈
• Bemidji Area — 9.7 percent
• Great Plains Area — 8.5 percent
• Oklahoma City Area — 7.9 percent
• California Area — 7.4 percent
• Nashville Area — 6.9 percent

Notably, with the release of data from December 11, the Alaska Area finally fell below 5.0 percent positivity for the first time in several months. The region had seen a notable increase in cases, with the highest 7-day positivity of 11.3 percent reported on October 6, 2021. Throughout most of the pandemic, the Alaska Area had seen the lowest rate of COVID-19 cases within the IHS.

Overall, 9.0 percent of IHS tests have been positive since the onset of the pandemic, the data shows. Meanwhile, the 7-day average fell to 8.4 percent following a long period of high rates since 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, 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, although results were only provided on Monday during the week of December 5, 2021.

During the height of the pandemic throughout 2020 and the first half of 2021, results were provided by the IHS every day.
